WebHIF-1 is a transcription factor that contains two subunits, HIF-1α and HIF-1β. Under appropriate conditions, these two proteins heterodimerize in the nucleus and bind to promoter regions of a plethora of genes involved in angiogenesis, metabolic adaptation to hypoxia, resistance to oxidative stress and increased invasive properties ( 65 ). Web15 de jan. de 2009 · The oxidative stress in response to hypoxia exposure was evaluated by analyzing blood oxidation markers. Mean results of AOPP, 8-OHdG, and FRAP at …

Web29 de abr. de 2024 · Together, these data suggest a mechanism linking iron toxicity via HIF-2α and vulnerability to oxidative stress. Protective persulfidation via H 2 S can rescue DMF and HIF-2α–induced cell death. Since metal catalyst oxidation is a central mechanism for DNA damage ( 51 ), we checked the expression of γH2AX, a sensitive marker of DNA … Web11 de fev. de 2024 · The expression of HIF-1α was subsequently investigated due to the observation that increased oxidative stress is associated with an increased HIF-1α stabilization and activation [39,40,42,45,61]. Hypoxia has been widely reported as the most powerful inductor of HIF-1α transcriptional activity [ 39 , 40 , 42 ]; however, in the present … WebHIF-2alpha knockdown mice were more susceptible to renal IRI, as indicated by elevated blood urea nitrogen levels and semiquantitative histologic analysis.
