In the past 4 years, my laboratory has been funded from the National Institutes of Health and American Heart Association. Congenital Anomalies of the Kidney and Urinary Tract (CAKUT) are a major cause of morbidity in children, constituting approximately 20~30% of all anomalies identified in the prenatal period. CAKUT plays a causative role in 30~50% of cases of end stage renal disease (ESRD) in children, and predisposes to the development of hypertension and other renal-cardiovascular diseases in patients that survive to adolescence and adulthood.

Therefore, CAKUT poses a significant economic burden on health care systems related to the patients' lifelong costly therapeutic needs. The long-term goal of our research program is to uncover the epigenetic mechanisms, especially histone acetylation and deacetylation, responsible for CAKUT. Our study will provide new insights into the epigenetics of kidney development and will open new avenues to novel strategies for the prevention and treatment of CAKUT and its associated renal-cardiovascular diseases, through pharmaceutical agents that target epigenetic modifiers. Such epigenetic drugs are already in clinical use or under investigation for the treatment of cancer as well as other. Ongoing projects in the lab are:
