Platinum-based drugs, such as cisplatin and oxaliplatin, are frontline chemotherapy for CRC, effective in both monotherapy and combination regimens. However, the clinical efficacy of these treatments is often undermined by the development of drug resistance, a significant obstacle in cancer therapy. In recent years, epigenetic alterations have been recognized as key players in the acquisition of resistance to platinum drugs. Targeting these dysregulated epigenetic mechanisms with small molecules represents a promising therapeutic strategy. This review explores the complex relationship between epigenetic changes and platinum resistance in CRC, highlighting current epigenetic therapies and their effectiveness in countering resistance mechanisms.

However, the role and mechanisms of RIPK1 on sunitinib sensitivity in renal cell carcinoma (RCC) remain elusive. In this study, we demonstrated that the O-linked β-N-acetylglucosamine modification (O-GlcNAcylation) of RIPK1 induces sunitinib resistance in RCC by inhibiting RDA.
