Estrogens Counteract Platinum-Chemosensitivity by Modifying the Subcellular Localization of MDM4.

Estrogen activity towards cancer-related pathways can impact therapeutic intervention. Recent omics data suggest possible crosstalk between estrogens/gender and MDM4, a key regulator of p53. Since MDM4 can either promote cell transformation or enhance DNA damage-sensitivity, we analysed in vivo impact of estrogens on both MDM4 activities.

Peptides and peptidomimetics in the p53/MDM2/MDM4 circuitry - a patent review.

Restoration of the p53 tumor suppressor function is an attractive anticancer strategy. Despite the development of several therapeutics targeting the two main p53 negative regulators, MDM2 and MDM4, no one has yet reached clinical application. In the past, several efforts have been employed to develop more specific and efficient compounds that can improve and/or overcome some of the features related to small molecule compounds (SMC).
