Core Tip

Core Tip: Hypoxia inducible factor 1α (HIF-1α) is a transcription factor that regulates oxygen homeostasis. Under hypoxic conditions, HIF-1α translocates to the nucleus and binds to β-subunits, resulting in transcription of target genes. In acute liver failure, HIF-1α contributes to early liver cell necrosis. The activation of Sirtuin1 (Sirt1) will result in a powerful antioxidant defense system. This study examined the influence of Sirt1-mediated pathways on HIF-1α expression in vivo and in vitro, explored the relationship between Sirt1 and HIF-1α, and further explored its potential mechanism.
