Abstract
Abstract
Objective. Thyroid hormones play an important role in the development and maturation of the central nervous symptom and their failure in the prenatal period leading to an irreversible brain damage. Their effect on the brain of adult, however, has not been fully studied. With the discovery of neurogenesis in the adult brain, many recent studies have been focused on the understanding the basic mechanisms controlling this process. Many neurogenesis regulatory genes are not only transcribed but also translated into the blood cells. The goal of our study was to analyze the transcriptional activity of neurogenesis regulatory genes in peripheral blood cells in patients with thyroid pathology.
Methods. The pathway-specific PCR array (Neurotrophins and Receptors RT2 Profiler PCR Array, QIAGEN, Germany) was used to identify and validate the neurogenesis regulatory genes expression in patients with thyroid pathology and control group.
Results. The results showed that GFRA3, NGFR, NRG1, NTF3, NTRK1, and NTRK2 significantly decreased their expression in patients with autoimmune thyroiditis with rising serum of autoantibodies. The patients with primary hypothyroidism, as a result of autoimmune thyroiditis and postoperative hypothyroidism, had significantly lower expression of FGF2, NGFR, NRG1, and NTF3. The mRNA level of CNTFR was markedly decreased in the group of patients with postoperative hypothyroidism. No change in the ARTN, PSPN, TFG, MT3, and NELL1 expression was observed in any group of patients.
Conclusion. The finding indicates that a decrease in thyroid hormones and a high level of autoantibodies, such as anti-thyroglobulin antibody and anti-thyroid peroxidase antibody, affect the expression of mRNA neurogenesis-regulated genes in patients with thyroid pathology.
