Research team led by Cedars-Sinai identifies genes linked to ulcerative colitis

17.03.2010
Greater understanding of genetics of ulcerative colitis key to developing new treatments, researchers say

A study of the human genome led by Cedars-Sinai researchers has now identified genes linked to ulcerative colitis, offering clues as to what causes the condition and potential avenues for new therapies to treat the disease.

The study, published in Nature Genetics, examined genes of nearly 13,000 patients to determine which parts of the genome are linked to ulcerative colitis. The study demonstrated more than 30 regions of the genome are connected to the risk of developing ulcerative colitis.

“This gives us a number of insights into the disease,” said Dermot P.B. McGovern, M.D., Ph.D., director of Translational Medicine for the Inflammatory Bowel and Immunobiology Research Institute at Cedars-Sinai Medical Center and primary author of the paper. “An increased understanding of the genetics gives us some insight into what causes ulcerative colitis and will potentially help us indentify new therapies for ulcerative colitis.”

Understanding the genetics of the disease may also explain why the condition varies so much from patient to patient in severity, symptoms and response to therapies. In turn, said McGovern, this can lead to a more personalized approach to treating ulcerative colitis patients. For example, in addition to more effectively matching currently available medications to patients, the study may help identify entirely new avenues for research, enabling doctors to develop new treatments for ulcerative colitis.

Ulcerative colitis, one of the most common types of Inflammatory Bowel Disease or IBD, is a chronic digestive disorder. An estimated 1.4 million Americans have IBD, and about 30,000 new cases are diagnosed each year. Ulcerative colitis causes inflammation and ulcers in the top layers of the lining of the large intestine. The most common symptoms include abdominal pain, bloody diarrhea and bleeding from the rectum. Patients may also experience fatigue, weight loss and loss of appetite. Ulcerative colitis is a chronic relapsing condition with periods of remission interspersed with flares of disease, although about 10 percent of ulcerative colitis patients have symptoms chronically. Patients with ulcerative colitis can be at increased risk of developing colorectal cancer.

The study was a collaborative effort between the Inflammatory Bowel and Immunobiology Research Institute and The Medical Genetics Institute at Cedars-Sinai Medical Center, the National Institute of Diabetes and Digestive and Kidney Diseases IBD Genetics Consortium, the Genome Institute of Singapore, the Karolinksak Institutet in Sweden, the Swedish National Program for IBD genetics, The Swedish Organisation for Study of Inflammatory Bowel Diseases, and Harvard Medical School.

The Inflammatory Bowel Disease Center at Cedars-Sinai is a highly specialized patient care and research facility, dedicated to providing comprehensive diagnostic and treatment services to adults and children with IBD. In 2009, Cedars-Sinai was once again ranked among America’s best in Gastrointestinal Disorders by U.S. News and World Report.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
