ALKBH8 contributes to neurological function through oxidative stress regulation.

ABSTRACT: Transfer RNA (tRNA) modification is essential for proper protein translation, as these modifications play important roles in several biological functions and disease pathophysiologies. AlkB homolog 8 (ALKBH8) is one of the nine mammalian ALKBH family molecules known to regulate selenoprotein translation through the modification of the wobble uridine (U34) in tRNA; however, its specific biological roles remain unclear. In this study, we investigated the role of ALKBH8 using Alkbh8-knockout (Albkh8^-/-) mice, which were observed to have reduced 5-methoxycarbonylmethyluridine (mcm5U) and (S)-5-methoxycarbonylhydroxymethyluridine levels; notably, the mcm5U level was partially compensated only in the brain. The results of the novel object recognition test showed reductio
