NEDD9 and melanoma: In contrast, SOX9 expression began to express in a subset of NEDD9+ melanoma cells, which had metastasized to the small intestine and another subset of NEDD9+ cells exhibited SOX10 expression (Fig. 2a, d), whereas we detected co-expression of SOX10, SOX9, and NEDD9 in another patient with intestinal melanomas (Fig. 2b, d).
