Liver hepatocarcinoma is a highly vascularized cancer, and more and more research is focused on the molecules controlling angiogenesis. In 2001, two novel peptides, known as prokineticin 1/EG-VEGF (PK1/EG-VEGF) and prokineticin 2/Bv8 (PK2/Bv8), were identified, as having potent angiogenic activities.

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.
