I was doing a bit of reading on how hormones can alter gene function and I found some amazing stuff I thought would be worth sharing. The lipid-soluble hormones such as steroids, vitamin A, and the thyroid hormone are the ones that react based on gene activity. These particular hormones are circulated through our bloodstream and contain binding proteins similar to that of DNA. This is why and how steroids can make such huge changes to the human body that are otherwise just not attainable.
