Although the study was small, the investigators believe it provides proof of principle for the usefulness of cell-free DNA to prognose and monitor glioblastomas.
In PNAS this week: transcriptomic and epigenomic sequence differences in glioblastoma models, approach to analyze small amounts of extracellular RNA, and more.
Molecular features in primary and recurrent glioblastomas indicated that key initiator mutations turned up years before diagnosis, often persisting in recurrent tumors.
Using RNA sequence data from the Cancer Genome Atlas and the Chinese Glioma Genome Atlas, researchers identified six genes with expression ties to overall survival.
In Genome Biology this week: post-transcriptional modification-based stratification of glioblastoma, single-cell analysis of gene expression and methylation in human iPSCs, and more.
