Researchers find enzyme that triggers hardening of the arteries

An enzyme found only in the liver and intestines may play a crucial role in the development of hardening of the arteries — or atherosclerosis, a research team from Wake Forest University Baptist Medical Center and the University of California, San Francisco, report in the Proceedings of the National Academy of Sciences.

The narrowing of arteries through atherosclerosis is a major contributor to heart attacks and strokes.

The confirmation of the relationship between the enzyme, AC

Female Hormones Found To Protect Against Harmful Effects Of Fructose

Groundbreaking study in female mice links estrogen, lower blood pressure, and insulin resistance, despite a high fructose diet

Bethesda, MD – High-fructose corn syrup replaced sucrose (table sugar) as a sweetener in most grocery products some 20 years ago. Today, about nine percent of the average dietary energy intake in the U.S. comes from fructose. However, a number of nutritionists are alarmed by the amount of the public’s consumption, as previous research has demonstrated that a

Researchers achieve germline transmission of ’gene knockdown’ in mice

RNA interference (RNAi) has emerged as an extremely versatile and powerful tool in biomedical research. A new study published in the February issue of Nature Structural Biology reports the creation of transgenic mice in which inherited RNAi lowers or silences the expression of a target gene, producing a stable “gene knockdown.” This finding extends the power of RNAi to genetic studies in live animals, and has far-reaching implications for the study and treatment of many human diseases.

Ant agriculture: 50 million years of success

Fungus-growing ants practice agriculture and have been doing so for the past 50 million years according to research published in the Jan. 17 issue of Science. These ants not only grow fungus gardens underground for food but also have adapted to handling parasitic “weeds” that infect their crops.

The team of scientists who collaborated on this analysis includes Ted Schultz of the Smithsonian’s National Museum of Natural History, Bess Wong of the Smithsonian Tropical Research Institute, Came

Scripps Scientists Discover Rich Medical Drug Resource in Deep Ocean Sediments

Promising cancer-fighting candidates emerge from tropical ocean ‘mud’

Although the oceans cover 70 percent of the planet’s surface, much of their biomedical potential has gone largely unexplored. Until now.

A group of researchers at Scripps Institution of Oceanography at the University of California, San Diego, have for the first time shown that sediments in the deep ocean are a significant biomedical resource for microbes that produce antibiotic molecules.

New techniques in plant chloroplast division hold hope for agriculture

Ground-breaking research at the University of Leicester into the division of chloroplasts holds out hope of a safer way of genetically modifying crops, with implications for agriculture particularly in the developing world.

Using three plant types – Arabidopsis, tomato and rice – Dr Simon Geir Møller has been working with colleagues in the University of Leicester Department of Biology and at the Laboratory of Plant Molecular Biology at the Rockefeller University in New York to examine how ch
