RAD52 expression was significantly upregulated in Chinese HCC tissues compared to their paired adjacent (peritumoral) tissues. a mRNA expression of RAD52 detected by qRT-PCR in HCC. Upregulated mRNA was shown in HCC tissues (*P ≤ 0.05). b RAD52 protein levels were measured by Western blotting. Lanes 1, 3, and 5 represent cancer tissues. Lanes 2, 4, and 6 represent adjacent tissues. Increased RAD52 protein expression was observed in HCC tissues. c RAD52 immunohistochemical testing in 70 paired HCC tissues and adjacent nontumor tissues. Representative IHC images of RAD52 expression are shown in the panel. The left is HCC tissues with high expression. The right is nontumor tissues with low expression
