Mount Sinai researchers identify promising new drug target for kidney disease

12.03.2012
Researchers from Mount Sinai School of Medicine have identified a regulator protein that plays a crucial role in kidney fibrosis, a condition that leads to kidney failure. Finding this regulator provides a new therapeutic target for the millions of Americans affected by kidney failure. The research is published in the March 11 issue of Nature Medicine.

Led by John Cijiang He, MD, PhD, Professor of Nephrology and Pharmacology and Systems Therapeutics; and Avi Ma'ayan, PhD, Assistant Professor of Pharmacology and Systems Therapeutics at Mount Sinai School of Medicine, the research team studied three mouse models of kidney fibrosis: one group of mice contained HIV viral proteins incorporated into their genome; the second group was injected with a high dose of folic acid; in the third mouse model, kidney filtration was blocked in one kidney. All of these factors cause kidney fibrosis.

The researchers gathered the genetic material of the mice and compared it to the genetic material of mice that did not have kidney fibrosis. Using a new computational systems biology algorithm and software called Expression2Kinases—developed by the Ma'ayan Laboratory at Mount Sinai—the results from these experiments were analyzed. They found that HIPK2, a protein kinase, or regulator, was highly active in the mice with kidney fibrosis. HIPK2 regulates the way certain genes are expressed and when HIPK2 is highly active this leads to kidney fibrosis. Drs. He and Ma'ayan also found that when they eliminated HIPK2, fibrosis was less prominent and the condition of the mice significantly improved.

"Our findings have important implications for people with kidney diseases, patients I treat every day," said Dr. He. "Protein kinases like HIPK2 are highly effective therapeutic targets. We look forward to exploring this further."

Incorporating a systems approach allowed the Mount Sinai team to identify a target that is a regulatory protein modified during chronic disease. The high activity of HIPK2 in kidney fibrosis was not identifiable by standard methods that examine gene expression changes alone, but by modeling a network of proteins using computational systems biology, the research team was able to home in on the regulator protein, HIPK2. Now, Mount Sinai scientists can work to develop a drug intervention that inhibits the activity of HIPK2.

"This study is an important example of the translational research we are doing at Mount Sinai," said Dr. Ma'ayan. "Using algorithms and software developed here, we worked with Dr. He, who is a kidney disease physician and scientist, to better understand what causes kidney fibrosis, and we are now one step closer to finding a therapeutic solution to a complex disease that affects millions of Americans."

Funding for this study was provided by the National Institute of Diabetes and Digestive and Kidney Diseases, a division of the National Institutes of Health in Bethesda, Md.

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
