MDM2 inhibits p53 p53.free.fr
p53 Cellular Functions • Master control of cell cycle • It is a transcription factor. • Responds to cellular stresses by activating growth arrest or apoptosis
Mechanisms of Inhibition p53.free.fr
Phosphorylation activates p53 p53.free.fr
MDM2 cellular functions in normal cells • Cell survival • Cell cycle progression
MDM2’s ability to control p53 is essential during development p53.free.fr Jones et al
MDM2 is an oncogene • MDM2 overexpression blocks p53-mediated cell-cycle arrest and apoptosis.
Analysis of 3000 tumor samples shows that MDM2 is amplified in 7% of these tissues. Momand et al
MDM2 protein overexpression due to gene amplification Wikepedia.org
SNP309 polymorphism was detected in 232 (68%) of 343 familial breast cancer cases Wasielewski et all
No MDM2 gene amplification was observed in the presence of mutated p53 gene Pollock et al
