A new study of genetically modified immune cells by scientists from UCLA and the California Institute of Technology could help improve a promising treatment for melanoma, an often fatal form of skin cancer. http://medicalxpress.com/news/2013-03-immune-cell-therapy-melanoma-treatment.html Cancer Fri, 22 Mar 2013 09:40:05 EST news283163228 (Medical Xpress)—A little more than a year after the FDA approved Kalydeco (Vx-770), the first drug of its kind to treat the underlying cause of cystic fibrosis, University of Missouri researchers believe they have found exactly how this drug works and how to improve its effectiveness in the future. Described in the current issue of the Proceedings of the National Academy of Sciences, MU researchers have redefined a key regulatory process in the defective protein responsible for cystic fibrosis that could change the way scientists approach the lethal genetic disease. http://medicalxpress.com/news/2013-03-discovery-efficacy-cystic-fibrosis-drug.html Medical research Thu, 21 Mar 2013 14:21:27 EST news283094460 The bacteria that cause acne live on everyone's skin, yet one in five people is lucky enough to develop only an occasional pimple over a lifetime.

These are the findings of a study conducted by Leiden PhD candidate Yves Aubert and colleagues at the division of Medical Pharmacology of the Leiden Academic Center for Drug Research (LACDR & LUMC). http://medicalxpress.com/news/2012-12-sexual-social-behaviour-serotonin-drugs.html Medications Wed, 12 Dec 2012 08:13:19 EST news274522382 Liposarcoma, the most common type of sarcoma, is an often lethal form of cancer that develops in fat cells. It is particularly deadly, in part, because the tumors are not consistently visible with positron emission tomography (PET) scans that use a common probe called FDG and because they frequently do not respond to chemotherapy. http://medicalxpress.com/news/2012-12-scientists-liposarcoma-tumors-chemotherapy.html Cancer Mon, 10 Dec 2012 13:34:43 EST news274368875 Each year, about 610,000 Americans suffer their first heart attack, according to the Centers for Disease Control and Prevention. Heart attacks and other symptoms of cardiovascular disease can be caused when blockage occurs in the arteries. In a new study from the University of Missouri, a scientist has discovered a natural defense against arterial blockage: bilirubin. http://medicalxpress.com/news/2012-12-bilirubin-cardiovascular-disease.html Cardiology Thu, 06 Dec 2012 10:41:42 EST news274012887 Compared to normal cells, cancer cells have a prodigious appetite for glucose, the result of a shift in cell metabolism known as aerobic glycolysis or the "Warburg effect." Researchers focusing on this effect as a possible target for cancer therapies have examined how biochemical signals present in cancer cells regulate the altered metabolic state. http://medicalxpress.com/news/2012-06-glucose-deprivation-feedback-loop-cancer.html Cancer Tue, 26 Jun 2012 14:08:55 EST news259938526 A second mutation found in the tumors of patients with BRAF-mutated metastatic melanoma does not contribute to resistance to BRAF inhibitor drugs, a finding that runs counter to what scientists expected to be true. http://medicalxpress.com/news/2012-04-mutation-braf-mutated-melanoma-doesnt-contribute.html Cancer Sun, 01 Apr 2012 14:39:18 EST news252509939 Cancer is tough to kill and has many ways of evading the drugs used by oncologists to try and eliminate it. http://medicalxpress.com/news/2012-03-scientists-uncover-mechanism-melanoma-drug.html Cancer Tue, 06 Mar 2012 11:16:51 EST news250254999
