PCNA protein expression in different treatment groups. A significant increase in PCNA protein expression was noted following concomitant treatment of estrogen and progesterone with 100 mg/kg/day quercetin. Meanwhile, significantly lower expression of PCNA protein was noted following co-administration of 10 mg/kg/day quercetin with estrogen plus progesterone. C = vehicle, E+P = estrogen plus progesterone, (E+P) +10Q = estrogen plus progesterone with 10 mg/kg/day quercetin, (E+P)+100Q = estrogen plus progesterone with 100 mg/kg/day quercetin. *P < 0.05 as compared to C. †P < 0.05 as compared to E+P.
