Figure 1. — PCED1B-AS1 is upregulated in PDAC tissues and cells. (A) Expression levels of PCED1B-AS1 in the PDAC tissues based on data obtained from GEPIA. (B) Relative expression levels of PCED1B-AS1 in 47 cases of PDAC tissues and the corresponding non-tumor tissues were detected using RT-qPCR. (C) RT-qPCR was used to detect the expression levels of PCED1B-AS1 in the normal human pancreatic ductal epithelial cell line HPDE6-C7 and the five PDAC cell lines, AsPC-1, PANC-1, CFPAC-1, SW1990 and BxPC-3. *P<0.05, **P<0.01, ***P<0.001 vs. normal tissues or the HPDE6-C7 cell line. GEPIA, Gene Expression Profiling Interactive Analysis; PDAC, pancreatic ductal adenocarcinoma; PCED1B-AS1, PC-esterase domain containing 1B-antisense RNA 1; RT-qPCR, reverse transcription-quantitative PCR.
