Currently, the pathogenesis of prostate diseases is still under investigation, but it is generally clinically recognized to be related to the imbalance of prostate cell viability. Trichomonas vaginalis macrophage migration inhibitory factor (TvMIF) has been reported to induce the proliferation and invasion of prostate cancer cells, but for normal PECs, the relationship between them has not been reliably confirmed. Therefore, this research aims to determine the influence of macrophage TvMIF on prostate epithelial cells (PECs) and its preliminary mechanism. The activity of RWPE‐1 human normal prostate epithelial cells, the inflammatory response state, the expression of miR‐451, and the effect of miR‐451 on RWPE‐1 were detected after TvMIF intervention. We found that TvMIF can enhance RWPE‐1 cell proliferation and activate inflammatory factors by suppressing miR‐451, thus taking part in the development and proliferation of diseases such as prostatic hyperplasia and prostatitis.
