We previously reported that Wistar Kyoto rats, an animal model of depression, have a characteristically abnormal serine metabolism in the brain, i.e., lower serine and cystathionine, which is a metabolite of serine, concentrations in the brain. To explore the mechanism underlying this abnormality, the expression of cystathionine β-synthase and serine(More)
Intracerebroventricular (i.c.v.) injection of kynurenic acid (KYNA) had sedative and hypnotic effects during stress in neonatal chicks. However, its mechanism has not been clarified. KYNA is an endogenous antagonist of the α7 nicotinic acetylcholine (α7nACh) receptor and N-methyl-d-aspartate (NMDA) receptor. Therefore, this study clarified the mechanism of(More)
In the brain of neonatal chicks, tryptophan has a sedative effect, and a part of this effect might be dependent upon its metabolite, serotonin. However, the functional mechanisms have not been fully clarified, since l-tryptophan produces kynurenic acid (KYNA) through the kynurenine pathway. The present study aimed to clarify the effect of KYNA on the stress(More)
Corticotropin-releasing factor (CRF) modulates the activity of the hypothalamic-pituitary-adrenal axis, and has a key role in mediating neuroendocrine effects that occur in response to stressful stimuli. We have recently shown that exposure of neonatal chicks to low-temperature resulted in increased oxidative damage to the brain and i.c.v. injection of CRF(More)
Research has shown that on exposure to low environmental temperature, neonatal chicks (Gallus gallus) show hypothermia and absence of gene transcript enhancement of putative thermogenic proteins, mitochondrial fatty acid transport, and oxidation enzymes. Various behavioral abnormalities may also decrease the thermogenic capacity of low-temperature-exposed(More)
