LncRNA PVT1 is often overexpressed in PDAC cancer and correlates with poor prognosis. (A) The level of PVT1 mRNA was measured by qRT-PCR in PDAC tissues and corresponding noncancerous tissues (n = 30). Data are indicated with medians and quartiles. (B) The level of PVT1 mRNA was measured by qRT-PCR in the normal pancreatic cell line H6C7 and various pancreatic cancer cell lines (HPAC, DANG, BXPC3, PANC1, and ASPC-1). Data are shown as the mean ± SD, n=3. (C) Expression levels of PVT1 in the TCGA cohort. Kaplan-Meier analysis of the correlation between PVT1 expression and overall survival in the TCGA cohort. The median level of PVT1 is used as the cutoff. (*P < 0.05, **P < 0.01, ***P < 0.001)
