Diet induces sex-divergent motif enrichment in liver. Top: Correlation analysis of ATAC-seq peaks in male and female mice fed a WD. Dashed lines indicate 1.2-fold change. Middle left: Strategy for analysis of motifs by group. Roman numerals represent the peak groups selected for motif analysis, which were subsequently used in Fig 3D and 3E. Bottom right: Heatmap showing the relative level of peaks selected from Fig 3B, separated by group.

Genome-coverage single-cell histone modifications for embryo lineage tracing | Nature
Substantial epigenetic resetting during early embryo development from fertilization to blastocyst formation ensures zygotic genome activation and leads to progressive cellular heterogeneities1–3. Mapping single-cell epigenomic profiles of core histone modifications that cover each individual cell is a fundamental goal in developmental biology. Here we develop target chromatin indexing and tagmentation (TACIT), a method that enabled genome-coverage single-cell profiling of seven histone modifications across mouse early embryos. We integrated these single-cell histone modifications with single-cell RNA sequencing data to chart a single-cell resolution epigenetic landscape. Multimodal chromatin-state annotations showed that the onset of zygotic genome activation at the early two-cell stage already primes heterogeneities in totipotency. We used machine learning to identify totipotency gene regulatory networks, including stage-specific transposable elements and putative transcription factor
