High Levels of Protein p62 Predict Liver Cancer

Study in mice and human tissues suggest new prognostic and therapeutic approach

Researchers from Dr. Michael Karin's laboratory (Project 1) have discovered that high levels of the protein p62 in human liver samples are strongly associated with cancer recurrence and reduced patient survival. In mice, they also found that p62 is required for liver cancer to form. 

Dr. Michael Karin said that “by defining factors that allow liver cells to progress from pre-cancer to cancer, we were able to find one — p62 — that we can also use to predict a liver cancer patient’s outcome following full removal of a previous liver tumor".
