History of Changes
  Purpose

This project was created to assess sex differences in adipose tissue gene expression in different locations in the body. The primary objectives are to understand:

  1. The mechanisms of differential body fat distribution in men and women
  2. How body fat distribution is affected by reproductive hormones
  3. The mechanisms linking fat distribution to health risks such as diabetes
