SREK1 and hepatocellular carcinoma: To identify other common targeted genes by miR-30c-5p and miR-30e-5p that are also correlated well with SREK1 expression in HCC tissues, the downstream targets analysis of two microRNAs was further performed by Targetscan and miRDB31,32, and the correlation of the targets with SREK1 expression in TCGA HCC database was also analyzed.
