How do a couple of universally expressed proteins in stem cells and developing embryos influence an individual cell’s ultimate fate — whether it ultimately becomes, for example, a retinal cell, a heart muscle cell, or a stomach lining cell? That’s the question that Rajesh C. Rao, M.D., and his colleagues at […]

THERE’S NO SHORTAGE of ways to kill a cancer cell. Cut it out, poison it, blast it with radiation, shower it with killer immune cells—they all get the job done. But there is a shortage of good ways to kill cancer cells. One that knocks out all the bad cells in one swipe, […]

Lab-grown brain organoids developed from a patient’s own glioblastoma, the most aggressive and common form of brain cancer, may hold the answers on how to best treat it. A new study in Cell from researchers at Penn Medicine showed how glioblastoma organoids could serve as effective models to rapidly test personalized treatment […]

Bone loss that can lead to osteoporosis and fractures is a major problem for cancer patients who receive chemotherapy and radiation. Since the hormone estrogen plays an important role in maintaining bone health, bone loss is especially pronounced among postmenopausal women with breast cancer who are treated using therapies aimed […]

For the first time, researchers at Michigan Medicine have demonstrated that a cellular process is known to be involved in cancer and other diseases also play an important role in the growth of at least one type of normal mammalian cell. Macropinocytosis is an ancient process by which cells take […]

A multidisciplinary Michigan Medicine team is shedding new light on the role of regulatory T cells in pancreatic cancer — and, in mouse models, have uncovered a new potential target to improve immunotherapy approaches to the deadly disease. Regulatory T cells are a subpopulation of immune cells that help keep […]

DNA testing has become one of the most valuable tools that humans can rely on to discover possible traits and limitations. Simply put, DNA is the code in our cells, the most complex and richest piece of information we have about our existence. Genetic testing helped us identify changes in […]

Cancer patients may one day be able to get their entire course of radiation therapy in less than a second rather than coming in for treatment over the course of several weeks, and researchers in the Abramson Cancer Center of the University of Pennsylvania have taken the first steps toward making […]

During the years 1976 through 1980, 15% of U.S. adults were obese. Today, about 40% of adults are obese. Another 33% are overweight. Coinciding with this increase in weight are ever-rising rates of heart disease, diabetes, cancer and health complications caused by obesity, such as hypertension. Even Alzheimer’s disease may […]

Could bile acids—the fat-dissolving juices churned out by the liver and gallbladder—also play a role in immunity and inflammation? The answer appears to be yes, according to two separate Harvard Medical School studies published in Nature. The findings of the two studies, both conducted in mice, show that bile acids promote […]

Discussions about sexual health can be awkward, but for Daniela Wittmann, Ph.D., MSW, they go with the territory. As a social certified sex therapist, she sees patients with sexual health issues at the Michigan Medicine Center for Sexual Health and in the Department of Urology. She also discusses these types of issues with Parkinson’s disease patients during […]

Acute myeloid leukaemia is the most common type of leukaemia in adults. It is characterized by the pathological expansion of immature cells (myeloblasts) that invade the bone marrow and expand into the blood, affecting the production of the rest of the healthy cells. Although patients usually respond well to chemotherapy-based […]

You want your children to be successful. You want them to be smart and get good grades in school. But did you know that a big portion of academic success can actually be predicted at birth? Scientists from the University of York found that genetic factors are unbelievably important in […]

Heart disease remains the largest killer in Australia and around the world. A new study has shown that a protein therapy– recombinant human platelet-derived growth factor-AB (rhPDGF-AB) – could improve outcomes following heart attack. After a heart attack, scar tissue forms and this negatively affects heart function. Now, researchers from […]

Scientists have discovered that people who regularly sleep for more than 11 hours or less than 4 hours are 2-3 times more likely to have the incurable disease, pulmonary fibrosis, compared to those that sleep for 7 hours in a day. They attribute this association to the body clock. The […]

Brain imaging of pathological tau-protein “tangles” reliably predict the location of future brain atrophy in Alzheimer’s patients a year or more in advance, according to a new study by scientists at the UC San Francisco Memory and Aging Center. In contrast, the location of amyloid “plaques,” which have been the […]

A new study led by researchers at King’s College London has found that adolescents with particular patterns of brain development report an increased frequency in drunkenness.
