Covalent modification of the oncogene product Mdm2 by the ubiquitin-related protein SUMO1 protects it from ubiquitination and enhances its E3 ligase activity towards p53 in vitro. Disappearance of ...

This review also highlights the potential benefits of targeting both the MYCN and MDM2 oncogenes, providing preclinical evidence of the efficacy and safety of this approach. As a key survival ...

However, loss of p53 tumour-suppressor activity can also occur through amplification of MDM2. As MDM2 is a negative regulator of p53, this promotes p53 degradation and inhibits p53 tumour ...

A new review published in Genes & Diseases explores ... For instance, the study outlines the role of MDM2, an E3 ubiquitin ligase that targets p53, a well-known tumor suppressor protein.

Previous research revealed that nuclear factor of activated T cells 1 (NFAT1) is a novel regulator of the mouse double minute 2 homolog (MDM2) oncogene, which acts by directly binding to the MDM2 P2 ...
