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.

Research on Reaper protein provides new treatment strategies for cancer

Our cells live ever on the verge of suicide, requiring the close attention of a team of molecules to prevent the cells from pulling the trigger. This self-destructive tendency can be a very good thing, as when dangerous precancerous cells are permitted to kill themselves, but it can also go horribly wrong, destroying brain cells that store memories, for instance. Rockefeller University scientists are parsing this perilous arrangement in ever finer detail in hopes that understanding the basic mechanisms of programmed cell death, or apoptosis, will enable them eventually to manipulate the process to kill the cells we want to kill and protect the ones we don't.

Scientists find potential Achilles Heel in JC polyomavirus

The JC polyomavirus doesn't strike very often, but it's a mean bug that preys on people with weakened immune systems, including people with AIDS, and almost always kills them. Now an international team of scientists at Brown University, the University of T-bingen in Germany, and Imperial College in London has found a potential Achilles Heel and painted a target on it: The virus must bind to a very specific sugar molecule dangling from the side of the brain cells it attacks.

Researchers identify common link among malignant tumor types in all grades of cancer

Researchers from Mount Sinai School of Medicine, in collaboration with investigators of the National Institute of Health and Medical Research (INSERM) of France led by Nicolae Ghinea, PhD, have found a common link among several malignant tumor types in all grades of cancer. This breakthrough may ultimately provide a new diagnostic or therapeutic target to detect cancer early or stop tumor growth.

Menopausal estrogen replacement therapy speeds growth of ovarian cancer

Estrogen therapy used by menopausal women causes a type of ovarian cancer to grow five times faster, according to a new study by researchers at the University of Colorado Cancer Center.

Study: p63 gene stifles spread of cancer

Long overshadowed by p53, its famous tumor-suppressing sibling, the p63 gene does the tougher, important job of stifling the spread of cancer to other organs, researchers at The University of Texas MD Anderson Cancer Center report in the Oct. 21 issue of Nature.

Dopamine vital for rhythmic expression in specific brain regions: Research

Daily sleeping and eating patterns are critical to human well-being and health. Now, a new study from Concordia University has demonstrated how the brain chemical dopamine regulates these cycles by altering the activity of the "clock-protein" PER2. Published in the Journal of Neuroscience, these findings may have implications for individuals with Parkinson's Disease with disrupted 24-hour rhythms of activity and sleep.

A universal cancer treatment for a universal cancer marker

A latest study shows that a hormone receptor normally confined to the reproductive organs is found in malignant tumors in many parts of the body. Researchers from the Mt. Sinai School of Medicine in New York City explained that this may mean a new target for the early diagnosis and treatment of cancer. The study was published in the latest issue of The New England Journal of Medicine.

New solutions to make protein-deficient Indian schoolchildren eat soy products

University of Illinois scientists think they have solved an interesting problem: how to get protein-deficient Indian schoolchildren to consume soy, an inexpensive and complete vegetable protein. What's more, they've joined forces with an Indian foundation that can get the high-protein soy snack they've developed into the hands of 1.2 million hungry kids who need it.

First in vivo screening system for complete human nuclear hormone receptor family

The InDanio screening system can be used, for example, to functionally characterize 'orphan' receptors - those for which their natural ligands or specific function are unknown - and thus qualify them as potential targets for drug discovery. The system can also be used to screen compound libraries in order to identify and refine potential new drugs that target NR proteins.

MU researchers examine Aspergillus fumigatus to find cure for fungus, parasite

If finding the cure for a fungus and parasite that affects millions of people were the subject of a detective show, University of Missouri Chemistry Professor John Tanner would be the forensic expert in the lab, using high-tech equipment to make a model that could eventually solve the crime.

Carbon dioxide plays a role in gene regulation: Research

UCD Conway researchers have found that carbon dioxide (CO2) is not only involved in climate change and a waste product of respiration in cells but also plays an active role in regulating the genes involved in inflammation and innate immunity. Their research findings were highlighted recently in the The Journal of Immunology.

New approaches to explore causes of autoimmunity and immune deficiency diseases

A newly identified regulatory process affecting the biology of immune system T cells should give scientists new approaches to explore the causes of autoimmunity and immune deficiency diseases.

Study reveals how cells crank up cancer activators

A new technique that searches blood for the tiniest remnants of broken down proteins has revealed new information about how cells crank up cancer activators called proteases. The results improve researchers' understanding of the mechanics of breast cancer and point to where to look for possible indicators of early disease.

UH researchers to explore role of Vitamin D in esophageal cancer prevention

In a first-of-its-kind clinical trial, physicians at University Hospitals (UH) Case Medical Center who are Case Western Reserve University School of Medicine researchers are exploring the role of Vitamin D in preventing esophageal cancer.

Jefferson researchers progress in understanding mechanism behind systemic fibrotic disorder

Scientists from the Jefferson Institute of Molecular Medicine of Thomas Jefferson University are now several steps closer to understanding the mechanism behind a novel systemic fibrotic disorder that affects some patients with renal insufficiency who receive imaging contrast agents for MRI. Two of their studies on the disorder appear together in the November issue of the Annals of Rheumatic Diseases.

Ceregene commences enrollment in CERE-120 Phase 2b study for Parkinson's disease

Ceregene, Inc., a biopharmaceutical company, announced today that enrollment has begun in a new double-blind sham surgery-controlled Phase 2b study evaluating CERE-120 in Parkinson's disease patients. CERE-120 is a gene therapy product that delivers the neurotrophic factor neurturin to degenerating or dying dopamine neurons. Data from the first Phase 2 clinical trial of CERE-120 are being published later this year in Lancet Neurology (to appear online October 21, 2010).

Protein hormone inhibits leptin-induced migration of liver cancer cells

A research team from Emory University School of Medicine investigated the role between adiponectin and leptin in obesity-related carcinogenesis. Their findings, published in the November issue of Hepatology, suggest that the protein hormone adiponectin has potential for inhibiting the oncogenic actions of leptin, namely in hepatocellular carcinoma (HCC), and could offer a promising therapy for the disease.
