Fig. 7: Aberrant expression of PAUF (ZG16b) and Kaplan–Meier-analyzed overall survival in pancreatic cancer.

a PAUF expression in nontumor and tumor groups determined from gene expression data from NCBI GEO (accession numbers GSE15471, GSE16515, GSE28735, GSE32676, GSE55643, and GSE62452). b Relationship between PAUF expression and overall survival in the TCGA pancreatic cancer cohort (TCGA-PAAD). Gene expression was dichotomized into high and low values using the mean as the cutoff. HR, hazard ratio. c Kaplan–Meier survival analysis and the log-rank test were used to analyze the overall survival of patients according to the copy number of the PAUF gene in TCGA-PAAD.
