CXCL11 and ovarian carcinoma: Using ERα‐positive TOV2295 and TOV3133G cells generated from human ovarian carcinomas (Letourneau et al., 2012), we also found a similar expression profile with the upregulation of CXCR7 and CXCL11 in response to estrogen, which further validates the distinct regulation in OC cells (Fig. 2D).
