MYCN and neuroblastoma: This study investigated three CDKis (abemaciclib, fadraciclib, and dinaciclib) alone or combined with retinoic acid (RA) to assess the effects on morphology, growth, gene expression, and the induction of immunogenic cell death in NB cell lines with (LAN-1 and CHLA-90) and without (CHLA-172) MYCN amplification.
