Identification of genes differentially expressed in B16 murine melanoma sublines with different metastatic potentials.

Two isotypes of murine nm23/nucleoside diphosphate kinase, nm23-M1 and nm23-M2, are involved in metastatic suppression of a murine melanoma line.

A series of sublines of a murine melanoma B16 of C57BL/6 origin were established and examined regarding their metastatic capacity and expression of nm23. The number of pulmonary metastases developed by these sublines was inversely correlated with the expression of two isotypes of nm23, nm23-M1 and nm23-M2. The cDNAs of nm23-M1, nm23-M2, and a combination of both were transfected into the highly...

Use of Mycobacterium vaccae (SRLI72) as an Immunomodulating Agent in Association with Murine Melanoma Model B16-F10

Carbohydrate chain analysis by lectin binding to electrophoretically separated glycoproteins from murine B16 melanoma sublines of various metastatic properties.

Cellular glycoprotein carbohydrate chains of B16 melanoma sublines of various metastatic colonization capacities were analyzed by polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate and direct lectin staining, combined with chemical modification of carbohydrate chains in situ. For these studies, we utilized B16 sublines selected for low (B16-F1) or high lung (B16-F10), ...

Potential for Melanoma Metastasis Correlates with Melastatin Down-Regulation of the Novel Gene

We have used differential cDNA display to search for genes whose expression correlates with an aggressive phenotype in variants of the B16 murine melanoma line, B16-F1 and 1516-1 10. This analysis identified a novel gene, termed melastatin, that is expressed at high levels in poorly metastatic variants of B16 melanoma and at much reduced levels in highly metastatic B16 variants. Melastatin was ...

Down-regulation of the novel gene melastatin correlates with potential for melanoma metastasis.

We have used differential cDNA display to search for genes whose expression correlates with an aggressive phenotype in variants of the B16 murine melanoma line, B16-F1 and B16-F10. This analysis identified a novel gene, termed melastatin, that is expressed at high levels in poorly metastatic variants of B16 melanoma and at much reduced levels in highly metastatic B16 variants.
