Dr. Lu is a Principal Investigator and Associate Professor of Medicine, Pathology, and Laboratory Medicine at Boston University and Boston Medical Center. He is also the Primary Mentor for medical students, graduate students, undergraduate students, fellows, and postdocs in the Nephrology Section Department of Medicine. Dr. Lu’s laboratory focuses on basic and translational research in nephrology and genetics, including kidney development, congenital anomalies of the kidney and urinary tract (CAKUT), podocyte biology and injury, pericyte biology, and renal fibrosis, ROBO/SLIT and ZEB signaling, pre-clinical animal models of kidney disease, as well as the discovery of new biomarkers, artificial-intelligence-based pathology tools to improve diagnosis and clinical trials and novel drug development for chronic kidney disease. His significant scientific contributions in the field of nephrology and genetics include: (1) discovering ROBO2 as one of the causative genes for CAKUT and VUR (OMIM 610878), (2) identifying SLIT2/ROBO2 signaling as a novel drug target for proteinuric kidney diseases, which negatively regulates nephrin signaling, nonmuscle myosin IIA signaling and podocyte adhesions in podocyte biology and injury, (3) creating the first animal model for autosomal dominant polycystic kidney disease (PKD1), and (4) discovering ZEB2 as one of the causative genes for glomerulocystic kidney disease and its essential role in kidney stromal progenitor cell differentiation and renal fibrosis. In recognition of his seminal contribution to the development of a potential new drug for chronic kidney disease in collaboration with Pfizer, Dr. Lu was named the 2019 Boston University Innovator of the Year, an award bestowed annually on a faculty member who “translates his/her world-class research into inventions and innovations that benefit humankind”. Dr. Lu is the Chair of the Core Oversight Advisory Committee in the Department of Medicine, a Co-Director of the BU Clinical and Translational Institute (CTSI) R-Award Grant Writing Workshop, and a voting member of the Boston University Institutional Biosafety Committee (IBC). He is also a fellow of the American Society of Nephrology and the International Society of Nephrology. Dr. Lu is an Academic Editor of the scientific journal PLOS ONE and a member of the NIH grant review study sections of various grant mechanisms, including R01, R21, R03, F32, RC1, RC2, RC4, R13, R15, U01, UH2, UH3, U24, U54, P01, P20, and P50.
The primary research interests of Dr. Lu’s laboratory focus on basic and translational research in four scientific areas. 1) Molecular genetics of the kidney and urinary tract development and congenital anomalies of the kidney and urinary tract (CAKUT). 2) Biological function and disease mechanism of kidney and urinary tract congenital disability genes and their roles after birth in chronic kidney diseases. 3) SLIT/ROBO and ZEB signaling in kidney and urinary tract development and disease. 4) Discovery and development of new biomarkers, novel drug targets, and therapeutics for patients with chronic kidney and eye diseases.
Congenital anomalies of the kidney and urinary tract (CAKUT) is a complex congenital disability with a diverse phenotypic spectrum, including kidney anomalies (e.g., renal agenesis, multicystic dysplastic kidney, hydronephrosis) and ureteric anomalies (e.g., vesicoureteral reflux, obstructive uropathy) (Ref 1, 2). CAKUT is also the leading cause of chronic kidney disease and kidney failure in children and young adults under 40 (Ref 3).
Dr. Lu’s basic and translational research program has adopted combined human and mouse molecular genetics approaches to identify developmental genes important in kidney and urinary tract development and pathogenesis of CAKUT. The first human molecular genetics approach is to study patients with CAKUT and apparent genetic defects using gene mutations, genomic imbalances, and chromosomal rearrangements as signposts to identify disease-causal genes (reverse genetics) (Ref 2). After that, molecular identification and analysis of disease genes and mutation studies in affected patients with a familial pattern of CAKUT will be carried out (forward genetics) (Ref 2, 4). The second approach is to study temporal and spatial expression patterns of disease genes in human and mouse models. Concurrently, the knockout and transgenic mouse models of human disease genes will be generated and examined to recapitulate the human disease phenotype. Once these disease genes (e.g., ROBO2, SLIT2, ZEB2) are identified and animal models are created, a multidisciplinary research approach will be taken to gain further mechanistic insights (in vivo and in vitro) on the role of these genes in normal and abnormal developmental processes of the kidney and urinary tract, and on the pathogenesis of CAKUT and kidney injury after birth (Ref 5-9). The multidisciplinary research approach includes pre-clinical animal models, patient samples, and biomarker studies using different new biomedical technologies and research techniques in molecular genetics, developmental biology, protein biochemistry, molecular biology, pathology, pharmacology, and computing & data sciences. Dr. Lu’s basic and translational research program connects the bench and bedside. It has generated new knowledge of disease mechanisms of CAKUT and kidney disease after birth, which facilitates the discovery of novel drug targets and therapeutics for patients with chronic kidney disease (Ref 7-10) (https://www.eurekalert.org/pub_releases/2016-11/bumc-rip_1111516.php & https://www.eurekalert.org/pub_releases/2020-05/buso-rsn050420.php).
Current research projects in Dr. Lu’s lab include:
1). Molecular genetics of kidney and urinary tract development and congenital anomalies of the kidney and urinary tract (CAKUT).
2). Podocyte biology & injury in podocytopathy and nephrotic syndrome. Pericyte biology & injury in renal fibrosis.
3). Discover new drug targets and novel therapeutics for patients with proteinuric kidney diseases & neovascular retinal eye diseases.
4). Development of new biomarkers and artificial intelligence-base pathology tools for improved diagnosis and clinical trials of kidney and eye diseases.
Dr. Lu’s research program is supported by grants from the government (e.g., NIH, DOD), foundations (e.g., NKF, MOD), industry (e.g., Pfizer), and BU/BMC awards (e.g., CTSI, Ignition Award).
