Now, in research that may have implications for novel disease therapies, Rockefeller University scientists have shown that the balance of two different versions of these Fc? receptors - activating versus inhibitory - appears to affect production of an important set of genes, called interferon-response genes, including one believed to play an important role in autoimmunity and cancer. The researchers believe that manipulating the ratio of these receptors could lead to new therapies for these disorders. ...> Full Article Small RNAs Can Prevent Spread of Breast Cancer (1/12/2008)Researchers have identified small pieces of ribonucleic acid (RNA) that suppress the spread of breast cancer to the lungs and bone.

Progress is being held back however by the difficulty testing new therapies on human heart tissue, with animal models being only of limited value owing to differences in structure and activity. The only solution in the absence of real human models is to create computerised "in-silico" models that simulate the real heart and enable possible drugs and therapies to be tested without risk to people. Although this is still some way off becoming a reality, substantial progress has been made, and the next steps were plotted at a major workshop held recently by the European Science Foundation (ESF). ...> Full Article The great white hope (1/10/2008)

However, working with mice, VIB scientists connected to the Katholieke Universiteit Leuven have been able to prevent muscular tissue with severe hypoxia from dying. The muscles seem to 'adapt' to the lack of oxygen - a metabolic tour de force that animals also use when hibernating, but that has remained a mystery until now. ...> Full Article Researchers find Sept 11 stress increases risk of heart problems (1/9/2008)Study is first to demonstrate impact of terrorist attacks on cardiac health ...> Full Article Clinical Trial to Assess Effects of Drug Regimens on HIV-Related Neuro-Cognitive Impairment (1/9/2008)A clinical trial is being conducted by researchers at UCSD's HIV Neurobehavioral Research Center (HNRC) to discern which antiretroviral treatments are most effective in treating HIV-related disease in the brain and central nervous system.

The research, which appears in the January 2 advance online issue of The Journal of Clinical Investigation, could lead to new strategies for treating Parkinson's and other neurodegenerative diseases. ...> Full Article New strategies work to put cancer on the firing line (1/6/2008)
Gene Protects Newborns from Killer Respiratory Disease (1/5/2008)Yale School of Medicine researchers have isolated a gene that helps protect newborns from the most common respiratory cause of infant death in the United States-respiratory distress syndrome. ...> Full Article More Teen Women Battling Heart Disease (1/5/2008)At the age of 18, most young women are embarking on adulthood without a care in the world-health included. ...> Full Article 'Electronic switch' opens doors in rheumatoid joints (1/5/2008)A breakthrough in understanding the way atoms move across cell membranes in the human body could pave the way for the development of new treatments for inflammatory diseases such as rheumatoid arthritis. ...> Full Article Scientists Studying the Effects of High Dose Vitamin C on Non-Hodgkin Lymphoma Patients (1/5/2008)Vitamin C's low toxicity lends high hopes to pioneering study ...> Full Article Study examines genetic defects linked to body abnormalities in patients with childhood cancer (1/4/2008)Children with cancer have a higher prevalence of body abnormalities, such as asymmetric lower limbs and curvature of the spine, suggesting that the genetic defect responsible for the abnormality may play a role in the development of cancer, according to a study in the January 2 issue of JAMA. ...> Full Article Research Unveils New Hope for Deadly Childhood Disease (1/4/2008)Investigators have uncovered a promising drug therapy that offers a ray of hope for children with Batten disease - a rare neurodegenerative disease that strikes seemingly healthy kids, progressively robs them of their abilities to see, reason and move, and ultimately kills them in their young twenties. ...> Full Article Scientist produces first-ever study linking increased mortality specifically to carbon dioxide emissions (1/4/2008)A Stanford scientist has spelled out for the first time the direct links between increased levels of carbon dioxide in the atmosphere and increases in human mortality, using a state-of-the-art computer model of the atmosphere that incorporates scores of physical and chemical environmental processes. The new findings, to be published in Geophysical Research Letters, come to light just after the Environmental Protection Agency's recent ruling against states setting specific emission standards for this greenhouse gas based in part on the lack of data showing the link between carbon dioxide emissions and their health effects. ...> Full Article Lung Cancer Cells' Survival Gene Seen as Drug Target (1/4/2008)One of the deadliest forms of cancer appears to carry a specific weakness. When a key gene called 14-3-3zeta is silenced, lung cancer cells can't survive on their own, researchers have found. ...> Full Article Researchers Show that Fibrosis can be Stopped, Cured and Reversed Modified Protein May Lead to First Cure for Cirrhosis of the Liver (1/3/2008)Researchers have proven in animal studies that fibrosis in the liver can be not only stopped, but reversed. Their discovery, to be published in PLoS Online on December 26, opens the door to treating and curing conditions that lead to excessive tissue scarring such as viral hepatitis, fatty liver disease, cirrhosis, pulmonary fibrosis, scleroderma and burns. ...> Full Article Gene variation may elevate risk of liver tumor in patients with cirrhosis (1/3/2008)Growth factor pathway may be target for preventive treatment ...> Full Article Cancer Cell Line Developed That Is Resistant To New Cancer Therapy (1/3/2008)A cancer cell line that is resistant to one of the newest classes of cancer treatments has been developed by researchers who already are using it to determine what else to give patients when this happens. ...> Full Article Potential Drug Target For Treatment-resistant Prostate Cancer Discovered (1/2/2008)Scientists at Jefferson's Kimmel Cancer Center in Philadelphia have found that a signaling protein that is key to prostate cancer cell growth is turned on in nearly all recurrent prostate cancers that are resistant to hormone therapy. If the findings hold up, the protein, called Stat5, may be a specific drug target against an extremely difficult-to-treat cancer. ...> Full Article Research Suggests New Treatment Suitable for All Patients With Least-Curable Brain Tumors (1/2/2008)New research at Wake Forest University Baptist Medical Center suggests that a three-drug cocktail may one day improve outcomes in patients with glioblastoma multiforme (GBM), a type of brain tumor with a dismal prognosis. Two of the drug candidates have been developed, and the team is working on the third - all targeted to kill or impair cancer cells and spare healthy brain. ...> Full Article Restless Legs Syndrome Doubles Risk of Stroke and Heart Disease (1/2/2008)People with restless legs syndrome (RLS) are twice as likely to have a stroke or heart disease compared to people without RLS, and the risk is greatest in those with the most frequent and severe symptoms, according to research published in the January 1, 2008, issue of Neurology®, the medical journal of the American Academy of Neurology. ...> Full Article Overeating And Obesity Triggered By Lack Of One Gene (1/1/2008)According to the Centers for Disease Control and Prevention, close to one-third of the population in the United States is obese and another third is overweight. Excessive weight gain is elicited by alterations in energy balance, the finely modulated equilibrium between caloric intake and expenditure. But what are the factors that determine how much food is consumed? ...> Full Article Scientists Discover New Role For MiRNA In Leukemia (1/1/2008)Scientists here have found that mini-molecules called micro-RNA may play a critical role in the progression of chronic myeloid leukemia (CML) from its more treatable chronic phase to a life-threatening phase, called blast crisis. ...> Full Article Breast Cancer Cells Have To Learn To Walk Before They Can Run (1/1/2008)Early-stage breast cancer that has not yet invaded the surrounding tissues may already contain highly motile cells, bringing the tumor one step closer to metastasis, report researchers at the Salk Institute for Biological Studies. ...> Full Article |
