    Metabolism feeds into gene regulation, allowing adaptation of gene expression to satisfy cellular needs, including in pathological scenarios such as cancer. Metabolism modulates gene expression through metabolites, which serve as cofactors for DNA and histone modifiers, and through metabolic enzymes, which locally regulate chromatin and transcription in the nucleus.

    Decline in stem cell function causes loss of tissue homeostasis and increased incidence of age-related diseases. During ageing, adult stem cells accumulate damage and the niche in which they reside malfunctions. These defects are associated with changes in the epigenome that contribute to organ dysfunction and disease.

    Taking advantage of genetic engineering, synthetic biology allows control and design of new cell functions. Recent advances in the development of genetic tools and the assembly of progressively more sophisticated gene circuits have made ‘designer cells’ a reality, with applications ranging from industry and biotechnology to medicine.

    The tumour suppressor PTEN regulates various cellular processes, including maintenance of genomic stability, cell survival, migration, proliferation and metabolism. Recent studies into the regulation of PTEN levels and activity provide new insights into its anti-oncogenic functions and offer novel opportunities for cancer treatment.

    DNA methylation in plants mediates gene expression, transposon silencing, chromosome interactions and genome stability. It is therefore not surprising that the regulation of DNA methylation is important for plant development and for plant responses to biotic and abiotic stresses.

    Ribosomes encounter obstacles during translation elongation that cause their stalling and can have a profound impact on protein yield. Ribosome stalling depends on the genetic code, amino acid availability, regulatory elements and mRNA context and can be resolved by resumption of translation or by ribosome rescue and recycling.

    Increased shortening of RNA 3′ untranslated regions associated with tumorigenic transformation interferes with competing endogenous RNA (ceRNA) networks, which results in trans-repression of tumour suppressors through microRNA-mediated silencing.

    Biomolecules can phase separate and form condensates that have roles in diverse cellular processes and contexts. Michnick and Bergeron-Sandoval comment on this rapidly progressing field and envisage that the study of biological phase separation will bring new understanding of cell and developmental biology.

    The spindle checkpoint complex BUB3–BUB1 facilitates telomere replication through recruitment of the helicase BLM, and the telomere capping protein TRF2 promotes replication at pericentromeres by recruiting the helicase RTEL1; both helicases resolve G-quadruplex structures.

    Cellular organelles extensively communicate with each other by close interactions, known as membrane contact sites. Schuldiner and Bohnert comment on the progress of this rapidly developing field, highlighting that the complexity of interactions at membrane contact sites is only now starting to emerge.
