Researchers identify mechanism that leads to diabetes, blindness

The rare disorder Wolfram syndrome is caused by mutations in a single gene, but its effects on the body are far reaching. Now, researchers report that they have identified a mechanism that affects both insulin-secreting cells and neurons. The finding will aid in the understanding of Wolfram syndrome and also may be important in the treatment of milder forms of diabetes and other disorders.

Treatment target for diabetes, Wolfram syndrome

Inflammation and cell stress are major factors in diabetes. Cell stress also plays a role in Wolfram syndrome, a rare, genetic disorder that afflicts children with many symptoms, including juvenile-onset diabetes. Now scientists at Washington University School of Medicine in St. Louis and elsewhere have identified a molecule that’s key to the cell stress-modulated inflammation that causes insulin-secreting cells to die.

New target for treating diabetes and obesity

Researchers at Washington University School of Medicine in St. Louis have identified a potential target for treating diabetes and obesity. Studying mice, they found that when the target protein was disabled, the animals became more sensitive to insulin and were less likely to get fat.

The Juvenile Diabetes Research Foundation has created the Alan Permutt Career Development Award in honor of the late M. Alan Permutt, MD, who died June 10, 2012.

Brain abnormalities seen in children with severe form of diabetes

Children with a rare syndrome that includes a form of insulin-dependent diabetes have brain abnormalities that appear to set the stage for cognitive problems later in life, according to new research at Washington University School of Medicine in St. Louis. Scientists, including Tamara Hershey, PhD, had assumed those brain changes occurred late in the disease process, but the new findings suggest that some changes occur early in childhood.

Investigational diabetes drug may have fewer side effects

Drugs for type 2 diabetes can contribute to unwanted side effects, but Washington University researchers have found that in mice, an investigational drug appears to improve insulin sensitivity without side effects. The medicine works through a different pathway, which could provide additional targets for treating insulin resistance and diabetes.

Diabetes may start in the intestines, research suggests

Scientists at Washington University School of Medicine in St. Louis have made a surprising discovery about the origin of diabetes. Their research suggests that problems controlling blood sugar — the hallmark of diabetes — may begin in the intestines. The new study, in mice, may upend long-held theories about the causes of the disease.

Protein may play role in obesity, diabetes, aging

Researchers at Washington University School of Medicine in St. Louis, led by Philip Stahl, PhD, professor of cell biology and physiology have identified a potent regulator of sensitivity to insulin, the hormone that controls blood sugar levels. The new findings may help scientists find better treatments for type 2 diabetes, obesity and other health problems caused by the body’s inability to properly regulate blood sugar.
