Prior studies have demonstrated that GAS5 inhibits breast cancer progression through adsorbing distinct miRNAs (e.g., miR-221-3p, miR-196a-5p, miR-378a-5p, miR-23a, and miR-103) as an miRNA sponge and further up-regulating miRNA target proteins [35–38]. The gene discussed is GAS5; the disease is breast carcinoma.
