DNASE1L3 and hepatocellular carcinoma: To further determine the expression of DNASE1L3 in HCC, the level of DNASE1L3 mRNA in 28 pairs of HCC tissues and their matched adjacent non‐tumour tissues were detected by RT‐qPCR, and the protein level of DNASE1L3 in 12 pairs of HCC samples containing adjacent non‐tumour samples were tested by Western Blot.
