Outline of Final Research Achievements |
We have developed maternal undernutrition model, in which interaction with fetal GAD67 deficiency (GAD67+/GFP) was observed. That was, in contrast to dams, ACTH and CORT increments were significant in heterozygotes. Since WNK3 kinases is an essential element in the signaling cascade regulating Cl- concentrations after salt intake, we have used a WNK3 KO mice and examined membrane properties. Loss of WNK3 activity significantly reduced neuronal excitability, as evidenced by hyperpolarized resting membrane potential, decreases in input resistance and membrane time constant, and a resulting increase in the threshold current for action potential generation. We examined GAD67+/GFP pups underwent prenatal stress, which showed impaired neurogenesis of parvalbumin-positive GABAergic neurons as well as behavioral abnormality. We found multiple genes related to neurogenesis and/or neural migration were either hyper-methylated or hypo-methylated in GAD67+/GFP underwent prenatal stress.
