Web6 de jan. de 2016 · PKM2 physically interacts with HIF-1α in the nuclei of hypoxic human cancer cells and promotes transactivation of HIF-1α target genes by enhancing the … Web5 de mai. de 2011 · PKM2 is a HIF-1 Target Gene. Previous studies demonstrated that hypoxia induces PKM mRNA expression (Semenza et al., 1994).To determine whether …
WebPKM2 is also a coactivator of HIF-1α where PKM2 hydroxylation activates HIF-1 α generating a positive feedback loop that results in its production [27]. The involvement of PKM2 in cancer anticipates the idea that a loss of PKM2 inhibits cancer development; however, removing PKM2 did not lead to inhibition of tumor metabolism [28] . WebThe JMJD5-PKM2 interaction resides at the intersubunit interface region of PKM2, which hinders PKM2 tetramerization and blocks pyruvate kinase activity. This interaction also …
