Abstract:

BACKGROUND: As the multipotent differentiation potential, bone marrow mesenchymal stem cells exert an important role in bone metabolism disorders, which is regulated by a variety of hormones and cytokines. Currently, the epigenetic regulatory mechanisms underlying osteogenic differentiation of bone marrow mesenchymal stem cells are unclear, and association between histone deacetylase (Hdac) and osteoporosis needs to be further explored.
OBJECTIVE: To investigate the epigenetic mechanisms of bone formation by analyzing the expression of Hdac1, 3, 4 mRNA profile in bone marrow mesenchymal stem cells isolated from ovariectomized mice.
METHODS: A total 30 female healthy Kunming mice were randomly divided into sham group and ovariectomy group. After 7 days of adaptive feeding, mice in the ovariectomized group (n=15) were subject to bilateral ovariectomy; mice in sham group (n=15) were sham-operated.
RESULTS AND CONCLUSION: In the ovariectomy group, the trabecular bone of the femur was sparse or broken, the width of trabecular bone was narrowed, the trabecular separation was widened, and the trabecular bone volume was reduced. The level of Hdac3 mRNA was lower in bone marrow mesenchymal stem cells from ovariectomized mice compared with controls, but there was no significance between Hdac1, Hdac4 mRNA expression of the two groups. These findings demonstrate that Hdac might play an important role in bone remodeling in the model of estrogen deficiency-induced osteoporosis.
