Increased Dynamin ‐Related Protein 1‐Dependent Mitochondrial Fission Contributes to High‐Fat Diet‐Induced Cardiac Dysfunction and Insulin Resistance by Elevating Tafazzin in Mouse Hearts
ConclusionIn high ‐fat diet‐fed mouse hearts, increased tafazzin contributes to insulin resistance via mediating Drp‐1 translocation to the mitochondria, and a small non‐coding RNA, miR‐125b‐5p, at least partially regulates this signalling pathway and alleviates insulin resistance.This article is protected by copyright.

Oxymatrine Inhibits Homocysteine-Mediated Autophagy via MIF/mTOR Signaling in Human Umbilical Vein Endothelial Cells
Conclusions: These results suggest that Hcy can evokeautophagy-activated HUVEC apoptosis/death via a MIF/mTOR signaling pathway, which can be reversed by OMT. Our results provide a new insight into a functional role of OMT in the prevention of Hcy-induced HUVEC injury and death.Cell Physiol Biochem 2018;45:1893 –1903

Vitamin A Deficiency Induces Autistic ‐Like Behaviors in Rats by Regulating the RARβ‐CD38‐Oxytocin Axis in the Hypothalamus
Conclusions: Gestational VAD might be a risk factor for autistic‐like behaviors due to the RARβ signal suppression of CD38 expression in the hypothalamus of the offspring, which improved with VAS during the early‐life period. The nutritional status during pregnancy and the early‐life period is important in rats.This article is protected by copyright. All rights reserved

Regulation of hepatic lipid deposition by phospholipid in large yellow croaker.
Abstract Dietary phospholipid (PL) supplementation has been shown to reduce lipid accumulation in the tissues of farmed fish; however, the mechanisms underlying this effect are largely unknown. Thus, the present study was conducted to evaluate the potential impacts of PL on hepatic lipid metabolism both in vivo and in vitro. For in vivo study, four experimental diets - low lipid and low PL diet, as control diet (LL-LP diet, containing 12 % lipid and 1·5 % PL), low-lipid and high-PL diet (containing 12 % lipid and 8 % PL), high-lipid and low-PL diet (HL-LP diet, containing 20 % lipid and 1·5 % PL) and high-lipid ...

The role of a single gene encoding the Single von Willebrand factor C-domain protein (SVC) in bumblebee immunity extends beyond antiviral defense.
Abstract The Single von Willebrand factor C-domain proteins (SVCs) are a group of short proteins mainly found in arthropods. They are proposed to be responsive in relation to environmental challenges including the nutritional status, bacterial and viral infections. The SVC protein Vago acts as a cross-talk molecule between the small interfering RNA (siRNA) pathway and the Jak/STAT pathway upon viral infection in Drosophila melanogaster and Culex mosquito cells. Unlike flies and mosquitoes that possess diverse SVCs, most bee species only have one of which the function remains unclear. Here we investigated whether t...

Co-Administration of Myostatin-Targeting siRNA and ActRIIB-Fc Fusion Protein Increases Masseter Muscle Mass and Fiber Size.
Authors: Bayarsaikhan O, Kawai N, Mori H, Kinouchi N, Nikawa T, Tanaka E Abstract Myostatin, a member of the TGF-β superfamily, is a negative regulator of skeletal muscle cell growth and differentiation, and binds with high affinity to the activin type IIB receptor (ActRIIB). The soluble ligand-binding domain of ActRIIB fused to the Fc domain of IgG (ActRIIB-Fc) potently binds and inhibits TGF-β family members in muscle, leading to rapid and marked muscle growth. The present study was designed to assess the effectiveness of the co-delivery of myostatin-targeting siRNA (Mstn-siRNA) and ActRIIB-Fc into skeletal mus...

HIF-1 α coordinates epigenetic activation of SIAH1 in hepatocytes in response to nutritional stress
We report that in response to nutritional stress, SIAH1 expression was up-regulated in the liver in mice and in cultured hepatocytes. In the meantime, HIF-1α started to occupy the SIAH1 promoter. Depletion of HIF-1α with siRNA or inhibition of HIF-1α with chetomin abrogated the induction of SIAH1 expression. HIF-1α knockdown or inhibition paralleled epigenetic alterations surrounding the SIAH1 promoter characterized by the loss of acetylated histone H3 and trimethylated H3K4 as well as the acquisition of dimethylated H3K9. Further analyses revealed that HIF-1α interacted with and recruited the histone demethylase KDM3...
