Autism linked with disorganized structure of brain's white matter

It's still unclear what's different in the brains of people with autism spectrum disorders (ASDs), but evidence from genetic and cell studies points to abnormalities in how brain cells (neurons) connect to each other. A study at Children's Hospital Boston now provides visual evidence associating autism with a disorganized structure of brain connections, as well as defects in myelin -- the fatty, insulating coating that helps nerve fibers conduct signals and that makes up the brain's white matter.

Growth hormone PDGF-BB and blood protein EPO implicated in development of cancer

Researchers at the Swedish medical university Karolinska Institutet have demonstrated that a growth hormone, PDGF-BB, and the blood protein EPO are involved in the development of cancer tumours and that they combine to help the tumours proliferate in the body.

Plasma can inactivate and prevent replication of adenoviruses

Life-threatening viruses such as HIV, SARS, hepatitis and influenza, could soon be combatted in an unusual manner as researchers have demonstrated the effectiveness of plasma for inactivating and preventing the replication of adenoviruses.

Low vitamin D levels associated with higher degrees of insulin resistance

A recent study of obese and non-obese children found that low vitamin D levels are significantly more prevalent in obese children and are associated with risk factors for type 2 diabetes. This study was accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).

Study reveals how wide brain networks are activated during music listening

Finnish researchers have developed a groundbreaking new method that allows to study how the brain processes different aspects of music, such as rhythm, tonality and timbre (sound color) in a realistic listening situation.

P-Rex1 gene plays a key role in the spread of malignant melanoma

SCIENTISTS in Glasgow have made an important discovery in the fight against malignant melanoma, the most dangerous form of skin cancer.

Study shows new biochemical disturbances in the brains of children with ADHD

A new study at örebro University in Sweden shows that children with ADHD have nearly 50 percent less of a protein that is important for attention and learning. The finding may mean that there are other biochemical disturbances in the brains of individuals with ADHD than was previously believed.

Scientists discover new candidate gene for Dravet syndrome

Dravet syndrome is a severe genetic epilepsy that appears early in life. About 75 percent of cases can be attributed to mutations in the SCN1A gene encoding the sodium channel NaV1.1. The remaining patients with this syndrome are without a definitive molecular genetic diagnosis. Research presented today at the American Epilepsy Society's 65th Annual Meeting has found a non-SCN1A candidate gene and suggests that Dravet syndrome may be caused by any one of a number of yet unidentified genes.

CPEB4 protein plays a crucial role in cancer progression

A study by researchers Ra-l M-ndez, ICREA Research Professor at the Institute for Research in Biomedicine (IRB Barcelona) and Pilar Navarro at the IMIM (Institut de Recerca Hospital del Mar, Barcelona) describes a new reprogramming mechanism for the expression of genes responsible for turning a healthy cell into a tumor cell.

Cancer cells can 'bag up and bin' a toxic protein to cheat death

Cancer Research UK scientists have discovered that cancer cells can 'bag up and bin' a toxic protein to cheat death - revealing a new Achilles heel in cancer cells that could be targeted for treatment, reveals research in Nature Cell Biology today.

Researchers identify ADHD gene variants involved in glutamate signaling

Pediatric researchers analyzing genetic influences in attention-deficit/hyperactivity disorder (ADHD) have found alterations in specific genes involved in important brain signaling pathways. The study raises the possibility that drugs acting on those pathways might offer a new treatment option for patients with ADHD who have those gene variants—potentially, half a million U.S. children.

Hypothalamus may be involved in generating laughter

Anecdotal evidence suggests that the hypothalamus, a structure lying deep within the brain may be involved in generating laughter. Gelastic epilepsy, a rare condition characterized by laughing seizures, is commonly the result of a congenital brain lesion within the hypothalamus.

Researchers uncover binding pocket of 'functional significance' in Ras oncoprotein

A drug discovery team at Genentech, Inc., has uncovered a chink in the molecular armor of Ras, the most commonly occurring oncogene, which is a gene that when mutated has the potential of causing cancer in humans.
