Proteomics is not only a biomarker discovery tool

The relatively young science of proteomics has been extensively used to identify biomarkers. However, a detailed and careful interpretation of proteomics data can also provide a dear picture of integrated biochemical systems, which can lead to a better comprehension of pathological processes. For example, the proteome analysis of human brain tissue from patients with schizophrenia, bipolar disorder, or multiple sclerosis compared with healthy controls has identified differentially expressed proteins that may not only be potential biomarkers but may also provide information that may increase the comprehension of these neurological disorders. Thus, proteomics is not only a biomarker discovery tool but can also identify potential players of relevance for diseases.
