Web26 de jun. de 2024 · It inhibits PKM2 transfer out of the nucleus and inhibits tumor growth. Proline hydroxylation of PKM2 at 403 and 408 by the PHD3 enzyme favors the interaction of PKM2 with the HIF-1α transcription complex, which results in recruitment of P300-acetyltransferase to facilitate the transactivation of HIF target genes. 3. WebM1/M2 macrophage polarization plays a pivotal role in the development of acute lung injury (ALI). The hypoxia-inducible factor-1α/pyruvate kinase M2 (HIF-1α/PKM2) axis, which …
WebNational Center for Biotechnology Information 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] .
