Taking a biopsy of a brain tumor is a complicated and invasive surgical process, but a team of researchers at Washington University in St. Louis is developing a way that allows them to detect tumor biomarkers through a simple blood test.
Studying brain scans and cerebrospinal fluid of healthy adults, scientists have shown that changes in key markers of Alzheimer’s disease during midlife may help identify those who will develop dementia years later, according to new research.
Three promising biomarkers being studied to detect Alzheimer’s disease in its early stages appear to undergo a surprising shift as patients develop symptoms of dementia, researchers led by Anne Fagan, PhD, at the School of Medicine report.
School of Medicine researchers have shown that several markers for presymptomatic Alzheimer’s disease identified in recent years are accurate predictors of Alzheimer’s years before symptoms develop. Catherine Roe, PhD, says researchers found no differences in the accuracy of the biomarkers.
On April 15, the Supreme Court will hear oral argument in Association for Molecular Pathology v. Myriad Genetics, a case that could answer the question, “Under what conditions, if any, are isolated human genes patentable?” Kevin Emerson Collins, JD, patent law expert and professor of law at Washington University in St. Louis, believes that layered uncertainties make this case an unusually difficult case in which to predict the outcome.
Scientists have assembled the most detailed chronology to date of the human brain’s long, slow slide into full-blown Alzheimer’s disease. Through an international research partnership known as the Dominantly Inherited Alzheimer’s Network (DIAN), scientists at Washington University and elsewhere evaluated pre-symptomatic markers of Alzheimer’s disease in subjects from families genetically predisposed to develop the disorder.
In the first large trial of its kind in the United States, researchers have shown that estrogen-lowering drugs can shrink tumors and reduce mastectomy rates for patients with stage 2 or 3 breast cancer.
Walking, jogging and other forms of regular aerobic exercise may actually ward off the onset of Alzheimer’s disease pathology in the brain, suggests newly published research from Washington University in St. Louis.
