PTEN and clear cell renal carcinoma: MET amplification is present in renal clear cell carcinoma cases, and protein profiles of amplified and non-amplified cases can be discriminated (sdis = − 0.18; p = 0.0; srand = − 2.0e−5; Src_pY527, Bcl-2, beta-Catenin, PTEN, MAPK_pT202_Y204 are decreased in amplified cases and ACC1, Cyclin_B1, ASNS, ACC_pS79, and Transglutaminase are increased).
