Pulsed electromagnetic fields regulate osteocyte apoptosis, RANKL/OPG expression, and its control of osteoclastogenesis depending on the presence of primary cilia
This study enriches our basic knowledge for further understanding the biological behaviors of osteocytes, and is also helpful for providing a more comprehensive mechanistic understanding of the effect of electromagnetic stimulation on bone and relevant skeletal diseases (e.g., bone fractu re and osteoporosis). AbstractGrowing evidence has shown that pulsed electromagnetic fields (PEMF) can modulate bone metabolism in vivo and regulate the activities of osteoblasts and osteoclasts in vitro. Osteocytes, accounting for 95% of bone cells, act as the major mechanosensors in bone for transducing external mechanical signals and p...

P53 Dependent Mitochondrial Permeability Transition Pore Opening Is Required for Dexamethasone‐Induced Death of Osteoblasts
Prolonged or overdose glucocorticoids (GCs) usage is the common cause of osteoporosis. In the present study, we studied the cellular mechanism of dexamethasone (Dex)‐induce osteoblast cell death by focusing on the role of mitochondrial permeability transition pore (mPTP). In cultured osteoblastic MC3T3‐E1 cells, Dex‐induced mPTP opening, which was demonstrated by mitochondrial membrane potential (MPP) decrease, cyclophilin‐D (CyPD)–adenine nucleotide translocator 1 (ANT‐1) mitochondrial complexation and cytochrome C (cyto‐C) release. The mPTP inhibitor sanglifehrin A (SfA) dramatically inhibited Dex‐induced...
