However, the role of DUSP1 medroxyprogesterone （MPA） are still unclear. phosphatase I （DUSPI） was differentially expressed in endometrioid in EEA progression and the relationship between DUSPI and Methods： The expression of DUSPI in EEA specimens was detected by immunohistochemical analysis. The effect of DUSPI on cell proliferation was analyzed by Cell Counting Kit 8 and colony formation assay, and cell migration was analyzed by transwell assay. MPA-induced DUSPI expression in EEA cells was measured by Western blot. Results： DUSPI expression was deficient in advanced International Federation of Gynecology and Obstetrics stage, high-grade and myometrial invasive EEA. In EEA cell lines （HeclA, Hecl B, RL952, and Ishikawa）, the DUSP1 expression was substantially higher in lshikawa cells than in other cell lines （P 〈 0.05）. Knockdown ofDUSP I promoted lshikawa cells proliferation, migration, and activation of mitogen-activated protein kinases/extracellular signal-regulated kinase （MAPK/Erk） pathway. MPA-induced DUSP1 expression and inhibited MAPK/Erk pathway in Ishikawa cells. Conclusions： Our data suggest that DUSP1 deficiency promotes EEA progression via MAPK/Erk pathway, which may be reversed by MPA, suggesting that DUSP I may serve as a potential therapeutic target for the treatment of EEA.展开更多
