lncRNA PITPNA-AS1 promotes cell proliferation and metastasis in hepatocellular carcinoma by upregulating PDGFD
Figure 1. PITPNA-AS1 is overexpressed in HCC and associates with poor prognosis. (A) Relative mRNA level of PITPNA-AS1 in TCGA datasets was analyzed using GEPIA. (B) Relative mRNA level of PITPNA-AS1 in 50 pairs of tumor tissues and adjacent normal tissues were assessed using qRT-PCR. (C) Relative mRNA level of PITPNA-AS1 in HCC cell lines (Huh7, BEL-7404, HCCLM3, Hep3B) and the control cell line, THLE-3. (D) Correlation of PITPNA-AS1 expression levels with patients’ survival was evaluated by the Kaplan-Meier analysis. *P < 0.05, **P < 0.01.
