Research Abstract |
Thyroid hormone plays crucial role in normal development of nervous system. Insufficiency of thyroid hormone during embryonal, neonatal, or infant periods leads to irreversible deficit in development of nervous systems. It is well known that insufficiency or excess of thyroid hormone also affects brain function in adolescents. Depression and/or Alzheimer's disease-like symptoms have been documented in patients with hypothyroidism. Although several genes regulated by thyroid hormone in nervous systems have been identified, most of these genes are not responsive to thyroid hormone in adult nervous system as in immature nervous system. The present study was, thereby, aimed to identify novel thyroid hormone responsive genes expressed in adult nervous system. For this purpose, mice were rendered hypothyroid by we performed cDNA subtraction using RNA extracted from hippocampus, in which neurogenesis has been documented in mature animals.
