Adiposity Clinical Trial
Official title:
The Role of Estrogen in Adipocyte Remodeling Following Surgical Menopause
The overarching aim of this study is to assess the downstream effects of abrupt estrogen deficiency in women undergoing elective bilateral oophorectomy by studying: 1. the rate of in vivo adipogenesis in the subcutaneous abdominal (scABD) and subcutaneous femoral (scFEM) adipose tissue depots following bilateral oophorectomy surgery using an innovative (and tested) 8-week incorporation of stable isotope (deuterium; 2H) administered in the form of heavy water (2H2O) to endogenously label adipose tissue DNA; 2. the changes in expression of subcutaneous adipose tissue genes and proteins specific to adipocyte expansion and function; extracellular matrix remodeling and fibrosis; and inflammation in the scABD and scFEM depots before and after elective bilateral oophorectomy.
This is a cross-sectional study that will enroll up to 10 women undergoing laparoscopic, elective bilateral oophorectomy at a local hospital in Baton Rouge, LA. Women will complete 7 study visits over 3 months; a single screening visit to assess eligibility, a pre-bilateral oophorectomy visit for imaging and adipose tissue biopsy collection, and 5 post-bilateral oophorectomy visits to "dose", maintain compliance and subject retention, and perform follow-up imaging and adipose tissue biopsy collection for outcome measures. ;
