Annotation description:Results:

-Literal: "Western blots showed that, unlike classical synaptic markers such as SynGAP and Homer1, these hnRNPs were present but not enriched in PSD fractions (Fig. 5A). West-
ern blots for postsynaptic (PSD95) and presynaptic (SV2) mark- ers confirmed that we had isolated an enriched PSD fraction (Fig. 5A). To confirm our SILAC results, we performed Western blots for several proteins in PSD fractions isolated from cultured cor- tical neurons stimulated with cLTP BDNF or inhibited with TTX (Fig. 5B). These immunoblots confirmed the SILAC pre- dicted results (Fig. 5B, arrows), showing that hnRNPs M, D, G, and A2/B1 accumulated in PSDs after cLTP BDNF treatment, while SynGAP and homer1 were decreased at PSDs in response to this stimulation (Fig. 5 B, C). No changes in abundance were de- tected for PSD95 or FMRP (FMRP was barely detectable in the PSD fraction; Fig. 5B,C). Using immunocytochemical analysis, we found that hnRNPs G, M, D, and A2/B1 were present in the nucleus (data not shown), as well as in neuronal dendrites and dendritic spines where they colocalized with PSD95 (Fig. 5D). Moreover, using image quantitation, we found that cLTP BDNF resulted in an increase in the colocalization of hnRNPs M, A2/B1, G, and D with PSD-95, which further confirmed our bio- chemical analysis and SILAC results (Fig. 5E)."
