Question
Chapter 19, Problem 20PDQ
Summary Introduction
To determine: The relationship between methylation of the glucocorticoid receptor gene and behavioral response to stress.
Introduction: Stress refers to a state or tension. It can be both positive and negative. If stress motivates an individual and enhances his performance, then it is positive. When stress deteriorates the individual’s performance, then it is negative.

Many currently marketed drugs exert their pharmacological effects by binding to ligand-activated transcription factors and modulating gene expression. One example, are various drugs that target the estrogen receptor to treat breast cancer, osteoporosis and post-menopausal symptoms. Below is a ChIP experiment examining the effects of no drug treatment (C), the natural hormone estrogen (E) and the drugs tamoxifen (T) and raloxifene (R) on recruitment of coactivators (SRC-1 and CBP), Histone Deacetylase Complexes (HDACs) and acetylation of histones associated with the C-myc gene. Which of the following statements are correct based on this data (select all that apply)?
Identify the two general functions of the proteins encoded bytumor-suppressor genes.
Describe the steps that need to occur for the glucocorticoid receptor to bind to a GRE.
