Furthermore, HCC tissues with high MCM3AP-AS1 or low miR-194-5p level showed an obvious higher level of FOXA1 protein compared to cases with low MCM3AP-AS1 or high miR-194-5p level (P < 0.05, Additional file 6: Figure S6D and S6E). The gene discussed is MCM3AP; the disease is hepatocellular carcinoma.
