    • Metabologenomics integrates multi-omics data into genome-scale metabolic models (GEMs) to analyse complex metabolic networks. Mardinoglu and Palsson review advancements in GEMs at the global, cell- and tissue-specific, microbiome and whole-body levels, with insights into their applications towards improving health care.

      Review Article
    • Toxicogenomics leverages molecular data to predict toxicological effects. In this Review, the authors summarize innovations in transcriptomics and emerging methods, such as single-cell technologies and multi-omics, that offer detailed insights into toxicological mechanisms to enhance hazard prediction and risk assessment.

      Review Article
    • Mosaic variegated aneuploidy is a rare condition in which the copy number of different chromosomes varies across some cells within an individual. In this Review, the authors discuss the genetic underpinnings and clinical manifestations of this condition and relate these findings to the consequences of chromosomal instability more broadly.

      Review Article
    • In this Review, the authors provide an overview of the roles of individual histone variants in multiple processes, including gene regulation, DNA replication and DNA repair, and the cellular consequences of their dysfunction.

    Research Highlight
  • Yimiao Qu and Kyle Loh discuss a 2004 paper by Xie et al., who demonstrated that B cells can be reprogrammed into macrophages through the enforced expression of a single transcription factor, providing insights into cellular plasticity and lineage conversion.

    Comment
  • Merly C. Vogt recalls a seminal paper by Greer et al., who demonstrated the transgenerational inheritance of longevity, a complex trait, in Caenorhabditis elegans by manipulating the trimethylation of histone H3 lysine 4 (H3K4me3) in the parental generation.

Single-cell omics

Many biological phenomena are either invisible or only partially characterized when interrogated using standard analyses that average data across a bulk population of cells. Now, technological advances are providing unprecedented opportunities to analyse the complexities of biological systems at the single-cell level. High-throughput analyses of the genomes, transcriptomes and proteomes of single cells are yielding novel and important insights into diverse processes such as development, gene-expression dynamics, tissue heterogeneity and disease pathogenesis. In this Focus issue, we highlight the transformative potential of single-cell omics approaches.
