Autophagy 2021 Feb 8:1-382. Epub 2021 Feb 8.

Hong Kong Baptist University, School of Chinese Medicine, Hong Kong, China.

In 2008, we published the first set of guidelines for standardizing research in autophagy. Since then, this topic has received increasing attention, and many scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Thus, it is important to formulate on a regular basis updated guidelines for monitoring autophagy in different organisms. Despite numerous reviews, there continues to be confusion regarding acceptable methods to evaluate autophagy, especially in multicellular eukaryotes. Here, we present a set of guidelines for investigators to select and interpret methods to examine autophagy and related processes, and for reviewers to provide realistic and reasonable critiques of reports that are focused on these processes. These guidelines are not meant to be a dogmatic set of rules, because the appropriateness of any assay largely depends on the question being asked and the system being used. Moreover, no individual assay is perfect for every situation, calling for the use of multiple techniques to properly monitor autophagy in each experimental setting. Finally, several core components of the autophagy machinery have been implicated in distinct autophagic processes (canonical and noncanonical autophagy), implying that genetic approaches to block autophagy should rely on targeting two or more autophagy-related genes that ideally participate in distinct steps of the pathway. Along similar lines, because multiple proteins involved in autophagy also regulate other cellular pathways including apoptosis, not all of them can be used as a specific marker for autophagic responses. Here, we critically discuss current methods of assessing autophagy and the information they can, or cannot, provide. Our ultimate goal is to encourage intellectual and technical innovation in the field.

Childhood maltreatment, serotonin transporter gene, and risk for callous and unemotional traits: A prospective investigation.

Psychiatry Res 2020 09 2;291:113271. Epub 2020 Jul 2.

Department of Genetics and Human Genetics Institute, Rutgers, The State University of New Jersey, 145 Bevier Road, Piscataway, NJ, 08854-8082, USA.

Previous studies have reported associations between the serotonin transporter 5-HTTLPR genotype and antisocial and aggressive traits and between child maltreatment and antisocial traits. However, few studies have examined whether 5-HTTLPR moderates the influence of childhood maltreatment on callous and unemotional traits, a hallmark of psychopathy. Using a prospective cohort design, children with documented cases of maltreatment and matched controls were followed up and interviewed in adulthood. DNA was extracted from blood and saliva (N = 414) and callous-unemotional (CU) traits were assessed. Childhood maltreatment predicted higher CU scores in adulthood, whereas the effect of 5-HTTLPR was not significant. The effect of child maltreatment on CU traits did not differ by genetic risk (high or low activity 5-HTTLPR), whereas controls with the LL genotype had higher CU scores than controls with the SS genotype. Similar results were found for females and White, non-Hispanics, but not for males and Blacks. Variations in 5-HTTLPR did not affect the impact of child maltreatment on CU traits in adulthood. Genetic risk had a stronger effect on adults with lower environmental risk (controls). Having a history of child maltreatment or the LL genotype placed participants at risk for higher levels of callous and unemotional trait scores.

Microbial communities in the tropical air ecosystem follow a precise diel cycle.

Proc Natl Acad Sci U S A 2019 11 28;116(46):23299-23308. Epub 2019 Oct 28.

Singapore Centre for Environmental Life Sciences Engineering, Nanyang Technological University, 637551 Singapore;

The atmosphere is vastly underexplored as a habitable ecosystem for microbial organisms. In this study, we investigated 795 time-resolved metagenomes from tropical air, generating 2.27 terabases of data. Despite only 9 to 17% of the generated sequence data currently being assignable to taxa, the air harbored a microbial diversity that rivals the complexity of other planetary ecosystems. The airborne microbial organisms followed a clear diel cycle, possibly driven by environmental factors. Interday taxonomic diversity exceeded day-to-day and month-to-month variation. Environmental time series revealed the existence of a large core of microbial taxa that remained invariable over 13 mo, thereby underlining the long-term robustness of the airborne community structure. Unlike terrestrial or aquatic environments, where prokaryotes are prevalent, the tropical airborne biomass was dominated by DNA from eukaryotic phyla. Specific fungal and bacterial species were strongly correlated with temperature, humidity, and CO concentration, making them suitable biomarkers for studying the bioaerosol dynamics of the atmosphere.

A Novel Mechanism To Prevent HS Toxicity in .

Genetics 2019 10 1;213(2):481-490. Epub 2019 Aug 1.

Department of Biochemistry, University of Washington School of Medicine, Seattle, Washington 98195

Hydrogen sulfide (HS) is an endogenously produced signaling molecule that can be cytoprotective, especially in conditions of ischemia/reperfusion injury. However, HS is also toxic, and unregulated accumulation or exposure to environmental HS can be lethal. In , the hypoxia inducible factor () coordinates the initial transcriptional response to HS, and is essential to survive exposure to low concentrations of HS. We performed a forward genetic screen to identify mutations that suppress the lethality of mutant animals in HS. The mutations we recovered are specific for HS, as they do not suppress embryonic lethality or reproductive arrest of mutant animals in hypoxia, nor can they prevent the death of mutant animals exposed to hydrogen cyanide. The majority of suppressor mutations we recovered activate the /Nrf2 transcription factor. Activation of SKN-1 by suppressor mutations increased the expression of a subset of HS-responsive genes, consistent with previous findings that plays a role in the transcriptional response to HS. Using transgenic rescue, we show that overexpression of a single gene, , is sufficient to protect mutant animals in HS. The gene encodes a predicated O-acyltransferase enzyme that has previously been shown to negatively regulate HIF-1 activity. Our data indicate that RHY-1 has novel, independent, function that promotes survival in HS.

Fasting prevents hypoxia-induced defects of proteostasis in C. elegans.

PLoS Genet 2019 06 27;15(6):e1008242. Epub 2019 Jun 27.

Department of Biochemistry, University of Washington School of Medicine, Seattle, United States of America.

Low oxygen conditions (hypoxia) can impair essential physiological processes and cause cellular damage and death. We have shown that specific hypoxic conditions disrupt protein homeostasis in C. elegans, leading to protein aggregation and proteotoxicity. Here, we show that nutritional cues regulate this effect of hypoxia on proteostasis. Animals fasted prior to hypoxic exposure develop dramatically fewer polyglutamine protein aggregates compared to their fed counterparts, indicating that the effect of hypoxia is abrogated. Fasting also reduced the hypoxia-induced exaggeration of proteostasis defects in animals that express Aβ1-42 and in animals with a temperature-sensitive mutation in dyn-1, suggesting that this effect was not specific to polyglutamine proteins. Our data also demonstrate that the nutritional environment experienced at the onset of hypoxia dictates at least some aspects of the physiological response to hypoxia. We further demonstrate that the insulin/IGF-like signaling pathway plays a role in mediating the protective effects of fasting in hypoxia. Animals with mutations in daf-2, the C. elegans insulin-like receptor, display wild-type levels of hypoxia-induced protein aggregation upon exposure to hypoxia when fed, but are not protected by fasting. DAF-2 acts independently of the FOXO transcription factor, DAF-16, to mediate the protective effects of fasting. These results suggest a non-canonical role for the insulin/IGF-like signaling pathway in coordinating the effects of hypoxia and nutritional state on proteostasis.

HIF-1 Is Broadly Required for Survival in Hydrogen Sulfide.

G3 (Bethesda) 2017 11 6;7(11):3699-3704. Epub 2017 Nov 6.

Hydrogen sulfide is common in the environment, and is also endogenously produced by animal cells. Although hydrogen sulfide is often toxic, exposure to low levels of hydrogen sulfide improves outcomes in a variety of mammalian models of ischemia-reperfusion injury. In , the initial transcriptional response to hydrogen sulfide depends on the transcription factor, and mutant animals die when exposed to hydrogen sulfide. In this study, we use rescue experiments to identify tissues in which is required to survive exposure to hydrogen sulfide. We find that expression of from the promoter is sufficient to survive hydrogen sulfide. Although is generally considered to be a pan-neuronal promoter, we show that it is active in many nonneuronal cells as well. Using other promoters, we show that pan-neuronal expression of is not sufficient to survive exposure to hydrogen sulfide. Our data suggest that is required in many different tissues to direct the essential response to hydrogen sulfide.

Two functionally distinct E2/E3 pairs coordinate sequential ubiquitination of a common substrate in development.

Proc Natl Acad Sci U S A 2017 08 24;114(32):E6576-E6584. Epub 2017 Jul 24.

Ubiquitination, the crucial posttranslational modification that regulates the eukaryotic proteome, is carried out by a trio of enzymes, known as E1 [ubiquitin (Ub)-activating enzyme], E2 (Ub-conjugating enzyme), and E3 (Ub ligase). Although most E2s can work with any of the three mechanistically distinct classes of E3s, the E2 UBCH7 is unable to function with really interesting new gene (RING)-type E3s, thereby restricting it to homologous to E6AP C-terminus (HECT) and RING-in-between-RING (RBR) E3s. The UBCH7 homolog, UBC-18, plays a critical role in developmental processes through its cooperation with the RBR E3 ARI-1 (HHARI in humans). We discovered that another E2, , interacts genetically with in an unbiased genome-wide RNAi screen in These two E2s have nonoverlapping biochemical activities, and each is dedicated to distinct classes of E3s. UBC-3 is the ortholog of CDC34 that functions specifically with Cullin-RING E3 ligases, such as SCF (Skp1-Cullin-F-box). Our genetic and biochemical studies show that UBCH7 (UBC-18) and the RBR E3 HHARI (ARI-1) coordinate with CDC34 (UBC-3) and an SCF E3 complex to ubiquitinate a common substrate, a SKP1-related protein. We show that UBCH7/HHARI primes the substrate with a single Ub in the presence of CUL-1, and that CDC34 is required to build chains onto the Ub-primed substrate. Our study reveals that the association and coordination of two distinct E2/E3 pairs play essential roles in a developmental pathway and suggests that cooperative action among E3s is a conserved feature from worms to humans.

Adaptation strategies to climate change in marine systems.

Glob Chang Biol 2018 01 17;24(1):e1-e14. Epub 2017 Aug 17.

OceanCanada Partnership, Institute for the Oceans and Fisheries & Liu Institute for Global Studies, The University of British Columbia, AERL, Vancouver, BC, Canada.

The world's oceans are highly impacted by climate change and other human pressures, with significant implications for marine ecosystems and the livelihoods that they support. Adaptation for both natural and human systems is increasingly important as a coping strategy due to the rate and scale of ongoing and potential future change. Here, we conduct a review of literature concerning specific case studies of adaptation in marine systems, and discuss associated characteristics and influencing factors, including drivers, strategy, timeline, costs, and limitations. We found ample evidence in the literature that shows that marine species are adapting to climate change through shifting distributions and timing of biological events, while evidence for adaptation through evolutionary processes is limited. For human systems, existing studies focus on frameworks and principles of adaptation planning, but examples of implemented adaptation actions and evaluation of outcomes are scarce. These findings highlight potentially useful strategies given specific social-ecological contexts, as well as key barriers and specific information gaps requiring further research and actions.

Computational Analysis of Lifespan Experiment Reproducibility.

Front Genet 2017 30;8:92. Epub 2017 Jun 30.

Department of Biochemistry, University of Washington School of MedicineSeattle, WA, United States.

Independent reproducibility is essential to the generation of scientific knowledge. Optimizing experimental protocols to ensure reproducibility is an important aspect of scientific work. Genetic or pharmacological lifespan extensions are generally small compared to the inherent variability in mean lifespan even in isogenic populations housed under identical conditions. This variability makes reproducible detection of small but real effects experimentally challenging. In this study, we aimed to determine the reproducibility of lifespan measurements under ideal conditions, in the absence of methodological errors or environmental or genetic background influences. To accomplish this, we generated a parametric model of lifespan based on data collected from 5,026 wild-type N2 animals. We use this model to predict how different experimental practices, effect sizes, number of animals, and how different "shapes" of survival curves affect the ability to reproduce real longevity effects. We find that the chances of reproducing real but small effects are exceedingly low and would require substantially more animals than are commonly used. Our results indicate that many lifespan studies are underpowered to detect reported changes and that, as a consequence, stochastic variation alone can account for many failures to reproduce longevity results. As a remedy, we provide power of detection tables that can be used as guidelines to plan experiments with statistical power to reliably detect real changes in lifespan and limit spurious false positive results. These considerations will improve best-practices in designing lifespan experiment to increase reproducibility.

MetaLIMS, a simple open-source laboratory information management system for small metagenomic labs.

Gigascience 2017 06;6(6):1-6

Background: As the cost of sequencing continues to fall, smaller groups increasingly initiate and manage larger sequencing projects and take on the complexity of data storage for high volumes of samples. This has created a need for low-cost laboratory information management systems (LIMS) that contain flexible fields to accommodate the unique nature of individual labs. Many labs do not have a dedicated information technology position, so LIMS must also be easy to setup and maintain with minimal technical proficiency. MetaLIMS is a free and open-source web-based application available via GitHub. The focus of MetaLIMS is to store sample metadata prior to sequencing and analysis pipelines. Initially designed for environmental metagenomics labs, in addition to storing generic sample collection information and DNA/RNA processing information, the user can also add fields specific to the user's lab. MetaLIMS can also produce a basic sequencing submission form compatible with the proprietary Clarity LIMS system used by some sequencing facilities. To help ease the technical burden associated with web deployment, MetaLIMS options the use of commercial web hosting combined with MetaLIMS bash scripts for ease of setup. MetaLIMS overcomes key challenges common in LIMS by giving labs access to a low-cost and open-source tool that also has the flexibility to meet individual lab needs and an option for easy deployment. By making the web application open source and hosting it on GitHub, we hope to encourage the community to build upon MetaLIMS, making it more robust and tailored to the needs of more researchers.

Impact of High Seas Closure on Food Security in Low Income Fish Dependent Countries.

PLoS One 2016 29;11(12):e0168529. Epub 2016 Dec 29.

Fisheries Economics Research Unit, Institute for the Oceans and Fisheries, The University of British Columbia, Vancouver, Canada.

We investigate how high seas closure will affect the availability of commonly consumed food fish in 46 fish reliant, and/or low income countries. Domestic consumption of straddling fish species (fish that would be affected by high seas closure) occurred in 54% of the assessed countries. The majority (70%) of countries were projected to experience net catch gains following high seas closure. However, countries with projected catch gains and that also consumed the straddling fish species domestically made up only 37% of the assessed countries. In contrast, much fewer countries (25%) were projected to incur net losses from high seas closure, and of these, straddling species were used domestically in less than half (45%) of the countries. Our findings suggest that, given the current consumption patterns of straddling species, high seas closure may only directly benefit the supply of domestically consumed food fish in a small number of fish reliant and/or low income countries. In particular, it may not have a substantial impact on improving domestic fish supply in countries with the greatest need for improved access to affordable fish, as only one third of this group used straddling fish species domestically. Also, food security in countries with projected net catch gains but where straddling fish species are not consumed domestically may still benefit indirectly via economic activities arising from the increased availability of non-domestically consumed straddling fish species following high seas closure. Consequently, this study suggests that high seas closure can potentially improve marine resource sustainability as well as contribute to human well-being in some of the poorest and most fish dependent countries worldwide. However, caution is required because high seas closure may also negatively affect fish availability in countries that are already impoverished and fish insecure.

Mitochondrial Sulfide Quinone Oxidoreductase Prevents Activation of the Unfolded Protein Response in Hydrogen Sulfide.

J Biol Chem 2016 Mar 16;291(10):5320-5. Epub 2015 Dec 16.

Hydrogen sulfide (H2S) is an endogenously produced gaseous molecule with important roles in cellular signaling. In mammals, exogenous H2S improves survival of ischemia/reperfusion. We have previously shown that exposure to H2S increases the lifespan and thermotolerance in Caenorhabditis elegans, and improves protein homeostasis in low oxygen. The mitochondrial SQRD-1 (sulfide quinone oxidoreductase) protein is a highly conserved enzyme involved in H2S metabolism. SQRD-1 is generally considered important to detoxify H2S. Here, we show that SQRD-1 is also required to maintain protein translation in H2S. In sqrd-1 mutant animals, exposure to H2S leads to phosphorylation of eIF2α and inhibition of protein synthesis. In contrast, global protein translation is not altered in wild-type animals exposed to lethally high H2S or in hif-1(ia04) mutants that die when exposed to low H2S. We demonstrate that both gcn-2 and pek-1 kinases are involved in the H2S-induced phosphorylation of eIF2α. Both ER and mitochondrial stress responses are activated in sqrd-1 mutant animals exposed to H2S, but not in wild-type animals. We speculate that SQRD-1 activity in H2S may coordinate proteostasis responses in multiple cellular compartments.

Protocol Improvements for Low Concentration DNA-Based Bioaerosol Sampling and Analysis.

PLoS One 2015 30;10(11):e0141158. Epub 2015 Nov 30.

SinBerBEST Program, Berkeley Education Alliance for Research in Singapore, Singapore.

Introduction: As bioaerosol research attracts increasing attention, there is a need for additional efforts that focus on method development to deal with different environmental samples. Bioaerosol environmental samples typically have very low biomass concentrations in the air, which often leaves researchers with limited options in choosing the downstream analysis steps, especially when culture-independent methods are intended.

Objectives: This study investigates the impacts of three important factors that can influence the performance of culture-independent DNA-based analysis in dealing with bioaerosol environmental samples engaged in this study. The factors are: 1) enhanced high temperature sonication during DNA extraction; 2) effect of sampling duration on DNA recoverability; and 3) an alternative method for concentrating composite samples. In this study, DNA extracted from samples was analysed using the Qubit fluorometer (for direct total DNA measurement) and quantitative polymerase chain reaction (qPCR).

Results And Findings: The findings suggest that additional lysis from high temperature sonication is crucial: DNA yields from both high and low biomass samples increased up to 600% when the protocol included 30-min sonication at 65°C. Long air sampling duration on a filter media was shown to have a negative impact on DNA recoverability with up to 98% of DNA lost over a 20-h sampling period. Pooling DNA from separate samples during extraction was proven to be feasible with margins of error below 30%.

Cell nonautonomous activation of flavin-containing monooxygenase promotes longevity and health span.

Science 2015 Dec 19;350(6266):1375-1378. Epub 2015 Nov 19.

Department of Pathology, University of Washington, Seattle, WA 98195, USA.

Stabilization of the hypoxia-inducible factor 1 (HIF-1) increases life span and health span in nematodes through an unknown mechanism. We report that neuronal stabilization of HIF-1 mediates these effects in Caenorhabditis elegans through a cell nonautonomous signal to the intestine, which results in activation of the xenobiotic detoxification enzyme flavin-containing monooxygenase-2 (FMO-2). This prolongevity signal requires the serotonin biosynthetic enzyme TPH-1 in neurons and the serotonin receptor SER-7 in the intestine. Intestinal FMO-2 is also activated by dietary restriction (DR) and is necessary for DR-mediated life-span extension, which suggests that this enzyme represents a point of convergence for two distinct longevity pathways. FMOs are conserved in eukaryotes and induced by multiple life span-extending interventions in mice, which suggests that these enzymes may play a critical role in promoting health and longevity across phyla.

Tissue-specific autophagy responses to aging and stress in C. elegans.

Aging (Albany NY) 2015 Jun;7(6):419-34

Department of Biochemistry, University of Washington, Seattle, WA 98195, USA.

Cellular function relies on a balance between protein synthesis and breakdown. Macromolecular breakdown through autophagy is broadly required for cellular and tissue development, function, and recovery from stress. While Caenorhabditis elegans is frequently used to explore cellular responses to development and stress, the most common assays for autophagy in this system lack tissue-level resolution. Different tissues within an organism have unique functional characteristics and likely vary in their reliance on autophagy under different conditions. To generate a tissue-specific map of autophagy in C. elegans we used a dual fluorescent protein (dFP) tag that releases monomeric fluorescent protein (mFP) upon arrival at the lysosome. Tissue-specific expression of dFP::LGG-1 revealed autophagic flux in all tissues, but mFP accumulation was most dramatic in the intestine. We also observed variable responses to stress: starvation increased autophagic mFP release in all tissues, whereas anoxia primarily increased intestinal autophagic flux. We observed autophagic flux with tagged LGG-1, LGG-2, and two autophagic cargo reporters: a soluble cytoplasmic protein, and mitochondrial TOMM-7. Finally, an increase in mFP in older worms was consistent with an age-dependent shift in proteostasis. These novel measures of autophagic flux in C. elegans reveal heterogeneity in autophagic response across tissues during stress and aging.

Winners and losers in a world where the high seas is closed to fishing.

Sci Rep 2015 Feb 12;5:8481. Epub 2015 Feb 12.

Sea Around Us, Fisheries Centre, University of British Columbia, Vancouver, British Columbia, V6T 1Z4, Canada.

Fishing takes place in the high seas and Exclusive Economic Zones (EEZs) of maritime countries. Closing the former to fishing has recently been proposed in the literature and is currently an issue of debate in various international fora. We determine the degree of overlap between fish caught in these two areas of the ocean, examine how global catch might change if catches of straddling species or taxon groups increase within EEZs as a result of protection of adjacent high seas; and identify countries that are likely to gain or lose in total catch quantity and value following high-seas closure. We find that <0.01% of the quantity and value of commercial fish taxa are obtained from catch taken exclusively in the high seas, and if the catch of straddling taxa increases by 18% on average following closure because of spillover, there would be no loss in global catch. The Gini coefficient, which measures income inequality, would decrease from 0.66 to 0.33. Thus, closing the high seas could be catch-neutral while inequality in the distribution of fisheries benefits among the world's maritime countries could be reduced by 50%.

Hypoxia disrupts proteostasis in Caenorhabditis elegans.

Aging Cell 2015 Feb 16;14(1):92-101. Epub 2014 Dec 16.

Graduate Program in Molecular and Cellular Biology, University of Washington School of Medicine, Seattle, WA, 98195-7350, USA.

Oxygen is fundamentally important for cell metabolism, and as a consequence, O₂ deprivation (hypoxia) can impair many essential physiological processes. Here, we show that an active response to hypoxia disrupts cellular proteostasis - the coordination of protein synthesis, quality control, and degradation that maintains the functionality of the proteome. We have discovered that specific hypoxic conditions enhance the aggregation and toxicity of aggregation-prone proteins that are associated with neurodegenerative diseases. Our data indicate this is an active response to hypoxia, rather than a passive consequence of energy limitation. This response to hypoxia is partially antagonized by the conserved hypoxia-inducible transcription factor, hif-1. We further demonstrate that exposure to hydrogen sulfide (H₂S) protects animals from hypoxia-induced disruption of proteostasis. H₂S has been shown to protect against hypoxic damage in mammals and extends lifespan in nematodes. Remarkably, our data also show that H₂S can reverse detrimental effects of hypoxia on proteostasis. Our data indicate that the protective effects of H₂S in hypoxia are mechanistically distinct from the effect of H₂S to increase lifespan and thermotolerance, suggesting that control of proteostasis and aging can be dissociated. Together, our studies reveal a novel effect of the hypoxia response in animals and provide a foundation to understand how the integrated proteostasis network is integrated with this stress response pathway.

Hand bacterial communities vary across two different human populations.

Microbiology (Reading) 2014 Jun 11;160(Pt 6):1144-1152. Epub 2014 May 11.

Department of Chemical and Environmental Engineering, Yale University, New Haven, CT 06520, USA.

This study utilized pyrosequencing-based phylogenetic library results to assess bacterial communities on the hands of women in Tanzania and compared these communities with bacteria assemblages on the hands of US women. Bacterial population profiles and phylogenetically based ordinate analysis demonstrated that the bacterial communities on hands were more similar for selected populations within a country than between the two countries considered. Organisms that have commonly been identified in prior human skin microbiome studies, including members of the Propionibacteriaceae, Staphylococcaceae and Streptococceacea families, were highly abundant on US hands and drove the clustering of US hand microbial communities into a distinct group. The most abundant bacterial taxa on Tanzanian hands were the soil-associated Rhodobacteraceae and Nocardioidaceae. These results help to expand human microbiome results beyond US and European populations, and the identification and abundance of soil-associated bacteria on Tanzanian hands demonstrated the important role of the environment in shaping the microbial communities on human hands.

Mandating responsible flagging practices as a strategy for reducing the risk of coastal oil spills.

Mar Pollut Bull 2014 Apr 24;81(1):24-6. Epub 2014 Jan 24.

Fisheries Economics Research Unit, Fisheries Centre, 2202 Main Mall, University of British Columbia, Vancouver, BC V6T 1Z4, Canada.

As human civilization is becoming more aware of the negative impact our actions can inflict upon the natural world, the intensification of fossil fuel extraction and industrial development is being met with increasing opposition. In Western Canada, proposals that would increase the volume of petroleum transported by pipelines and by tankers through the coastal waters of British Columbia have engaged the province in debate. To ease public concern on the risk of a coastal oil spill, there are additional commitments that involved parties could make. There is evidence to show that the practice of registering vessels under foreign flags of states that have exhibited failure in compliance with international obligations is more common amongst petroleum tankers that have been involved in large-scale oil spills. To prove that they are committed to reducing the risk of oil spills, businesses need to stop registering their vessels under flags of foreign, non-compliant states.

DNA barcoding unveils skate (Chondrichthyes: Rajidae) species diversity in 'ray' products sold across Ireland and the UK.

PeerJ 2013 13;1:e129. Epub 2013 Aug 13.

School of Environment and Life Sciences, University of Salford, Greater Manchester, UK.

Skates are widely consumed across the globe, but many large species are subject to considerable concern regarding their conservation and management. Within Europe such issues have recently driven policy changes so that, for the first time, reports of skate landings now have to be made under species-specific names. Total allowable catches have also been established for many groups, which have been set to zero for a number of the most vulnerable species (e.g., Dipturus batis, Raja undulata and Rostoraja alba). Whilst accurate species identification has become an important issue for landings, the sale of skates is still usually made under a blanket term of "skate" or "ray". The matter of identifying species of skate is further complicated by their morphologically conservative nature and the fact that they are commercially valued for their wings. Thus, before sale their bodies are usually discarded (i.e., "winged") and often skinned, making morphological identification impossible. For the first time, DNA barcoding (of the mitochondrial COI gene) was applied to samples of skate wings from retail outlets across the British Isles, providing insight into which species are sold for consumption. A total of 98 wing samples were analysed, revealing that six species were sold; blonde ray (Raja brachyura), spotted ray (Raja montagui), thornback ray (Raja clavata), cuckoo ray (Leucoraja naevus) small-eyed ray (Raja microocellata) and shagreen ray (Leucoraja fullonica). Statistical testing demonstrated that there were significant differences in the species sold in the distinct retail groups which suggests complex drivers behind the patterns of sale in skates. The results also indicate that endangered species are not commonly being passed on to consumers. In addition, the practice of selling skate wings under ambiguous labels is highlighted as it makes it extremely difficult for consumers to exercise a right to avoid species of conservation concern. Interestingly, a single retailer chain labelled their wings as originating from three smaller-growing species (generally to be considered of lower conservation concern); of the six samples analysed from this company a third were mislabelled and originated from the thornback ray (a larger species that is currently undergoing population declines).

Interactions between oxygen homeostasis, food availability, and hydrogen sulfide signaling.

Front Genet 2012 27;3:257. Epub 2012 Nov 27.

Department of Biochemistry, University of Washington School of Medicine Seattle, WA, USA ; Molecular and Cellular Biology Graduate Program, University of Washington School of Medicine Seattle, WA, USA.

The ability to sense and respond to stressful conditions is essential to maintain organismal homeostasis. It has long been recognized that stress response factors that improve survival in changing conditions can also influence longevity. In this review, we discuss different strategies used by animals in response to decreased O(2) (hypoxia) to maintain O(2) homeostasis, and consider interactions between hypoxia responses, nutritional status, and H(2)S signaling. O(2) is an essential environmental nutrient for almost all metazoans as it plays a fundamental role in development and cellular metabolism. However, the physiological response(s) to hypoxia depend greatly on the amount of O(2) available. Animals must sense declining O(2) availability to coordinate fundamental metabolic and signaling pathways. It is not surprising that factors involved in the response to hypoxia are also involved in responding to other key environmental signals, particularly food availability. Recent studies in mammals have also shown that the small gaseous signaling molecule hydrogen sulfide (H(2)S) protects against cellular damage and death in hypoxia. These results suggest that H(2)S signaling also integrates with hypoxia response(s). Many of the signaling pathways that mediate the effects of hypoxia, food deprivation, and H(2)S signaling have also been implicated in the control of lifespan. Understanding how these pathways are coordinated therefore has the potential to reveal new cellular and organismal homeostatic mechanisms that contribute to longevity assurance in animals.

Creating defined gaseous environments to study the effects of hypoxia on C. elegans.

J Vis Exp 2012 Jul 20(65):e4088. Epub 2012 Jul 20.

Department of Biochemistry, University of Washington, USA.

Oxygen is essential for all metazoans to survive, with one known exception. Decreased O(2) availability (hypoxia) can arise during states of disease, normal development or changes in environmental conditions. Understanding the cellular signaling pathways that are involved in the response to hypoxia could provide new insight into treatment strategies for diverse human pathologies, from stroke to cancer. This goal has been impeded, at least in part, by technical difficulties associated with controlled hypoxic exposure in genetically amenable model organisms. The nematode Caenorhabditis elegans is ideally suited as a model organism for the study of hypoxic response, as it is easy to culture and genetically manipulate. Moreover, it is possible to study cellular responses to specific hypoxic O(2) concentrations without confounding effects since C. elegans obtain O(2) (and other gasses) by diffusion, as opposed to a facilitated respiratory system. Factors known to be involved in the response to hypoxia are conserved in C. elegans. The actual response to hypoxia depends on the specific concentration of O(2) that is available. In C. elegans, exposure to moderate hypoxia elicits a transcriptional response mediated largely by hif-1, the highly-conserved hypoxia-inducible transcription factor. C .elegans embryos require hif-1 to survive in 5,000-20,000 ppm O(2). Hypoxia is a general term for "less than normal O(2)". Normoxia (normal O(2)) can also be difficult to define. We generally consider room air, which is 210,000 ppm O(2) to be normoxia. However, it has been shown that C. elegans has a behavioral preference for O(2) concentrations from 5-12% (50,000-120,000 ppm O(2)). In larvae and adults, hif-1 acts to prevent hypoxia-induced diapause in 5,000 ppm O(2). However, hif-1 does not play a role in the response to lower concentrations of O(2) (anoxia, operational definition <10 ppm O(2)). In anoxia, C. elegans enters into a reversible state of suspended animation in which all microscopically observable activity ceases. The fact that different physiological responses occur in different conditions highlights the importance of having experimental control over the hypoxic concentration of O(2). Here, we present a method for the construction and implementation of environmental chambers that produce reliable and reproducible hypoxic conditions with defined concentrations of O(2). The continual flow method ensures rapid equilibration of the chamber and increases the stability of the system. Additionally, the transparency and accessibility of the chambers allow for direct visualization of animals being exposed to hypoxia. We further demonstrate an effective method of harvesting C. elegans samples rapidly after exposure to hypoxia, which is necessary to observe many of the rapidly-reversed changes that occur in hypoxia. This method provides a basic foundation that can be easily modified for individual laboratory needs, including different model systems and a variety of gasses.

HIF-1 and SKN-1 coordinate the transcriptional response to hydrogen sulfide in Caenorhabditis elegans.

PLoS One 2011 29;6(9):e25476. Epub 2011 Sep 29.

Department of Biochemistry, University of Washington School of Medicine, Seattle, Washington, United States of America.

Hydrogen sulfide (H₂S) has dramatic physiological effects on animals that are associated with improved survival. C. elegans grown in H₂S are long-lived and thermotolerant. To identify mechanisms by which adaptation to H₂S effects physiological functions, we have measured transcriptional responses to H₂S exposure. Using microarray analysis we observe rapid changes in the abundance of specific mRNAs. The number and magnitude of transcriptional changes increased with the duration of H₂S exposure. Functional annotation suggests that genes associated with protein homeostasis are upregulated upon prolonged exposure to H₂S. Previous work has shown that the hypoxia-inducible transcription factor, HIF-1, is required for survival in H₂S. In fact, we show that hif-1 is required for most, if not all, early transcriptional changes in H₂S. Moreover, our data demonstrate that SKN-1, the C. elegans homologue of NRF2, also contributes to H₂S-dependent changes in transcription. We show that these results are functionally important, as skn-1 is essential to survive exposure to H₂S. Our results suggest a model in which HIF-1 and SKN-1 coordinate a broad transcriptional response to H₂S that culminates in a global reorganization of protein homeostasis networks.

C. elegans are protected from lethal hypoxia by an embryonic diapause.

Curr Biol 2009 Jul 2;19(14):1233-7. Epub 2009 Jul 2.

Fred Hutchinson Cancer Research Center, Seattle, WA 98109, USA.

At least 100 mammalian species exhibit embryonic diapause, where fertilized embryos arrest development in utero until suitable seasonal or nutritional environments are encountered. Delaying maternal investments in producing offspring allows these animals to utilize limited resources to survive while searching for better conditions and ensures that progeny are not produced when they are unlikely to survive. In addition, embryos may be protected from external environmental vicissitudes while in utero. Here we demonstrate embryonic diapause in C. elegans, and show that this diapause protects embryos from otherwise lethal hypoxia. Diapausing embryos in utero require san-1 to survive, indicating that hypoxia-induced embryonic diapause may be mechanistically related to suspended animation. Furthermore, we show that neuronal HIF-1 activity in the adult dictates the O(2) tension at which embryonic diapause is engaged. We suggest that the maternal perception of hypoxia stimulates a response to protect embryos in utero by inducing diapause, a natural form of suspended animation. This response is likely to be an important strategy to improve offspring survival in harsh conditions and allow adults to find environments more suitable for reproductive success.

How adolescents experience smoking cessation.

Qual Health Res 2009 May;19(5):580-92

University of Nebraska Medical Center, Omaha, Nebraska, USA.

In this study we develop a model of how youth experience smoking cessation attempts. We followed 15 adolescent smokers twice monthly over three months. Through six semistructured interviews, we explored participants' subjective experiences of making a "quit" attempt. We analyzed transcript data using grounded theory procedures, beginning with open coding, axial coding, construction of matrices, and development of a preliminary theory or model of this phenomenon. We found that only emotionally compelling and inescapable quit reasons were truly motivating. Few parents actively supported their child during quit attempts; smoking friends and other peers undermined them. All successful quitters established new, nonsmoking friends and completely redefined themselves. The quit experience was physically uncomfortable, emotionally distressful, and socially isolating. Greater motivation, mature problem-solving skills, and a willingness to supplant their smoking friends characterized successful quitters. Further research is needed to test this model's efficacy in the adolescent population.
