The reason behind the ineffectiveness of amoxicillin. Case summary: David was bitten by a tick which resulted in a boil on his left shoulder. Though it was not painful still he went to primary care physician who prescribed him amoxicillin for the boil. After three days, he started to feel much worse.

Question

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?

Summary Introduction

To explain:

The reason behind not showing infection in antibody test.

Case summary:

After three days of David’s visit to primary care physician, he developed high fever, muscle pain, fatigue, headache and rashes over his entire body. His physician suspected Rocky Mountain spotted fever and ordered test using Rickettsia rickettsii.

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.
