Investigation of the anti-cancer properties of natural products and synthetic analogues with NQO2 inhibiting potential
TL;DR: The ping-pong mechanism of NQO2 in oxidative stress and cellular growth is studied, which results in down-regulation in breast cancer and inflammation and oxidative stress in women.
Journal ArticleDOI
Dementia and cancer: a review of the literature and current practice
TL;DR: Genetic mechanisms could underpin this inverse relationship between dementia and cancer and are outlined, but underdiagnosis must also be taken into account.

Interleukin 6 Knockout Inhibits Aging-Related Accumulation of p53 in the Mouse Myocardium.

TL;DR: It is concluded that lack of IL6 attenuates expression of p53 protein in the hearts of young mice and diminishes its accumulation with aging by post-transcriptional mechanisms; however, this is not related to altered phenotype of aging heart.

The Undervalued Avenue to Reinstate Tumor Suppressor Functionality of the p53 Protein Family for Improved Cancer Therapy-Drug Repurposing.
TL;DR: The most advanced strategies to reactivate p53 and p73 are outlined and drug repurposing approaches for the efficient reinstatement of the p53 proteins for cancer therapy are described.

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.

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.
