Early-life exposure to the endocrine disruptor 17-α-ethinylestradiol induces delayed effects in adult brain, liver and ovotestis proteomes of a self-fertilizing fish.

J Proteomics 2018 Dec 11. Epub 2018 Dec 11.

Laboratory of Evolutionary and Adaptive Physiology - Institute of Life, Earth and Environment - University of Namur, 61 Rue de Bruxelles, B5000 Namur, Belgium.

Early-life represents a critically sensitive window to endocrine disrupting chemicals, potentially leading to long-term repercussions on the phenotype later in life. The mechanisms underlying this phenomenon, referred to as the Developmental Origins of Health and Disease (DOHaD), are still poorly understood. To gain molecular understanding of these effects, we exposed mangrove rivulus (Kryptolebias marmoratus) for 28 days post hatching (dph) to 4 and 120 ng/L 17-α-ethinylestradiol, a model xenoestrogen.

Circular RNAs (circRNAs) are a novel class of regulatory RNAs that despite being relatively abundant have only recently begun to be explored. There are many thousands of genes that appear capable of producing circRNAs, however the function of all but a handful remain to be determined. What is emerging about these highly conserved molecules is that they play important roles in biology and cancer biology in particular. Read More

Characterization of locomotor response to psychostimulants in the parthenogenetic marbled crayfish (Procambarus fallax forma virginalis): A promising model for studying the neural and molecular mechanisms of drug addiction.

Behav Brain Res 2018 Dec 11. Epub 2018 Dec 11.

J.P. Scott Center for Neuroscience, Mind & Behavior, and Department of Biological Sciences, Bowling Green State University, Bowling Green, OH 43403, USA.

Although scientific research using mammalian models has made great strides in uncovering the enigmatic neural and molecular mechanisms orchestrating the state of drug addiction, a complete understanding has thus far eluded researchers. The complexity of the task has led to the use of invertebrate model systems to complement the research of drug-induced reward in mammalian systems. Invertebrates, such as crayfish, offer excellent model systems to help reveal the underlying mechanisms of drug addiction as they retain the ancestral neural reward circuit that is evolutionarily conserved across taxa, and they possess relatively few, large neurons, laid out in an accessible, modularly organized nervous system.

CARM1 and Paraspeckles Regulate Pre-implantation Mouse Embryo Development.

Cell 2018 Dec;175(7):1902-1916.e13

Department of Physiology, Development and Neuroscience, University of Cambridge, Downing Street, Cambridge CB2 3EG, UK. Electronic address:

Nuclear architecture has never been carefully examined during early mammalian development at the stages leading to establishment of the embryonic and extra-embryonic lineages. Heterogeneous activity of the methyltransferase CARM1 during these stages results in differential methylation of histone H3R26 to modulate establishment of these two lineages. Here we show that CARM1 accumulates in nuclear granules at the 2- to 4-cell stage transition in the mouse embryo, with the majority corresponding to paraspeckles. Read More

Glandular defects in the mouse uterus with sustained activation of TGF-beta signaling is associated with altered differentiation of endometrial stromal cells and formation of stromal compartment.

PLoS One 2018 14;13(12):e0209417. Epub 2018 Dec 14.

Department of Veterinary Integrative Biosciences, Texas A&M University, College Station, Texas, United States of America.

Uterine gland development, also known as adenogenesis, is a key uterine morphogenic process indispensable for normal uterine function and fertility. Our earlier studies have reported that overactivation of TGFB receptor 1 (TGFBR1) in the mouse uterus using progesterone receptor (Pgr)-Cre recombinase causes female infertility, defective decidualization, and reduced uterine gland formation, a developmental milestone of postnatal uterus. To understand mechanisms that underpin the disrupted uterine gland formation in mice with sustained activation of TGFBR1, we raised the question of whether early postnatal adenogenesis was compromised in these mice.

How does intrauterine crowding affect locomotor performance in newborn pigs? A study of force generating capacity and muscle composition of the hind limb.

PLoS One 2018 14;13(12):e0209233. Epub 2018 Dec 14.

Laboratory of Functional Morphology, Department of Biology, Faculty of Sciences, University of Antwerp, Wilrijk, Belgium.

Intrauterine crowding (IUC) considerably influences postnatal traits in a polytocous species such as the pig. Previously, our group described how IUC affects locomotion during the piglet's first days of life (until 96 h after birth). We noted a reduced motor performance in piglets with a low birth weight and low vitality (L piglets), compared to piglets with a normal birth weight and normal vitality (N piglets), indicating L piglets are unable to produce enough force.

A common view among ancient historians about Roman attentiveness to children's psychological development needs reconsideration. The view holds that Romans ignored children's cognitive ontogeny, perceiving early childhood as a largely undifferentiated life stage. A separate but related issue is the problematic claim that Roman childhood was entirely a matter of social construction. Read More

Macromolecular crowding as a means to assess the effectiveness of chondrogenic media.

J Tissue Eng Regen Med 2018 Dec 14. Epub 2018 Dec 14.

Regenerative, Modular & Developmental Engineering Laboratory (REMODEL), Biomedical Sciences Building, National University of Ireland Galway (NUI Galway), Galway, Ireland.

Chondrocyte-based tissue engineering requires in vitro cell expansion, which is associated with phenotypic losses, decrease in collagen II synthesis and increase in collagen I synthesis. Another major obstacle in clinical translation of chondrocyte-based therapies is the lack of extracellular matrix (ECM) in the engineered cartilage substitutes. Various research and commercially available media claim that can maintain chondrogenic phenotype, whilst macromolecular crowding (MMC) has been shown to increase tissue-specific ECM deposition and to maintain cell phenotype in vitro.

The sensitivity of the forest carbon budget shifts across processes along with stand development and climate change.

Ecol Appl 2018 Dec 14. Epub 2018 Dec 14.

National Research Council of Italy, Institute for Agriculture and Forestry Systems, in the Mediterranean (CNR-ISAFOM), 87036, Rende, CS, Italy.

The future trajectory of atmospheric CO concentration depends on the development of the terrestrial carbon sink, which in turn is influenced by forest dynamics under changing environmental conditions. An in-depth understanding of model sensitivities and uncertainties in non steady-state conditions is necessary for reliable and robust projections of forest development and under scenarios of global warming and CO -enrichment. Here, we systematically assessed if a bio-geochemical process-based model (3D-CMCC-CNR), which embeds similarities with many other vegetation models, applied in simulating net primary productivity (NPP) and standing woody biomass (SWB), maintained a consistent sensitivity to its 55 input parameters through time, during forest-ageing and -structuring as well as under climate-change scenarios.

Detecting neurodevelopomental effects of early-gestation ethanol exposure: a non-human primate model of ethanol drinking during pregnancy.

Alcohol Clin Exp Res 2018 Dec 14. Epub 2018 Dec 14.

Division of Neuroscience, Oregon National Primate Research Center, Beaverton, OR.

Introduction: Gestational ethanol exposure is associated with multiple developmental abnormalities, collectively termed fetal alcohol spectrum disorder (FASD). While the majority of women abstain from ethanol following knowledge of pregnancy, one contributing factor to the high FASD prevalence is that pregnancy is not detected until 4-6 weeks. Thus, ethanol consumption continues during the initial stages of fetal development. Read More

RanGAP-mediated nucleocytoplasmic transport of Prospero regulates neural stem cell lifespan in Drosophila larval central brain.

Aging Cell 2018 Dec 13:e12854. Epub 2018 Dec 13.

Division of Human Reproduction and Developmental Genetics, The Women's Hospital, School of Medicine, Zhejiang University, Hangzhou, China.

By the end of neurogenesis in Drosophila pupal brain neuroblasts (NBs), nuclear Prospero (Pros) triggers cell cycle exit and terminates NB lifespan. Here, we reveal that in larval brain NBs, an intrinsic mechanism facilitates import and export of Pros across the nuclear envelope via a Ran-mediated nucleocytoplasmic transport system. In rangap mutants, the export of Pros from the nucleus to cytoplasm is impaired and the nucleocytoplasmic transport of Pros becomes one-way traffic, causing an early accumulation of Pros in the nuclei of the larval central brain NBs.

Sublaminar organization of the human subplate: developmental changes in the distribution of neurons, glia, growing axons and extracellular matrix.

J Anat 2018 Dec 13. Epub 2018 Dec 13.

Croatian Institute for Brain Research, School of Medicine, University of Zagreb, Zagreb, Croatia.

The objective of this paper was to collect normative data essential for analyzing the subplate (SP) role in pathogenesis of developmental disorders, characterized by abnormal circuitry, such as hypoxic-ischemic lesions, autism and schizophrenia. The main cytological features of the SP, such as low cell density, early differentiation of neurons and glia, plexiform arrangement of axons and dendrites, presence of synapses and a large amount of extracellular matrix (ECM) distinguish this compartment from the cell-dense cortical plate (CP; towards pia) and large fiber bundles of external axonal strata of fetal white matter (towards ventricle). For SP delineation from these adjacent layers based on combined cytological criteria, we analyzed the sublaminar distribution of different microstructural elements and the associated maturational gradients throughout development, using immunocytochemical and histological techniques on postmortem brain material (Zagreb Neuroembryological Collection).

Results are presented for bifenthrin in a rat developmental neurotoxicity (DNT) study along with effects on Na currents in human VGSC subtypes. Molecular modeling comparisons were also made for bifenthrin and other pyrethroids. Read More

The developmental relations between spatial cognition and mathematics in primary school children.

Dev Sci 2018 Dec 13:e12786. Epub 2018 Dec 13.

School of Psychology, University of Surrey, Guilford, Surrey, GU27XH, UK.

Spatial thinking is an important predictor of mathematics. However, existing data do not determine whether all spatial sub-domains are equally important for mathematics outcomes nor whether mathematics-spatial associations vary through development. This study addresses these questions by exploring the developmental relations between mathematics and spatial skills in children aged 6 -10 years (N = 155). Read More

Endocytosis acts as transport pathway in wood.

New Phytol 2018 Dec 12. Epub 2018 Dec 12.

Department of Plant Developmental Biology, Institute of Experimental Biology, Faculty of Biological Sciences, University of Wrocław, Kanonia 6/8, 50-328, Wrocław, Poland.

In trees, dead and living cells of secondary xylem (wood) function collectively, rendering cell-to-cell communication challenging. Water and solutes are transported over long distances from the roots to the aboveground organs via vessels, the main component of wood, and then radially over short distances to the neighboring cells. This enables proper functioning of trees and integrates whole-plant activity. Read More

Developmental exposure to psychostimulant primes activity-dependent gene induction in frontal cortex.

Dev Neurobiol 2018 Dec 12. Epub 2018 Dec 12.

Unit on Neural Circuits and Adaptive Behaviors, National Institute of Mental Health, National Institutes of Health, Bethesda, MD, 20892, USA.

Perinatal neurodevelopment involves extensive formation of neural connections and onset of activity-dependent gene expression for synaptic function and plasticity. Exposure to psychostimulants at this stage imposes significant risks for developing cognitive and affective disorders later in life. However, how developmental exposure to psychostimulants may induce long lasting molecular changes relevant to neural circuit function remains incompletely understood. Read More

The insights into molecular pathways of hypoxia-inducible factor in the brain.

J Neurosci Res 2018 Dec 12. Epub 2018 Dec 12.

Departments of Anesthesiology and Physiology, School of Medicine, Loma Linda University, Loma Linda, California.

The objectives of this present work were to review recent developments on the role of hypoxia-inducible factor (HIF) in the survival of cells under normoxic versus hypoxic and inflammatory brain conditions. The dual nature of HIF effects appears well established, based on the accumulated evidence of HIF playing both the role of adaptive factor and mediator of cell demise. Cellular HIF responses depend on pathophysiological conditions, developmental phase, comorbidities, and administered medications. Read More

Evolution of the Torso activation cassette, a pathway required for terminal patterning and moulting.

Insect Mol Biol 2018 Dec 12. Epub 2018 Dec 12.

Laboratory for Evolution and Development, Genomics Aotearoa, Biochemistry Department, University of Otago, P.O. Box 56, Dunedin, Aotearoa, New Zealand.

Embryonic terminal patterning and moulting are critical developmental processes in insects. In Drosophila and Tribolium both of these processes are regulated by the Torso-activation cassette (TAC). The TAC consists of a common receptor, Torso, ligands Trunk and PTTH, and the spatially restricted protein Torso-like, with combinations of these elements acting mechanistically to activate the receptor in different developmental contexts.

Neuroanatomical correlates of sensory deficits in children with neonatal arterial ischemic stroke.

Dev Med Child Neurol 2018 Dec 12. Epub 2018 Dec 12.

Department of Neurology, University of California, San Francisco, CA, USA.

Aim: Our aim was to characterize the sensory processing outcome following neonatal arterial ischemic stroke (NAIS) and identify neuroanatomical correlates of abnormal sensory processing.

Method: We evaluated children with NAIS longitudinally at 12 months, 18 months, and/or 30 months in areas of cognitive, motor, and language development. We gathered sensory processing data using the Sensory Profile-2 Caregiver Questionnaire. Read More

Downregulation of tyrosine hydroxylase phenotype after AAV injection above substantia nigra: Caution in experimental models of Parkinson's disease.

J Neurosci Res 2018 Dec 12. Epub 2018 Dec 12.

Institute of Biotechnology, Program of Developmental Biology, University of Helsinki, Helsinki, Finland.

Adeno-associated virus (AAV) vector-mediated delivery of human α-synuclein (α-syn) gene in rat substantia nigra (SN) results in increased expression of α-syn protein in the SN and striatum which can progressively degenerate dopaminergic neurons. Therefore, this model is thought to recapitulate the neurodegeneration in Parkinson's disease. Here, using AAV to deliver α-syn above the SN in male and female rats resulted in clear expression of human α-syn in the SN and striatum. Read More
