To explore whether the effects of lincRNA P7 on HCC cells are related to STAT1 protein, we also assessed the STAT1 levels in cells with altered lincRNA P7 expression and found that overexpression of lincRNA P7 decreased the levels of phosphorylated STAT1, whereas the knockdown of lincRNA P7 showed the opposite effect to increase the levels of phosphorylated STAT1 (Figure 3D). The gene discussed is STAT1; the disease is hepatocellular carcinoma.
