Here, we also determined the expression of miR-211 in ovarian cancer cells with 0, 3 and 12 mg/ml of CFG treatment for 24 h and found that CFG could not influence the expression of miR-211, suggesting that CFG-induced PHF19 downregulation is not mediated by miR-211 (Figure S3). This evidence concerns the gene PHF19 and ovarian carcinoma.
