Identifying 1,907 mitochondrial somatic mutations from 1,675 tumor tissues provides new insights into the causes and effects of the mitochondrial genome mutations found in human cancers.
Epigenome and Mitochondrial Barcode of Lineage from Endogenous Mutations (EMBLEM) enable tracking cell lineage in combination with chromatin profile in ATAC-seq data.
Many tumors are depleted of mitochondrial DNA; this depletion is associated with changes in gene expression and with the incidence of critical somatic mutations and alterations.
Yeast promoters can harbor multiple natural DNA variants that influence gene expression, interact genetically, evolve under negative selection, alter transcription factor motifs, and remain challenging to predict.
Transposable elements are not reactivated in natural hybrids of the yeast Saccharomyces paradoxus, but their accumulation is genotype-specific and is not predicted by the evolutionary divergence between a hybrid's parents.
