Scientists discover link between mutation in immune system gene and Alzheimer's disease

An international research team including scientists from the University of Toronto's Faculty of Medicine has discovered a link between a mutation in an immune system gene and Alzheimer's disease.

Study on effect of glucose on cancer growth in mice

An animal study conducted by researchers at Georgetown Lombardi Comprehensive Cancer Center raises questions about the consequences of diet - specifically glucose, the plant-based sugar that fuels cell life - on increased activity of an oncogene that drives tumor growth.

Myasthenia gravis therapies: an interview with Professor Daniel Drachman

Myasthenia gravis (MG) is an autoimmune disease that produces weakness and fatiguability of muscles. It affects between 1 and 7 people per 10,000, according to the best statistics.

Pig genes resemble human genes when associated with diabetes, obesity

Insights into the genetic code of pigs that reveal how the species evolved could improve the health of animals in future.

ALN RNAi therapeutic program represents novel approach for treatment of AAT deficiency

Alnylam Pharmaceuticals, Inc., a leading RNAi therapeutics company, announced today that it has presented new pre-clinical data with an RNAi therapeutic targeting alpha-1 antitrypsin (AAT) for the treatment of liver disease associated with AAT deficiency. These data were presented at the 63rd Annual Meeting of the American Association for the Study of Liver Diseases (AASLD, "The Liver Meeting") held November 9-13, 2012 in Boston.

New gene delivery vehicle opens route to the heart of cells in solid tumors

There are plenty of effective anticancer agents around. The problem is that, very often, they cannot gain access to all the cells in solid tumors. A new gene delivery vehicle may provide a way of making tracks to the heart of the target.

Scientists eliminate metastasis in laboratory experiments

In laboratory experiments, scientists have eliminated metastasis, the spread of cancer from the original tumor to other parts of the body, in melanoma by inhibiting a protein known as melanoma differentiation associated gene-9 (mda-9)/syntenin. More than 1 million cases of skin cancer are diagnosed each year in the U.S., and melanoma is the deadliest form.

Medulloblastomas that arise from different cell types might require personalized treatments

Cancers arise when a normal cell acquires a mutation in a gene that regulates cellular growth or survival. But the particular cell this mutation happens in-the cell of origin-can have an enormous impact on the behavior of the tumor, and on the strategies used to treat it.

Study reveals how interneurons navigate during cerebral cortex development

As the brain develops, each neuron must find its way to precisely the right spot to weave the intricate network of links the brain needs to function. Like the wiring in a computer, a few misplaced connections can throw off functioning for an entire segment of the brain.

Biofactory introduces FastFraX FMR1 Identification Kit at MEDICA 2012

The Biofactory, a biomedical incubator based in Singapore, has launched a new genetic test at MEDICA 2012, the world's largest medical trade fair. Called FastFraX, this genetic test is able to effectively screen for Fragile X Syndrome (FXS), a genetic condition that is the most common form of inherited intellectual disability.

Gene variants involved in glutamatergic transmission appear to increase risk of depression

Researchers using a new approach to identifying genes associated with depression have found that variants in a group of genes involved in transmission of signals by the neurotransmitter glutamate appear to increase the risk of depression.

Scientists reveal timing mechanism in formation of vertebrae

As they develop, vertebrate embryos form vertebrae in a sequential, time-controlled way. Scientists have determined previously that this process of body segmentation is controlled by a kind of "clock," regulated by the oscillating activity of certain genes within embryonic cells. But questions remain about how precisely this timing system works.

Atpif1 gene regulates heme synthesis in red blood cell formation

Scientists at the University of Georgia, Harvard Medical School and the University of Utah have discovered a new gene that regulates heme synthesis in red blood cell formation. Heme is the deep-red, iron-containing component of hemoglobin, the protein in red blood cells responsible for transporting oxygen in the blood.

Taste receptor governs respiratory infection susceptibility

The bitter taste receptor TAS2R38 may play a role in innate defense, say researchers, who have found that variations in the TAS2R38 gene may regulate susceptibility to respiratory infection.

Weight-based ribavirin undertreats African–American HCV patients

African–Americans with hepatitis C virus genotype 1 infections have lower ribavirin plasma exposures than Caucasian Americans when treated with weight-based ribavirin plus peginterferon.

Whole genome sequencing could become prenatal standard of care

Whole genome sequencing of the DNA code of prenatal samples accurately and quickly identifies the location of chromosomal abnormalities, and could become a prenatal standard of care, researchers propose.

Longer looks: People with mental disabilities have a vote; Genome sequencing raises hope - also anxiety

I may get Alzheimer's disease, I was told after getting my DNA analyzed. I could suffer the consequences of an abnormal blood clot in my heart or my brain. Or perhaps I'll suffer from a disease called primary myelofibrosis that's caused by an overactive bone marrow. All of these were possible outcomes, based on my genetic profile. In each case, the test only gives an increased risk for disease, not a definitive diagnosis.

UIC researchers develop transgenic Alzheimer's mouse with apoE4 gene

Researchers at the University of Illinois at Chicago College of Medicine have developed a transgenic mouse that carries a human gene known to increase risk of Alzheimer's 15-fold. This new mouse mimics the genetics of the human disease more closely than any of the dozen existing mouse models and may prove more useful in the development of candidate drugs to prevent or treat the disease.

Plexxikon updates Zelboraf Phase 1 data on BRAF V600E mutation-positive melanoma

Plexxikon today announced that updated Phase 1 clinical data of Zelboraf (vemurafenib) were presented at the Society for Melanoma Research (SMR) 2012 Congress, held November 8-11 in Los Angeles, CA.
