WebIntroduction. TP53 is possibly the most frequently altered gene in human cancers (Kandoth et al., 2013).The encoded p53 protein is a powerful tumor suppressor, and its loss-of-function is associated with cancer development and progression (Levine, 2024).Intriguingly, the majority of TP53 mutations are missense, encoding full-length proteins (mutp53) that … WebMay 12, 2024 · The anti-ferroptosis function of FSP1 is independent of cellular glutathione levels, GPX4 activity, ACSL4 expression, and oxidizable fatty acid content. Thus, FSP1 does not interfere with … WebIn some cells, FSP1 compensates for loss of GPX4 activity, and both GPX4 and FSP1 must be inhibited simultaneously to induce oxytosis/ferroptosis. Live-cell imaging has been used to observe the morphological changes that cells undergo during oxytosis/ferroptosis. Initially the cell contracts and then begins to swell. curiman brokers group logo
