Identification and verification of DEPs in ESCC tissues. a Paired ESCC and adjacent normal esophageal tissues from three patients were analyzed by TMT. Twofold change was defined as the threshold for a significant change in expression. We detected 39 proteins up-regulated in cancer tissues compared with that in adjacent normal tissues (paired-samples t-test, p < 0.001). b Gene ontology enrichment analysis of identified DEPs which were classified into cellular component, molecular function, and biological process. c, d Validation of DEPs in ESCA. The expression of FN1, LTBP1, PLOD2, THBS1 and RCN3 were confirmed by GEPIA and western blot analysis. N non-tumorous tissues, T tumorous tissues. (one-way ANOVA and paired-samples t-test, *p < 0.05)
