Advances in p73-targeting anti-tumor drugs / 中国药理学通报

The transcription factor p73 belongs to the p53 family of tumor suppressors,and can be transcribed into different isoforms with either pro-or anti-apoptotic(TAp73 and △Np73)functions.However,the tumor suppressor activity of TAp73 is inhibited through complex formation with inhibitory proteins(e.g.△Np73,mutant p53,MDM2 and iASPP).Therefore,it is a kind of tumor therapy strategy to reactivate TAp73 through targeting these inhibitors directly or release TAp73 from the complex by targeting their interaction.This review discusses the possible strategies of targeting p73 for its reactivation and the acting mechanism of related compounds.
