(Medical Xpress)—Cell biologists studying Parkinson's disease are training their sights on mitochondria, the energy source of the cell, whose activity in neurons appears to go awry in this devastating neurodegenerative illness. A neuron needs its mitochondria to be healthy and mobile, particularly during their continual cycles of fission and fusion in which damaged bits are removed and healthy mitochondria are renewed. http://medicalxpress.com/news/2013-03-gene-mutated-parkinson-disease-function.html Medical research Fri, 22 Mar 2013 10:00:05 EST news283163411 The number of incorrect cancer prognoses can be halved with computerised image analysis. In three years time, the method can be used on patients with bowel cancer, ovarian cancer and prostate cancer. http://medicalxpress.com/news/2013-02-method-halves-wrongful-cancer-prognoses.html Cancer Wed, 06 Feb 2013 08:12:39 EST news279360748 Researchers at Hospital for Special Surgery have identified a potential new target for drugs to treat patients with rheumatoid arthritis (RA), a protein known as IRHOM2. The finding could provide an effective and potentially less toxic alternative therapy to tumor necrosis factor-alpha blockers (TNF-blockers), the mainstay of treatment for rheumatoid arthritis, and could help patients who do not respond to this treatment. Efforts to develop drugs that hone in on this new target are underway. http://medicalxpress.com/news/2013-01-rheumatoid-arthritis.html Arthritis & Rheumatism Fri, 25 Jan 2013 12:00:04 EST news278334739 Human corneal endothelial cells (HCEnCs) form a monolayer of hexagonal cells whose main function is to maintain corneal clarity by regulating corneal hydration. Cell loss due to aging or corneal endothelial disorders, such as Fuchs dystrophy, can lead to cornea edema and blindness, resulting in the need for cornea transplants. http://medicalxpress.com/news/2012-12-cornea-endothelial-cell-lines-powerful.html Ophthalmology Thu, 27 Dec 2012 13:03:43 EST news275835810 Cholesterol plays a key role in regulating proteins involved in cell signaling and may be important to many other cell processes, an international team of researchers has found. http://medicalxpress.com/news/2012-12-cholesterol-key-proteins-cell.html Medical research Wed, 19 Dec 2012 12:04:56 EST news275141089 An embryo is an amazing thing. From just one initial cell, an entire living, breathing body emerges, full of working cells and organs. It comes as no surprise that embryonic development is a very carefully orchestrated process—everything has to fall into the right place at the right time. Developmental and cell biologists study this very thing, unraveling the molecular cues that determine how we become human. http://medicalxpress.com/news/2012-12-junk-dna-embryonic.html Genetics Mon, 03 Dec 2012 10:28:43 EST news273752889 (Medical Xpress)—New insights into a protein complex that regulates the very tips of chromosomes could improve methods of screening anti-cancer drugs. http://medicalxpress.com/news/2012-11-proteins-dna-cancer-insight.html Medical research Thu, 29 Nov 2012 15:46:00 EST news273426351 (Medical Xpress)—Scientists at the University of Bath are one step further to understanding the role of one of the proteins that causes the neurodegenerative disorder, Amyotrophic Lateral Sclerosis (ALS), also known as Motor Neurone Disease (MND). http://medicalxpress.com/news/2012-10-clues-motor-neurone-disease.html Medical research Wed, 10 Oct 2012 07:48:36 EST news269074109 (Medical Xpress)—UC Davis investigators have found new evidence that a promising type of stem cell now being considered for a variety of disease therapies is very similar to the type of cells that give rise to cancer. The findings suggest that although the cells—known as induced pluripotent stem cells (iPSCs)—show substantial promise as a source of replacement cells and tissues to treat injuries, disease and chronic conditions, scientists and physicians must move cautiously with any clinical use because iPSCs could also cause malignant cancer. http://medicalxpress.com/news/2012-09-multiple-similarities-cancer-cells-pluripotent.html Medical research Fri, 28 Sep 2012 13:49:33 EST news268058965 An international research team led by cell biologists at the University of California, Riverside has uncovered a new insight into colon cancer, the third leading cause of cancer-related deaths in the United States. The research provides potential new avenues for diagnosing and treating the disease. http://medicalxpress.com/news/2012-02-cell-biologists-mechanism-people-susceptible.html Cancer Thu, 09 Feb 2012 17:29:07 EST news248030925
