Psoralen is an effective ingredient extracted from <jats:italic>Cullen corylifolium<\/jats:italic> (L.) Medik. with multiple bioactivities mainly including anti-osteoporotic, anti-tumor, anti-inflammatory, and estrogen-like effects. However, the exact role of psoralen on trophoblast invasiveness has not been investigated thus far. In the present study, the effects of psoralen on the proliferation, migration, and invasion abilities of HTR-8\/SVneo cells were evaluated by the CCK-8 and Transwell assays. The expression patterns of nuclear factor \u03baB (NF-\u03baB)\/p65 and metalloproteinases (MMP)-2 and MMP-9 were characterized by further experiments including real-time quantitative polymerase chain reaction and Western blot. Indirect immunofluorescence was applied to track the NF-\u03baB p65 translocation. Herein, we found that cell viability and invasive ability were promoted by psoralen in a concentration-dependent manner. Psoralen concentration-dependently enhanced both MMP-2 and MMP-9 expression and their activity of HTR-8\/SVneo cells. Additionally, we observed accelerated nuclear accumulation and enhanced nuclear translocation of p65 in the presence of psoralen. Furthermore, invasiveness enhancement of psoralen on HTR-8\/SVneo cells was partly eliminated by a NF-\u03baB pathway inhibitor. Thus, our findings suggest that psoralen may serve as a potential repurpose drug candidate that can be used to induce migration and invasion of trophoblast cells through strengthening the NF-\u03baB pathway.<\/jats:p>","DOI":"10.3389\/fphar.2022.804400","type":"journal-article","created":{"date-parts":[[2022,4,8]],"date-time":"2022-04-08T05:12:52Z","timestamp":1649394772000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":6,"title":["Psoralen Promotes Proliferation, Migration, and Invasion of Human Extravillous Trophoblast Derived HTR-8\/Svneo Cells in vitro by NF-\u03baB Pathway"],"prefix":"10.3389","volume":"13","author":[{"given":"Dan","family":"Qi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingyuan","family":"Lu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ziyi","family":"Fu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shanshan","family":"Lv","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lili","family":"Hou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,4,8]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"501","DOI":"10.1093\/humupd\/dmaa017","article-title":"Investigation of Human Trophoblast Invasion In Vitro","volume":"26","author":"Abbas","year":"2020","journal-title":"Hum.
