An immune IFN-inducible human melanoma-associated glycoprotein Ag, 96-kDa MAA, having preferential distribution on metastases has been defined by mouse mAb CL203.4. To initiate molecular genetic analysis of 96-kDa MAA, the gene encoding the Ag was transfected into mouse B16 melanoma cell clone B78H1. Formation of B78H1-transfectant colonies expressing a surface Ag reactive with mAb CL203.4 in an immunorosetting assay was dependent on addition of chromosomal DNA from human melanoma cells [primary (1 degree) transfer] or from Ag-expressing transfectant cells (2 degrees, 3 degrees, 4 degrees transfer). The mAb CL203.4-reactive species expressed by the transfectant cells is a glycoprotein with a molecular mass 93-kDa, within the range of 93 to 96-kDa observed for the endogenous human Ag. In the presence of tunicamycin, an inhibitor of N-linked glycosylation, both mouse melanoma transfectants and human melanoma cells express a 50- to 51-kDa antigenic species. Human alu family repeat sequences (h-alu) are present in the genomes of 3 degrees transfectant cells. Continued presence of these h-alu after dilution of extraneous human DNA by three cycles of transfection suggests their association with the transferred 96-kDa MAA gene. Use of a selective co-amplification procedure led to transfectant cells' increased expression of 96-kDa MAA and to commensurate increases in their content of presumed 96-kDa MAA gene-associated h-alu. Preferential DNA-mediated transferability of the 96-kDa MAA+ phenotype into B78H1 cells as compared with LMTK- mouse fibroblasts suggests host cell specificity of 96-kDa MAA gene expression.
