TRIM27 and hepatocellular carcinoma: Results of the MTT assay, colony formation assay, and Transwell migration and invasion assay revealed that HCC cells co-transfected with miR-30b-3p mimics plus a TRIM27 overexpression vector showed higher cell viability, a higher colony formation rate and greater Transwell migration and invasion ability, compared with the group co-transfected with miR-30b-3p mimics plus empty vector, indicating that the suppressive role of miR-30b-3p overexpression on the malignant phenotypes of HCC cells was partly counteracted by TRIM27 overexpression (Figures 4A–D).
