A study led by the Hospital del Mar Research Institute, with Cima University of Navarra and Pompeu Fabra University, has identified a group of small molecules exclusive to liver tumors that could be key to developing cancer vaccines. These are microproteins, very small proteins expressed only by tumor cells. This can result in the activation of immune cells against the tumor. The study is published in Science Advances. By integrating data from tumors and healthy tissue from over one hundred liver cancer patients, the researchers identified this set of microproteins. Read More
