Genetic Correlates and Pathophysiology of Hyperthyroidism: An Overview of salient aspects

Introduction
Disturbances in thyroid haemostasis can occur at the level of the pituitary gland, the thyroid gland itself or in the periphery. By definition, hyperthyroidism refers to disorders in which the principal abnormality is the overproduction of thyroid hormones in the thyroid gland. (Elston & Conaglen, 2005) This overproduction can have diverse determinants including auto-immunity, hereditary factors, familial predisposition, and perhaps, some other less understood factors. Regardless of etiology, the result is an increase in transcription in cellular proteins, causing an increase in the basal metabolic rate. The predominant cause of hyperthyroidism is Grave’s disease. Other less common ...

One of the recent studies conducted by scientists from the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden has shown interesting results on the mechanism of brain stem cells proliferation and the conditions necessary for the successful progress in this matter (Max-Planck-Gesellschaft, 2014). By conducting experiments on mice and analyzing the available data, the scientists discovered that extracellular matrix, which is produced by progenitors and the thyroid hormones are both necessary for proper development of the brain.
ECM and thyroid hormones allow the brain to become larger by basal progenitor proliferation. This finding allows the ...

Introduction

Hypothyroidism is a condition mainly characterized by low concentration of serum T4 (thyroxine) hormone. When this happen during pregnancy is known as maternal hypothyroxinemia. Adequate Thyroid hormone (T4) levels are critical during first trimester of gestation when the only source of T4 hormone of the fetus comes from the mother. A deficiency of T4 hormone constitutes a risk factor in the neurodevelopment and growth of the fetus . Severe mental retardation is one of the major conditions observed in children with non sufficient levels of thyroxine (T4) hormone during early fetal developing stages.
It is now well documented, that thyroid hormone ...

Abstract

The body has two main systems that are involved in the maintenance and reestablishment of homeostasis, nervous system and endocrine system. The endocrine system is made up of groups of organs that are involved in the production of chemical messengers known as hormones. Some of the major endocrine glands that are found in a human body include the hypothalamus, pituitary, thyroid, pancreas, pineal, gonad, adrenal, and pancreas glands. Although biological observations that are grounded in the functions of endocrine systems were noted by some of the ancient cultures, the modern understanding of various endocrine glands and the way they produce ...
