To this end, we analyzed our panel of four MYCN-amplified (SK-N-BE, IMR-32, NMB, CHP-134) and four MYCN-non-amplified human NB cell lines (GI-ME-N, SK-N-AS, SK-N-FI, SH-SY5Y) that were exposed to increasing concentrations of UNC or BIX (figure 3A, B). This evidence concerns the gene MYCN and neuroblastoma.
