Web25 de out. de 2024 · The interaction of PKM2 and HIF-1α forms a PKM2-HIF-1α complex, binding to the IL-1β promoter inducing the secretion of proinflammatory cytokines and triggers inflammatory response. Secondly, PKM2 controls the activation and effector functions of CD4+ T cell by modulating the functions of HIF-1α, mTORC1, and Myc and …

Web26 de fev. de 2024 · Mechanistically, HIFAL recruits prolyl hydroxylase 3 (PHD3) to pyruvate kinase 2 (PKM2) to induce its prolyl hydroxylation and introduces the PKM2/PHD3 … 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] . Web14 de set. de 2024 · Activation of HIF-1α occurs due to protein stabilization [] by inhibition of the prolyl hydroxylase family (PHD1-3), which hydroxylates specific prolyl residues in the oxygen-dependent degradation (ODD) domain of HIF-1α to enhance its degradation [15, 16].PHD3 also hydroxylates specific proline residues on PKM2 in mild (1% O2) but not … iot device provisioning
