Bovine embryonic development is closely associated with mitochondrial biogenesis, which is regulated by the sirtuin 1 (SIRT1). Resveratrol, which is a type of natural phenol produced by several plants and used as a dietary supplement, is the activator of SIRT1. Although it has been reported that resveratrol increased SIRT1 level in in vitro bovine blastocysts, there are no in vivo reports on the change in the plasma SIRT1 level in cows. Therefore, we investigated the change in the level of plasma SIRT1 by injecting different concentrations of resveratrol into the uterus of Korean cattle heifer. The level of plasma SIRT1 in the 1.0 μM resveratrol-injected group was the highest among all groups (P < 0.05). Although the level of plasma SIRT1 increased on days 7, 9, and 14 in the resveratrol-injected group, the level of plasma SIRT1 in the control group decreased. When 1.0 µM resveratrol was directly injected into the uterus of cows during artificial insemination, a pregnancy rate was 21.0% higher than that in the control group. In conclusion, our results identified that the level of plasma SIRT1 was increased by direct injection of resveratrol and improved conception rate by injection into uterus of cow during artificial insemination.(AU)
