Web15 de jan. de 2024 · Hif-2ɑ up-regulation mediated by AMPK and sirtuin-1 improves autophagy and oxidative stress. In line with energy surplus, T2D and obesity suppressed the activation of both AMPK and sirtuin-1, which further down-regulated the hypoxia inducible factor-2ɑ (Hif-2ɑ). WebHypoxic HIF-1β-deficient Hepa-1c4 cells increased expression of PGC-1α, phospho-p38 MAPK, and PPARα, suggesting AMPK pathway activation to survive hypoxia. They had higher intracellular acetate, and secreted more H2O2, suggesting increased peroxisomal fatty acid β-oxidation.
