Gene family linked to brain evolution implicated in severity of autism symptoms

Gene family linked to brain evolution implicated in severity of autism symptoms

The same gene family that may have helped the human brain become larger and more complex than in any other animal also is linked to the severity of autism, according to new research from the University of Colorado Anschutz Medical Campus. The gene family is made up of over 270 copies of a segment of DNA called DUF1220. DUF1220 codes for a protein domain — a specific functionally important segment within a protein Continue reading

Proteins that control energy use necessary to form stem cells

Proteins that control energy use necessary to form stem cells

Two proteins that control how cells break down glucose play a key role in forming human stem cells, University of Washington researchers have found. The finding has implications for future work in both regenerative medicine and cancer therapy Continue reading

New approach makes cancer cells explode

New approach makes cancer cells explode

Researchers at Karolinska Institutet in Sweden have discovered that a substance called Vacquinol-1 makes cells from glioblastoma, the most aggressive type of brain tumour, literally explode. When mice were given the substance, which can be given in tablet form, tumour growth was reversed and survival was prolonged. The findings are published in the journal Cell. Continue reading

Tequila plant possible sweetener for diabetics, helps reduce blood sugar, weight

Tequila plant possible sweetener for diabetics, helps reduce blood sugar, weight

A sweetener created from the plant used to make tequila could lower blood glucose levels for the 26 million Americans and others worldwide who have type 2 diabetes and help them and the obese lose weight, researchers have reported. The main reason it could be valuable, they explained, is that agavins, a natural form of sugar found in the agave plant, are non-digestible and can act as a dietary fiber, so they would not raise blood glucose. Their report was part of the 247th National Meeting of the American Chemical Society (ACS), the world’s largest scientific society. Continue reading

Tension triggers muscle building

Tension triggers muscle building

Skeletal muscles are built from small contractile units, the sarcomeres. Many of these sarcomeres are connected in a well-ordered series to form myofibrils that span from one muscle end to the other. Continue reading

New insights into conquering influenza

New insights into conquering influenza

Jan. 29, 2013 — Researchers from the University of Melbourne and The Walter and Eliza Hall Institute (WEHI) have discovered a new protein that protects against viral infections such as influenza. As influenza spreads through the northern hemisphere winter, Dr Linda Wakim and her colleagues in the Laboratory of Professor Jose Villadangos from the Department of Biochemistry and Molecular Biology, and the Department of Microbiology and Immunology, believe they have a new clue to why some people fight infections better than others Continue reading

Research may lead to new strategies against sepsis

Jan. 25, 2013 — Scientists at the Center for Translational Medicine at the Temple University School of Medicine are inching closer to solving a long-standing mystery in sepsis, a complex and often life-threatening condition that affects more than 400,000 people in the U.S. every year.
