pubmed:abstractText |
The epidermal growth factor (EGF) receptor in two colon carcinoma lines and in one vulval carcinoma line tested contains carbohydrate determinants that are recognized by monoclonal antibodies to tumor-associated antigens. These antibodies are directed to sialylated Lea and to difucosylated structures of the Y type. Cell lines which react with these antibodies express these antigens on their surface glycolipids and glycoproteins, including the EGF receptor. These unusual carbohydrates are absent in EGF receptors from normal untransformed cells, and from tumor cells which do not express these specific antigens. Although EGF receptor represents only 0.1-2% of total plasma membrane proteins of antigen-positive carcinomas, it accounts for 20-80% of total protein-associated sialylated Lea/Y type of nonsecreted carbohydrates present in these cells. The results of cell-binding, immunoprecipitation, and Western blot analyses of the antigen-positive carcinomas indicate that sialylated Lea/Y type of antigenicity is intrinsic to the EGF receptors of these cells, and that the antigen is present in receptors from both over-expressing and normal-expressing carcinomas.
