Researchers at the University of Pennsylvania School of medicine have discovered that a protein called FOXA2 controls genes that maintain the proper level of bile in the liver. FOXA2 may become the focus for new therapies to treat diseases that involve the regulation of bile salts. The study was published online this week in Nature medicine.read more

The research paper, published with colleagues from Colorado State University and the University of South Carolina, appeared in the early online edition of the Proceedings of the National Academy of Science.

Two new studies examine the use of the nucleoside polymerase inhibitor, R1626, to the standard therapy for hepatitis C. The reports appear in the August issue of Hepatology, a journal published by John Wiley & Sons on behalf of the American Association for the study of Liver Diseases (AASLD). The articles are available online at Wiley Interscience (http://www.interscience.wiley.com/).

The decision to undergo surgery can be particularly difficult and confusing for older adults. In a study published in the July 2008 issue of the Journal of Bone and Joint Surgery, Richard M. Frankel, Ph.D., of the Indiana University School of medicine, and colleagues report that older patients and their surgeons do not communicate effectively when exploring surgical treatment options.

The drug warfarin may help prevent liver failure in thousands of people with Hepatitis C, according to new research. In a study published in the Journal of Thrombosis and Haemostasis, researchers show that warfarin reduces the scarring on the liver caused by Hepatitis C. This scarring, or fibrosis, replaces normal liver cells and can lead to cirrhosis of the liver and ultimately liver failure.

According to a study published on bmj.com, most cancer patients make a decision about treatment with little or no information about the survival benefits of palliative chemotherapy. Palliative chemotherapy is a way to reduce the severity of symptoms for patients with advanced cancer.
