Ubiquitous Induction of p53 in Tumor Cells by Antisense Inhibition of MDM2 Expression

The MDM2 oncogene functions as a negative feedback regulator of the p53 tumor suppressor. Abnormal expression of MDM2 in tumors may attenuate the p53-mediated growth arrest and apoptosis response, resulting in in...

Activation of p53 by roscovitine-mediated suppression of MDM2 expression

The p53 tumor suppressor is regulated by the MDM2 oncoprotein. Overexpression of MDM2 maintains p53 at low levels and contributes to the functional inactivation of p53 in a subset of tumors. We found that trea...
