B7-H3 associated with tumor progression and epigenetic regulatory activity in cutaneous melanoma.

ABSTRACT: B7-H3, a cell surface transmembrane glycoprotein, was assessed for its functional and prognostic role in cutaneous melanoma progression. B7-H3 expression in melanoma cells was shown to be related to specific downstream signal transduction events as well as associated with functional epigenetic activity. B7-H3 expression and prognostic utility were shown by reverse transcription and real-time PCR and immunohistochemistry analysis on individual melanoma specimens and then verified in clinically annotated melanoma stage III and stage IV metastasis tissue microarrays in a double-blind study. B7-H3 messenger RNA expression was shown to be significantly increased with stage of melanoma (P<0.0001) and significantly associated with melanoma-specific survival in both stage III (P<0.0001) and stage
