Exome sequencing and other molecular strategies led to a heterogeneous variant in the DNMT3A gene that appears to impact host epigenetic and immune features.
With DNA methylation data for more than 1,800 chronic lymphocytic leukemia B cells, researchers tracked CLL epimutation rates and saw lineages with distinct treatment responses.
Following promising data from its Circulating Cell-free Genome Atlas study, the firm decided to pivot its breast cancer trial to support its multi-cancer test.
Using archived tumor samples from individuals with glioblastoma, researchers saw methylation variability at progression, along with potential prognostic hints.
The team demonstrated that the approach can yield high sensitivity while maintaining near-perfect specificity, but it must now replicate the early results in a much larger study.
By studying koalas and a retrovirus that infects them, researchers may have uncovered a new sort of 'immune response' that occurs at the genomic level, Agence France Presse reports.
In Science this week: ancient genomes reveal social inequality within individual households, new method for quantifying genetic variation in gene dosage, and more.
