Differential expression of SHP2, a protein-tyrosine phosphatase with SRC homology-2 domains, in various types of renal tumour.
SHP2, a widely distributed protein-tyrosine phosphatase with src homology-2 (SH2) domains, is highly expressed in the brain and may play a role in synaptic communications or cellular proliferation. In this study, we examined SHP2 protein expression in 110 renal cell tumours of various histological subtypes, including clear, granular, papillary, chromophobe, collecting duct, and sarcomatoid-type renal cell carcinoma (RCC), and oncocytoma. SHP2 was expressed predominantly in normal distal tubules and collecting ducts, and positivity in various types of renal tumours was as follows: clear cell RCC, 0% (0/77 cases); granular, 7.7% (1/13); papillary, 50% (3/6); sarcomatoid, 0% (0/1); chromophobe, 85.7% (6/7); collecting duct carcinoma, 0% (0/2); oncocytoma, 100% (4/4). Clear and granular-type RCCs showed a very low but positive expression of SHP2. Chromophobe RCC and oncocytoma showed the highest rates and strongest intensities of SHP2 protein on immunostaining. SHP2 may serve as a powerful marker in detecting rare tumours. Estimates of its expression may be useful in histological diagnosis.
