Compared with the protein concentrations in normal mucosa, the scores of TPM3, CAMP, ERp29, and HSPA8 in the tumor samples showed significant differences (Wilcoxon signed-rank test, P = 0.013 for TPM3, P = 0.003 for ERp29, P = 0.011 for CAMP, P < 0.001 for HSPA8). This evidence concerns the gene ERP29 and neoplasm.
