It is largely undetectable in cells or tissues grown under normoxic conditions. It is stabilized only at O2 concentrations below 5% and upon stabilization under hypoxic conditions HIF-1 translocates to the nucleus. Hypoxia can be induced with treatment using certain ...

WebAug 6, 2024 · Oxygen homeostasis disturbances play a critical role in the pathogenesis of acute kidney injury (AKI). The transcription factor hypoxia-inducible factor-1 (HIF-1) is a master regulator of adaptive responses to hypoxia. Aside from posttranslational hydroxylation, the mechanism of HIF-1 regulation in AKI remains largely unclear. In this … WebApr 11, 2024 · HIF-1α activates TMEM237 transcription in hypoxic HCC cells. We previously investigated hypoxia-induced transcripts in Hep3B cells using a microarray assay [].The microarray data (GSE155505) showed that TMEM237 was significantly upregulated in Hep3B cells under hypoxic conditions (Fig. 1a). Then, RT‒qPCR and Western blotting … small oil dispensing bottles
