The other study confirmed tumor anti-angiogenesis effects of kaempferol and added the induction effects of this flavonoid compound on G2/M cell cycle arrest through the Chk2/Cdc25C/Cdc2 and Chk2/p21/Cdc2 pathways in A2780/CP70 ovarian cancer cells [106]. The gene discussed is CHEK2; the disease is ovarian carcinoma.
