Scientists directly link lipid metabolism and cancer-associated cachexia

Scientists from Graz, Austria, have now directly linked lipid metabolism and cancer-associated cachexia. Science reports via its online channel Science Express that mice deficient in the lipid degrading enzyme Adipose Triglyceride Lipase (ATGL) are fully protected against cancer-associated cachexia.

First genome-wide mapping of DNA modification in embryonic stem cells

Stem cell researchers at UCLA have generated the first genome-wide mapping of a DNA modification called 5-hydroxymethylcytosine (5hmC) in embryonic stem cells, and discovered that it is predominantly found in genes that are turned on, or active.

UK regulators approve Europe's first clinical trial of plant-derived antibody for HIV

UK regulators have approved Europe's first clinical trial of a monoclonal antibody produced from genetically modified plants. This landmark decision sets the stage for the testing, in humans, of an anti-HIV product made from genetically modified tobacco plants. It will open the door for trials of additional plant-derived medicines treating a range of diseases.

Microglia prune connections between neurons

Gardeners know that some trees require regular pruning: some of their branches have to be cut so that others can grow stronger. The same is true of the developing brain: cells called microglia prune the connections between neurons, shaping how the brain is wired, scientists at the European Molecular Biology Laboratory (EMBL) in Monterotondo, Italy, discovered.

Scientists find distinct links between smoking during pregnancy and long-term harm for the child

Scientists now understand more about why being exposed to nicotine while you were a fetus will increase your risk of developing cardiovascular disease as an adult. "We have found distinct links between cigarette smoking or even using nicotine patches or gum and the long-term harm for the child," says Dr. DaLiao Xiao, a scientist who works at the Loma Linda University School of Medicine in California.
