Focus on Research: Ion transporters in the kidney (Part 1)

Part 1 of 2


Hui Cai, MD

Dr. Hui Cai, an assistant professor of medicine in the Emory Division of Renal Medicine, studies the regulation of sodium potassium 2 chloride (NKCC) cotransporters in various models of hypertension.

Dr. Cai investigates the role(s) of WNK kinase in the regulation of the NKCC cotransporter and the Maxi K channel in the kidney. His research, which has been supported by NIH and AHA funding, aims to elucidate the molecular mechanism underlying PHA II, also referred to as Gordon syndrome. Gordon syndrome is characterized by hypertension, an excess of potassium, and metabolic acidosis.

Although sodium is essential for healthy bodily functions, too much sodium can be harmful for people with kidney disease, because their kidneys cannot eliminate excess sodium and fluid from the body. As sodium and fluid build up in their tissues and bloodstream, their blood pressure increases. The Cai lab hopes to provide novel insight into the development of essential hypertension.
