Mdm2-mediated ubiquitylation: p53 and beyond

Marine, J-C, Lozano, G·2010·Cell Death & Differentiation

Abstract

The really interesting genes (RING)-finger-containing oncoprotein, Mdm2, is a promising drug target for cancer therapy. A key Mdm2 function is to promote ubiquitylation and proteasomal-dependent degradation of the tumor suppressor protein p53. Recent reports provide novel important insights into Mdm2-mediated regulation of p53 and how the physical and functional interactions between these two proteins are regulated. Moreover, a p53-independent role of Mdm2 has recently been confirmed by genetic data. These advances and their potential implications for the development of new cancer therapeutic strategies form the focus of this review.

  • The polyploidy observed in Mdm2 transgenic cells is likely due at least in part to inhibition of p53 by Mdm2.

    “Since Mdm2 negatively regulates p53 (Marine and Lozano, 2010), and p53 inhibits the development of tetraploidy (Fujiwara et al., 2005, Ganem et al., 2007, Storchova and Kuffer, 2008, Thompson et al., 2010, Vitale et al., 2010), the polyploidy we observed in Mdm2 transgenic cells is likely due at least in part to inhibition of p53 by Mdm2.”
  • Mdm2 negatively regulates both p53 and mediators of ATM activation, the Mre11/Rad50/Nbs1 DNA repair complex.

    “Mdm2 negatively regulates both p53 and mediators of ATM activation, the Mre11/Rad50/Nbs1 DNA repair complex (Alt et al., 2005, Bouska et al., 2008, Marine and Lozano, 2010).”
  • MDM2 overexpression at supraphysiological levels is toxic to many normal cells, suggesting it may have other cellular targets.

    “This is probably because MDM2 overexpression at supraphysiological levels is toxic to many normal cells, suggesting that it may have other cellular targets61.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
