Radiotherapy may improve heart function by reducing inflammatory immune cells Cardiologists and radiation oncologists at Washington University School of Medicine in St. Louis pioneered the use of radiation therapy — a strategy typically used against cancer — to treat patients with a life-threatening abnormal heart rhythm called ventricular tachycardia.

Researchers at Washington University School of Medicine in St. Louis have found an innovative way to block infection by a variety of alphaviruses, a group of mosquito-borne viruses that can cause joint and brain infections in people. The study, led by Michael S. Diamond, MD, PhD, the Herbert S. Gasser Professor of Medicine, and Daved […]

In their newly-published article in Nature Communications, a multi-center group led by Ying Maggie Chen, MD, PhD, WashU Division of Nephrology, describes previously unknown mechanisms of action of mesencephalic astrocyte-derived neurotrophic factor (MANF) and its therapeutic function, with regards to kidney disease.  MANF is a secreted endoplasmic reticulum (ER) protein that possesses cytoprotective properties.

Epigenetics of cancer critical in understanding tumor initiation, growth and spreading For decades, scientists have been sequencing the DNA of many cancer types, identifying errors in the genetic code to help understand the formation of tumors, how they grow and what leads to their spreading. But sometimes cancer is driven by subtle changes in the […]

Complete picture of genetic errors can advance precision medicine approaches to treatment A new test for two blood cancers — developed by a team at Washington University School of Medicine in St. Louis — is the first whole-genome sequencing test for cancer to be approved for reimbursement by the Centers for Medicare & Medicaid Services. […]

Understanding of molecular basis of cancer may lead to new therapies Scientists have completed a deep analysis of the proteins driving cancer across multiple tumor types, information that can’t be assessed by genome sequencing alone. Understanding how proteins operate in cancer cells raises the prospect of new therapies that block key proteins that drive cancer […]

Test results available in less than a minute Scientists at Washington University in St. Louis have developed a breath test that quickly identifies those who are infected with the virus that causes COVID-19. The device requires only one or two breaths and provides results in less than a minute.

Research collaboration details molecular knowledge, step toward personalized medicine Scientists at Washington University School of Medicine in St. Louis are among the leaders of a multi-institution research team that has built an atlas focused on the kidney’s myriad cells. The aim of the kidney tissue atlas is to further the understanding of kidney injury and disease.

Study could expand treatment options for patients with severe COVID-19 Two drugs commonly used to treat inflammatory diseases such as rheumatoid arthritis and psoriasis did not shorten recovery time for patients hospitalized with severe COVID-19 but did reduce the likelihood of death when compared with standard care alone, according to a national study led by […]

Insulin sensitivity improved twofold when exercise paired with 10% weight loss Researchers at Washington University School of Medicine in St. Louis have found that combining regular exercise with a 10% loss of body weight more than doubles sensitivity to insulin, compared with a 10% weight loss without exercise. Enhanced sensitivity to insulin has important health […]

Once a freak occurrence, fungi resistant to standard drugs now threaten millions of vulnerable Americans It took doctors a month to figure out a fungus had infected Glenda Brame’s bloodstream. The delay likely led to her death. The 56-year-old died in September, felled by a fungus that kills between 30% and 60% of people it […]

Studies in mice and in human immune cells link low prenatal vitamin D in mothers to insulin resistance in offspring Researchers at Washington University School of Medicine in St. Louis have identified a process in immune cells that links vitamin D deficiency during pregnancy to an increased risk of Type 2 diabetes in offspring. The […]

The association of donor hepatitis C virus infection with 3-year kidney transplant outcomes in the era of direct-acting antiviral medications Tarek Alhamad, MD, MS, MBA, Associate Professor of Medicine, Medical Director of Transplant Nephrology, Division of Nephrology, recently had two manuscripts published in JAMA Open and the American Journal of Transplantation regarding new findings of […]

Primary cilia are vital cell-surface sensory organelles, but their physical dimensions have eluded characterization due to difficulty in isolating and studying these enigmatic structures, especially in human tissues. In the present study, we use a multi-scale surface scanning approach to enable a 3D architectural study of human primary cilia, the first in pancreatic islets and […]

Diabetes researchers at Washington University School of Medicine in St. Louis have uncovered at least one reason insulin-secreting cells made from stem cells in the lab don’t work as well as natural cells. The discovery could help speed progress toward making insulin-secreting cells — called islet beta cells — more effective in the treatment of […]

In April, Fumihiko Urano, MD, PhD was featured in the documentary “Colorado Voices: Ellie White,” to raise awareness of the rare genetic disorder, Wolfram syndrome. The short documentary was published by Rocky Mountain PBS and tells the story of Colorado college student Ellie White, who lives with the disorder. Although the disorder is very rare […]

Researchers at Washington University School of Medicine in St. Louis have identified four important signs and symptoms that signal an elevated risk of early-onset colorectal cancer. These red flags may be key to earlier detection and diagnosis of early-onset colorectal cancer among younger adults. The number of young adults with colorectal cancer has nearly doubled […]

Hrishikesh Kulkarni MD, MSCI, from the Division of Pulmonary and Critical Care Medicine recently had two manuscripts published in Science Immunology and a Phase 3 clinical Trial on complement inhibition in COVID-19 in the Lancet Respiratory Medicine. Lung epithelial cell–derived C3 protects against pneumonia-induced lung injury The complement cascade is made up of innate immune defense proteins that protect […]

Researchers at Washington University School of Medicine in St. Louis have received a grant from the National Institutes of Health (NIH) to support training and mentorship for early-career physician-scientists. This relatively new funding opportunity — called Stimulating Access to Research During Residency (StARR) — will provide support for early-career physicians pursuing careers in cancer research.

EMMI helps assess uterine contractions to aid in preventing preterm deliveries Dr. Phillip Cuculich, Cardiovascular Division at Washington University School of Medicine in St. Louis, shared new findings that were published in Nature Communication. The group of doctors led by Dr. Yong Wang, published the “first-in-woman” study blending the disciplines of cardiac electrophysiology and obstetrics. […]
