Human bladder cancer and colon cancer quatitative MS/MS


ABSTRACT: We analyzed a set of 40 independently collected tumor tissue/control samples using a label-free quantitation single pass LC-MS/MS approach. In this set, 10 samples originated from a colon tumor (i.e. AC) and 10 from control non-malignant tissue samples (NCA), as well as 10 from BC samples and 10 from control bladder tissue (NCB) samples.

Proteolytic cascades are deeply involved in critical stages of cancer progression. During the course of peptide-wise analysis of shotgun proteomic data sets representative of colon adenocarcinoma (AC) and ulcerative colitis (UC), we detected a cancer-specific proteolytic fingerprint composed of a set of numerous protein fragments cleaved C-terminally to V, I, A, T, or C residues, significantly overrepresented in AC. A peptide set linked by a common VIATC cleavage consensus was the only prominent  ...[more]
