Sex Hormones And Heart Disease In Older Women Study (The SHOW Study)

Summary
Cardiovascular disease (CVD, heart disease and stroke) is the leading cause of death in women aged 65 and over. Counter-intuitively, androgens may be as, or even more important, than estrogens in determining CVD risk and all-cause mortality in women, but this is yet to be verified. We will document blood levels of androgens in women aged 70+ and determine whether androgens are associated with CVD and death in this large cohort of elderly well women.
Progesterone Regulation Of Epithelial Expansion In The Normal Human Breast

Summary
The ovaries play a pivotal role in breast cancer. Progesterone increases breast cancer risk, and this is likely to be a subversion of its role in the normal breast, which is to participate in the normal expansion of the epithelial cells during the menstrual cycle, but how it does this is unknown. We will explore how progesterone influences cell types in the breast similar to those that become cancerous. This will uncover potential targets for prevention and treatment.
Sex Steroids Modulate The Neuronal Control Of Bone Formation

Summary
It is well recognised that changes in sex hormones are pivotal to the development of osteoporosis in both men and women. Our group has been instrumental in identifying a novel and powerful system regualting bone mass and strength by neural activity. Recent findings indicate critical interactions between these two pathways in the control of bone formation. Greater understanding of these interactions could lead to therapies capable of controlling this extremely common disease.
