NR2F1 and hepatocellular carcinoma: Then, qRT-PCR was applied to investigate the correlation of NR2F1-AS1 with miR-642a, and the findings exhibited that overexpression of NR2F1-AS1 significantly decreased miR-642a expression, while knockdown of NR2F1-AS1 markedly increased miR-642a expression in both two HCC cells (Figure 3(e)), indicating a negative correlation of NR2F1-AS1 with miR-642a.
