GRASLND and melanoma: Interestingly, all differentiated melanoma cell lines, such as 501-mel, SK-MEL-239, Ma-Mel-86c and Ma-Mel-61a, expressed significantly higher GRASLND levels in contrast to all dedifferentiated, mesenchymal-like and AXLhigh cell lines SK-MEL-147, C8161, WM1361a and Ma-Mel-86a (Supplementary Tables S4–S6).
