... target proteins were identified, some of these proteins govern key signaling associated with gap junction, focal adhesion, actin cytoskeleton rearrangement. Cortactin, one of the biggest changed phospho-protein, is a novel oxidized ATM-dependent target in response to hypoxia. Mechanically, we reveal...

... the post-infarcted heart appears to benefit from systemic hypoxia. With this systematic review and meta-analysis, we aimed to discover whether systemic hypoxia is beneficial or detrimental to the infarcted myocardium. Methods: We conducted an electronic search of the PubMed, EMBASE, and Web of Science...

... acute myocardial infarction. Hypoxia and oxidative stress major roles in the pathophysiology of MVO. Pim1 serves an important protective role in the ischemic myocardium, but the underlying mechanisms remain poorly defined. Autophagy in early hypoxia or during moderate oxidative stress has been...

... hypoxia and up-regulated Sirt1 expression in EndoC-βH1 cells. Accordingly, H-1-2 enhanced glucose-stimulation insulin secretion and improved blood glucose and lipid profiles in T2DM cells, and elevated the glucose and insulin tolerance simultaneously. Furthermore, we demonstrated that H-1-2 alleviated...

...-regulated. Hypoxia can induce the expression of miR-146a by stimulating its promoter. In addition, we demonstrated that miR-146a promoted and CADM2 inhibited proliferation, migration, and invasion of ccRCC cells. The 3’ untranslated region (UTR) luciferase reporter assay identified that miR-146a targeted...

... of excitatory transmitter release, and attenuation of disrupted neuronal transmission. During prolonged hypoxia/ischemia, however, DOR neuroprotection involves a variety of signaling pathways. More recently, our data suggest that DOR may display its neuroprotective role via the BDNF-TrkB pathway. This review...

... to the protein phosphatase 2C family, has a role in cell survival and apoptosis. Hypoxia-inducible factor 1α (HIF-1α) is the key transcription factor in the response to oxygen deficiency in mammals. Direct phosphorylation and dephosphorylation of HIF-1α affect its function. The present study investigated...

... ischemic injury at the graft site are not well known. In this study, we aimed to determine if c-Met-activated mesenchymal stem cells (MSCs) pre-exposed to hypoxia promote therapeutic efficacy when transplanted to ischemic models, and whether c-Met interacts with cellular prion protein (PrP C ) present...

...Qianqian Shi; Jian Shi; Fengbao Luo; Guanglai Song; Xiaozhou He; Ying Xia Background/Aims: Mitogen-activated protein kinases (MAPKs) are involved in the cellular response to hypoxia and their dysregulation may contribute to the progression and pathology of diverse human renal diseases. Recent...

...Adolf M. Sandbichler; Bianca Jansen; Bettina A. Peer; Monika Paulitsch; Bernd Pelster; Margit Egg Background/Aims: Reduced oxygen availability, hypoxia, is frequently encountered by organisms, tissues and cells, in aquatic environments as well as in high altitude or under pathological conditions...

...Irene Filippi; Ilaria Saltarella; Carlo Aldinucci; Fabio Carraro; Roberto Ria; Angelo Vacca; Antonella Naldini Background/Aims: Hypoxia is a powerful stimulator of angiogenesis under physiological as well as pathological conditions. Normal endothelial cells (EC), such as human umbilical vein EC...

...–mesenchymal transition (EMT) was also observed after IL-11 incubation. Furthermore, IL-11 activated AKT and STAT3 in our experimental models. In addition, we observed that hypoxia induced IL-11 expression in NSCLC cells. Deferoxamine (DFX) or dimethyloxalylglycine (DMOG) induced hypoxia-inducible factor 1...

.... Methods: We analysed TPM2 expression and its correlation with the clinicopathological features in breast cancer. Then, we examined the influence of hypoxia on TPM2 expression and methylation status using bisulfite sequencing PCR. Furthermore, we performed TPM2-mediated migration and invasion assays...

...Zhankui Yan; Daifei Shen; Jilin Liao; Yanmei Zhang; Yicun Chen; Ganggang Shi; Fenfei Gao Background/Aims: Hypoxia modulation of transforming growth factor (TGF)- β-induced signaling during myofibroblast transformation is dependent on the specific cell type. The purpose of this study was to explore...

... (DOR) is protective against hypoxic/ischemic injury, we asked if pharmacological activation of DOR can alter hypoxic events by regulating miRNA expression in the liver. As the first step, the present work aimed at testing the effect of DOR activation on hepatic miRNA expression in hypoxia. Methods...

...) and invasion of cancer cells. However, the underlying molecular mechanisms have not fully elucidated. Methods: HCC cells were cultured under controlled hypoxia conditions or normoxic conditions. Transwell assays were used to examine the migration and invasion capacity. HIF-1α siRNA, cyclopamine (a SMO...

... HPH protection and the underlying mechanisms. Methods: Rats were exposed to 10% oxygen for three weeks to induce HPH. After hypoxia, the mean pulmonary arterial pressure (mPAP) and the right ventricular pressure (RVP) were measured. Cell viability was monitored using the Cell Counting Kit-8 (CCK-8...

... caused by tissue damage. However, unlike other injuries, RILI received limited therapeutic effects from implanted MSCs due to local hypoxia and extensive reactive oxygen species (ROS) in irradiated lungs. Since the poor survival of MSCs is primarily due to hypoxia and ROS generation, we hypothesize...
