An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in Nature that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled in Switzerland. Hepatocellular carcinoma is usually diagnosed at a very late stage when the liver is already severely damaged and hence overall prognosis is poor. Detection of the anti-cancer protein LHPP as a biomarker may allow clinicians to provide better treatment options.
New anti-cancer protein LHPP
Liver tumors develop from mutated cells that grow and proliferate uncontrollably. Anti-cancer proteins, so-called tumor suppressors, prevent uncontrolled cell growth. Tumor suppressors are often defective in cancer cells. The researchers led by Prof. Michael N. Hall, Biozentrum of the University of Basel, have now discovered a new, so far unknown tumor suppressor, the protein LHPP. In their study, they show that the loss of LHPP promotes tumor growth and reduces
