Summary Introduction

Introduction:

The thyroid gland consists of two lobes; it is the largest (weighs about 25 grams) adult endocrine gland. The isthmus connects the two lobes of the thyroid gland.  The thyroid is located at the neck, adjacent to the trachea, and beneath the larynx. It appears in a butterfly shape and is covered around the trachea. It is composed of thyroid follicles that are covered by follicular cells. The follicular cells secret thyroid hormones (TH) such as triiodothyronine (T3) and thyroxine (T4). The thyroid gland releases TH into the bloodstream. Thyroid hormones act by binding to their thyroid hormone receptors (TR), which is a superfamily of nuclear receptors. TR encoding genes are classified into α (TRα) and β (TRβ). Thyroid stimulating hormone (TSH) regulates hormones’ (T3 and T4) secretion from the thyroid. TH raises the metabolic rate by promoting the adequate supply of blood and oxygen. Also, TH increases the heart rate and respiratory rate, and is involved in the breakdown of carbohydrates and fats to provide energy. TH regulates appetite, alertness, the secretion of the growth hormone, body growth, reproduction, and the circulatory system. Abnormal secretion of thyroid hormones may cause thyroid problems.

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb?  Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
