Effect of Fabomotizole on Brain Gene Expression in MR Rats in the Open Field Test

Selective anxiolytic fabomotizole (Afobazol®) has affinity for the Sigma-1 chaperone receptor site, quinone reductase 2 (NQO2) and MAO-A regulatory sites, and melatonin receptor type 1 (MT₁ receptor). The analysis of the effect of fabomotizole on the gene expression profile in the brain of MR (Maudsley Reactive) rats was carried out when modeling emotional stress in the open field test. A change in the expression of 14 genes was found, the results of the functional annotation of which showed that the mechanisms of action of fabomotizole may be associated with the regulation of translation of proteins (Rpl5, Rpl15, Ncl, and Ybx1), synaptic functions (Cplx2, Dlg4, Syngap1, Add1, Rab8b, Klc1, and Chn1), and cellular metabolism (Akr1d1, Bcat1, and Pkm).
