Proteomic and metabolic prediction of response to therapy in gastric cancer

Figure 2 Matrix-assisted laser desorption-ionization imaging mass spectrometric profiles of breast and gastric cancer tissues. Human epidermal growth factor receptor-2 (HER2)-status can be identified on a proteomic level across different cancer types suggesting that HER2 overexpression may constitute a unique molecular event independent of the tumor site[65].
