Following several years of study, investigators have found more evidence that viral therapy to treat solid tumors can be enhanced by blocking the body's natural immune response. http://medicalxpress.com/news/2013-03-evidence-blocking-immune-response-viral.html Cancer Wed, 13 Mar 2013 12:47:16 EST news282397623 When a research team from Denmark and Sweden compared the therapeutic capabilities of adipose-derived stem cells (ASCs) versus bone marrow-derived stem cells (BMSCs) obtained from a single 84 year-old male donor with ischemic coronary disease to regeneratively treat myocardial infarction in a rat model, they found that the ASCs preserved more cardiac function in the test rats while neither stem cell type induced myocardial angiogenesis (blood vessel growth.) http://medicalxpress.com/news/2013-02-stem-cell-source-important-factor.html Medical research Wed, 13 Feb 2013 17:01:59 EST news279997302 (HealthDay) -- Cells that normally form scar tissue after a heart attack can be reprogrammed into functional heart cells in mice, according to an experimental study published online April 18 in Nature. http://medicalxpress.com/news/2012-04-fibroblasts-reprogrammed-functioning-heart-cells.html Medical research Mon, 23 Apr 2012 06:40:02 EST news254374839 Researchers at Virginia Commonwealth University Medical Center's VCU Massey Cancer Center and Harold F. Young Neurosurgical Center (Richmond, VA) and Old Dominion University (Norfolk, VA) have discovered that suppression of Wilms tumor 1 protein (WT1) results in downregulation of CD97 gene expression in three glioblastoma cell lines and reduces the characteristic invasiveness exhibited by glial tumor cells. This finding is announced in the article, "Novel report of expression and function of CD97 in malignant gliomas: correlation with Wilms tumor 1 expression and glioma cell invasiveness," by Archana Chidambaram, Ph.D., and colleagues, published online ahead of print today in the Journal of Neurosurgery. Although further studies must be performed, the authors propose that CD97 may prove to be a new target for anti-glioma therapies. http://medicalxpress.com/news/2012-02-cd97-gene-function-wt1-protein.html Neuroscience Tue, 07 Feb 2012 10:30:01 EST news247832331 Scientists at the Walter and Eliza Hall Institute have discovered a key molecule needed to kill the blood vessels that supply tumours. http://medicalxpress.com/news/2011-06-strategy-tumor-feeding-blood-vessels.html Medical research Mon, 06 Jun 2011 10:02:20 EST news226573325
