Quercetin Enhances 5-fluorouracil Sensitivity by Regulating the Autophagic Flux and Inducing Drp-1 Mediated Mitochondrial Fragmentation in Colorectal Cancer Cells.

Our findings suggested that quercetin could induce protective autophagy and Drp-1-mediated mitochondrial fragmentation and enhance the sensitivity of CRC cells to conventional agent 5-FU, which not only suggests that quercetin may act as a chemotherapeutic adjuvant but also implies that the regulation of autophagic flux may be a potential therapeutic strategy for colorectal cancer.
