Mayo Clinic finds experimental drug inhibits growth in all stages of common kidney cancer
Date:4/30/2013

JACKSONVILLE, Fla. Researchers at Mayo Clinic's campus in Florida have discovered a protein that is overly active in every human sample of kidney cancer they examined. They also found that an experimental drug designed to block the protein's activity significantly reduced tumor growth in animals when used alone. Combining it with another drug already used to treat the cancer improved the effectiveness of both.

The findings, reported in the April 30 online issue of Clinical Cancer Research, offer a much-needed potential new direction for the treatment of clear cell renal cell carcinoma, which accounts for almost 85 percent of kidney cancer cases in the United States. More than 57,000 diagnoses of kidney cancer occur yearly in the U.S. with greater than 13,000 deaths.

"There is a clear need for new therapies for this common cancer. With very few exceptions, patients inevitably become resistant to all available treatments," says the study's senior investigator, molecular biologist John Copland, Ph.D.

Their findings might be relevant to the treatment of other cancers, says Christina von Roemeling, the study's lead author. The protein they identified is produced by the stearoyl CoA desaturase 1 (SCD1) gene, which has also been found to be over active in a number of other cancers, including lung, stomach, breast, prostate, ovary and colon cancers.
