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.

Researchers detail molecular images of a piece of the spike-shaped protein that the SARS virus uses initiate the first stages of infection

Researchers have determined the first detailed molecular images of a piece of the spike-shaped protein that the SARS virus uses to grab host cells and initiate the first stages of infection.

Human fat cells produce a protein that is linked to both inflammation and an increased risk of heart disease and stroke

Researchers at The University of Texas M. D. Anderson Cancer Center and The University of Texas Health Science Center at Houston have found that human fat cells produce a protein that is linked to both inflammation and an increased risk of heart disease and stroke.

Molecular pathway in mice that makes prostate cells vulnerable to cancer-causing oxygen damage

Scientists from Maryland and New Jersey have identified a molecular pathway in mice that makes prostate cells vulnerable to cancer-causing oxygen damage.

Study suggests chronic infections may create autoimmune response

New research finds the human immune system has foregone evolutionary changes that would allow it to produce better antibodies in less time because the improved antibodies would be far more likely to attack the body's own tissues.

Researchers selectively knock out memory associations connected with receiving cocaine

Addicts crave drugs and suffer relapse not just because of the alluring high of drugs, but also because they are compelled by the powerful, haunting memory associations with the environment surrounding their drug taking. Thus, treatments that could eliminate those memory associations could prove effective in treating addiction, researchers believe.

New and unusual class of genes plays an important role in the development of chronic lymphocytic leukemia

The study found that the loss of two genes for producing small molecules known as microRNAs enables damaged cells to survive, rather than normally self-destructing before they become cancerous.

Microtubules critical to development of mental disorders

Neuroscientists at the University at Buffalo have shown in two recently published papers that destabilization of structures called microtubules, intracellular highways that transport receptors to their working sites in the brain, likely underlie many mental disorders and could be promising targets for intervention.

Cellular mechanism discovery could lead to new treatments for rheumatoid arthritis, multiple sclerosis and Crohn's disease

A major finding by researchers at the La Jolla Institute for Allergy & Immunology (LIAI) has identified a previously unknown cellular mechanism that acts as an off switch for immune system function.

Translation elongation factor eEF1A2 is is a potential oncogene that is overexpressed in two-thirds of breast tumors

The tissue-specific elongation factor eEF1A2 might be an oncoprotein involved in breast cancer.

Nuclear receptor proteins could change anti-inflammatory treatments

Several nuclear receptor proteins appear to overlap in their ability to exert anti-inflammatory effects, according to new research by scientists at the University of California, San Diego (UCSD).

Amantadine resistant avian influenza viruses more common in Southeast Asia than North America

Resistance to the antiviral drug amantadine is spreading more rapidly among avian influenza viruses of H5N1 subtype in Southeast Asia than in North America, according to the study done by investigators at St. Jude Children's Research Hospital.

Clioquinol appears to block the genetic action of Huntington's disease

Clioquinol, an antibiotic that was banned for internal use in the United States in 1971 but is still used in topical applications, appears to block the genetic action of Huntington's disease in mice and in cell culture, according to a study reported by San Francisco VA Medical Center (SFVAMC) researchers.

Key cellular switch that controls glucose production in liver cells

In many patients with type 2 diabetes, the liver acts like a sugar factory on overtime, churning out glucose throughout the day, even when blood sugar levels are high. Scientists at the Salk Institute for Biological Studies discovered a key cellular switch that controls glucose production in liver cells.

Unexpected link between the viruses that cause feline and human AIDS

A University of Florida researcher has discovered an unexpected link between the viruses that cause feline and human AIDS: Cats vaccinated with an experimental strain of the human AIDS virus appear to be at least as well-protected against the feline version of the disease as those immunized with the vaccine currently used by veterinarians.

Why do estrogen-dependent breast-cancer cells grow and spread rapidly?

Researchers at the University of Illinois at Urbana-Champaign say it may be because estrogen virtually eliminates levels of a vitally important regulatory protein.

Scientists characterize the most infectious prion protein particles

A new study of prions - apparently malformed proteins that initiate deadly brain diseases such as Creutzfeldt-Jakob disease in humans - has yielded surprising information about how the size of prions relates to their infectivity.

Diabetics with fatty livers could benefit from diet rich in soy protein

According to a group of researchers from Mexico they have discovered that a diet rich in soy protein may alleviate fatty liver, a disease which often accompanies diabetes.

Depression may hasten the progression of heart disease

In a study of 32 people with heart failure, the 14 patients who felt the most depressed had nearly twice the levels of this protein in their blood.

Stressgen granted new U.S. patent for treatment of Hepatitis B

Stressgen Biotechnologies announced today that the U.S. Patent and Trademark Office granted Patent Number 6,921,534 covering fusion protein compositions comprised of a hepatitis B virus (HBV) antigen fused to a heat shock protein (Hsp), as well as DNA encoding such fusion proteins, and methods of treating an HBV infection using these fusion proteins.

New study dispels role of B vitamins in preventing heart attacks

According to the findings of a new study, by giving B vitamins to heart attack survivors their risk of having another attack is not reduced, and it may in fact do more harm than good.
