The protein can regulate many cell activities and has a highly specific expression. Gaining an understanding about the expression of CLP in oral epithelial cells and its possible downregulation (or lack of production) in cancer may be a potentially valuable marker in early detection of oral cancer. A new study in the Journal of Prosthodontics found that CLP is expressed in normal human oral muscosal cells and that downregulation of this protein may be an indicator of malignancy or cancer. http://www.physorg.com/news150557236.html Medicine & Health Wed, 07 Jan 2009 13:27:16 EST news150557236 is no cure for spinal muscular atrophy (SMA), a genetic disorder that causes the weakening of muscles and is the leading genetic cause of infant death, but University of Missouri researchers have discovered a new therapeutic target that improves deteriorating skeletal muscle tissue caused by SMA.

Unfortunately, metastatic cancer cells have the relocation process down pat. Tripping nimbly from one abode to another, these migrating cancer cells often prove far more deadly than the original tumor. Although little has been known about how these rogue cells choose where to put down roots, researchers at the Stanford University School of Medicine have now learned just how nefarious they are. http://www.physorg.com/news150383375.html Medicine & Health Mon, 05 Jan 2009 13:09:35 EST news150383375 In a study to determine the diagnostic value of molecular imaging in nodal staging of patients with thyroid cancer, researchers were able for the first time to accurately distinguish between cancerous cells in regional lymph nodes and normal residual thyroid tissue directly after surgery. http://www.physorg.com/news150115125.html Medicine & Health Fri, 02 Jan 2009 10:38:45 EST news150115125 Liver biopsy is still considered the gold standard for grading, staging and "stad-ging" the chronic liver disease. In addition, it remains a primary source for acquiring new knowledge on the liver pathology. Demand for precise evaluations of the fibrosis and inflammatory tissue detectable in liver biopsy samples has been fuelled by the need to understand the closest-to-real effects of new antiviral molecules on the lesions characterising the histological patterns of chronic viral, toxic, metabolic and autoimmune diseases. http://www.physorg.com/news149924141.html Medicine & Health Wed, 31 Dec 2008 05:35:41 EST news149924141 Using stem cell lines not typically combined, researchers at Columbia University Medical Center have designed a new way to "grow" bone and other tissues. http://www.physorg.com/news148571674.html Medicine & Health Mon, 15 Dec 2008 13:54:34 EST news148571674
