As an approach to explore the function of DAP3 in HCC progression, we selected Huh7 and Hep3B cells to establish cell lines with DAP3 knockdown (KD) or overexpression (OE) based on their basal expression levels (Fig. 2A, B; Supplementary Fig. S2A, B). This evidence concerns the gene DAP3 and hepatocellular carcinoma.
