FNDC3B expression levels in normal tissues, pan-cancerous and PC tissues. A FNDC3B expression levels in various normal human tissues (data from NCBI, BioProject: PRJEB4337). B FNDC3B expression levels in tumor and normal samples based on TCGA and GTEx databases. C FNDC3B expression levels in PC and normal pancreatic tissues based on TCGA and GTEx databases. D–I FNDC3B expression levels between tumor and normal samples in GSE16515, GSE28735, GSE62165, GSE62452, GSE15471 and GSE101448 datasets. J Receiver operating characteristic curve was recruited to evaluate the diagnostic value of FNDC3B expression in PC. K Expression of FNDC3B in paired tumor tissues and adjacent nontumor tissues from seven PC patients. L Representative images of CXCL5 in tumor tissues and the adjacent nontumor tissues. *P < 0.05; **P < 0.01 and ***P < 0.001. AUC area under the curve, FNDC3B fibronectin type III domain containing 3B, GTEx genotype-tissues expression, ns not significant, PC pancreatic cancer, TCGA the cancer genome atlas, RPKM reads per kilobase per million, TPM transcripts per million, TPR true positive rate, FPR false positive rate
