Article Abstract
Objectives: The osteogenic differentiation ability of bone marrow mesenchymal stem cells (BMSCs) is an important aspect of studying osteoporosis (OP). This study aims to explore the role of SYVN1 in regulating the osteogenic differentiation of BMSCs and to suggest its potential as a treatment for OP.
Methods: BMSCs were differentiated using osteogenic induction. The expression of SYVN1 at different osteogenic induction time points was analyzed by Western blot (WB). The expression levels of osteogenic markers, including RUNX2, ALP, and OCN, were measured by RT-qPCR. EdU staining and colony formation assays were performed to evaluate the impact of SYVN1 on the proliferative ability of BMSCs. The effect of SYVN1 on osteogenic differentiation of BMSCs was assessed by alizarin red staining. The association of SYVN1 with the AMPK/mTOR pathway was confirmed through WB analysis.
Results: The expression of SYVN1 decreased as BMSCs differentiation progressed. Overexpression of SYVN1 inhibited the osteogenic differentiation and proliferation of BMSCs, whereas silencing SYVN1 had the opposite effect. Furthermore, SYVN1 overexpression reduced the p-AMPK/AMPK ratio and increased the p-mTOR/mTOR ratio, effects that were reversed by the AMPK activator A-769662.
Conclusion: SYVN1 overexpression inhibits the osteogenic differentiation and proliferation of BMSCs, potentially through modulation of the AMPK/mTOR pathway.

Postmenopausal osteoporosis (PMOP) is a common bone metabolic disorder in middle-aged and elderly women, yet its pathogenesis remains unclear. This study investigates the effect of nuclear factor erythroid 2-related factor 2 (Nrf2) deficiency on bone homeostasis to provide insight into the mechanisms underlying PMOP. Sixteen female SD rats were randomly assigned to Sham and ovariectomized (OVX) groups.

Background: Ossification of the posterior longitudinal ligament (OPLL) is a pathological condition characterized by ectopic ossification of spinal ligaments, primarily driven by abnormal osteogenic differentiation of ligament fibroblasts with stem cell-like properties. The SOX transcription factor family is crucial in regulating cell stemness and differentiation. Among them, SOX8 is known to influence osteoblast differentiation, but its role in OPLL remains unclear.

Introduction: During the healing process, the functional gradient attachment of the rotator cuff (RC) tendon-bone interface fails to regenerate, which severely impedes load transfer and stress dissipation, thereby increasing the risk of retears. As a result, the treatment of rotator cuff tears remains a significant clinical challenge.
Methods: In this study, a dual-crosslinked hyaluronic acid/polyethylene glycol (HA/PEG) hydrogel scaffold was synthesized using hyaluronic acid and polyethylene glycol as base materials.

Peri-implantitis (PI) is a major cause of implant restoration failure, necessitating therapeutic strategies that integrate bone regeneration and anti-inflammatory effects. Despite advances in treatment, no existing agents simultaneously address both objectives. Exosomes (Exos), as key mediators of intercellular communication, have demonstrated dual anti-inflammatory and osteogenic capacities through microRNA (miRNA) delivery; however, their potential in PI therapy remains unexplored.
