Why Every Pancreatic Cancer Patient Should Consider Genetic Testing

Genetics may play a larger role in pancreatic cancer than previously thought, an expert panel has found. It’s led to the American Society of Clinical Oncology recommending that genetic testing be offered to anyone diagnosed with pancreatic cancer. The goal: to help identify family members who might be at greater risk. “It […]

Researchers use zinc to target insulin-producing cells with regenerative drug

An insulin injection can manage diabetes symptoms, but actually curing the disease would mean healing cells in the pancreas that produce insulin, a hormone that regulates the amount of sugar in blood. One promising approach may be to stimulate the regeneration of those cells with drugs. But there’s a major […]

New method for studying ALS more effectively

The neurodegenerative disease ALS causes motor neuron death and paralysis. However, long before the cells die, they lose contact with the muscles as their axons atrophy. Researchers at Karolinska Institutet have now devised a new method that radically improves the ability to study axons and thus to better understand the […]

Elevated hormone flags liver problems in mice with methylmalonic acidemia

Researchers have discovered that a hormone, fibroblast growth factor 21 (FGF21), is extremely elevated in mice with liver disease that mimics the same condition in patients with methylmalonic acidemia (MMA), a serious genomic disorder. Based on this finding, medical teams treating patients with MMA will be able to measure FGF21 levels to […]
