Developing brain tumors can coax assistance from nearby cells known as microglia, according to a new study from scientists at Washington University School of Medicine in St. Louis. The researchers have identified one protein made by microglia that helps accelerate tumor growth and are looking for others.
The way the liver renews itself may be simpler than what scientists had been assuming. A new study, appearing in the April 13 issue of the Journal of Biological Chemistry, provides new information on the inner workings of cells from regenerating livers that could significantly affect the way physicians make livers regrow in patients with liver diseases such as cirrhosis, hepatitis or cancer.
The Hamilton Project, an initiative at the Brookings Institution, hosted a forum, “Health Care Reconsidered: Options for Change,” today at the Brookings Institution in Washington, D.C. At the event, policy papers on reforming Medicare Part “D” (including closing the “donut hole” gap in prescription drug coverage), improving preventive care and promoting greater affordability through progressive cost-sharing were released by The Hamilton Project.
Collaborators from Mayo Clinic and IBM have exploited parallel computer architecture and memory bandwidth to dramatically speed the processing of 3-D medical images.
Researchers at the Kimmel Cancer Center at Jefferson have identified a protein that they say is key to helping a quarter of all breast cancers spread. The finding, reported online the week of April 9, 2007 in the journal Proceedings of the National Academy of Sciences, could be a potential target for new drugs aimed at stopping or slowing the growth and progression of breast cancer.
Building on their 2005 discovery of an enzyme that is a natural tumor suppressor, researchers at the University of California, San Diego (UCSD) School of Medicine have now identified two variants of that enzyme which could provide new targets for therapies to treat diabetes, heart and neurological disease.
The proportion of Americans who are severely obese — about 100 pounds or more overweight — increased by 50 percent from 2000 to 2005, twice as fast as the growth seen in moderate obesity, according to a RAND Corp. study issued today.
An RNA-binding protein that is overproduced in ovarian cancer may present a new target for diagnosis or treatment of ovarian and other cancers, according to researchers at the University of Illinois at Chicago.
After a viral infection, a small percentage of the T cells generated to kill virus-infected cells remain on guard to establish long-term immunity. These so-called memory T cells, which derive from a family of immune cells known as CD8 T cells, engage in a self-renewal process that is essential to their persistence.
Innovative pulmonary and PEGylation-based therapeutic product development is the focus of two new business units recently created at Nektar Therapeutics (Nasdaq: NKTR), the company announced today.
