Proteomics is particularly well suited for the analysis of the microenvironment, given the host origin of numerous components of the microenvironment that lack discernible genomic alterations, and given the contribution of protein release and shedding of proteins from the surface of cancer cells that cannot be predicted strictly from genomic analysis.Published: 27 February 2014 References 1.
