Alternative splicing of the vitamin D receptor modulates target gene expression and promotes ligand-independent functions.

Toxicol Appl Pharmacol 2018 Dec 12. Epub 2018 Dec 12.

Department of Environmental and Molecular Toxicology, Oregon State University, 1007 Agriculture & Life Sciences Building, Corvallis, OR 97331; USA; LS Pharma, 884 Park St., Lebanon, OR 97355; USA.

Alternative splicing modulates gene function by creating splice variants with alternate functions or non-coding RNA activity. Naturally occurring variants of nuclear receptor (NR) genes with dominant negative or gain-of-function phenotypes have been documented, but their cellular roles, regulation, and responsiveness to environmental stress or disease remain unevaluated. Informed by observations that class I androgen and estrogen receptor variants display ligand-independent signaling in human cancer tissues, we questioned whether the function of class II NRs, like the vitamin D receptor (VDR), would also respond to alternative splicing regulation.

Department of Food Safety, German Federal Institute for Risk Assessment, Max-Dohrn-Str. 8-10, 10589, Berlin, Germany.

Alternaria mycotoxins are secondary fungal metabolites which can contaminate food and feed. They are produced by Alternaria species with alternariol (AOH), alternariol monomethyl ether (AME), tenuazonic acid (TeA), and tentoxin (TEN) as the main representatives for Alternaria mycotoxins in food. Once passing the intestinal barrier, Alternaria toxins can reach the liver to exert yet uncharacterized molecular effects. Read More

Role of a cotton endoreduplication-related gene, GaTOP6B, in response to drought stress.

Planta 2018 Dec 14. Epub 2018 Dec 14.

Zhengzhou Research Base, State Key Laboratory of Cotton Biology, Zhengzhou University, Zhengzhou, 450001, Henan, People's Republic of China.

Main Conclusion: Cotton GaTOP6B is involved in cellular endoreduplication and a positive response to drought stress via promoting plant leaf and root growth. Drought is deemed as one of adverse conditions that could cause substantial reductions in crop yields worldwide. Since cotton exhibits a moderate-tolerant phenotype under water-deficit conditions, the plant could therefore be used to characterize potential new genes regulating drought tolerance in crop plants.

Cotyledons contribute to plant growth and hybrid vigor in Arabidopsis.

Planta 2018 Dec 14. Epub 2018 Dec 14.

Faculty of Science, University of Technology, Sydney, NSW, 2007, Australia.

Main Conclusion: In hybrids of Arabidopsis, cotyledons influence the amount and proportion of hybrid vigor in total plant growth. We found Arabidopsis cotyledons are essential for plant growth and in some hybrids for hybrid vigor. In hybrids between C24 and Landsberg erecta (Ler), biomass vigor (heterosis) occurs in the first few days after sowing (DAS), with hybrid cotyledons being larger than those of their parents.

Generation by somatic cell nuclear transfer of GGTA1 knockout pigs expressing soluble human TNFRI-Fc and human HO-1.

Transgenic Res 2018 Dec 14. Epub 2018 Dec 14.

Department of Theriogenology and Biotechnology, College of Veterinary Medicine, Seoul National University, 1 Gwanak-ro, Gwanak-gu, Seoul, 08826, Korea.

Herein, we successfully generated transgenic pigs expressing both soluble human tumor necrosis factor receptor I IgG-Fc (shTNFRI-Fc) and human hemagglutinin (HA)-tagged-human heme oxygenase-1 (hHO-1) without Gal epitope. Healthy cloned pigs were produced by somatic cell nuclear transfer (SCNT) using the genetically modified cells. The genetic disruption of the GGTA1 genes and absence of expression of BS-IB4 lectin in tail-derived fibroblast of the SCNT-generated piglets were successfully confirmed. Read More

Sex-specific differences in genotoxic and epigenetic effects of 1,3-butadiene among mouse tissues.

Arch Toxicol 2018 Dec 14. Epub 2018 Dec 14.

Department of Veterinary Integrative Biosciences, College of Veterinary Medicine and Biomedical Sciences, Texas A&M University, College Station, TX, USA.

Exposure to environmental chemicals has been shown to have an impact on the epigenome. One example is a known human carcinogen 1,3-butadiene which acts primarily by a genotoxic mechanism, but also disrupts the chromatin structure by altering patterns of cytosine DNA methylation and histone modifications. Sex-specific differences in 1,3-butadiene-induced genotoxicity and carcinogenicity are well established; however, it remains unknown whether 1,3-butadiene-associated epigenetic alterations are also sex dependent.
