| abstractText | Catechol-O-methyl transferase (COMT) methylates catechols, such as L-dopa and dopamine, and COMT deficient mice show dramatic shifts in the metabolite levels of catechols. Increase in catechol metabolite levels can, in principle, lead to oxidative stress but no indices of oxidative stress have been reported in COMT-knockout (KO) mice [Forsberg MM, Juvonen RO, Helisalmi P, Leppanen J, Gogos JA, Karayiorgou M, et al. Lack of increased oxidative stress in catechol-O-methyltransferase (COMT)-deficient mice. Naunyn Schmiedebergs Arch Pharmacol 2004;370:279-89.]. Here we perform a proteomic based analysis of the livers of COMT-KO mice in search for potential compensatory mechanisms developed to cope with the effects of disrupted catechol metabolism. We found sex specific changes in proteins connected to stress response. Our results show that alterations in protein levels contribute to the homeostatic regulation in the liver of COMT deficient mice. |
