P53 effects
WebAn important effect of p53 mutation is often the production of a more stable p53 mutant protein with concomitant higher expression. Consequently, mutant p53 is regarded as a … WebOr, if the damage is too severe, p53 initiates the process of programmed cell death, or apoptosis, which directs the cell to commit suicide, permanently removing the damage.

WebFeb 13, 2004 · In most cases, p53-induced apoptosis proceeds through mitochondrial release of cytochrome c, which leads to caspase activation ( 6 ). Although most of the effects of p53 are ascribed to its function as a transcription factor, reports have suggested that the protein can also induce apoptosis independently of new protein synthesis ( 7 – 10 ).
Webp53 activates various responses, including cell-cycle arrest and apoptosis. Each of these appears to contribute to tumour suppression. p53 responds to both acute stress, such as … p53 plays a role in regulation or progression through the cell cycle, apoptosis, and genomic stability by means of several mechanisms: • It can activate DNA repair proteins when DNA has sustained damage. Thus, it may be an important factor in aging. • It can arrest growth by holding the cell cycle at the G1/S regulation point on DNA damage recognition—if it holds the cell her…
WebMdm2 promotes the ubiquitination and degradation of p53, while Mdm2-p60 can bind to p53 and reduce the Mdm2-induced p53 ubiquitination to improve its stability. ... Altogether USP2a is oxygen sensitive, oxidized USP2a exerts apoptotic effects through the Mdm2-p60-p53 axis, which provides an experimental basis for regulating p53 apoptotic ... WebPeople who inherit only one functional copy of p53 will most likely develop tumors in early adulthood, a disease known as Li-Fraumeni syndrome. p53 can also be damaged in cells by mutagens (chemicals, radiation or viruses), increasing the likelihood that the cell will begin uncontrolled division.
WebAn important effect of p53 mutation is often the production of a more stable p53 mutant protein with concomitant higher expression. Consequently, mutant p53 is regarded as a “foreign” antigen by the immune system and triggers an immune response that results in the production of auto-anti-p53 antibodies.
WebSep 1, 1998 · The effects of MEKK1 on p53 are likely to be mediated by JNK since (i) JNKK is capable of enhancing these effects with regard to p53 stability and transcriptional activities; (ii) a catalytic inactive form of JNKK attenuates MEKK1’s effects; (iii) p53 that is mutated within or deleted of the p7 domain, which was mapped as a JNK-binding site ... cheristerfield thangkhiewWebFeb 9, 2024 · We find that radiosensitive tissues show prolonged p53 signaling after radiation, while more resistant tissues show transient p53 activation.
