Popis: | AlkB family proteins are enzymes that repair alkylated DNA and RNA by oxidative demethylation. Nine homologs have been identified and characterized in mammals. ALKBH1 is conserved among metazoans including Drosophila. Although the ALKBH1 mouse homolog, Alkbh1 functions in neurogenesis, it currently remains unclear whether ALKBH1 plays a role in neuronal disorders induced by ultraviolet-induced DNA damage. We herein demonstrated that the Drosophila ALKBH1 homolog, AlkB contributed to recovery from neuronal disorders induced by ultraviolet damage. The knockdown of AlkB resulted in not only learning defects but also altered crawling behavior in Drosophila larvae after ultraviolet irradiation. A molecular analysis revealed that AlkB contributed to the repair of ultraviolet-induced DNA damage in the central nervous system of larvae. Therefore, we propose that ALKBH1 plays a role in the repair of ultraviolet-induced DNA damage in central nervous system. Ultraviolet-induced DNA damage is involved in the pathogenesis of xeroderma pigmentosum, and has recently been implicated in Parkinson's disease. The present results will contribute to our understanding of neuronal diseases induced by ultraviolet-induced DNA damage. |
