Webb9 apr. 2024 · “The results showed that FAM193A interferes with cellular factors that usually repress p53 function, the proteins MDM2 and MDM4, which are commonly overactive in cancers. We found that FAM193A can antagonize the MDM4 protein and thus unleash p53’s ability to stop cancer cell proliferation and survival. WebbNormally, wild-type p53 protein (wtp53) is either degraded or bound to a negative regulator and is inactive. When damage to DNA occurs within a cell, p53 protein is induced and causes cell cycle arrest. This gives cells a chance to repair, but if damage is too severe, cells undergo apoptosis and are rejected.
