Elevated FN1 protein and peptide abundances were observed in malignant populations from primary tumors, indicating the predominance of ‘Mes’ cells, while CDH1 had higher abundances in lymph nodes and implicated the presence of more ‘Epi’ phenotypes (nine matched FFPE tumor and metastasis that passed the PRM-MS quality control; p ≤ 0.05; two-sided paired Student’s t-test or two-sided Wilcoxon signed-rank test) (Fig. 3h, i; Supplementary Data 4-1 and 4-4). The gene discussed is CDH1; the disease is neoplasm.
