RAD52 and hepatocellular carcinoma: To further investigate the influence of the exon 10 inclusion of RAD52 in HCC tissues on the overall survival (OS) and relapse-free survival (RFS) in our clinical cohort, we designed the probes specifically targeting exon 10 of RAD52 for RNA In Situ Hybridization to detect the quantity of RAD52 with or without exon 10 using paraffin sections (Supplementary Fig. 5c).
