Olig1 and Olig2 genes are associated with Down syndrome, scientists identify

Down syndrome is a well known cause of mental retardation and other medical problems, including early onset of Alzheimer disease. It has long been known that Down syndrome is associated with an individual having an additional copy of chromosome 21. Research findings reported in the July 18 advanced online publication of Nature Neuroscience have narrowed down the critical genetic elements responsible for some aspects of Down syndrome.

New mechanism that drives development of B-lymphocytes in bone marrow discovered

Scientists from the Department of Molecular Immunology, Institute of Biology III, Faculty of Biology and the Centre for Biological Signalling Studies, BIOSS have discovered a new mechanism that drives the development of B-lymphocytes in our bone marrow. B-lymphocytes are an important part of our immune system. Upon their activation they produce the antibodies protecting us from infections.

Species with larger brains live longer

"In the past, it was thought that one of the selective advantages of having a large brain is that it facilitates the development of new behaviour to respond to the ecological challenges that the individual has not experienced before, such as a sudden reduction in food or the appearance of a new predator ", C-sar Gonz-lez-Lagos, main author of the study and researcher at the Centre of Ecological Research and Forestry Applications (CREAF) associated with the Autonomous University of Barcelona, highlights to SINC.

New tactics for repelling, controlling disease-carrying insects

In the battle between insect predators and their prey, chemical signals called kairomones serve as an early-warning system. Pervasively emitted by the predators, the compounds are detected by their prey, and can even trigger adaptations, such a change in body size or armor, that help protect the prey. But as widespread as kairomones are in the insect world, their chemical identity has remained largely unknown. New research by Rockefeller University's Joel E. Cohen and colleagues at the University of Haifa in Israel has identified two compounds emitted by mosquito predators that make the mosquitoes less inclined to lay eggs in pools of water.

GABA disrupts working memory in neurofibromatosis type 1 patients

Imagine if your brain lost its working memory - the ability to hold and manipulate information in your mind's eye. That's the plight faced by millions of people with neurofibromatosis type 1, or NF1. The genetic condition affects one in 3,500 people and is the most common cause of learning disabilities.Now a UCLA research team has uncovered new clues about how NF1 disrupts working memory. Published in the July 12 online edition of Proceedings of the National Academy of Sciences, the findings suggest a potential drug target for correcting NF1-related learning disabilities.

Cetuximab recommended for colorectal cancer tumors without mutation in KRAS gene

In a report published in the July 2010 issue of the American Society for Clinical Oncology Post, new recommendations on the use of the drug cetuximab have been issued after officials halted enrollment in a phase III clinical trial in patients with spread of colon cancer into regional lymph nodes whose tumors had been surgically removed.

CCTP focuses on identifying, testing drugs for cancer stem cell treatment

Cancer and stem cell biology researchers at the University of Colorado are launching the nation's first program focused on identifying and testing drugs that target and destroy cells thought to be at the root of cancer-cancer stem cells (CSCs).The Cancer Stem Cell-Directed Clinical Trials Program (CCTP) is a collaboration between the University of Colorado Cancer Center and the Charles C. Gates Center for Regenerative Medicine and Stem Cell Biology, both located at the University of Colorado School of Medicine.

AMPK may regulate epigenetic mechanism: Research

AMP-activated protein kinase, or AMPK, is a master regulator protein of metabolism that is conserved from yeast to humans. When a cell is low on fuel, AMPK shuts down processes that use energy and turns on processes that produce energy.Biologists have been studying how AMPK works for several decades and know that once it is activated, AMPK turns on a large number of genes by passing the "make more energy" message through numerous signaling cascades in the cell. What was not known, until now, was that AMPK also works via an epigenetic mechanism to slow down or stop cell growth.

Florida Institute of Technology assists licensing CDNI-Glu compound to UK company

As a national research university, Florida Institute of Technology not only involves its students in research, but also seeks to license and patent its many innovations. An example of recently licensed university technology is a chemical compound that facilitates the work of neuroscientists in the laboratory.Associate Professor Nasri Nesnas was familiar as a chemist with the chemical compound CDNI-Glu, a commonly used laboratory research tool. Most often, neuroscientists use it to study the brain's neural networks by improving the localization of synaptic stimulation

Resveratrol concentration impacts cancer risk mitigation: Study

Agricultural Research Service (ARS) chemist Thomas Wang, who specializes in cancer prevention research, has reported evidence that for some dietary compounds, length of exposure over time may be key to whether or not ingestion leads to a beneficial, or detrimental, effect.Scientists do not know exactly why one person develops cancer and another does not. But they do know that certain nutrients might increase or decrease cancer risk. There are "layers" of factors involved in the development of cancer, and Wang is studying the layers involving peoples' diet complexity and gene expression.

Cage type affects laboratory mice brain

Researchers at the University of Colorado's Anschutz Medical Campus have found the brains of mice used in laboratories worldwide can be profoundly affected by the type of cage they are kept in, a breakthrough that may require scientists to reevaluate the way they conduct future experiments.

ArmaGen uses BBB molecular Trojan horse platform technology to create brain penetrating form of human EPO

Human erythropoietin (EPO) is a potent neuroprotective agent for multiple brain disorders, including stroke, brain and spinal cord injury, and Parkinson's disease. However, EPO drug development for the brain is limited, because EPO does not cross the blood-brain barrier (BBB). In acute stroke or brain injury, the BBB is intact in the early hours after the insult when neuroprotection is still possible. Therefore, large molecule biopharmaceuticals such as EPO must be re-engineered to enable BBB transport.

Researchers discover potential way to stop tumor growth

Washington State University researchers have discovered a way to help cancer cells age and die, creating a promising avenue for slowing and even stopping the growth of tumors. "Hopefully, we can make cancer cells die like normal cells," says Weihang Chai, an assistant professor in the WSU School of Molecular Biosciences and WWAMI medical education program in Spokane. "Basically, you make the cancer cell go from immortal to mortal."

FDA can promote personalized medicine by identying gaps in laboratory operations: ACLA

The Food and Drug Administration can promote progress toward personalized medicine by approaching the oversight of laboratory developed tests (LDTs) in a focused, flexible, and balanced way according to the American Clinical Laboratory Association (ACLA). ACLA, which represents the nation's leading clinical laboratories, says that the factors supporting this approach include the growing role that such tests play in clinical decision making, especially in the area of new advanced diagnostics that derive from the mapping of the human genome and help fulfill the promise of personalized medicine.

Opinions: Science communication for development; International disaster response

"Helping developing countries communicate and use science is essential to international aid and diplomacy. The biggest single factor limiting developing countries' potential for achieving sustainable economic growth - or even attaining the Millennium Development Goals - is their ability to access and apply the fruits of modern science and technology," David Dickson, the director of SciDev.Net, writes in an editorial on the website.
