Mice provide insight into genetics of autism spectrum disorders

The CHD8 gene is associated with some cases of human autism. A new study shows that mice with mutated CHD8 show defects in brain development and behavioral changes, and may give insight into genetic causes of autism spectrum disorders.

Human enzyme can reduce neurotoxic amyloids in a mouse model of dementia

A naturally occurring human enzyme -called cyclophilin 40 or CyP40- can unravel protein aggregates that contribute to both Alzheimer’s disease and Parkinson’s disease, according to a study. The finding may point toward a new therapeutic strategy for these diseases.

Brains evolved to need exercise

Mounting scientific evidence shows that exercise is good not only for our bodies, but for our brains. Yet, exactly why physical activity benefits the brain is not well understood. Researchers suggest that the link between exercise and the brain is a product of our evolutionary history and our past as hunter-gatherers.

Computer model simulates sense of touch from the entire hand

Neuroscientists have developed a computer model that can simulate the response of nerves in the hand to any pattern of touch stimulation on the skin. The tool reconstructs the response of more than 12,500 nerve fibers with millisecond precision, taking into account the mechanics of the skin as it presses up against and moves across objects.

Glycans as biomarkers for cancer?

Glycosylated proteins are often overexpressed in tumor cells and thus could serve as tumor markers, especially those with the interesting molecule sialic acid as their sugar moiety. Scientists now report on a bioorthogonal labeling test for sialylated glycoproteins based on a glycoproteomics approach. This assay not only assesses the level of sialylated glycans in the tumor cell membranes, but also identifies up- or downregulated proteins directly in the prostate cancer tissue.
