Recognizing new aneurysm syndrome can save lives

...ndrome's responsible genes had not previously been linked to the syndrome's individual characteristics in people. The dozen or so mutations identified so far reduce the ability of the receptor to bind TGF-beta and transmit its signal, but that's only indirectly the cause of the syndrome, Dietz suggests. "W...

Pro-inflammatory enzyme linked to diabetes; Immune system's macrophages may be key to treatment

...zyme that initiates inflammation has been directly linked to insulin resistance and resulting type II diabetes by researchers at the University of California, San Diego (UCSD) School of Medicine. In addition, the team suggests that inhibition of the enzyme in the immune system's macrophages may be a new di...

Discovery promises simpler therapy for sickle cell disease

"Even so," says Dr. Yaylayan, "food companies and government agencies are keeping a close eye on the situation. It's important to know exactly what chem...

Cell research signals cancer hope

...rface of the cell known as 'Notch', which has been linked to a form of leukaemia called T-ALL. The Notch receptor, of which there are four types in humans, is unusual in that once it has picked up a signal, it splits into two and part of it actually becomes the signal on its journey to the cell nucleus. Wha...

The authors conclude that IRS-1 and IRS-2 are complementary in the regulation of overall liver metabolism but with differential effects on gluconeogenesis and lipogenesis. This study pro...

Joslin scientists show knocking out two key signals will cause diabetes
