Jekyll and Hyde: Cells’ executioner can also stave off death
ATLANTA — An enzyme viewed as an executioner, because it can push cells to commit suicide, may actually short circuit a second form of cell death, researchers at Emory University School of Medicine have discovered.
The finding could shift drug di…
Study links vitamin D to lung cancer survival
ANN ARBOR, Mich. — Recent research suggests vitamin D may be able to stop or prevent cancer. Now, a new study finds an enzyme that plays a role in metabolizing vitamin D can predict lung cancer survival.
The study, from researchers at the U…
1 group of enzymes could have a positive impact on health, from cholesterol to osteoporosis
Montreal, February 16, 2011 — Recent studies conducted at the Institut de recherches cliniques de Montréal (IRCM) on a group of PCSK enzymes could have a positive impact on health, from cholesterol to osteoporosis. A team led by Dr. Nabil G. Seid…
Cancer breakthrough to prevent heart failure and increase survival rates
A breakthrough by scientists at Queen’s University Belfast could help reduce heart failure in cancer patients around the world, and ultimately increase survival rates.
Scientists at Queen’s Centre for Vision and Vascular Science have discovered …
Firefly protein lights pathway to improved detection of blood clots
The enzyme that makes fireflies glow is lighting up the scientific path toward a long-sought new medical imaging agent to better monitor treatment with heparin, the blood thinner that millions of people take to prevent or treat blood clots, scientis…
Breathing easy: LSU biochemists offer first 3-D model of asthma-causing inflammation enzyme
BATON ROUGE — Inflammation is a healthy response in reaction to potentially harmful presences in the body. But when it starts in the lungs and builds up to a full-fledged asthma attack, it can be downright deadly. Chronic inflammation has been …
Sprouts? Supplements? Team them up to boost broccoli’s cancer-fighting power
URBANA — A new University of Illinois study provides convincing evidence that the way you prepare and consume your broccoli matters, and also suggests that teaming broccoli with broccoli sprouts may make the vegetable’s anti-cancer effect almost t…
Discovery could lead to new therapies for asthma, COPD
Researchers have proved that a single “master switch” enzyme, known as aldose reductase, is key in producing excess mucous that clogs the airways of people with asthma and chronic obstructive pulmonary disease (COPD). The enzyme’s action can be bloc…
2 bacterial enzymes confer resistanceto common herbicide, say MU researchers
COLUMBIA, Mo. — In an article in the Nov. 23 issue of the journal The Proceedings of the National Academy of Science, researchers with Dow AgroSciences and the University of Missouri report on two bacterial enzymes that, when transformed into corn…
Scripps Research scientists find measles’ natural nemesis
LA JOLLA, CA — January 20, 2011 — Scientists at The Scripps Research Institute have found that a known enzyme in cells protects against measles virus, likely by altering the virus’s genetic material, RNA. Cells lacking the enzyme become highly v…
Chemists document workings of key staph enzyme — and how to block it
CHAMPAIGN, Ill. — Researchers have determined the structure and mechanism of an enzyme that performs the crucial first step in the formation of cholesterol and a key virulence factor in staph bacteria.
Chemists at the University of Illino…
