When cells suffer too much DNA damage, they are usually forced to undergo programmed cell death, or apoptosis. However, cancer cells often ignore these signals, flourishing even after chemotherapy drugs have ravaged their DNA. http://medicalxpress.com/news/2013-05-ids-key-protein-cell-death.html Genetics Tue, 14 May 2013 06:27:15 EST news287731615 Scientists at the University of Liverpool are working to identify genes involved in the development of bacterial meningitis to support the search for new vaccine candidates. http://medicalxpress.com/news/2013-04-analysing-meningitis-genes-treatments.html Diseases, Conditions, Syndromes Fri, 19 Apr 2013 07:56:02 EST news285576955 Researchers at the University of California, San Diego School of Medicine say overexpression of a protein called alpha-synuclein appears to disrupt vital recycling processes in neurons, starting with the terminal extensions of neurons and working its way back to the cells' center, with the potential consequence of progressive degeneration and eventual cell death. http://medicalxpress.com/news/2013-02-excess-protein-linked-parkinson-disease.html Parkinson's & Movement disorders Thu, 07 Feb 2013 14:52:55 EST news279471152 Researchers using sophisticated genetic testing techniques have identified a promising new biomarker for diagnosis of glioma—the most common type of malignant brain tumor, reports the January issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. http://medicalxpress.com/news/2013-01-biomarker-gliomas.html Cancer Wed, 16 Jan 2013 13:01:20 EST news277563674 A study led by researchers at the UC San Diego Stem Cell Research program and funded by the California Institute for Regenerative Medicine (CIRM) looks at an important RNA binding protein called LIN28, which is implicated in pluripotency and reprogramming as well as in cancer and other diseases. According to the researchers, their study – published in the September 6 online issue of Molecular Cell – will change how scientists view this protein and its impact on human disease. http://medicalxpress.com/news/2012-09-sites-lin28-protein-thousands-human.html Genetics Tue, 04 Sep 2012 12:00:01 EST news265962584 Imagine eating all of the sugar and fat that you want without gaining a pound. Thanks to new research published in The FASEB Journal, the day may come when this is not too far from reality. That's because researchers from the United States and Europe have found that blocking one of three opioid receptors in your body could turn your penchant for sweets and fried treats into a weight loss strategy that actually works. By blocking the delta opioid receptor, or DOR, mice reduced their body weight despite being fed a diet high in fat and sugar. The scientists believe that the deletion of the DOR gene in mice stimulated the expression of other genes in brown adipose tissue that promoted thermogenesis. http://medicalxpress.com/news/2012-07-opioid-receptors-drug-obesity.html Overweight and Obesity Tue, 31 Jul 2012 10:50:33 EST news262950619 Researchers have identified a potential new pathway in prostate cancer cells by which cancer-driving gene products can be generated, according to a study published in Cancer Discovery, a journal of the American Association for Cancer Research. http://medicalxpress.com/news/2012-06-abnormal-gene-product-prostate-cancer.html Cancer Tue, 19 Jun 2012 10:51:59 EST news259321786
