Summary Introduction

To interpret the data: To find the abnormal activity of pituitary or adrenal gland in a patient who used dexamethasone drug.

Concept introduction:

The adrenal cortex acts through the endocrine system under the stressful conditions, such as reduced level of blood sugar, volume and pressure. It stimulates the hypothalamus to secrete the releasing hormone.  Then the releasing hormone stimulates the secretion of adrenocorticotropic hormone (ACTH) from the anterior pituitary. From the pituitary ACTH reaches the adrenal cortex through blood circulation and stimulates corticosteroids secretion. Two types of corticosteroids found in humans namely, glucocorticoids (cortisol) and mineralocorticoids. Glucocorticoids or cortisol activates glucose synthesis from protein are also involved in the breakdown of proteins into amino acids in muscles.

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.
