In this study, we established a mouse model of prosthetic loosening and evaluated the therapeutic effects of targeting tumor necrosis factor-alpha (<jats:italic>TNF-\u03b1<\/jats:italic>) and wingless-type MMTV integration site family, member 3A (<jats:italic>Wnt3a<\/jats:italic>) on osteolysis. <jats:italic>TNF-\u03b1<\/jats:italic> knockdown reduced inflammation and osteoclast-related gene expression, while <jats:italic>Wnt3a<\/jats:italic> overexpression increased osteoblast-related gene expression. Notably, the combination of these interventions showed superior efficacy in inhibiting osteolysis compared to monotherapy. Biomechanical imaging and histological staining revealed that combined therapy enhanced bone density and minimized the gaps between the peri-prosthetic bone and the prosthesis, reducing fibrous connective tissue proliferation. Adeno-associated virus-mediated gene therapy was found to be safe, with no adverse effects observed in liver, brain, spleen, and kidney tissues. Our findings suggest that combining <jats:italic>TNF-\u03b1<\/jats:italic> silencing with <jats:italic>Wnt3a<\/jats:italic> overexpression may be a promising approach for treating particle-induced peri-implant osteolysis and warrants further clinical investigation.<\/jats:p>","DOI":"10.3389\/fcell.2025.1511577","type":"journal-article","created":{"date-parts":[[2025,3,6]],"date-time":"2025-03-06T06:50:51Z","timestamp":1741243851000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Combining TNF-\u03b1 silencing with Wnt3a overexpression: a promising gene therapy for particle-induced periprosthetic osteolysis"],"prefix":"10.3389","volume":"13","author":[{"given":"Ping","family":"Chen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Long","family":"Wu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuai","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qunhua","family":"Jin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kening","family":"Sun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2025,3,6]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"2398","DOI":"10.1002\/jcp.26111","article-title":"GSK-3\u03b2 inhibition suppresses instability-induced osteolysis by a dual action on osteoblast and osteoclast differentiation","volume":"233","author":"Amirhosseini","year":"2018","journal-title":"J.
