- Proteomic analysis of tissues from the fetal compartment of term placentas has revealed a molecular network of the VEGF receptor 2 (VEGFR2) that could intersect the VEGFR2 signal transduction pathway to support fetal growth and possibly labor.
- Our focus is on solubilized membrane proteins that associate with VEGFR2. A new enzymatic reaction of VEGFR2 to form nucleoside polyphosphates may synergize with membrane and soluble receptors, e.g. purinergic receptors P2Y, to regulate vascular tone and contractions. We correlate clinical data of normotensive and preeclamptic patients with new protein-protein associations of membrane and soluble proteins in the placenta hoping to uncover new regulators of placental vascularization/angiogenesis and of labor.
- Proteomic methods are used to discover protein networks regulating leiomyoma growth in women and in our guinea pig model, and to optimize our cervical mucus peroxidase test for a 3-5 day prediction of ovulation in women.
