Having established that omoMYC/HBpep-SP coacervatesspecifically induce cell death in HEK293 while not in HeLa cells,we asked whether the approach would allow us to detect differencesin the apoptotic induction of omoMYC also in neuroblastoma cell linesestablished from metastatic bone marrow tumors from stage 4 patients.Since omoMYC targets both c-MYC and MYCN proteins, we used SH-SY5Y cells which express c-MYC, and SK-N-BE(2)cells which carry a MYCN-amplification absent inSH-SY5Y cells. Here, MYCN is linked to neuroblastoma.
