C-erb B-2 amplification in cystic renal disease

Abstract:

C-erb B-2 amplification in cystic renal disease. Gene amplification (overexpression) of c-erb B-2 was tested in a variety of cystic renal diseases, renal cell neoplasms (adenomas and carcinomas) and end stage kidneys without cysts C-erb B-2 encodes a receptor-like protein that shares homology with, but is distinct from the epidermal growth factor (EGF) receptor. A monoclonal antibody that immunoprecipitates a protein of approximately 185 kD from a lysate of NIH/3T3 cells transfected with the c-erb B-2 gene was utilized for testing. Simple renal cysts, cystic renal dysplasia, autosomal recessive polycystic kidney disease (ARPKD), and non-cystic, essentially normal kidneys failed to show c-erb B-2 overexpression. In contrast, autosomal-dominant polycystic kidney disease (ADPKD), acquired (dialysis-associated) cystic disease (ACD), non-cystic end stage kidneys and renal cell neoplasms revealed overexpression …
