legend. TCGA database exploration of mir-767-105 cluster in hepatocellular carcinoma (HCC). a Top 10 mirna expression levels in HCC. The top 1–3 belonged to mir-767-105 cluster. b Comprehensive comparison of the mir-767-105 cluster expression levels between the HCC samples and non-tumour samples. Error bars represented the mean ± SEM. ****represent a P -value < 0.0001. P-value was calculated with the Mann-Whitney test. c Heatmap of mir-767-105 expression levels from 50 non-tumour samples and 373 HCC samples. d Kaplan-Meier survival analysis with log-rank test between the low and high expression of the mir-767(left), mir-105-1(middle), and mir-105a-2(right) expression levels was performed. e-f The results of univariate Cox analysis was shown with the forest plot, and the multivariate Cox analysis was shown as Table. g The items from Gene Ontology in biological process, cellular component and molecular function. h The top 20 items from Kyoto Encyclopedia of Genes and Genomes
