Several flavonoids have been shown to inhibit the proliferation and migration of bladder cancer cells, including curcumin, which has been found to induce apoptosis and repress bladder tumor growth in vitro and in vivo [45], and myricetin, which has been shown to arrest T24 bladder cancer cells at G2/M through the downregulation of cyclin B1 and the cyclin-dependent kinase cell division control protein 2 homolog [46]. Here, CCNB1 is linked to urinary bladder cancer.
