Core Tip

Core Tip: Oxaliplatin resistance remains a major clinical challenge in colorectal cancer (CRC). This study underscores the critical role of the NAD+/SIRT1 axis in driving metabolic reprogramming that facilitates resistance. Oxaliplatin-induced DNA damage activates PARP, leading to NAD+ depletion and subsequent downregulation of SIRT1. This reduction in SIRT1 expression enhances glycolysis, marked by upregulation of PKM2 and LDHA. Notable, restoration of SIRT1 reverses resistance, while glycolysis inhibition sensitizes CRC cells to oxaliplatin. These findings suggest that targeting the NAD+/SIRT1 pathway, through SIRT1 agonists and glycolysis inhibitors, offers a promising metabolic strategy to overcome chemoresistance and improve therapeutic outcomes in CRC patients.
