MK-801-exposure induces increased translation efficiency and mRNA hyperacetylation of Grin2a in the mouse prefrontal cortex.

ABSTRACT: Acute exposure to MK-801, the non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist, induces schizophrenia-like behavioural changes in juvenile male mice. However, the effects of acute MK-801 exposure on brain gene expression at the translation level remain unclear. Here, we conducted ribosome profiling analysis on the prefrontal cortex (PFC) of acute MK-801-exposed juvenile male mice. We found 357 differentially translated genes, with the N⁴-acetylcytidine (ac⁴C) consensus motif enriched in the transcripts with increased translation efficiency. Acetylated RNA immunoprecipitation sequencing revealed 148 differentially acetylated peaks, of which 121 were hyperacetylated, and 27 were hypoacetylated. Genes harbouring these peaks were enriched in pathways
