Core Tip
Core tip: Proteomics is an important tool for the identification of candidate cancer biomarkers since it allows the simultaneous analysis of multiple differentially expressed proteins in a single study. This review provides an overview of recent reports focused on the different proteomic tools used for the discovery of candidate protein markers for colorectal cancer (CRC), such as two-dimensional electrophoresis methods, quantitative mass spectrometry-based techniques or protein microarrays. We also emphasize the use of different samples including cell lines, murine models, clinical samples as tissue, serum or faeces, for CRC biomarker discovery, discussing their advantages and disadvantages, and finally summarize the candidate CRC markers most frequently identified.
