Research Interests

Preeclampsia (preE) is a systemic and hypertensive pregnancy disorder, which occurs in 3 to 10% of all gestations—accounting for approximately 60,000 maternal deaths per year worldwide. PreE is characterized by the de novo onset of hypertension and proteinuria in pregnancy. The triggers of this condition remain elusive, and pathogenic mechanisms remain ambiguous, resulting in a failure to develop specific screening, preventive, and treatment strategies.

Dr. Uddin’s lab focuses on translational research in maternal fetal medicine especially hypertension during pregnancy. The long-term goal of his lab is to determine the pathogenesis and molecular signaling in hypertension during pregnancy (preE). The potential significance of his research is that successful completion may identify molecular therapeutic targets may be identified to effectively treat preE. He is using animal models (rodents and small monkey species), several human cell lines, and patients for his research.

Research Topics 

Studies on the (pro) renin and its Receptor Associated Novel Renin-Angiotensin System and Placental Perfusion in Preeclampsia: preE affects the placenta which releases substances into the circulation that affect the mother's kidney, liver, and brain. It often results in premature delivery of the baby. Dr. Uddin is looking at the renin-angiotensin system (RAS) in preE, specifically, (pro)renin and its receptor, in the dysregulation of circulation through the uterine-placental circulation during the preE process. In evaluating the function of RAS, (pro)renin, and (pro)renin receptor in a rat model of preE, Dr. Uddin found that the utero-placental RAS was activated and the maternal circulatory RAS was suppressed. However, both the utero-placental receptor and circulatory levels of (pro)renin are increased in these rats. He proposes the hypothesis that (pro)renin receptor-mediated activation of RAS leads to an alteration placental circulation reducing the exchange of oxygen and nutrients in the placenta. His overall goal is to understand the involvement of (pro)renin and its receptor in the cause of the altered extent and timing for regulation of perfusion (the passage of fluids)  through the maternal-fetal unit in the pathogenesis of preE. These studies are intended to provide new evidence that (pro)renin and its receptor play key roles in dysregulation of perfusion and point to promising new therapeutic targets.

Preeclampsia in the Owl Monkey Model to Understand the Pathogenesis: A class of endogenous cardiotonic hormones that can trigger preE in rodents and is increased in patients with preE. In order to test the safety of agents that may block the effects of these agents without harming mother or developing fetus, a species with more similarity to humans than rats must be tested first. One type of monkey species, the owl monkey, a small neotropical monkey from South America, is sensitive to agents and mechanisms that produce increased blood pressure. There are good breeding populations of the monkey in research facilities in central Texas. Previous work by Dr. Uddin and others supports the novel hypothesis that cardiotonic hormones might also produce preE in nonhuman primates using a specific molecular pathway that can be blocked in cultured cells by inhibitors. These studies will examine whether these agents and this mechanism for preE pathogenesis can be demonstrated for the first time in a primate species and whether such treatments are safe to use in pregnancy. 

Evaluate potential linkage between the risk of developing preeclampsia and the presence of diabetes in pregnant patients or the development of gestational diabetes: The concept is that poor glucose regulator control may stimulate one of more mechanisms of cells involved in the vascular remodeling during implantation and placental development, so that pathways leading to vascular compromise are stimulated. The focus of the studies used to develop these risk factor assessments was pooling results from a meta-analysis of many studies of patients with and without preE symptoms.  Based on some preliminary work in our lab, we suspect that elevated glucose levels in pregnancy may stimulate a cascade of vascular development that will predispose to development of placental vascular compromise. Under such conditions, vascular responses can trigger preE pathways. Therefore, we propose to obtain epidemiologic information from a large patient population with subsets of patients who become pregnant who also have pre-existing diabetes and patients who develop gestational diabetes in ethnic groups with high frequencies of both diabetes and preE in pregnancy.

Dr. Uddin’s translational research group consists of basic and physician scientists including medical students, residents, fellows and research associates. Prospective postgraduate and medical students are encouraged to contact Dr. Uddin if interested in this area of research.
