The importance of store-operated Ca 2+  entry (SOCE) and the role of its key molecular regulators, STIM1 and ORAI1, in the development of cancer are emerging. Here, we report an unexpected dual function of SOCE in prostate cancer progression by revealing a decrease in the expression of STIM1 in human hyperplasia and tumor tissues of high histological grade and by demonstrating that STIM1 and ORAI1 inhibit cell growth by arresting the G0/G1 phase and enhancing cell senescence in human prostate cancer cells. In addition, STIM1 and ORAI1 inhibited NF-κB signaling and remodeled the tumor microenvironment by reducing the formation of M2 phenotype macrophages, possibly creating an unfavorable tumor microenvironment and inhibiting cancer development. However, STIM1 also promoted cell migration and the epithelial-to-mesenchymal transition by activating TGF-β, Snail and Wnt/β-Catenin pathways. Thus, our study revealed novel regulatory effects and the mechanisms by which STIM1 affects cell senescence, tumor migration and the tumor microenvironment, revealing that STIM1 has multiple functions in prostate cancer cells.

STIM1 accelerates cell senescence in a remodeled microenvironment but enhances the epithelial-to-mesenchymal transition in prostate cancer
