SYP and neuroblastoma: It was previously shown that, another mitochondrial protein synthesis inhibitor, chloramphenicol prevented neurite outgrowth and synaptophysin increase in C1300 murine neuroblastoma cells [53], reduced neurite length in rat PC12-ND6 cells and the frequency of stage 3 mouse hippocampal neurons [54], and reduced mouse primary cortical neuron differentiation [55].
