FTY-720 induces apoptosis in neuroblastoma via multiple signaling pathways.

ABSTRACT: Neuroblastoma (NB) is the most common extra-cranial pediatric solid tumor. High-risk NB is difficult to treat due to the lack of response to current therapies and aggressive disease progression. Despite novel drugs, alternative treatments and multi-modal treatments, finding an effective treatment strategy for these patients continues to be a major challenge. The current study focuses on examining the effects of FTY-720 or fingolimod, a drug that is FDA-approved for refractory multiple sclerosis, in NB. The results showed that FTY-720 regulates multiple pathways that result in various effects on calcium signaling, ion channel activation and cell survival/death pathways. FTY-720 rapidly inhibits TRPM7 channel activity, and inhibited TRPM7 kinase activity, modulates calcium signaling, induces
