Researchers from the University of Michigan Comprehensive Cancer Center have identified a specific molecule that alters how breast cancer cells move. This affects the cells' ability to spread or metastasize to distant parts of the body, the hallmark of deadly, aggressive cancer. http://medicalxpress.com/news/2011-10-cell-movement-clues-aggressive-breast.html Cancer Mon, 03 Oct 2011 11:47:08 EST news236861210 Research at Loyola University Chicago Stritch School of Medicine could help lead to new ways to prevent coronary arteries from reclogging after balloon angioplasties. http://medicalxpress.com/news/2011-09-approach-arteries-balloon-angioplasties.html Cardiology Fri, 30 Sep 2011 07:31:23 EST news236586673 Researchers have shown they can reverse the aging process for human adult stem cells, which are responsible for helping old or damaged tissues regenerate. The findings could lead to medical treatments that may repair a host of ailments that occur because of tissue damage as people age. A research group led by the Buck Institute for Research on Aging and the Georgia Institute of Technology conducted the study in cell culture, which appears in the September 1, 2011 edition of the journal Cell Cycle. http://medicalxpress.com/news/2011-09-scientists-clock-adult-stem-cells.html Medical research Tue, 20 Sep 2011 15:46:00 EST news235752345 Could engineered fatty particles help prevent AIDS?

This achievement, made by researchers of the Colorectal Cancer Lab at the Institute for Research in Biomedicine (IRB Barcelona) and published in Nature Medicine, is a crucial advance towards regenerative medicine. http://medicalxpress.com/news/2011-09-scientists-human-intestinal-stem-cell.html Medical research Sun, 04 Sep 2011 13:02:08 EST news234359931 Researchers have found that a protein variation linked by some genetic studies to Alzheimer's disease is consistently present in the brains of people with Alzheimer's. In further biochemical and cell culture investigations, they have shown that this protein, known as ubiquilin-1, performs a critical Alzheimer's-related function: it "chaperones" the formation of amyloid precursor protein, a molecule whose malformation has been directly tied to Alzheimer's pathology. http://medicalxpress.com/news/2011-09-alzheimer-brains-key-protein.html Medical research Thu, 01 Sep 2011 11:23:43 EST news234094982 Collaborating researchers at Stanford University and The Scripps Research Institute have identified chemical compounds that show promise as potential therapeutics for a set of medical conditions caused by the abnormal clumping together of a protein known as transthyretin (TTR). http://medicalxpress.com/news/2011-08-scientists-drug-candidates-protein-folding-diseases.html Medical research Mon, 29 Aug 2011 14:45:04 EST news233847868 Researchers at the University of Toronto, The Hospital for Sick Children (SickKids), St. Paul's Hospital and the University of British Columbia have identified a new treatment target for a virus that causes severe lung infections and an estimated 10% of common colds. http://medicalxpress.com/news/2011-08-pathway-infection-common-potentially-life-threatening.html Medical research Mon, 15 Aug 2011 11:08:34 EST news232625297 Mensenchymal stem cells (MSCs), multipotent cells identified in bone marrow and other tissues, have been shown to be therapeutically effective in the immunosuppression of T-cells, the regeneration of blood vessels, assisting in skin wound healing, and suppressing chronic airway inflammation in some asthma cases. Typically, when MSCs are being prepared for therapeutic applications, they are cultured in fetal bovine serum. http://medicalxpress.com/news/2011-06-serum-free-cultures-transplanted-mscs-efficacy.html Medical research Tue, 28 Jun 2011 12:01:05 EST news228481252 A team led by Joan Brugge, the Louise Foote Pfeiffer Professor of Cell Biology at Harvard Medical School, recently shed light on how ovarian cancer spreads. In a paper published in the July edition of the journal Cancer Discovery, the newest journal of the American Association for Cancer Research, Brugge and colleagues found that ovarian cancer cells act like bullies, using brute force to plow their way through tissue and colonize additional organs. http://medicalxpress.com/news/2011-06-scientists-image-stages-ovarian-cancer.html Cancer Tue, 14 Jun 2011 13:38:29 EST news227277494 A mutant gene long thought to accelerate tumor growth in thyroid cancer patients actually inhibits the spread of malignant cells, showing promise for novel cancer therapies, a Mayo Clinic study has found. http://medicalxpress.com/news/2011-06-cancer-mayo-clinic-thyroid-gene.html Cancer Sat, 04 Jun 2011 13:45:36 EST news226413912 German researchers have identified an unexpected molecular marker that predicts how sensitive hard-to-treat triple-negative breast cancers are to chemotherapy. http://medicalxpress.com/news/2011-05-gene-chemotherapy-sensitivity-triple-negative-breast.html Cancer Thu, 05 May 2011 10:05:37 EST news223808703
