PITTBURGH, July 11, 2007 — Researchers from the University of Pittsburgh School of Medicine report a significant new advance in the search for an effective treatment for human liver cancer in the July issue of Molecular Cancer Therapeutics. Using a newly available monoclonal antibody, they demonstrated significant reductions in tumor cell proliferation and survival in human and mouse hepatocellular cancer (HCC) cell lines. According to the researchers, this finding has significant implications not only for the treatment of liver cancer but for a number of different types of cancer.
