Key oxidative phosphorylation (OXPHOS)\u2010related genes, such as COX15, COX4I1, COX5B, COX7A1, COX8A, NDUFA12, NDUFA5, NDUFB10, NDUFB3, NDUFC1, NDUFS1, and NDUFS4, were found to be significantly downregulated in lesional tendons compared with non\u2010lesional ones, indicating impaired energy metabolism. This reduction in OXPHOS activity may contribute to increased necroptosis in chronic tendon injuries. Furthermore, bisphenol A and valproic acid were found to activate OXPHOS\u2010related genes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The findings highlighted the crucial role of OXPHOS in maintaining tendon homeostasis and demonstrated potential therapeutic strategies targeting the OXPHOS pathway, such as bisphenol A and valproic acid, to enhance healing in chronic tendon conditions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The crucial role of OXPHOS in maintaining tendon homeostasis underscores its potential as a therapeutic target, reflecting that strategies aimed at modulating the OXPHOS pathway may provide promising treatment options.<\/jats:p>\n                    <jats:p>Chronic tendon injuries present a major clinical challenge with limited treatments. This study investigated the molecular mechanisms underlying these injuries using bulk and single\u2010cell RNA sequencing. We identified significant downregulation of oxidative phosphorylation (OXPHOS)\u2010related genes in lesional tendons across multiple cell types, contributing to increased necroptosis. In\u00a0vitro experiments and molecular docking revealed that valproic acid activates OXPHOS and inhibits necroptosis. These findings highlight the critical role of mitochondrial function in tendon homeostasis and suggest valproic acid as a promising therapeutic candidate for treating chronic tendon injuries by restoring OXPHOS activity.<\/jats:p>\n
