Data mining of RAD52 in the TCGA database. a RAD52 mRNA expression in HCC tissues and normal tissues. RNA-seq data were quantified using RSEM. Significant differences were observed between HCC tissues and normal tissues. Higher expression of RAD52 in HCC tissues than in normal tissues was obtained (***P ≤ 0.001). b Receiver-operation characteristic (ROC) curve of RAD52. The AUC of RAD52 was 0.704. The sensitivity and specificity were 61.20% and 71.00%, respectively. c Overall survival (OS) curve according to RAD52 expression in HCC. d Recurrence-free survival (RFS) of RAD52 expression in HCC
