Analysis of metastasis related gene in melanoma cells

We show that highly metastatic mouse melanoma B16/BL6 cells express less Gal-3 than B16 cells with a lower metastatic potential. We found that overexpression of Gal-3 in melanoma cells in fact suppresses metastasis. In contrast, knocking out Gal-3 expression in cancer cells promoted cell aggregation mediated through interactions with platelets and fibrinogen in vitro, and increased the number of metastatic foci in vivo. Overall design: We search for metastatic related gene in melanoma cells. Cells were removed in culture dish and total RNA was extracted from cells using Rneasy-plus mini kits. We compared the gene expression of B16 cells and B16/BL6 cells.
