COLUMBUS, Ohio — New research shows that oncolytic viruses, which are engineered to destroy cancer cells, might be more effective in treating deadly brain tumors if equipped with an enzyme that helps them penetrate the tumor.
The enzyme, called …
AUGUSTA, Ga. — The inhibition or removal of an enzyme may prevent or treat ischemic retinopathy by stalling growth of unwanted vessels in the retina, Medical College of Georgia researchers say.
Ischemic retinopathy is characterized by uncont…
PHILADELPHIA – A team from the University of Pennsylvania School of Medicine and Utrecht University has deciphered a key step in an evolutionarily old branch of the immune response. This system, called complement, comprises a network of proteins…
A new study by German researchers found that a variation in the PNPLA3 (adiponutrin) gene was associated with cirrhosis of the liver and elevated transaminase (liver enzyme) levels in alcoholic Caucasians. The risk of cirrhosis in alcoholics in the …
