Test that will prevent the needless loss of the thyroid gland in people with the noncancerous condition

New research suggests that physicians can distinguish between a type of thyroid cancer and an identical-looking, non-cancerous thyroid condition by simply determining the activity of three genes.

Genome in gut bacterium key to intestinal health

A bacterium that lives in the human gut adaptively shifts more than a quarter of its genes into high gear when its host's diet changes from sugar to complex carbohydrates.

New directions toward the treatment of bipolar disorder

While lithium treatment has proven to be a godsend for many of the two million Americans with bipolar disorder, it is not without its downside. People on the drug may develop hypothyroidism, tremors, cognitive impairment, and excessive thirst and urination and gain weight.

Gene linked to bone mineral density

Sequenom has announced the discovery of a genetic variation in the gene encoding phosphodiesterase 4D (PDE4D) that is believed to affect osteoporosis risk. Fragility fractures caused by osteoporosis are a major cause of morbidity and mortality in the aging population.

Antibodies from tobacco plants protect against anthrax

Scientists have produced, in tobacco plants, human antibodies that could be used to treat anthrax exposure. They reported their findings at the 2005 American Society for Microbiology Biodefense Research Meeting.

Gene named ATBF1 may contribute to the development of prostate cancer

A gene named ATBF1 may contribute to the development of prostate cancer through acquired mutations and/or loss of expression, according to research at Emory University School of Medicine and its Winship Cancer Institute.

Scientists have found genetic regions that, when defective, allow the immune system to attack the pancreas

Scientists at Joslin Diabetes Center have found genetic regions that, when defective, allow the immune system to attack the pancreas -- the first in a series of mis-steps that lead to type 1 diabetes. Armed with these findings, published yesterday, March 22, in the journal Immunity, the researchers are now trying to hone in on the exact genes involved, in mice and in human patients.

Preventing eye disease in retinitis pigmentosa

Retinitis pigmentosa (RP) is an inherited eye disease that causes visual disability leading to blindness. Over the last 15 years, researchers have pinpointed defects in dozens of genes causing different forms of RP.

Tiny scaffolding allows stem cells to become working fat cells

Researchers here have used a new microscopic, three-dimensional scaffolding to coax mouse stem cells to transform themselves into fat cells, and then to function identical to how fat cells naturally do in the body.

Genes TEL2 and MYC cooperate with each other to promote pediatric cases of the immune system cancer B-cell lymphoma

The genes TEL2 and MYC cooperate with each other to promote pediatric cases of the immune system cancer B-cell lymphoma. This finding, from investigators at St. Jude Children's Research Hospital, is published in the current issue of Molecular Cell Biology (MCB).

Findings are expected to yield new diagnostic and therapeutic tools in the battle against cancer

New laboratory findings at the University of Illinois at Chicago suggest that what lies outside cancer cells is at least as important as the genes inside in explaining a tumor's malignancy.

African genome research given impetus

Millions of victims in Africa, die each year from preventable diseases like tuberculosis and malaria and researchers say only a relatively small proportion of money is spent on developing vaccines, much more is spent on drugs aimed at tackling diseases more prevalent among rich, Western consumers.

Genomic analysis may one day be a primary diagnostic tool for physicians deciding on a course of treatment for trauma

The researchers showed that state-of-the-art techniques for rapidly analyzing changes in activity of all human genes will likely produce useful insights into the health of critically ill patients. The findings, which are available online and will be published in the March 29 issue of the Proceedings of the National Academy of Sciences, make it possible for physicians to begin answering important questions about critical care through genomic analysis.

Chemists say they have identified a gene that appears to play a key role in the development of type 1 diabetes

In the current study, the researchers focused on the formation of the MIF protein (macrophage migration inhibitory factor), a proinflammatory protein that they showed in previous studies is elevated in diabetic animals and may be involved in the cascade of immunological events that leads to the destruction of the pancreas and the subsequent onset of type 1 diabetes.

RNA loops and knots guide genetic modifications

University of Connecticut Health Center scientist, Robert Reenan, has uncovered new rules of RNA recoding - a genetic editing method cells use to expand the number of proteins assembled from a single DNA code.

Discovery of a single mutation responsible for a number of blood disorders

Myeloproliferative disorders form a range of haematological malignant diseases, with three main members: polycythaemia vera, essential thrombocythaemia, and idiopathic myelofi- brosis. The disorders are characterised by overactive production of blood cells and can lead to thrombosis, haemorrhage or acute myeloid leukaemia.

Major milestone in identifying and creating a register of genes involved in multiple sclerosis

For the first time in this disease area, researchers at the SGI have identified 80 genes involved in the inflammatory and neuro-degenerative pathways of MS, based on a 40% genome scan comparing the genetic profile of a total of 1,800 people with MS and healthy individuals in different populations.

X-Chromosome has the big story!!

The human genome is said by some to be the "book of life," and the X-chromosome a large part of the the plot. A team of genome researchers have described the nature of this mysterious "chapter" in the DNA story.

RNAi Consortium to accelerate genetic research

Whitehead Institute has joined ten other leading biomedical organizations in an $18 million, three-year public-private consortium that will create a comprehensive library of gene inhibitors to be made available to the entire scientific community.

Mountaineering doctors hike medicine to new heights with Xtreme Everest

Doctors working at the edge of extreme are set to climb the world’s tallest mountain to look death in the face – and take its pulse. The medical research team will make the first ever measurements of blood oxygen in the ‘death zone’, at altitudes above 8,000 metres where the human body has struggled - and frequently failed - to survive.
