Its targets were then subjected to Protein-Protein Interaction (PPI) and KEGG pathway analyses. Subsequently, a rat model of Achilles tendon injury was established. After a 4-week intervention with Tan IIA, its reparative effects were comprehensively evaluated using histological, biomechanical, immunohistochemical (IHC), and ELISA methods.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Network pharmacology predicted that Tan IIA acts through core targets such as AKT1 and EGFR to regulate pathways including PI3K-Akt and MAPK.\n In vivo<\/jats:italic>\n experiments confirmed that, compared to the model group, Tan IIA significantly improved tissue structure (histological score,\n P<\/jats:italic>\n &lt; 0.001) and enhanced the ultimate tensile load (\n P<\/jats:italic>\n &lt; 0.01). It also upregulated Collagen Type I (COL\u2160) expression (\n P<\/jats:italic>\n &lt; 0.05) while downregulating Vascular Endothelial Growth Factor A (VEGFA) expression (\n P<\/jats:italic>\n &lt; 0.01), and effectively modulated serum inflammation by decreasing IL-6 (\n P<\/jats:italic>\n &lt; 0.01) while increasing IL-10 and TGF-\u03b2 (\n P<\/jats:italic>\n &lt; 0.05).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Tan IIA is the key bioactive component of Salvia miltiorrhiza for repairing Achilles tendon injury. It effectively promotes the structural and functional healing of the tendon by synergistically regulating key processes such as inflammation, matrix remodeling, and angiogenesis.<\/jats:p>\n <\/jats:sec>","DOI":"10.3389\/fphar.2025.1673962","type":"journal-article","created":{"date-parts":[[2025,11,13]],"date-time":"2025-11-13T06:32:01Z","timestamp":1763015521000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Salvia miltiorrhiza (Danshen) promotes Achilles tendon repair: from network pharmacology prediction to in vivo mechanistic validation"],"prefix":"10.3389","volume":"16","author":[{"given":"Yu","family":"Wang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xianyan","family":"Xie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gaoyuan","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ziyan","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuqi","family":"Qin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junze","family":"Luo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoxu","family":"Jia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yifeng","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lin","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huiguo","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,11,13]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"369","DOI":"10.1089\/ten.teb.2022.0188","article-title":"Drug delivery approaches to improve Tendon healing","volume":"29","author":"Adjei-Sowah","year":"2023","journal-title":"Tissue Eng.
