J Biol Chem 2021 Sep 15:101199. Epub 2021 Sep 15.

Laboratory of Fish Molecular Immunology, College of Fisheries and Life Science, Shanghai Ocean University, Shanghai, China; Laboratory of Marine Biology and Biotechnology, Qingdao National Laboratory for Marine Science and Technology, Qingdao, China; Key Laboratory of Exploration and Utilization of Aquatic Genetic Resources (Shanghai Ocean University), Ministry of Education, China; National Pathogen Collection Center for Aquatic Animals, Shanghai Ocean University, Shanghai, China. Electronic address:

Growing numbers of studies have shown that circular RNAs (circRNAs) can function as regulatory factors to regulate the innate immune response, cell proliferation, cell migration, and other important processes in mammals. However, the function and regulatory mechanism of circRNAs in lower vertebrates are still unclear. Here, we discovered a novel circRNA derived from the gene encoding Bcl-2-like protein 1 (BCL2L1) gene, named circBCL2L1, which was related to the innate immune responses in teleost fish. Read More

Division of Hematology and Medical Oncology, Department of Internal Medicine, Michigan Medicine, Ann Arbor, Michigan, USA. Electronic address:

The cornerstone of management in patients with acute promyelocytic leukemia (APL) is early diagnosis and prompt initiation of treatment with an all-trans retinoic acid (ATRA)-based regimen. Identification of the t(15;17)(PML-RARA) chromosomal translocation through conventional cytogenetics fluorescence in-situ hybridization (FISH) or detection of the promyelocytic leukemia-retinoic acid receptor alpha (PML-RARα) fusion through RT-PCR represent the current standard of care for diagnosing APL.

Modulation of bioelectric cues in the evolution of flying fishes.

Curr Biol 2021 Sep 13. Epub 2021 Sep 13.

Department of Orthopaedic Research, Boston Children's Hospital, Boston, MA 02124, USA; Department of Genetics, Harvard Medical School, Boston, MA 02124, USA. Electronic address:

Changes to allometry, or the relative proportions of organs and tissues within organisms, is a common means for adaptive character change in evolution. However, little is understood about how relative size is specified during development and shaped during evolution. Here, through a phylogenomic analysis of genome-wide variation in 35 species of flying fishes and relatives, we identify genetic signatures in both coding and regulatory regions underlying the convergent evolution of increased paired fin size and aerial gliding behaviors.

Co-occurrence of contaminants in marine fish from the North East Atlantic Ocean: Implications for human risk assessment.

Environ Int 2021 Sep 13;157:106858. Epub 2021 Sep 13.

Institute of Marine Research, Bergen, Norway; University of Copenhagen, Copenhagen, Denmark.

Marine fish from the North East Atlantic Ocean (NEAO) are nutrient rich and considered a valuable economic resource. However, marine fish are also a major dietary source of several contaminants, including persistent organic pollutants (POPs) and heavy metals. Using one of the world's largest seafood datasets (n > 25,000 individuals), comprising 12 commercially important fish species collected during 2006-2019 in the NEAO, we assessed the co-occurrence of elements and POPs, and evaluated potential risks to human consumers.

Metagenomic insights into co-proliferation of Vibrio spp. and dinoflagellates Prorocentrum during a spring algal bloom in the coastal East China Sea.

Water Res 2021 Sep 3;204:117625. Epub 2021 Sep 3.

Department of Civil and Environmental Engineerimng, KAIST, Daejeon, 34141, Republic of Korea. Electronic address:

Coastal harmful algal blooms (HABs), commonly termed 'red tides', have severe undesirable consequences to the marine ecosystems and local fishery and tourism industries. Increase in nitrogen and/or phosphorus loading is often regarded as the major culprits of increasing frequency and intensity of the coastal HAB; however, fundamental understanding is lacking as to the causes and mechanism of bloom formation despite decades of intensive investigation. In this study, we interrogated the prokaryotic microbiomes of surface water samples collected at two neighboring segments of East China Sea that contrast greatly in terms of the intensity and frequency of Prorocentrum-dominated HAB.

Genome 2021 Sep 16. Epub 2021 Sep 16.

Kyoto University, 12918, Primate Research Institute, Inuyama, Japan;

The majority of DNA-based transposable elements comprise autonomous and nonautonomous copies, or only nonautonomous copies, where the autonomous copy contains an intact gene for a transposase protein and the nonautonomous copy does not. Even if autonomous copies coexist, they are generally less frequent. The element of medaka fish is one of the few elements for which a nonautonomous copy has not yet been found. Read More

Mutagenicity of carcinogenic heterocyclic amines in Salmonella typhimurium YG strains and transgenic rodents including gpt delta.

Genes Environ 2021 Sep 16;43(1):38. Epub 2021 Sep 16.

School of Pharmacy, Shujitsu University, 1-6-1 Nishigawara, Naka-ku, Okayama, 703-8516, Japan.

Chemical carcinogens to humans have been usually identified by epidemiological studies on the relationships between occupational or environmental exposure to the agents and specific cancer induction. In contrast, carcinogenic heterocyclic amines were identified under the principle that mutagens in bacterial in the Ames test are possible human carcinogens. In the 1970s to 1990s, more than 10 heterocyclic amines were isolated from pyrolysates of amino acids, proteins, meat or fish as mutagens in the Ames test, and they were demonstrated as carcinogens in rodents.

Department of Integrative Biology Ecology, Evolution, and Behavior Group Michigan State University East Lansing Michigan USA.

Although least chipmunks () are a widely distributed North American species of least concern, the southernmost population, (Peñasco least chipmunk), is imperiled and a candidate for federal listing as a subspecies. We conducted a phylogeographic analysis across the range to assess genomic differentiation and distinctiveness of the population. Additionally, we leveraged the historical component of sampling to conduct a temporal analysis of genetic diversity and also considered climate change effects on range persistence probability by projecting a species distribution model into the IPCC5 RCP 2.
