Web5 de abr. de 2001 · Hypoxia-inducible factor (HIF) is a transcriptional complex that plays a central role in the regulation of gene expression by oxygen. In oxygenated and iron replete cells, HIF-α subunits are rapidly destroyed by a mechanism that involves ubiquitylation by the von Hippel–Lindau tumor suppressor (pVHL) E3 ligase complex. Web14 de fev. de 2024 · Given the apparent association of HIF-1α expression with IDH1 mutation, we asked whether such mutation confers angiogenic properties on the chondrosarcoma JJ012 cells.

WebDuring TSC2 mutation, there is an increase in HIF-1, which often results in a high glucose consumption rate . Furthermore, mTOR controls fatty acid oxidation and provides substrates to generate energy through the TCA cycle and oxidative phosphorylation and meet the nutritional demands of cancer cells during glucose deficiency . Another ... WebThis mutation disrupts the function of the VHL protein, particularly its ability to target HIF-2α to be broken down. As a result, HIF accumulates in cells even when adequate oxygen is available. The presence of extra HIF leads to the production of red blood cells when no more are needed, which leads to an excess of these cells in the bloodstream.
