FMR1 and autism: Stable isotope labeling by amino acids in cell culture (SILAC)-based proteomics in Fmr1 knock-out and wild-type cortical neurons resulted in identification of 132 differentially expressed proteins in absence of FMRP, related to changes in synaptic structures, neurotransmission, and dendritic mRNA transport, together with autism- and epilepsy-related proteins [246].
