Unique role for lncRNA HOTAIR in defining depot-specific gene expression patterns in human adipose-derived stem cells.

Genes Dev 2022 May 26. Epub 2022 May 26.

Division of Diabetes Endocrinology and Metabolism, Johns Hopkins University School of Medicine; Institute for Fundamental Biomedical Research, Johns Hopkins All Children's Hospital, St. Petersburg, Florida 33701, USA.

Accumulation of fat above the waist is an important risk factor in developing obesity-related comorbidities independently of BMI or total fat mass. Deciphering the gene regulatory programs of the adipose tissue precursor cells within upper body or abdominal (ABD) and lower body or gluteofemoral (GF) depots is important to understand their differential capacity for lipid accumulation, maturation, and disease risk. Previous studies identified the HOX transcript antisense intergenic RNA (HOTAIR) as a GF-specific lncRNA; however, its role in adipose tissue biology is still unclear. Read More

Sci Total Environ 2022 May 23:156210. Epub 2022 May 23.

Programa de Pós-Graduação em Ecologia, Laboratório de Ecologia de Produtores, Instituto de Ciências Biológicas, Universidade Federal do Pará, Av. Perimetral, 2651 - Terra Firme, Belém, PA, 66077-530, Brazil; Universidade Federal Rural da Amazônia, Instituto Socioambiental e dos Recursos Hídricos, Avenida Perimetral, 660778-30 Belém, PA, Brazil.

The evaluation of extinction risk has typically focused on individual species, although a shift to a focus on ecosystem functioning would appear to be an urgent priority for conservation planning, especially considering that a sixth mass extinction event has already begun. In the present study, we investigated how fish extinction driven by habitat loss may modify the functioning of freshwater Amazonian ecosystems. We sampled the fish and environmental conditions of 63 streams in the eastern Amazon and simulated extinction based on the vulnerability of the species to habitat loss, which is the principal threat to tropical biodiversity.

Mice heterozygous for a null mutation of Cpe show reduced expression of carboxypeptidase E mRNA and enzyme activity but normal physiology, behavior, and levels of neuropeptides.

Brain Res 2022 May 23:147951. Epub 2022 May 23.

Pharmacological Sciences, Icahn School of Medicine at Mount Sinai, NY, NY, 10029. Electronic address:

Carboxypeptidase E (CPE) is an essential enzyme that contributes to the biosynthesis of the vast majority of neuropeptides and peptide hormones. There are several reports claiming that small decreases in CPE activity cause physiological changes in animals and/or cultured cells, but these studies did not provide evidence that neuropeptide levels were affected by decreased CPE activity. In the present study, we tested if CPE is a rate-limiting enzyme in neuropeptide production using CpeNeo mice, which contain a neomycin cassette within the Cpe gene that eliminates enzyme expression.
