The testosterone metabolite 3α-androstanediol inhibits oxidative stress-induced ERK phosphorylation and neurotoxicity in SH-SY5Y cells through an MKP3/DUSP6-dependent mechanism.

Neurosci Lett 2018 Dec 12. Epub 2018 Dec 12.

Department of Biomedical Sciences, Ontario Veterinary College, University of Guelph, 50 Stone Road East, Guelph, Ontario, N1G 2W1, Canada. Electronic address:

Testosterone exerts neuroprotective effects on the brain, but the mechanisms by which these effects are exerted appear to be different in males and females. While in females they involve local conversion to estradiol, in males they may be androgen receptor-dependent, or mediated through metabolism to neurosteroids such as 5α-androstane-3α,17β-diol (3α-diol), which acts through different mechanisms than testosterone itself. Recently, we demonstrated that 3α-diol can protect neurons and neuronal-like cells against oxidative stress-induced neurotoxicity associated with prolonged phosphorylation of the extracellular signal-regulated kinase (ERK).

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.

Cell-Based Model of the Generation and Maintenance of the Shape and Structure of the Multilayered Shoot Apical Meristem of Arabidopsis thaliana.

Bull Math Biol 2018 Dec 14. Epub 2018 Dec 14.

Department of Mathematics, University of California, Riverside, USA.

One of the central problems in animal and plant developmental biology is deciphering how chemical and mechanical signals interact within a tissue to produce organs of defined size, shape, and function. Cell walls in plants impose a unique constraint on cell expansion since cells are under turgor pressure and do not move relative to one another. Cell wall extensibility and constantly changing distribution of stress on the wall are mechanical properties that vary between individual cells and contribute to rates of expansion and orientation of cell division.

Salinity is one of the most important abiotic stresses, which affects the yield and quality of banana (Musa paradisiaca). To understand the salinity tolerance mechanisms of banana, the iTRAQ technique is employed to reveal the proteomic response of Brazil banana under different durations of 60 mmol/L NaCl stress. We have identified 77 DEPs and classified them into nine functional categories, compared with control (0 mmol/L NaCl treatment). 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.

Time-course study of high fat diet induced alterations in spatial memory, hippocampal JNK, P38, ERK and Akt activity.

Metab Brain Dis 2018 Dec 14. Epub 2018 Dec 14.

Department of Physiology, Faculty of Medicine, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Consumption of high fat diet (HFD) is a health concern in modern societies, which participate in wide range of diseases. One underlying mechanism in the HFD mediated pathologies is disruption of insulin signaling activity. It is believed that HFD activates several stress signaling molecules such as MAPKs signaling pathway and these molecules participate in harmful effects in different cell populations including hippocampal cells.

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
