Therapeutic potential of p53 reactivation in prostate cancer: Strategies and opportunities
European Journal of Pharmacology(2022)
Abstract
Metastatic prostate cancer (mCaP) remains one of the leading causes of cancer-related death in men worldwide. Androgen receptor (AR) drives the progression of most of the mCaP, and hence the androgen deprivation therapy (ADT) is the first-line treatment of choice for mCaP. Although the responses of ADT and next-generation AR inhibitors initially improve the disease burden, the responses of this combinatorial drug therapy varied widely due to molecular alteration in mCaP patients. In addition to the altered AR signaling, loss of potent tumor-suppressor protein p53 exhibits poor outcomes. p53 influences cell plasticity and is frequently lost in more aggressive prostate cancer (CaP) with neuroendocrine differentiation. Loss of p53 antagonizes the effect of AR inhibitors and enhances the proliferation rate of CaP cells. Considering the important role of p53 inactivation in cancer development, restoration of wild-type p53 function by p53-reactivating compounds developed with different approaches, seems to be an attractive therapeutic strategy for prostate cancer therapy. In this review, we discuss the therapeutic potential of these compounds with a particular focus on the pharmacological rescue of p53 in mCaP. In addition, we also highlight the challenges and new opportunities of p53-targeted therapy for the future.
