Research advances in the mechanism of action of cell senescence and mitochondrial dysfunction in osteoporosis
Osteoporosis(OP) is a systemic bone disease closely associated with aging,and it is characterized by low bone mass,deterioration of bone tissue microarchitecture,and increased bone fragility. With the exacerbation of population aging in China,there has been a rapid increase in the prevalence rate of OP,and OP has become a serious public health concern. Recent studies have confirmed that cell senescence and mitochondrial dysfunction are two core mechanisms driving age-related OP,with the presence of profound crosstalk between them. The senescence of bone marrow mesenchymal stem cells disrupts the bone microenvironment through an “osteogenic-adipogenic” differentiation shift and the paracrine effect of the senescence-associated secretory phenotype(SASP),while mitochondrial dysfunction regulates osteoblast and osteoclast function through energy metabolism disorders,oxidative stress,impaired autophagy,and imbalance in mitochondrial dynamics. Mitochondrial dysfunction-associated senescence(MiDAS) acts as a critical hub,mediating the formation of a vicious cycle of “mitochondrial dysfunction→MiDAS→cell senescence→SASP→further mitochondrial impairment”,which accelerates bone metabolic imbalance. This article systematically reviews the mechanism of action of cell senescence and mitochondrial dysfunction in OP,with a focus on dissecting the MiDAS-mediated crosstalk,in order to provide a clear theoretical framework and potential targets for developing novel anti-OP therapies that target senescent cells or improve mitochondrial function.
