Scripps Florida Scientists Awarded Grant to Develop New Diagnostics for Cancer, Rheumatoid Arritis, Colitis

Scripps Florida Scientists Awarded Grant to Develop New Diagnostics for Cancer, Rheumatoid Arthritis, Colitis JUPITER, FL, May 1, 2014 Scientists from the Florida campus of The Scripps Research Institute (TSRI) have been awarded a $2.3 million grant from the National Institute of General Medical Sciences of the National Institutes of Health to develop new technology to diagnose cancer, rheumatoid arthritis and colitis.

Paul Thompson, a TSRI associate professor, will be the primary principal investigator for the four-year study.

We've already identified a number of biomarkers for rheumatoid arthritis that we're in the process of validating, Thompson said. The platform we are developing is faster and more versatile than existing technologies.

Such biomarkers could allow for better, more individually tailored treatments because they could be used to diagnose and monitor disease progression or remission as patients experience different treatment options.

At the heart of the new study is a unique group of enzymes known as protein arginine deiminases (PAD). An increase in PAD activity has been noted in a number of conditions, such as inflammatory diseases like rheumatoid arthritis as well as cancer and Alzheimer's disease.

PADs participate in reactions in the body that form the amino acid citrulline in proteins through a process known as citrullination, a modification that can have a significant impact on the structure and function of the modified proteins. While the exact role of citrullination remains unknown, inhibition of citrullination in animal models, using a compound developed by Thompson, has been shown to alleviate the severity of rheumatoid arthritis, ulcerative colitis, atherosclerosis, lupus, nerve damage and cancer.

In addition to developing biomarkers, the scientists will use the grant to better understand this modification and whether it provides a common link among these disparate diseases.

The number of the grant is 1R01GM110394-01.

About The Scripps Research Institute

The Scripps Research Institute (TSRI) is one of the worlds largest independent, not-for-profit organizations focusing on research in the biomedical sciences. TSRI is internationally recognized for its contributions to science and health, including its role in laying the foundation for new treatments for cancer, rheumatoid arthritis, hemophilia, and other diseases. An institution that evolved from the Scripps Metabolic Clinic founded by philanthropist Ellen Browning Scripps in 1924, the institute now employs about 3,000 people on its campuses in La Jolla, CA, and Jupiter, FL, where its renowned scientists including three Nobel laureates work toward their next discoveries. The institutes graduate program, which awards PhD degrees in biology and chemistry, ranks among the top ten of its kind in the nation. For more information, see www.scripps.edu.
