We assayed markers of both mesenchymal differentiation (VIM, PRRX1 and SNAI1) and adrenergic differentiation (NCAM, NF68), but observed no reproducible changes in gene expression, suggesting that GATA3 knock-down only affects proliferation and death, but not differentiation, in neuroblastoma cells. The gene discussed is NCAM1; the disease is neuroblastoma.
