This article aims to explore the optimal anti-osteoporotic ingredient and its precise mechanisms in mice models.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> In this study, we first screened the optimal anti-osteoporosis fraction of SSTZF extract <jats:italic>in vivo<\/jats:italic>, and then further explored the mechanism of its effects both <jats:italic>in vivo<\/jats:italic> and <jats:italic>in vitro<\/jats:italic>. Ten-week-old female C57BL\/6J mice were administrated with each fraction of SSTZF. At 10\u00a0weeks after ovariectomy (OVX), femurs were collected for tissue analyses, including histology, micro-CT, biomechanical tests, and immunohistochemistry for ALP, FABP4, and \u03b2-catenin. Additionally, we also evaluated the mRNA expression level of ALP and FABP4 and the protein expression level of \u03b2-catenin after being treated with SSTZF extract in C<jats:sub>3<\/jats:sub>H<jats:sub>10<\/jats:sub>T1\/2 cells. Moreover, we investigated the anti-osteoporosis effect of SSTZF extract on mice with <jats:italic>\u03b2-catenin<\/jats:italic> conditional knockout in growth plate chondrocytes (<jats:italic>\u03b2-catenin<\/jats:italic><jats:sup><jats:italic>Gli1ER<\/jats:italic><\/jats:sup> mice) through \u03bcCT, histology, and immunohistochemistry analyzes.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> At 10\u00a0weeks after treatment, osteoporosis-like phenotype were significantly ameliorated in SSTZF n-butanol extract (SSTZF-NB) group mice, as indicated by increased trabecular bone area and ALP content, and decreased lipid droplet area and FABP4 content. No such improvements were observed after being treated with other extracts, demonstrating that SSTZF-NB is the optimal anti-osteoporosis fraction. Additionally, the elevated \u03b2-catenin was revealed in both OVX mice and C<jats:sub>3<\/jats:sub>H<jats:sub>10<\/jats:sub>T1\/2 cells with SSTZF-NB administered. Furthermore, a significant osteoporosis-like phenotype was observed in <jats:italic>\u03b2-catenin<\/jats:italic><jats:sup><jats:italic>Gli1ER<\/jats:italic><\/jats:sup> mice as expected. However, SSTZF-NB failed to rescue the deterioration in <jats:italic>\u03b2-catenin<\/jats:italic><jats:sup><jats:italic>Gli1ER<\/jats:italic><\/jats:sup> mice, no significant re-upregulated ALP and downregulated FABP4 were observed after being treated with SSTZF-NB, demonstrating that SSTZF-NB prevents bone loss mainly via \u03b2-catenin signaling.<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> SSTZF-NB enhances osteogenesis mainly via activation of \u03b2-catenin signaling in growth plate chondrocytes. SSTZF-NB is the optimal anti-osteoporosis fraction of SSTZF and it can be considered a salutary alternative therapeutic option for osteoporosis.<\/jats:p>","DOI":"10.3389\/fphar.2021.711004","type":"journal-article","created":{"date-parts":[[2021,9,25]],"date-time":"2021-09-25T00:46:15Z","timestamp":1632530775000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Fractions of Shen-Sui-Tong-Zhi Formula Enhance Osteogenesis Via Activation of \u03b2-Catenin Signaling in Growth Plate Chondrocytes"],"prefix":"10.3389","volume":"12","author":[{"given":"Rui","family":"Xu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qinghe","family":"Zeng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chenjie","family":"Xia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiali","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pinger","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shan","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenhua","family":"Yuan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhaohuan","family":"Lou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Houfu","family":"Lin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hanting","family":"Xia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuaijie","family":"Lv","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taotao","family":"Xu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peijian","family":"Tong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mancang","family":"Gu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongting","family":"Jin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2021,9,24]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"601","DOI":"10.1142\/S0192415X06004132","article-title":"Effects of Safflower Seed Oil in Osteoporosis Induced-Ovariectomized Rats","volume":"34","author":"Alam","year":"2006","journal-title":"Am.
