Two studies by researchers at UT Southwestern Medical Center could lead to new treatments for lupus and other autoimmune diseases and strengthen current therapies for viral, bacterial, and parasitic infections. http://medicalxpress.com/news/2013-02-enzyme-innate-immunity-sensor.html Medical research Fri, 15 Feb 2013 10:58:09 EST news280148279 (Medical Xpress)—As obesity rates continue to rise, experts are searching for answers in the clinic and at the lab bench to determine the types and amounts of food that people should eat. http://medicalxpress.com/news/2013-02-worm-clues-obesity.html Medical research Fri, 08 Feb 2013 06:35:08 EST news279527698 (Medical Xpress)—In a new study, University at Buffalo scientists describe the role that a protein called TFIIB plays in helping cells repair DNA damage, a critical function for preventing the growth of tumors. http://medicalxpress.com/news/2012-11-protein-role-cells-dna.html Medical research Thu, 01 Nov 2012 13:46:34 EST news270996381 A team of neuroscientists and informatics experts at Cold Spring Harbor Laboratory (CSHL) reports important progress in an effort to understand the relationship between transposons – sequences of DNA that can jump around within the genome, potentially causing great damage – and mechanisms involved in serious neurodegenerative disorders including ALS (amyotrophic lateral sclerosis, also known as Lou Gehrig's disease), FTLD (frontotemporal lobar degeneration) and Alzheimer's disease. http://medicalxpress.com/news/2012-09-storm-awakened-transposons-brain-cell-pathologies.html Genetics Thu, 06 Sep 2012 11:51:24 EST news266151077 BGI, the world's largest genomics organization, developed single-cell genome sequencing technology and published two research papers for cancer single-cell sequencing in the research journal Cell. In the papers, which were published today in the same issue of Cell, BGI researchers applied their new single-cell sequencing (SCS) method to identify the genetic characteristics of essential thrombocythemia (ET, a kind of blood neoplasm) and clear cell renal cell carcinoma (ccRCC, a typical kidney cancer), and demonstrated that single cell analyses of highly heterogeneous tissues provide much clearer intratumoral genetic pictures and developmental history than previous bulk tissue sequencing. http://medicalxpress.com/news/2012-03-single-cell-sequencing-era-cancer.html Genetics Fri, 02 Mar 2012 10:47:05 EST news249907619 UCSF scientists have discovered the unexpected way in which a key cell of the immune system prepares for battle. The finding, they said, offers insight into the processes that take place within these cells and could lead to strategies for treating conditions from spinal cord injury to cancer. http://medicalxpress.com/news/2012-01-immune-cells-invaders.html Immunology Thu, 19 Jan 2012 15:52:17 EST news246210722
