The mechanism of tumor promotion is not well understood. We have used the transformable, tumor promotable, mouse embryo fibroblast C3H/10T1/2 Cl 8 cells to study tumor promoter specific changes in protein synthesis and protein glycosylation. Two-dimensional gel electrophoresis showed that 12-O-tetradecanoylphorbol 13-acetate caused a significant increase in the synthesis of five cellular and 34 extracellular polypeptides. One of these polypeptides has tentatively been identified as ornithine decarboxylase. One new polypeptide (p 62, Mr 58,000) was found in the medium of 12-O-tetradecanoylphorbol 13-acetate-treated cells. The amounts of several excreted proteins were enhanced 5-10 fold by 12-O-tetradecanoylphorbol 13-acetate. 12-O-tetradecanoylphorbol 13-acetate interfered with glycosylation both by affecting protein synthesis and also directly with glycosylation. At least 15 polypeptides in the medium and two cellular polypeptides decreased after 12-O-tetradecanoylphorbol 13-acetate treatment. Two of the major polypeptides found in the medium (p 8 and 10, Mr approx. 200,000-220,000) have properties similar to fibronectin, while p 9 and 11 both found in the cellular preparations and in the medium (Mr 180,000 and 150,000) were collagenase sensitive and their synthesis was inhibited by 12-O-tetradecanoylphorbol 13-acetate.
