Division of Nephrology

Barasch Lab


The Barasch Lab focuses on the mechanisms of kidney growth and kidney damage. Dr. Barasch’s work began with the identification of a method to generate fully segmented nephrons from renal progenitors (Cell, 1999) and because of this assay, Dr. Barasch has recently defined a novel and critical transcription factor in nephrogenesis and nephron patterning, a Cp2 like factor (JCI, 2014). During this search for growth factors he fourtuitously purified NGAL (Mol Cell, 2002); its expression demonstrated that the first response of the kidney to acute injury was production of an iron chelator for bacteriostasis (Nature Medicine, 2011) by a cell type (interacalated cells) that was not previously thought to play a role in acute kidney injury pathophysiology (JCI 2014). The work not only opened many doors for further inquiry in the response of the kidney to injury, but as a sequel, Barasch introduced the first biomarker of kidney damage to be used clinically (in Europe, Asia; JCI, 2005Lancet, 2005;  Annals of Internal Medicine, 2008; JACC, 2012). Dr. Barasch has been funded continuously by the NIH for the past two decades and is currently funded by two NIH RO1 grants and the March of Dimes. He is also co-Principal Investigator of an NIDDK-sponsored George O’Brien Urology Center (Multi-PI with Drs. Mendelsohn and Gharavi) studying the loss of urinary defense mechanisms as a result of genetic defects in urinary tract formation. He has been a member of the March of Dimes Study Section for 10 years and an ad-hoc reviewer at the NIH and Columbia’s CTSA. Dr. Barasch has hosted more than 30 college and medical, graduate and post-doctoral students in his lab; 7 are now independent scientists, 3 currently hold NIH funding. He also has a leadership role in developing educational programs and career tracks for aspiring clinician scientists. He is the Director of the PhD to MD program, Course Director of Molecular Mechanisms, and Director of the Clinician Scientist Track of House Staff Training in Internal Medicine. Dr. Barasch has received the Bomfalk and the Presidential Awards of Columbia University and recently the Provost Award in novel educational techniques.
