- W4214721856 abstract "Cervical cancer is the fourth most prevalent cancer in women worldwide, predominantly infected with human papillomavirus (HPV). The current chemo and radiotherapies are mostly futile due to acquired resistance to apoptosis and warrant new therapeutic approaches targeting potent non-apoptotic cell death pathways to eliminate cervical cancer cells. Induction of necroptosis by pharmaceutical interventions is emerging as a promising tool in multiple apoptotic resistant cancer cells. RETRA (REactivation of Transcriptional Reporter Activity) is a small molecule known to induce expression of p53 regulated genes in mutant (mt) p53 cells but, detailed mechanisms of its anticancer effects are poorly known. The present study investigated the potentials of RETRA as an anticancer agent and found that it induces necroptosis selectively in cervical cancer cells irrespective of p53 status through the phosphorylation of receptor-interacting protein kinase 1,3 (RIPK1, RIPK3) and mixed lineage kinase domain-like protein (MLKL) with no cytotoxic effects in normal human peripheral blood mononuclear cells (PBMCs). RETRA-treated cells also displayed necroptotic morphology of disintegrated plasma membranes with intact nuclei and also showed cell cycle arrest at the S phase with the upregulation of p21 and downregulation of cyclin-D3. Intriguingly, the combinatorial approach of using RETRA with Necrostain-1, a known inhibitor of necroptosis, reversed the effect of RETRA and rescued cell death. Moreover, induction of necroptosis by RETRA is associated with mitochondrial hyperpolarization and elevated ROS production. Collectively, these findings suggest that RETRA induces cell death via necroptosis with increased production of ROS, accentuating the therapeutic implication of RETRA in cervical cancer cells." @default.
