5-LO enzyme plays important role in the survival of leukaemic AML stem cells

Despite improved therapy, only one out of every two adult patients survive acute myeloid leukaemia (AML). The mean survival time for this disease, which predominantly occurs in the elderly, is less than a year for patients over 65 years. It is assumed that leukaemic stem cells, which cannot be completely eliminated during treatment, are the origin of relapse.

Researchers at NIH-FEI Living Lab for Structural Biology achieve breakthrough biological results

FEI is pleased to announce that researchers at the NIH-FEI Living Lab for Structural Biology have achieved breakthrough biological results, using FEI’s Titan Krios™ transmission electron microscope (TEM), to elucidate the structural mechanism by which glutamate receptors participate in the transmission of signals between neurons in the brain. Their work is described in Nature, “Structural Mechanism of Glutamate Receptor Activation and Desensitization,” by Meyerson, et al., (DOI: 10.1038/nature13603), http://www.nature.com/nature/journal/vaop/ncurrent/full/nature13603.html .

Epigenetic control of serotonin transporter predicts human brain function

The tiny addition of a chemical mark atop a gene that is well known for its involvement in clinical depression and posttraumatic stress disorder can affect the way a person's brain responds to threats, according to a new study by Duke University researchers.

Findings shed light on why PPARγ activators have side effect of promoting weight gain

The brain plays a central role in regulating appetite and whole-body metabolism. A protein known as PPARγ is important in the brain's control of food intake and body weight, but the identity of the neurons regulating this process has been unclear.

Study shows that mice can identify specific odors amid complex olfactory environments

For many animals, making sense of the clutter of sensory stimuli is often a matter or literal life or death. Exactly how animals separate objects of interest, such as food sources or the scent of predators, from background information, however, remains largely unknown.
