The CIwt values indicate that OP449 and dasatinib synergistically reduced the viability of SH-EP, SK-N-SH, NB69, and GI-M-EN but not of SK-N-AS MYCN non-amplified NB cells (Figure 7A) and synergized in NLF and SK-N-BE(2)-C but not in IMR5, LAN5, and IMR32 MYCN-amplified NB cells (Figure 7B). Here, MYCN is linked to neuroblastoma.
