SCG3 and neoplasm: In addition to potential new diagnostic markers (SCG2, SCG3, DDC, MAOA, NEFM, CLDN4, PEROX2), genes critical in the processes of tumour invasion, progression and metastasis (MME, STAT3, DCBLD2, S100A10, CD9, S100A8), tumorigenesis (BEX1, TMEPAI, FOSL1, RAB32) and drug-resistance (ABCC6, GSTP1) were identified, as well as several genes with hitherto unknown functions.
