摘要: Bisphosphonates are the mainstay of therapy worldwide for osteoporosis. However, bisphosphonates also have limitations. The objective this study was to determine role miR-101-3p/Rap1b signal pathway in osteoclast differentiation after treatment with bisphosphonates. Our results revealed that miR-101-3p an important regulator treated-osteoclasts. When down-regulated bone marrow-derived macrophage-like cells (BMMs), development mature osteoclasts promoted, and vice versa. alendronate decreased multinucleated cell number regardless whether knocked down or over-expressed. TRAP activity assay confirmed above results. Luciferase indicated a negative Rap1b. Western blot analysis protein expression level Rap1b BMMs transfected OV-miR-101-3p lower than empty vector. overexpression increased TRAP-positive cells, while inhibition numbers. In vivo data showed inhibited ovariectomized mice overexpressed blocked differentiation. Taken together, our demonstrate plays key [BMB Reports 2019; 52(9): 572-576].
