Web28 de set. de 2024 · Abstract. The major adaptive response to hypoxia involves hypoxia-inducible factor HIF-1α which is regulated by von Hippel Lindau (VHL) E3 ligase. We previously observed a stabilization of HIF-1α by cyclin-dependent kinases CDK1 and CDK4/6 that is independent of VHL, hypoxia or p53, and found that CDK4/6 inhibitors …

Based on the above evidence, it can be concluded that ferroptosis can generate and release lipid metabolites as inflammatory mediators, … Web25 de out. de 2024 · The interaction of PKM2 and HIF-1α forms a PKM2-HIF-1α complex, binding to the IL-1β promoter inducing the secretion of proinflammatory cytokines and triggers inflammatory response. Secondly, PKM2 controls the activation and effector functions of CD4+ T cell by modulating the functions of HIF-1α, mTORC1, and Myc and …
WebMechanistically, HIF-1α directly bound to the GPX4 gene promoter region and promoted GPX4 transcription. AKT inhibitor MK-2206 and HIF-1α inhibitor PX-478 could signicantly reverse the effect. Besides, under normoxia, PX-478 could induce a higher lipid peroxidation level by decreasing GPX4 expression in U87 and U251 cells but cannot induced ...
