Journal ArticleDOI
The Many Faces of MDM2 Binding Partners
TL;DR: Mdm2 is an essential regulator of the p53 tumor suppressor and has E3-ligase independent functions and p53-independent functions that have important implications for genome stability and cancer.
Journal ArticleDOI
Dysregulation of Glucose Metabolism by Oncogenes and Tumor Suppressors in Cancer Cells
Casterland Marbaniang,Lakhan Kma +1 more
TL;DR: This review summarizes the roles of tumor suppressors and oncogenes and their products that provide metabolic advantages to cancer cells which in turn leads to the establishment of the “Warburg effect” and ultimately leads to cancer progression.
Journal ArticleDOI
Hypoxia downregulates p53 but induces apoptosis and enhances expression of BAD in cultures of human syncytiotrophoblasts
TL;DR: It is speculated that downregulation of p53 activity in response to hypoxia reduces or eliminates the apoptosis transduced by the p53 pathway in syncytiotrophoblasts, thereby limiting cell death and maintaining the integrity of this critical villous component.
Journal ArticleDOI
Reviving the guardian of the genome: Small molecule activators of p53.
TL;DR: This essay offers readers with a grand review on this progress with updated information about small molecule activators of p53 either still at bench work or in clinical trials.
Journal ArticleDOI
Regulation of tissue- and stimulus-specific cell fate decisions by p53 in vivo.
TL;DR: This review summarizes the current status of knowledge regarding p53‐mediated stress and tissue‐dependent cell fate decisions in mouse models and human tumours.

WAF1, a potential mediator of p53 tumor suppression
Wafik S. El-Deiry,Takashi Tokino,Victor E. Velculescu,Daniel B. Levy,Ramon Parsons,Jeffrey M. Trent,D Lin,W. Edward Mercer,Kenneth W. Kinzler,Bert Vogelstein +9 more
TL;DR: A gene is identified, named WAF1, whose induction was associated with wild-type but not mutant p53 gene expression in a human brain tumor cell line and that could be an important mediator of p53-dependent tumor growth suppression.

In vivo activation of the p53 pathway by small-molecule antagonists of MDM2.
Lyubomir T. Vassilev,Binh Thanh Vu,Bradford Graves,Daisy Carvajal,Frank John Podlaski,Zoran Filipovic,Norman Kong,Ursula Kammlott,Christine Lukacs,Christian Klein,Nader Fotouhi,Liu Emily Aijun +11 more
TL;DR: In this article, the authors identify potent and selective small-molecule antagonists of MDM2 and confirm their mode of action through the crystal structures of complexes, leading to cell cycle arrest, apoptosis, and growth inhibition of human tumor xenografts.
Journal ArticleDOI
Mdm2 promotes the rapid degradation of p53
TL;DR: It is proposed that the Mdm2-promoted degradation of p53 provides a new mechanism to ensure effective termination of the p53 signal.
Journal ArticleDOI
Regulation of p53 stability by Mdm2
TL;DR: It is shown that interaction with Mdm2 can also result in a large reduction in p53 protein levels through enhanced proteasome-dependent degradation, which may contribute to the maintenance of low p53 concentrations in normal cells.
Journal ArticleDOI
Oncoprotein MDM2 is a ubiquitin ligase E3 for tumor suppressor p53
TL;DR: The data suggest that the MDM2 protein, which is induced by p53, functions as a ubiquitin ligase, E3, in human papillomavirus‐uninfected cells which do not have E6 protein.
