Collaboration in Collaborative Life Sciences Building yields hypertension breakthrough

David Ellison, M.D., professor of medicine at Oregon Health & Science University and staff physician at the Portland VA Medical Center, leads a group that has been studying causes of human hypertension. In a paper published September 24th in the Journal of Clinical Investigation, “Hyperkalemic hypertension-associated cullin 3 promotes WNK signaling by degrading KLHL3”, the group identified a novel and unexpected mechanism for this hypertensive disease.  This research was done in collaboration with groups in … Read More

OHSU startup Orexigen earns FDA approval

The office of Technology Transfer and Business Development is happy to announce that a drug from  Orexigen Therapeutics Inc., called Contrave, has been approved by the FDA. This drug helps with weight management, along with a reduced-calorie diet and increased physical activity, in adults with an initial body mass index of 30 kg/m2 or greater (obese), or 27 kg/m2 or greater (overweight) who also have at least one weight-related comorbid condition. Contrave has two components: … Read More

TTBD Inventor Spotlight: Michael P. Hutchens, M.D., M.A.

The office of Technology Transfer & Business Development would like to highlight a particularly innovative or note worthy OHSU inventor and invention at the university. This quarter, our office would like to congratulate Michael P. Hutchens, M.D., M.A., for his work on the “Disinfection device for medical access sites” and the “Anesthetic vapor delivery device” that he has created and submitted to our office. Dr. Michael Hutchens is an assistant professor in the Department of … Read More

Method pioneered by OHSU researcher could become gold standard for creating embryonic stem cells

Stem cell therapies hold great promise for replacing cells that have been damaged by injury or illness. Researchers at Oregon Health and Science University recently compared two methods to create human pluripotent stem cells—those which can be transformed into any other cell type in the body—and have found a clear winner. Somatic cell nuclear transfer (SCNT) appears to be more accurate at reprogramming human skin cells to become embryonic stem cells and produces fewer epigenetic … Read More

Cardiovascular researcher wins prestigious young investigator’s award

Chi Young Shim, M.D., Ph.D., a postdoctoral researcher at the Knight Cardiovascular Institute, was awarded the prestigious 2014 Arthur E. Weyman Young Investigator’s Award at last week’s American Society of Echocardiography 25th Annual Scientific Sessions. Dr. Shim presented the results of a study which used molecular imaging with “smart” targeted microbubbles to detect the sticking of platelets to the vessel wall at various stages of atherosclerosis. Atherosclerosis, or hardening of the arteries due to plaque build-up, can … Read More

Researchers create 3-D model of elusive brain receptor

Exciting news from the Gouaux Lab this week: researchers have discovered new information about the structure of an important brain receptor that is crucial for learning and memory. Malfunction of the receptor, N-methyl-D-asparate (NMDA), is known to cause a variety of neurological disorders and diseases, but until now, researchers had limited information about how its subunits operate in the brain. Using X-ray crystallography, Dr. Gouaux and his team at the OHSU Vollum Institute created a … Read More

OHSU study finds that POLST forms honor patients’ wishes

A new study published by researchers at Oregon Health & Science University shows that the Physician Orders for Life-Sustaining Treatment program–commonly known as POLST–is effective in honoring end-of-life wishes for frail or seriously ill patients. By reviewing death records from 58,000 Oregonians, the researchers found that only 6.4% of patients who asked for comfort measures only on their POLST form died in a hospital, whereas 44.2% of patients who asked for full medical treatment died in … Read More

Study: compound found in broccoli and cauliflower lowers blood pressure

Hypertension, or high blood pressure, affects about one in three adults in the U.S. Researchers in the lab of Agnieszka Balkowiec, M.D., Ph.D., associate professor of integrative biosciences in the OHSU School of Dentistry, have contributed their expertise to a project led by Fawzy Elbarbry, Ph.D., associate professor of pharmacy at Pacific University, resulting in an important new discovery that has implications for prevention and treatment of hypertension. The study, “Modulation of Arachidonic Acid Metabolism in … Read More

OHSU researchers develop safer vector for lentivirus gene therapy

Gene therapy, a promising clinical approach to treat patients with a range of inherited diseases, often uses vectors derived from lentiviruses to insert a correcting genetic sequence into the patient’s stem cell chromosomes. While this type of treatment can provide long-term cures for inherited diseases, vectors from these viruses can also inadvertently activate cancer-causing genes because of the way they stitch or “integrate” the therapeutic DNA with human DNA. Avoiding these unwanted integrations while retaining the correcting gene has … Read More

Researchers find gene mutation that may make heart cell regeneration possible

In a paper published March 4 in Nature Communications, coauthored by Lincoln Shenje, M.D., Ph.D, assistant professor at the OHSU Knight Cardiovascular Institute, researchers describe the first found gene mutation in humans that causes heart muscle cells to proliferate beyond birth. This mutation was discovered in a rare syndrome called ALMS1 that has been reported in less than 70 people in the past 50 years worldwide. According to Dr. Shenje and colleagues, this discovery goes … Read More
