Researchers have uncovered a number of compounds – including caffeine – that boost production of the enzyme NMNAT2, which may protect against dementia.

Enzymatic activity essential for vision may provide target for drug transport

Researchers at Case Western Reserve University School of Medicine have uncovered the mechanism that enables the enzyme Lecithin: retinol acyltransferase (LRAT) to store vitamin A-a process that is…

New Link Identified Between High-Fat ‘Western’ Diet And Atherosclerosis

Columbia University Medical Center (CUMC) researchers have found that a diet high in saturated fat raises levels of endothelial lipase (EL), an enzyme associated with the development of atherosclerosis, and, conversely, that a diet high in omega-3 polyunsaturated fat lowers levels of this enzyme…

Spicing Up Broccoli Boosts Its Cancer-Fighting Power

Teaming fresh broccoli with a spicy food that contains the enzyme myrosinase significantly enhances each food’s individual cancer-fighting power and ensures that absorption takes place in the upper part of the digestive system where you’ll get the maximum health benefit, suggests a new University of Illinois study…

Study Links Vitamin D To Lung Cancer Survival

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 University of Michigan Comprehensive Cancer Center, suggests that this enzyme stops the anti-cancer effects of vitamin D…
