Linc00675 is a novel marker of short survival and recurrence in patients with pancreatic ductal adenocarcinoma

Figure 1 Expression of linc00675 in human pancreatic ductal adenocarcinoma cell lines and cancerous tissues. A: Heat map showing linc00675, HULC, MALAT1, and HOTAIR expression in the microarray analysis. The rectangular indicates the hybridization signal (replicate probes) of linc00675 in pancreatic ductal adenocarcinoma (PDAC) and chronic pancreatitis (CP) tissues; B: Quantitative real time-polymerase chain reaction analysis of linc00675 expression level in 90 cases of PDAC tissues. GAPDH was used as an internal control; C: The boxes represent the distribution of linc00675 expression from the 25^th to 75^th percentiles of all patient samples with the horizontal lines showing the median levels of linc00675, ^cP < 0.001, tumor vs para-tumor, Student’s t-test; D: Relative abundance of linc00675 in multiple pancreatic cancer cell lines. Data are represented as the mean ± SD from three independent experiments, ^bP < 0.01, ^cP < 0.001, the corresponding pancreatic cancer cell line vs HPDE6, Student’s t-test.
