RYR1 and neuroblastoma: Of particular interest, we showed that dantrolene-induced lowering of RyR-mediated Ca2+ release leads to the reduction of βAPP cleavage by β- and γ-secretases and decreases both intracellular and extracellular Aβ load in wild type βAPP- or βAPPswe- overexpressing neuroblastoma cells as well as in primary cultured neurons derived from Tg2576 mice brain.
