BU researchers identify mutational signatures and tumor activity in Chinese patients
Boston University School of MedicinePeer-Reviewed Publication
Many different mutational signatures, or "fingerprints" of DNA damage have been identified across different tumor types which can provide a record of environmental exposure or clues about the etiology of carcinogenesis. Most of the mutational signature characterization has been performed using tumors from American and European populations due to the availability of sequencing data in these regions from large-scale atlases such as The Cancer Genome Atlas and the International Cancer Genome Consortium. While some unique mutational signatures have been identified in various Asian populations, mutational signatures and their activity in tumors from Chinese patients have not been well characterized across cancer types.
Researchers from Boston University Chobanian & Avedisian School of Medicine have now identified mutational signatures that are highly active in a large Chinese population. They found that the majority of the mutation-causing processes were similar between American and Chinese populations. However, they did find differences in what the mutational signature activities were correlated with- Journal
