In nasopharyngeal carcinoma HK1 and CNE2 cells, quercetin exhibits synergic effects regarding cell cycle arrest and apoptosis, wherein it regulates pro-apoptotic mediators (Bad, caspase-3, and caspase-7) to induce cytotoxic effects while concurrently arresting cells in G0/G1 or G2/M phases (Pastushenko and Blanpain, 2019)
