Figure 3. The expression of miR-6742-5p in human lung adenocarcinoma and its roles in nude mice. (A) Relative expression of miR-6742-5p in human lung adenocarcinoma and their paracancerous tissues, tested by quantitative real-time PCR. (B, a) the volume of H522 tumor in miR-6742-5p NC and OE group; (B, b) HE staining of nude mice’ tumors; (B, c) statistic data for tumor volume. (A) ** P=0.0001 miR-6742-5p OE group vs NC group; (B) **P=0.0001 miR-6742-5p OE group vs NC group.
