Abstract

The present study aimed to explore the expression of microribonucleic acid (microRNA) (miR)‑205 in bone tissues and serum of elderly female patients with type 2 diabetes mellitus (T2DM) complicated with osteoporosis (OP), and to investigate the effect of miR‑205 on osteogenesis/adipogenesis of bone marrow mesenchymal stem cells (BMSCs) and its mechanism in elderly female mice with T2DM + OP. The bone tissues and serum of 24 female patients with T2DM + OP at the Third Affiliated Hospital of Qiqihar Medical University were collected as the research group, while those of 24 healthy people were collected as the control group. The expression level of miR‑205 was detected in both groups via reverse transcription‑polymerase chain reaction (RT‑PCR). Then the elderly female mouse model of T2DM + OP was established as a model group, while normal mice of the same age were used as the control group. The mice in the model and control groups were transfected with miR‑205 mimic, negative control (NC)‑mimic, miR‑205‑inhibitor and NC‑inhibitor. Alizarin red S (ARS) staining and RT‑PCR were conducted after osteogenic induction for 21 days, and oil red O (ORO) staining and RT‑PCR were performed after adipogenic induction for 24 days. The overexpression of miR‑205 inhibited osteogenic differentiation and promoted adipogenic differentiation of BMSCs in elderly female mice with T2DM + OP, while knockdown of miR‑205 promoted osteogenic differentiation and inhibited adipogenic differentiation of BMSCs in elderly female mice with T2DM + OP. In addition, miR‑205 was able to directly suppress the expression of its target gene RUNX family transcription factor 2 (Runx2). The expression level of miR‑205 was obviously increased in female patients with T2DM + OP and the elderly female mouse model of T2DM + OP. In addition, miR‑205 was able to regulate the osteogenic/adipogenic differentiation of BMSCs, and miR‑205/Runx2 may be a new method and target for the treatment of female patients with T2DM + OP.
