The major goal of my laboratory is to decipher molecular and genetic mechanisms underlying development and diseases of the kidneys and lower urinary tract. Our main hypothesis is that developmentally important genes play a role in congenital malformations, repair and regeneration of organs in acute and chronic diseases, and cancer. To this end we use disease model systems and “omic” technologies and integrate basic science and clinical research. Below are the major ongoing projects.
Investigations of early urogenital development and patterning. Glial cell line-derived neurotrophic factor (GDNF)-RET receptor tyrosine kinase signaling is required for kidney formation (ureteric bud induction), ureter maturation and branching morphogenesis. These events rely on reciprocal interactions between the RET expressing ureteric bud epithelial cells that are also the precursors for the collecting ducts, and the GDNF expressing metanephric mesenchyme. We are using GDNF-RET signaling system as a paradigm to decipher the cellular events (proliferation, cell movements, cell death and cell interactions) and mechanisms during early development of the Wolffian duct, ureteric budding and branching, insertion of ureter into the cloaca and innervation of the urinary tract. Ongoing studies include using novel genetically engineered mice, whole mount 4-D live time-lapse microscopy, population and single cells analysis of defined cell-types to determine the fate of RET-expressing cells in the genitourinary tract, role of RET associated pathways in acute injury and regeneration, and genetic abnormalities in CAKUT patients. These studies will provide insights into pathogenesis, diagnosis and treatment of CAKUT and fundamental knowledge to make new kidneys and ureters.
Discovery of genetic variants associated with kidney disease and their mechanisms of action. In collaboration with pathologists, pediatric nephrologists and urologists we have enrolled several hundred patients from the Midwest region with a spectrum of kidney diseases and collected their serum, plasma, cells, urine and DNA. The goal is to use these resources to discover new biomarkers associated with diagnoses and prognosis, and gene variants associated with disease. Our major focus is currently on CAKUT and glomerular diseases using whole exome or custom targeted exome sequencing and then using model systems in vitro and in vivo to understand causative mechanisms. These studies will identify new causes of CAKUT, and provide novel insights into how developmentally important genes cause these defects, lead to CKD and renal failure.
Mechanisms of acute injury and regeneration. We have implemented various models of acute injury to the kidneys (rhabdomyolysis, ischemia-reperfusion injury, ureteral obstruction) and to the bladder (UTI, chemical toxicity). We are using these in different scenarios to determine how interactions between development genes and environment impact repair, regeneration and function. In the lower urinary tract we are particularly interested in interactions between the peripheral nervous system and epithelial homoeostasis.
