Development And Application Of A Novel Ultrasensitive LC-MS Estradiol Assay

Funding Amount
$240,400.00
Summary
This project will develop a new ultrasensitive method using liquid chromatography-mass spectrometry to measure extremely low level of circulating estrogens in the bloodstream especially in mice. This will allow for the first time the ability to study the natural regulation of fertility in mice and other sub-primate mammals for which the present assay methods are not adequate.
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

Funding Amount

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.
