Proteins are complex molecules that are made up of amino acids. They can be found in every cell in the body, and carry out vital processes that keep human beings alive. Mutations in proteins can lead to a multitude of diseases, the most common being cancer.

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.

Ultrafast laser detection of cancer cells also may improve understanding of stem cells

To investigate tumors, pathologists currently rely on labor-intensive microscopic examination, using century-old cell-staining methods that can take days to complete and may give false readings.

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.

Docosahexaenoic acid may protect against the accumulation of a protein believed to be linked to Alzheimer's disease

Docosahexaenoic acid (DHA), an omega-3 fatty acid, may protect against the accumulation of a protein believed to be linked to Alzheimer's disease, according to the results of a new study published in the March 30, 2005 issue of The Journal of Neuroscience. The study used Martek DHA, which is produced from microalgae.

How does the body keep the number of neutrophils produced constant in the blood?

Every day, the human body manufactures and destroys about 100 billion neutrophils- the most common type of white blood cell and one of the most highly-produced cells. Neutrophils live about eight hours, are bacteria-eaters and are a key component of the immune system. Without them, the body can be subject to life-threatening infection.

Study suggests combination therapy could stop spread, halt growth of melanomas

Researchers at Penn State College of Medicine have identified the mechanism by which the most mutated gene in melanoma, called v599EB-Raf, aids melanoma tumor development demonstrating its importance as a therapeutic target.

Green alga closes wounds by means of enzymatic activation of a cross-linking protein

A small wound is painful, but is normally not a problem. Like all multicellular organisms, our bodies form new tissue around the damaged cells. Single-celled organisms cannot do this. In order to survive an injury, they have to quickly repair the cell itself. Large single-celled organisms, such as the green alga Caulerpa taxifolia, which can be several meters long, are especially at risk for injuries.

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).

Structure of key protein in innate immune response

In a report published in the Journal of Biological Chemistry, scientists in Korea announced their elucidation of three-dimensional structure of CD14 and showed how it is perfectly suited to bind to certain bacterial products.

New research in mice sheds light on the causes behind male infertility

For 40 percent of the estimated six million American couples battling infertility, the problem lies with the man. But help may be on the way.

Why respiratory viral infections are often more severe in people with asthma

Lung cells from asthma sufferers fail to invoke critical anti-viral defenses when infected with the common cold virus, according to a study in the March 21 issue of The Journal of Experimental Medicine. These results could help explain why respiratory viral infections are often more severe in people with asthma and how infection can trigger asthma attacks.

Scientists provide insight into the molecular mechanisms behind Listeria monocytogenes

When the bacterium Listeria monocytogenes invades the body, it commandeers its host cell's actin cytoskeleton to invade other cells. In a report published in the Journal of Biological Chemistry, a group of scientists provide insight into the molecular mechanisms behind this infection technique.

Scientists find microRNA regulates Ras cancer gene

Research in the laboratory of Assistant Professor Frank J. Slack at Yale University has identified a new way that a familiar gene is regulated in lung cancer, presenting new possibilities for diagnosis and treatment. The work is reported in March issues of the journals Cell and Developmental Cell.

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.

UK grows stem cells free of animal products

Dr Paul de Souza and scientists at the Roslin Institute have successfully created human cells without using animal products.

Link between C-reactive protein, heart disease and stroke

The cells that line the arteries are able to produce C-reactive protein, according to a study funded by the National Institutes of Health and published in the April issue of American Journal of Pathology.

Study reveals how brain's immune system fights viral encephalitis

The findings, published as the cover study in the latest issue of Virology, show that proteins in neurons fight the virus at multiple stages - by preventing the formation of viral RNA and proteins, and blocking the virus' release, which could infect other cells in the brain.
