Cancer Most searches for druggable tumor-specific antigens (TSAs) start with an examination of peptides derived from protein-coding exons. Laumont et al. took a different approach and found numerous TSAs that derived from aberrant expression of noncoding sequences in murine cell lines and in B-lineage acute lymphoblastic leukemia and lung cancer patient samples. They validated the immunogenicity and efficacy of TSA vaccination for select antigens in mouse models of cancer. Noncoding regions are a potentially rich source of TSAs that could greatly expand the number of targetable antigens across different cancers, including those with low mutational burdens. Sci. Transl.
