Proteomics & Glyco-Proteomic Analysis of Follicular Fluid

To the best of the investigators knowledge, exhaustive characterization of the low and high abundant proteins and glyco-proteins of the Follicular Fluid (FF) has not yet been achieved. Such an analysis may provide critical molecular data on the role of the FF in oocyte maturation and may identify specific changes in the FF proteome of patients with gynecologic problems, such as Polycystic Ovary Syndrome (PCOS). Specific Aims 1. To perform a comprehensive analysis of normal human FF using sensitive mass spectrometry in combination with conventional approaches for proteomic evaluation and using HPLC and Western blot for glyco-proteomic analysis. 2. Characterize differential proteomic and glyco-proteomic patterns of the FF in normal women compared to lean and obese women with PCOS. 3. To supplement the differential proteomic and glyco-proteomic analysis with steroid hormone analysis in all FF samples.
