Mayo Clinic to Study 10,000 Patients for Drug-Gene Safety

ROCHESTER, Minn. -- Mayo Clinic, in collaboration with Baylor College of Medicine, is planning to launch a study of 10,000 Mayo biobank members for potential risk of drug reactions or lack of drug effect based on each individual’s genome.Logotipo del Centro para Medicina Personalizada Researchers will be sequencing the DNA of the biobank members for 69 different genes that can influence how patients’ metabolize or react to different drugs. The goal is to determine which “pharmacogenomic” findings are relevant to that individual patient and to insert that information into their medical records – providing an “early warning system” to prevent adverse drug reactions or ineffective treatments.

“This is a huge step toward bringing knowledge of pharmacogenomics into patient care,” says Richard Weinshilboum, M.D., Pharmacogenomics Program Director at Mayo Clinic’s Center for Individualized Medicine and the Mary Lou and John H. Dasburg Professor of Cancer Genomics. “Most importantly, it has the potential of preventing errors and identifying the most appropriate drugs and individualized treatments for thousands of patients – thanks to research on the human genome.”

Asthma Discovery May Lead to New Therapeutic Approach

Embargoed: Do not release before 2:00 p.m. U.S. Eastern Time, April 22, 2015

Mayo Clinic researchers and collaborators have discovered a key cellular mechanism that contributes to bronchoconstriction and inflammation in asthma. Their studies may lead to a novel, effective asthma therapy for patients. The findings appear in the journal Science Translational Medicine.illustration of healthy lung and airway, airway with mucous membrane and buildup

The team of researchers from Mayo Clinic, Cardiff University in Wales, King’s College London, the University of Manchester and the Open University in the United Kingdom, as well as the University of California San Francisco, showed that elevated extracellular calcium as well as other internal chemicals released in asthma can activate a “calcium-sensing receptor” (CaSR) on airway cells. The researchers found that CaSR expression is increased in asthma, and contributes to enhanced bronchoconstriction and inflammation that is typically seen in asthma. Importantly, they found that the effects of CaSR can be reversed by CaSR antagonists, also called calcilytics.

Effective Leadership: One Remedy for Physician Burnout

Burnout is a common problem among U.S. doctors and studies suggest it adversely impacts quality of care and patient satisfaction. Many factors impact how physicians perceive their career. A new study suggests there’s an interesting correlation between physician burnout and the effectiveness of their supervisors. That’s what researchers found at Mayo Clinic when they undertook a large internal study on the satisfaction of physicians and the leadership qualities of their supervisors. The findings appear today in the journal Mayo Clinic Proceedings.

 “We found that at the work-group level, 11 percent of the variation in burnout and 50 percent of the variation in satisfaction among physicians was attributable to the leadership behaviors of their supervisor,” says Tait Shanafelt, M.D., Mayo researcher and first author of the study. “The behaviors of physician supervisors have a direct impact on the personal well-being of the physicians they lead.”

Journalists: Sound bites with Dr. Shanafelt are available in the downloads.

New treatments for cancer and heart disease dominate the 2015 research awards recently announced by the Minnesota Partnership for Biotechnology and Medical Genomics. The state-supported funding was distributed among six research teams, based on competitive applications. Each team represents researchers from Mayo Clinic and the University of Minnesota. A seventh grant was also awarded to help support commercialization of a research finding previously funded by the Partnership.University of Minnesota Research Partnership Logo

“These are seed grants, aimed at providing innovative researchers the means to get a scientific project off the ground and on the way toward a possible new treatment,” says Eric Wieben, Ph.D., of Mayo Clinic, program co-director for the Minnesota Partnership.

“I’m pleased that we are entering our second decade of scientific progress with so many strong projects that could potentially change how medicine is practiced,” says Tucker LeBien, Ph.D., of the University of Minnesota, program co-director.

The seven grants totaled just under $5.5 million.

Mayo Clinic Center for Tuberculosis Launches New TB Journal

The Mayo Clinic Center for Tuberculosis,  a regional training and consultation center at Mayo Clinic's campus in Rochester, Minn, is today launching a new medical journal, the Journal of Clinical Tuberculosis and Other Mycobacterial Diseases. The online journal is published by Elsevier.cover of Clinical Tuberculosis magazine

“We believe that the Journal of Clinical Tuberculosis and Other Mycobacterial Diseases fills an unmet need by providing a platform for the dissemination of the results of clinically relevant research,” say the editors in their inaugural editorial for the publication. They also cite the continue spread of tuberculosis as a global health problem, making it the second greatest cause of death from infectious diseases after HIV.

“We are very excited that we are launching this journal on World TB Day and hope that it will effectively advance new knowledge that will ultimately help end this terrible disease,” says Editor-in-Chief Zelalem Temesgen, M.D [Za-La-Lum Tah-mezg-in]. Two other Mayo Clinic physician-researchers, Stacey Rizza, M.D. and John Wilson, M.D., will serve as associate editors. All three are members of the Division of Infectious Diseases at Mayo Clinic and members of the tuberculosis center. An editorial board composed of leading experts in the field from around the globe has already been established to help advance the journal's mission.

Mayo Clinic and Collaborators Find New Class of Drugs that Reduces Aging in Mice

A new class of drugs identified and validated by Mayo Clinic researchers along with collaborators at Scripps Research Institute and others, clearly reduces health problems in mice by limiting the effect of senescent cells — cells that contribute to frailty and diseases associated with age. The researchers say this is a first step toward developing similar treatments for aging patients. Their findings appear today in the journal Aging Cell.

 “If translatable to humans — which makes sense as we were using human cells in many of the tests – this type of therapy could keep the effects of aging at bay and significantly extend the healthspan of patients,” says James Kirkland, M.D., Ph.D., head of the Mayo Clinic Kogod Center on Aging and senior author of the study.two senior citizens, elderly couple walking down a road or path

 The drugs — called senolytics — selectively kill senescent cells without harming nearby cells and tissue, to reduce heart and vascular problems, muscle weakness, osteoporosis, and neurological problems. Senescent cells are cells that appear with aging and at sites of many age-related diseases. They produce factors that can damage the cells and tissues around them and at a distance, amplifying their effects. In many examples, the drugs caused significant and visible reduction of multiple conditions after just one dose – and remained therapeutic for up to seven months. The researchers say that this long lasting effect is consistent with a change in cellular or tissue composition.
