Kidney-damaging protein offers clue to new treatment

CINCINNATI--Scientists led by a University of Cincinnati (UC) kidney expert have found that a naturally occurring protein that normally fights cancer cells can also cause severe kidney failure when normal blood flow is disrupted.

This finding, seen in mice in which the gene controlling the protein is actually expressed or "turned on," could provide a target for drugs that will reduce the risk of kidney damage in humans, the researchers believe.

Acute kidney failure is a life-threatening illness caused by sudden, severe loss of blood flow to the kidneys (ischemia). Despite advances in supportive care, such as dialysis, severe kidney injury is a major cause of death.

The scientists, headed by Manoocher Soleimani, MD, director of nephrology and hypertension at UC and the Cincinnati Veterans Affairs Medical Center, report their findings in the Dec. 1, 2005, issue of the Journal of Clinical Investigation.

The protein, thrombospondin (TSP-1), is known for its role in fighting cancer. It does this by killing off cancer cells and preventing the tumor from building a greater blood supply.

Although TSP-1 causes irreversible, severe kidney damage when blood flow to mouse kidneys is disrupted, the researchers say, this only occurs in animals whose TSP-1 gene is turned on.

The study showed that the protein damages kidney cells when blood flow is reduced for 30 minutes or more. When blood flow is restored to the kidneys, if TSP-1 protein is present, normal kidney function doesn't return.

"This raises the important possibility that TSP-1 may serve as a target in preventing or successfully treating acute kidney failure," said Dr. Soleimani. "Understanding the mechanisms of kidney cell injury moves us that much closer to preventing this life-altering damage from happening.

"If we can develop a drug that will inhibit or turn off the TSP-1 gene function, then severe kidney damage could be prevented--even during a 30
