| Research Abstract |
Recent epidemiological studies suggest that the environmental concomitants such as phenols, dioxins, or organochloride pesticides are associated with neurodevelopmental disability including LD, ADHD and autism. The present study tried to elucidate the neurological and endocrinological function of ERR (alpha, beta, gamma) that is one of target molecules for those compounds. It was revealed that all the subtypes of ERRs were expressed in several hypothalamic areas (AVPV, MPOA, VMH) which are crucial for reproductive endocrine function under the control of estrogen receptor (ER) alpha. Molecular studies indicated that ERRbeta reduces the subnuclear mobility of ERalpha and represses its transactivity on the estrogen-response element. ERRgamma was strongly expressed in reticular thalamic nucleus and substantia nigra reticular part of neonatal rat. These results suggest that ERRs contribute to the regulation of neuroendocrine function and the development of sensorimotor control in the brain.
