CD44v8-10 and U2AF2 expression levels, which are negatively correlated with CD82 levels, are markedly elevated in primary melanoma compared with dysplastic nevi and further increased in metastatic melanoma.
In fact, KAI1 expression is drastically reduced in primary melanoma compared with dysplastic nevi (P = 1.8×10(-4)) and further reduced in metastatic melanoma compared with primary melanoma (P = 9.4 × 10(-15)).
