Abstract

Classic multidrug resistance is mediated by a P-glycoprotein. Using monoclonal antibody C219 (MAb C219) in an immunohistochemical study, we found high levels of putative Golgi P-glycoprotein in normal columnar and transitional epithelium in subpopulations of patients with specific blood types. For example, Golgi staining was present in blood type A patients in 46% of normal colon samples (N = 21) and 88% of normal ureter samples (N = 17). In comparison, Golgi staining was present in blood group O patients in only 6% of normal colon samples (N = 34) and in 0% of normal ureter samples (N = 19). The association of MAb C219 Golgi staining with blood type A and lack of Golgi staining with blood type O was statistically significant in normal colon (P = .001) and normal ureter (P < .0001). Inappropriate hyperexpression of P-glycoprotein was frequently found in colon carcinomas. Additional evidence that Golgi MAb C219 reactivity represents P-glycoprotein is presented. This includes (1) immunostaining of Golgi with two anti-P-glycoprotein MAbs, C219 and JSB-1, and (2) experiments in which Mab C219 Golgi reactivity was blocked by preincubation of MAb C219 with a specific P-glycoprotein epitope-containing peptide. The high degree of association of Golgi P-glycoprotein with blood type A may suggest a role for P-glycoprotein in processing or trafficking of specific blood group antigens.
