CD22 protein could prove to be important new target for anti-cancer therapy

A team of UC Davis investigators has discovered a protein on the surface of lung cancer cells that could prove to be an important new target for anti-cancer therapy. A series of experiments in mice with lung cancer showed that specific targeting of the protein with monoclonal antibodies reduced the size of tumors, lowered the occurrence of metastases and substantially lengthened survival time.

Soy products do not prevent onset of vasomotor symptoms in women

A team of investigators led by UC Davis found that eating soy products such as soy milk and tofu did not prevent the onset of hot flashes and night sweats as women entered menopause.

New video-protocol details steps to generate human iPSCs from peripheral blood cells

Stem cells are a valuable resource for medical and biological research, but are difficult to study due to ethical and societal barriers. However, genetically manipulated cells from adults may provide a path to study stem cells that avoid any ethical concerns. A new video-protocol in JoVE (Journal of Visualized Experiments), details steps to generate human induced pluripotent stem cells (iPSC) from cells in the peripheral blood.

XJB-5-131 compound suppresses symptoms of Huntington's in mice

There's new hope in the fight against Huntington's disease. A group of researchers that includes scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have designed a compound that suppresses symptoms of the devastating disease in mice.

PET scans allow scientists to study link between caffeine and neurodegenerative disorders

Molecular imaging with positron emission tomography (PET) has enabled scientists for the first time to visualize binding sites of caffeine in the living human brain to explore possible positive and negative effects of caffeine consumption.

Researchers unlock complex cellular mechanics that instruct glial progenitor cells to divide

In a new study appearing this month in the Journal of Neuroscience, researchers have unlocked the complex cellular mechanics that instruct specific brain cells to continue to divide. This discovery overcomes a significant technical hurdle to potential human stem cell therapies; ensuring that an abundant supply of cells is available to study and ultimately treat people with diseases.

MH6 vaccine shows promise in treating meth addiction

Scientists at The Scripps Research Institute (TSRI) have performed successful tests of an experimental methamphetamine vaccine on rats. Vaccinated animals that received the drug were largely protected from typical signs of meth intoxication.

Study describes role of TFIIB protein in helping cells repair DNA damage

In a new study, University at Buffalo scientists describe the role that a protein called TFIIB plays in helping cells repair DNA damage, a critical function for preventing the growth of tumors.

Study identifies monoacylglycerol lipase as new therapeutic target to treat Alzheimer's

Research led by Chu Chen, PhD, Associate Professor of Neuroscience at LSU Health Sciences Center New Orleans, has identified an enzyme called Monoacylglycerol lipase (MAGL) as a new therapeutic target to treat or prevent Alzheimer's disease.

Oskar gene emerged far earlier in insect evolution than previously believed

Harvard scientists have solved the long-standing mystery of how some insects form the germ cells - the cellular precursors to the eggs and sperm necessary for sexual reproduction - and the answer is shedding new light on the evolutionary origins of a gene that had long been thought to be critical to the process.

Apolipoprotein E plays a major role in maintaining arterial softness

Arterial stiffening has long been considered a major risk factor for cardiovascular disease. Keeping arteries soft and supple might reduce disease risk, but the mechanisms of how arteries stave off hardening has remained elusive.

High blood cholesterol far more common than previously recognized

High blood cholesterol, a serious hereditary disease, is far more common than previously recognised and not treated sufficiently.

NJH researchers discover novel target for treatment of food allergies

Researchers at National Jewish Health have discovered a novel target for the treatment of food allergies. Erwin Gelfand, MD, and his colleagues report in the October 2012 issue of the Journal of Allergy and Clinical Immunology that levels of the enzyme Pim 1 kinase rise in the small intestines of peanut-allergic mice. Inhibiting activity of Pim 1 markedly reduced the allergic response to peanuts.

Study explores impact of IL1β on brain function alterations associated with schizophrenia

There are a growing number of clues that immune and inflammatory mechanisms are important for the biology of schizophrenia. In a new study in Biological Psychiatry, Dr. Mar Fatjó-Vilas and colleagues explored the impact of the interleukin-1β gene (IL1β) on brain function alterations associated with schizophrenia.

Study finds link between severe sepsis and chronic diseases

It's a major cause of death, yet few of us have ever heard of it. Sepsis occurs when a patient's immune system overreacts to an infection, triggering a potentially fatal, system-wide inflammation. Severe sepsis strikes about 750,000 Americans each year, most of them older and often ill, with as many as half of these patients dying as septic shock shuts down their organs. Furthermore, patients in many Southern states are about twice as likely to develop sepsis for reasons unknown.

Blocking hyaluronidase activity can help repair brain damage associated with MS

Researchers at Oregon Health & Science University have discovered that blocking a certain enzyme in the brain can help repair the brain damage associated with multiple sclerosis and a range of other neurological disorders.

Dysfunction in SRGAP3 protein causes developmental brain disorders

A new research discovery has the potential to revolutionize the biological understanding of some childhood psychiatric disorders. Specifically, scientists have found that when a single protein involved in brain development, called "SRGAP3," is malformed, it causes problems in the brain functioning of mice that cause symptoms that are similar to some mental health and neurological disorders in children.

CSHL scientists discover new way to specifically target and kill cancer cells

Cancer cells grow fast. That's an essential characteristic of what makes them cancer cells. They've crashed through all the cell-cycle checkpoints and are continuously growing and dividing, far outstripping our normal cells. To do this they need to speed up their metabolism.
