Hydrogen peroxide (H(2)O(2)) is an extremely reactive oxidoradical that is normally produced as a by-product of the mitochondrial activity and also under several metabolic stress conditions. Autophagy, a lysosomal degradation pathway, is triggered by oxidative stress as a defensive response. How autophagy and death pathways are coordinated in cells subjected to oxidative stress is still poorly ...
Purpose Ghrelin, a natural ligand for the growth hormone secretagogue receptor type 1a (GHSR-1a), may protect retinal neurons against glaucomatous injury. We therefore characterized the underlying mechanism of the ghrelin/GHSR-1a-mediated neuroprotection with a rat chronic intraocular hypertension (COH) model. Methods The rat COH model was produced by blocking episcleral veins. A combination ...
We examined the interaction between the multikinase inhibitor sorafenib and histone deacetylase inhibitors. Sorafenib and vorinostat synergized (sorafenib + vorinostat) to kill HCT116 and SW480 cells. In SW480 cells, sorafenib + vorinostat increased CD95 plasma membrane levels and promoted death-inducing signal complex (DISC) formation, and drug toxicity was blocked by knockdown of CD95 or over...
Critical role of autophagy regulator Beclin1 in endothelial cell inflammation and barrier disruption
Autophagy, type II nonapoptotic cell death, is characterized by the formation of double-membrane cytosolic vesicles, the recycling of damaged cytoplasmic content and the maintenance of genetic stability and cellular homeostasis, under conditions of nutrient starvation, hypoxia or other therapeutic stress. In the present study, we comprehensively discuss its indispensable role in the formation o...
