Web4 de abr. de 2024 · Hypoxia upregulated transcription from all three alternative HIF-3alpha promoters. siRNA experiments showed that this induction is mediated specifically by HIF-1 and not by HIF-2. The findings shed light on a novel aspect of HIF-3alpha as a HIF-1 target gene and point to a possible role as a modulator of hypoxic gene induction. WebCotransfection of cells with an expression vector encoding a dominant negative form of HIF-1α inhibited the activation of reporter transcription in hypoxic cells in a dose-dependent manner. VEGF mRNA was not induced by hypoxia in mutant cells that do not express the HIF-1β (ARNT) subunit.
