Education and Training

Dr. Valeriu Cebotaru received his medical degree from Universitatea de Medicina si Farmacie Carol Davila in Bucharest, Romania. Dr. Cebotaru completed a post-doctoral fellowship at the Johns Hopkins University, clinical fellowship in nephrology at UT Southwestern and a research fellowship in nephrology at Johns Hopkins University. He joined the faculty at the University of Maryland in 2015.


Dr. Cebotaru is an assisstant professor in the department of medicine, division of nephrology. Dr. Cebotaru's research interest is in ADPKD.

Research/Clinical Keywords

Autosomal dominant polycystic kidney disease (ADPKD) is a hereditary disorder that affects 1:500 to 1:1000 people and is characterized by fluid-filled cysts that arise from renal tubules. ADPKD results from mutations in either the PKD1 or PKD2 gene, which encode the gene products polycystin 1 (PC1) and polycystin 2 (PC2), respectively. Histone deacetylase 6 (HDAC6) expression and activity are increased in Pkd1 mutant renal epithelial cells suggesting that it may play a role in cyst formation. We are studying role of PC1, PC2 and HDAC6 in cyst formation in ADPKD.
