Abstract
: Natural herbal medicines have been developed for the treatment and prevention of women’s menopausal symptoms. In this study, we investigated the anti-menopausal effects of Cornus officinalis (CO) and Ribes fasciculatum (RF) extracts in 3T3-L1 preadipocytes, MC3T3-E1 preosteoblasts, and COV434 granulosa cells in vitro and ovariectomized (OVX) ddY mice in vivo. Combination treatment of CO and RF extract at 7:3 ratio inhibited lipid accumulation via Plin1 and Adipoq downregulation in a cocktail of dexamethasone, 3-isobutyl-1-methylxanthine, and insulin (DMI)-induced differentiated 3T3-L1 cells. In addition, CO + RF treatment significantly enhanced osteoblastic differentiation, with mineralized nodule formation occurring through the upregulation of osteoblast-inducing markers in osteoblastic MC3T3-E1 cells. Increased production of estradiol and mRNA expression of ERα (ESR1) were observed in androstenedione-induced COV434 granulosa cells treated with the CO + RF extract. In CO + RF-treated mice, fatty hepatocyte deposition and abdominal visceral fat tissues reduced with OVX-induced uterine atrophy. Furthermore, bone mineral density and bone mineral content were significantly enhanced by CO + RF in mouse models of ovariectomy-induced femoral bone loss. Taken together, our findings suggested that CO + RF promoted estrogenic activity and had anti-obesity and anti-osteoporotic effects in vitro and in vivo. Thus, a combination of CO and RF extracts may be a good therapeutic strategy for managing women’s menopausal syndromes.
