Abstract Background: Anisodine hydrobromide (AT3), an anti-cholinergic agent, could be delivered to the brain across the blood-brain barrier and has been used clinically for the treatment of cerebral ischemia/reperfusion injury. Endothelial dysfunction can be caused by hypoxia/reoxygenation (H/R) via oxidative stress and metabolic alterations. The present study investigated whether AT3 regulates the production of nitric oxide (NO) and reactive oxygen species (ROS), and the HIF-1α pathway via regulation of muscarinic acetylcholine receptors (mAChRs) in brain microvascular endothelial cells after H/R exposure. Methods: Under H/R conditions, hCMEC/D3 cerebral microvascular endothelial cells were treated with AT3. Specific inhibitors of M2- and M4- mAChRs… More > Graphic Abstract

Abstract In this study, we used a meta-analysis method to evaluate the relationship between hypoxia-inducible factor-1α (HIF1α) 1772C/T gene polymorphism (rs 11549465) and renal cell carcinoma (RCC)/prostate cancer risk. We searched for relevant studies (before March 1, 2019) on Cochrane Library, Embase, and PubMed. Studies meeting the inclusion criteria were recruited into this meta-analysis. The outcome of dichotomous data was showed in the way of odds ratios (OR), and 95% confidence intervals (CI) were also counted. In this investigation, there was no association between HIF1α 1772C/T gene polymorphism and susceptibility to RCC in Caucasians, Asians as well as overall populations. In… More >
