Iron deposits have been thought to play a role in the pathology of multiple sclerosis, although it's not known whether deposits of certain metals are a cause or consequence of disease. New imaging research is helping to answer that question.
A newly identified set of microRNAs may give scientists fresh insight into how protein levels in the brains of Alzheimer's patients are regulated.
Biomarkers are becoming increasingly useful to doctors as a tool to help diagnose patients earlier, predict the course of disease and tailor more individualized treatment regimens.
In recent years, studies have shown that the brains of patients with Alzheimer's disease have an overload of certain biological metals--such as iron, copper and zinc. Now, researchers are trying to figure out whether these metal ions actually cause neurodegeneration in Alzheimer's or are a byproduct of other pathologic processes occurring in the body.
Multiple myeloma, one of the most common types of blood cancer, has been linked to a gene that's responsible for regulating the aging process in the human body.
A research team with the UC Davis MIND Institute believes an excess of cerebrospinal fluid and enlarged brain size in infancy could be two biomarkers for autism.
U.K. researchers say they've come up with a viable bladder cancer test that detects biomarkers for the disease through urine odor.
An international team of researchers from Boston and The Netherlands see DNA fragments in the blood as potential markers of coronary art disease. Their work is published in the American Heart Association journal Arteriosclerosis, Thrombosis, and Vascular Biology.
Researchers at the University of North Carolina at Chapel Hill have found that genetically engineered mouse models are able to predict how humans will respond to different chemotherapy drug combinations used to fight breast cancer.
In what could be a significant advance toward better treatments for pancreatic cancer--a deadly type of cancer with an overall 5-year survival rate of about 6%-- scientists have developed what they say is the first-of-its-kind human-cell model of the disease.
