Abstract:
Drug resistance remains a significant challenge in cancer therapy, often resulting in treatment failure, tumor progression, and metastasis. The underlying resistance mechanisms-including genetic mutations, epigenetic alterations, and modifications in drug efflux pathways-are complex and not yet fully understood. This review explores the application of CRISPR-Cas gene editing technology in understanding and overcoming drug resistance in cancer. It focuses on how CRISPR can identify and target resistance-associated genes to restore drug sensitivity. CRISPR-based approaches enable precise genetic modifications that offer new insights into the molecular basis of drug resistance. The technology has shown promise in dissecting resistance mechanisms and developing targeted therapeutic strategies. Nevertheless, key limitations such as inefficient delivery systems, off-target effects, and limited specificity hinder clinical translation. Current efforts focus on improving guide RNA design, creating more effective delivery vectors, and integrating CRISPR with existing treatments. CRISPR-Cas technology holds significant potential to address drug resistance in cancer by enabling targeted genetic interventions. Continued advancements are required to enhance its safety, specificity, and delivery, paving the way for its integration into future clinical applications.
