Protein News and Research

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 insights into how tumors neutralize CD8 T cells

Scientists have speculated that this may be because the immune response is not strong enough, or because it does not last long enough to have an effect. Hence the increasing efforts to develop cancer vaccines that induce, strengthen, and increase the duration of immunological attack against cancer cells.

Cancer-specific protein offers new target for the development of melanoma vaccine

Scientists from the Cancer Vaccine Collaborative (CVC) have discovered that the cancer-specific protein, SSX-2, induces a spontaneous immunological reaction against cancer cells in melanoma patients, offering a new target for the development of a therapeutic melanoma vaccine. SSX-2 is the prototype of the SSX family, and is part of a larger group of proteins known as cancer/testis (CT) antigens.

Three hours exercise reduces risk of breast cancer

Three hours of moderate exercise per week significantly reduced circulating estrogens in postmenopausal women, according to a new study published in the current issue of Cancer Research. The finding may explain why women who exercise regularly lower their risk for breast cancer.

Proteomics techniques to find a possible predictor of response in a chemoprevention trial

Using new technology associated with the study of proteins, or proteomics, scientists at the National Cancer Institute (NCI), part of the National Institutes of Health (NIH), and their colleagues have made a step toward predicting which people with familial adenomatous polyposis (FAP), an inherited condition that often leads to colon cancer, will respond to the prevention drug celecoxib.

Scientists discover gene for Parkinson's disease

UCL scientists have discovered a new gene implicated in the early development of Parkinson's disease. In a study of families with early onset disease, Professor Nick Wood and colleagues at University College London's Institute of Neurology identified a novel gene which produces a malfunctioning protein that could pave the way for new treatments for Parkinson sufferers.

Ground-breaking discoveries relating to the formation of kidney stones

Ground-breaking discoveries relating to the formation of kidney stones have earned Flinders University researchers a grant of more than $1.2 million (Australian) from the National Institutes of Health (NIH), the major funding body for medical science in the United States.

Protein identification gets a speed boost

But the labor intensity of the procedure is now a thing of the past for researchers in the Oregon Health & Science University School of Medicine. The Proteomics Shared Resource, an unassuming but state-of-the-art lab on the fifth floor of OHSU's Medical Research Building, can process more than three times as many protein samples in half a day, and much of it can be done by one person.

Cinnamon's role as an insulin substitute in type II diabetes

Cinnamon may be more than a spice – it may have a medical application in preventing and combating diabetes. Cinnamon may help by playing the role of an insulin substitute in type II diabetes, according to cellular and molecular studies at the University of California, Santa Barbara, Iowa State University and the U.S. Department of Agriculture.

Ultrasound therapy does nothing to help an injured skeletal muscle heal any faster

Although ultrasound is one of the most frequently prescribed treatments for one of the most common sport and athletic injuries – skeletal muscle contusions – there's really no good scientific evidence showing that it treats injured muscles effectively, said Steven Devor, the study's lead author and an assistant professor of sport and exercise sciences at Ohio State University.

Autism gene discovered

Researchers at Mount Sinai School of Medicine are first to strongly link a specific gene with autism. While earlier studies have found rare genetic mutations in single families, a study published in the April issue of the American Journal of Psychiatry is the first to identify a gene that increases susceptibility to autism in a broad population.

New tool for study of carbohydrates could aid drug research

While many dieters are trying to cut carbs, a University of New Hampshire (UNH) biochemist has invented a way to capture them so scientists can more easily study their structure.

Researchers have developed a new method for finding antigens

Researchers at National Jewish Medical and Research Center have developed a method for finding the molecular targets of the immune system, known as antigens.

Protein sequences harder to predict than originally thought

Scientists have believed for decades that the sequencing of the human genome would automatically yield the sequences of proteins, the functional products of genes, and thus lead to the unraveling of the mechanisms behind human cell biology and disease.

Vitamin C can reduce levels of C-reactive protein, a marker of inflammation and chronic disease

Vitamin C supplements can reduce levels of C-reactive protein, a marker of inflammation and chronic disease risk in humans, according to a new study led by researchers at the University of California, Berkeley.

Gene therapy helps damaged heart cells regain strength and beat normally

Researchers at Jefferson Medical College and Duke University have used gene therapy to help damaged heart cells regain strength and beat normally again in the laboratory. The work takes the scientists one step closer to eventual clinical trials in humans.

New research into Human Papilloma Virus (HPV) and Cervical Cancer

Cervical cancer is the second-most prevalent cancer in women and, despite encouraging improvements in screening leading to earlier detection, cervical cancer still kills many women every year. The risk of cervical cancer is increased by infection with certain types of human papilloma virus (HPV).

Researchers pinpoint pathway to muscle regeneration

A team including MDA grantee Gordon Lynch in the Department of Physiology at the University of Melbourne in Victoria, Australia, found that a biological signaling pathway may help explain why mice with Duchenne muscular dystrophy (DMD) can regenerate their muscles much better than can humans with the same disease.

New nose cancer test kit promises to simplify the process and speed cancer testing

Inflexion a Singapore based offshoot of Nanyang Technological University has announced a new kit to test for and diagnose nose cancer. The kit was prepared some 3 years ago and had been forgotten until 3 young entrepreneurs realised it's commercial potential.

Researchers isolate gene responsible for Chron's disease

Crohn's disease is an inflammatory bowel disease and its prevalence is increasing in industrialized nations. Existing treatments are considered unsatisfactory, often requiring recurring hospitalization and surgeries.

New process to extract proteins from membranes by using chemicals

Proteins are complex compounds that are essential for the growth and repair of tissue. While scientists understand much about the structure and stability of water-soluble proteins that ‘float’ around in humans, they know very little about the shape and stability of proteins that are embedded, or folded, into the lipid membrane of cells. Such membrane proteins make up about 30 percent of all proteins in the body.
