Summary Introduction

To determine:

The reason for an increase in the number of Pertussis cases in the United States since 1970, even after the availability of an effective vaccine.

Introduction:

Gram negative anaerobic bacterium, Bordetella pertussis, of the shape that is intermediate between roundly and rod-like, causes a disease called pertussis, known commonly as whooping cough. It disrupts the working of “ciliated epithelial” cells found in trachea and imparts the disease with the help of some toxins and molecules for adhesions. It is generally diagnosed in very young children up to 5 years of age, by observing symptoms of cough and can be mistaken as common cold.

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.
