Exosomes, extracellular vesicles measuring 40-160 nm in diameter, are critical mediators of intercellular communication. Among their bioactive components, microRNAs (miRNAs) have garnered attention for their role in the pathogenesis of Osteoporosis. Through complementary binding to the 3' untranslated regions of target genes, miRNAs regulate key processes such as bone formation, bone resorption, angiogenesis, and bone immunity. This review provides a comprehensive summary of the regulatory roles and underlying mechanisms of miRNAs in osteoporosis, offering insights into potential therapeutic strategies.

Osteoporosis is a prevalent metabolic bone disorder with complex molecular underpinnings. Emerging evidence implicates endoplasmic reticulum stress (ERS) in its pathogenesis; however, systematic exploration of ERS-related genes (ERSRGs) remains limited. This study aimed to identify ERS-related differentially expressed genes (ERSRDEGs) in osteoporosis, construct a diagnostic model, and elucidate associated molecular mechanisms.

Bisphenol A (BPA) and di-n-butyl phthalate (DBP) are ubiquitous endocrine disruptors implicated in bone metabolism disorders, but their precise mechanisms remain unclear. Here, we demonstrated that BPA and DBP bidirectionally disrupt bone homeostasis by targeting CD36 in bone marrow-derived mesenchymal stem cells (BMSCs). Mechanistically, both chemicals upregulate CD36 expression, which sequesters ATG9a at the Golgi apparatus, inhibits autophagosome maturation, and thereby impairs osteogenic differentiation of BMSCs, as evidenced by reduced ALP and RUNX-2 levels.

Bone integrity is maintained through continuous remodeling, orchestrated by the coordinated actions of osteocytes, osteoblasts, and osteoclasts. Once considered passive bystanders, osteocytes are now recognized as central regulators of this process, mediating biochemical signaling and mechanotransduction. Malfunctioning osteocytes contribute to serious skeletal disorders such as osteoporosis.

Extracellular vesicles (EVs) are nanoscale, membrane-bound particles secreted by diverse cell types and act as pivotal mediators of intercellular communication during bone regeneration. These vesicles transport bioactive cargo including proteins, lipids, mRNAs, and microRNAs that modulate osteogenesis, angiogenesis, and immune responses within the bone microenvironment. EVs originating from mesenchymal stem cells, osteoblasts, endothelial cells, and macrophages have demonstrated substantial potential to promote bone formation, inhibit bone resorption, and enhance vascularization.
