Abstract：
:In the study described here we investigated the possibility of an association between the aggressiveness of melanoma and multidrug resistance phenotype by analyzing the expression and activity of P-glycoprotein (Pgp) in two genetically related transplantable hamster melanomas--a melanotic (Ma) and an amelanotic (Ab) form --which differed in aggressiveness and metastatic potential. Flow cytometric analysis of Pgp activity (using a verapamil-sensitive rhodamine R123 exclusion test) as well as Western blotting of cellular lysates showed its preferential (although not very marked) expression in the Ab melanoma cells. The Ab melanoma cells also exhibited a higher proportion of tumor-infiltrating lymphocytes (TIL), mostly of T cell phenotype, that may have reflected a higher immunogenicity of the tumor. In conclusion, Pgp activity appeared to be associated with less-differentiated more aggressively metastasizing melanoma (the Ab variant) although its role in maintaining this phenotype remains to be established.
