摘要

We have established four cell lines derived from the human KB carcinoma cell line which express high-level multiple drug resistance. One of these lines was selected for resistance to colchicine, one was selected for resistance to colchicine in the presence of the tumor promoter, mezerein, one for resistance to vinblastine, and one for resistance to adriamycin. All of these cell lines are cross-resistant to the other selective agents. The development of multidrug resistance in these cultured human carcinoma cells is associated with a limited number of specific protein alterations revealed by high resolution two-dimensional gel electrophoresis and Western-blot analysis. These protein alterations in multidrug-resistant lines include the decreased prevalence of members of a family of proteins of molecular mass 70,000 to 80,000 daltons, pI 4.8-5.0, the increased synthesis of a protein of molecular mass 21,000 daltons, pI 5.0, in the colchicine-resistant cell lines only, and the increased expression of a 170,000-dalton protein in membrane preparations from all of the resistant cells. The loss of the 70,000- to 80,000-dalton proteins in the multidrug-resistant lines, which can also be demonstrated by immunoprecipitation of these proteins with specific antisera, is associated with a loss of translatable mRNA for these proteins. These studies suggest that only a limited number of protein changes occur in multidrug-resistant cell lines.
