The objective of this study was to assess the effect of antiandrogen on the activation of mutated androgen receptor (AR) and its signaling pathway in prostate cancer. We transfected the AR gene with a point mutation at codon 741 (tryptophan to leucine; W741L) into human androgen-independent prostate cancer PC3 cells lacking the expression of AR, and established PC3 cells overexpressing mutant t...
Angiotensin II (Ang II) has been shown to function as a key role in neovascularization of hepatocellular carcinoma (HCC), but little is known its underlying mechanisms. The aim of this study was to explore the role of Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway in Ang II-induced HCC angiogenic factors production. Herein, we found that Ang II upregu...
Previous studies have shown that the JAK2/STAT3 signaling pathway plays a regulatory role in cellular oxidative stress injury (OSI). In this study, we explored the role of the JAK2/STAT3 signaling pathway in hydrogen peroxide (H2O2)-induced OSI and the protective effect of melatonin against (H2O2)-induced injury in human umbilical vein endothelial cells (HUVECs). AG490 (a specific inhibitor of ...
Sensory axons in the adult spinal cord do not regenerate after injury. This is essentially because of inhibitory components in the damaged CNS, such as myelin-associated inhibitors and the glial scar. However, if the sciatic nerve is axotomized before injury of the dorsal column, injured axons can regenerate a short distance in the spinal cord. Here, we show that sciatic nerve transection resul...
To explore the involved mechanisms and possible treatments of ambient PM2.5 exposure-induced lung inflammation, this work studied activity luteolin, a natural flavonoid which widely presents in many plant species, murine alveolar macrophage MH S cells exposed to PM2.5. Results showed induced an inflammatory response, as evidenced by significantly increased TNF-α, IL-6, MCP-1 Rantes levels. iNOS...
RATIONALE Reduction of myocardial infarct size by remote ischemic preconditioning (RIPC), that is, cycles of ischemia/reperfusion in an organ remote from the heart before sustained myocardial ischemia/reperfusion, was confirmed in all species so far, including humans. OBJECTIVE To identify myocardial signal transduction of cardioprotection by RIPC. METHODS AND RESULTS Anesthetized pigs were...
