In this study we evaluated c-kit, VEGFA, and MYC gene expression level in seven neuroblastoma stable cell lines: SK-N-SH, SK-N-BE, SK-N-AS, SH-SY5Y, Kelly, IMR-32, and LAN-1. Expression levels of these genes can serve as diagnostic factors of cancer progression, and proteins encoded by these genes are promising targets for neuroblastoma treatment. SH-SY5Y and SK-N-AS cells have highest MYC expression and the same VEGFA expression, although SH-SY5Y has 10 times higher c-kit expression than SK-N-AS cells. Both IMR-32 and LAN-1 cells have low MYC expression level, but differ in c-kit expression, IMR-32 has significantly higher c-kit expression, than any other neuroblastoma cell line. LAN-1 on the other hand has the highest VEGFA expression. These data suggest that MYC, c-kit, and VEGFA genes can play different roles in development and progression of neuroblastoma depending on other activated molecular mechanisms in malignant cells.
