Abstract

Over 700 polypeptide spots could be detected by two-dimensional electrophoretic analyses of membranes prepared from the murine AKR fibroblastic cells. Out of this abundance of polypeptides, only 9 polypeptide spots were found to be differentially expressed between the untransformed AKR-2B cells and their methylcholanthrene-transformed counterparts, the AKR-MCA cells. Treatment of the untransformed AKR-2B cells with transforming growth factors, prepared from the serum-free conditioned medium of HCT 116 MOSER human colonic carcinoma cells, induced the altered expression of 6 of these polypeptides which paralleled the electrophoretic profile of their permanently transformed counterparts, the AKR-MCA cells.
