Our analyses did not reveal any evidence that expression levels for any other pair of proteins are correlated across or within tumor types (all P>0.14), that mean MET and P-MET staining indices are different between tumors harvested from intact and castrate animals, or that mean MET and P-MET staining indices differ significantly between LuCaP xenografts that display a high and low response to castration; see Figure S2C. Here, MET is linked to neoplasm.
