Abstract:
Until recently, observational studies suggested a decreased risk of cardiovascular disease, osteoporotic fractures, cognitive decline and colon cancer with the use of hormone replacement therapy (HRT). Recent randomized controlled trials have failed to show a protective effect of HRT in reducing the risk of coronary artery disease and instead have revealed an increased risk of heart disease, stroke, invasive breast cancer and venous thromboembolism, but a decreased risk of colorectal cancer and osteoporotic fractures. In this article we review the current evidence of the risks and benefits of HRT.

Hormonal Regulation
Target Cell Response to Hormones
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...
