arzoxifene (LY353381)

Ishikawa cells and ECC-1 cells were stimulated with estradiol (E2) or the selective estrogen receptor modulator Arzoxifene, and qPCR was performed to measure gene expression changes... Estrogen promotes cell proliferation and inhibits apoptosis by upregulating ZNF626 and SLK, while downregulating RFWD3. Furthermore, estrogen induces a shift in the tumor microenvironment, characterized by a reduction in memory CD4+ T cells and a transition from M1 to M2 macrophage phenotypes, thus facilitating the onset and progression of EC.
