AVE 0991 attenuates oxidative stress and neuronal apoptosis via Mas/PKA/CREB/UCP-2 pathway after subarachnoid hemorrhage in rats
In conclusion, our data provides evidence that Mas activation with AVE reduces oxidative stress injury and neuronal apoptosis through Mas/PKA/p-CREB/UCP-2 pathway after SAH. Furthermore, our study indicates that Mas may be a novel therapeutic treatment target in early brain injury of SAH.Graphical abstract

VAOS, a novel vanadyl complexes of alginate saccharides, inducing apoptosis via activation of AKT-dependent ROS production in NSCLC.
In this study, VAOS exhibited effective inhibitory effects in NSCLC both in cultured cells and in a xenograft mouse model. VAOS was further identified to induce NSCLC cell apoptosis through activating protein kinase B (AKT) to elevate intracellular reactive oxygen species (ROS) levels by increasing in oxygen consumption and impairing the ROS-scavenging system. Neither silencing of PTP1B by siRNA nor transient overexpression of PTP1B had an effect on the AKT phosphorylation triggered by VAOS, indicating that PTP1B inhibition was not involved in VAOS-induced apoptosis. Through phosphorus colorimetric assay, we demonstrated t...

Plant mRNA decay: extended roles and potential determinants.
Abstract The decay of mRNA in plants is tightly controlled and shapes the transcriptome. The roles of this process are to digest RNA as well as to suppress exogenous and endogenous gene silencing by preventing siRNA generation. Recent evidence suggests that mRNA decay also regulates the accumulation of the putative 3' fragment-derived long non-coding RNAs (3'lncRNAs). The generation of siRNA or 3'lncRNA from a selective subset of mRNAs raises a fundamental question of how the mRNA decay machineries select and determine their substrate transcripts for distinctive decay destiny. Evidence for potential mRNA decay det...

Caffeic Acid Attenuates Rat Liver Injury after Transplantation Involving PDIA3-Dependent Regulation of NADPH Oxidase.
This study was undertaken to explore the effect of Caffeic acid (CA), a naturally occurring antioxidant, on I/R injury of grafted liver and the mechanisms involved. Male Sprague-Dawley rats underwent orthotopic liver transplantation (LT) in the absence or presence of CA administration. In vitro, HL7702 cells were subjected to hypoxia/reoxygenation. LT led to apparent hepatic I/R injury, manifested by deteriorated liver function, microcirculatory disturbance and increased apoptosis, along with increased PDIA3 expression and nicotinamide adenosine dinucleotide phosphate (NADPH) oxidase activity, and membrane translocation of...

Bub1 is not essential for the checkpoint response to unattached kinetochores in diploid human cells.
Abstract Error-free chromosome segregation during mitosis depends on a functional spindle assembly checkpoint (SAC). The SAC is a multi-component signalling system that is recruited to unattached or incorrectly attached kinetochores to catalyse the formation of a soluble inhibitor, known as the Mitotic Checkpoint Complex (MCC), which binds and inhibits the anaphase promoting complex (APC/C) [1]. We have previously proposed that two separable pathways, composed of KNL1-Bub3-Bub1 (KBB) and Rod-Zwilch-Zw10 (RZZ), recruit Mad1-Mad2 complexes to human kinetochores to activate the SAC [2]. Although Bub1 is absolutely re...

Transient acceleration of autophagic degradation by pharmacological Nrf2 activation is important for retinal pigment epithelium cell survival
In conclusion, we clarified the relationship between acceleration of the autophagy pathway and the cytoprotective effects of Nrf2 activation in RPE cells and zebrafish retina. These findings indicated that Nrf2 activation could be a promising therapeutic approach for non-exudative AMD by supporting RPE maintenance.Graphical abstract

AMPK/PGC1 α activation by melatonin attenuates acute doxorubicin cardiotoxicity via alleviating mitochondrial oxidative damage and apoptosis.
AMPK/PGC1α activation by melatonin attenuates acute doxorubicin cardiotoxicity via alleviating mitochondrial oxidative damage and apoptosis. Free Radic Biol Med. 2018 Aug 30;: Authors: Liu D, Ma Z, Di S, Yang Y, Yang J, Xu L, Reiter RJ, Qiao S, Yuan J Abstract Doxorubicin (DOX) is a highly effective anticancer anthracycline drug, but its side effects at the level of the heart has limited its widespread clinical application. Melatonin is a documented potent antioxidant, nontoxic and cardioprotective agent, and it is involved in maintaining mitochondrial homeostasis and function. The present study esta...
