ALKBH5 and ovarian cancer: To verify the effect of ALKBH5 in FSH-promoted progression of epithelial ovarian cancer in vivo, the ovariectomized nude mice were intraperitoneally injected with SK-OV3 cells transfected with empty lentivirus (Lv-Empty) or ALKBH5 shRNA lentivirus (Lv-shALKBH5) to establish peritoneal metastatic models of ovarian cancer (Figure S5A).
