Goiters are caused by excessive stimulation of the thyroid gland.

a) Explain why an individual with hyperthyroidism may develop a goiter

b) Explain why an individual with hypothyroidism may develop a goiter

Objective 1:

You run a transcriptome analysis and find that Lis1 is a gene that is has a loss-of-function mutation more often in ASD patients compared to non-ASD controls. You would like to understand how this mutation manifests in a rodent model.

1. Please describe what ‘loss-of-function’ means.

              Loss-of-function means that this Lis1 gene’s product (protein) will have less to no function at all. With less function, the gene product will only be partially inactivated, but with complete loss of function it is amorphic.

2. Please describe how you can examine the effects of decreased Lis1 function in mice at the RNA and protein levels.

I need help with the 2nd portion of this question. She is basically asking how you would measure changes in RNA and changes in protein, but I am not sure what the best method would be to do either one of these. Qpcr?

Coronary artery disease is a common type of heart disease and the leading cause of death among both men and women in the United States. In this assignment, you will explore this disease in more detail using the scenario below.

Scenario:
One of your aging relatives is sedentary and smokes cigarettes. Out of concern for his health, you decide to research more about this disease.

To complete this assignment, do the following:

1. Research this disease using a minimum of 2 sources.
2. In a minimum of 2 pages (not counting the references page), address the following:
   • Explain how coronary artery disease develops in the human body.
   • Describe the ways that your relative can prevent the onset of this disease.
   • Explain what treatment options exist if steps to prevent the disease fail.
3. Include a references page at the end of your document, formatted using the APA guidelines, that lists your research sources.
