Relative expression of DUXAP8 in pancreatic cancer tissues and its clinical significance. a Hierarchical clustering analysis of differentially expressed lncRNAs (fold change > 2; P < 0.05) in pancreatic cancer and normal tissues. b Overlap of dysregulated lncRNAs in three GEO datasets. c The DUXAP8 gene is located at the chromosomal locus 22q11.1 and encodes a 2107-bp transcript (https://www.ncbi.nlm.nih.gov). d Relative expression of DUXAP8 in pancreatic cancer tissues compared with paired adjacent normal tissues (n = 58), and DUXAP8 expression was classified into two groups. e DUXAP8 expression was significantly higher in patients with a larger tumor size and a more advanced pathological stage (shown as ΔCT). f Patients with high DUXAP8 expression had significantly shorter overall survival than patients with low DUXAP8 expression (P < 0.001, log rank test).
