Genome-wide mapping and analysis of chromosome architecture
Nature Reviews Molecular Cell Biology 17, 743 (2016). doi:10.1038/nrm.2016.104 Authors: Anthony D. Schmitt, Ming Hu & Bing Ren Chromosomes of eukaryotes adopt highly dynamic and complex hierarchical structures in the nucleus. The three-dimensional (3D) organization of chromosomes profoundly affects DNA replication, transcription and the repair of DNA damage. Thus, a thorough understanding of nuclear architecture is fundamental to the study of nuclear processes (Source: Nature Reviews Molecular Cell Biology)

Cancer biology: Hypoxia as an off switch for gene expression
Nature Reviews Molecular Cell Biology 17, 610 (2016). doi:10.1038/nrm.2016.119 Author: Paulina Strzyz A new study shows that hypoxia interferes with DNA demethylation, resulting in DNA hypermethylation and repression of gene expression, which in tumours leads to the silencing of tumour suppressors.

Control of brown and beige fat development
Nature Reviews Molecular Cell Biology 17, 691 (2016). doi:10.1038/nrm.2016.96 Authors: Wenshan Wang & Patrick Seale Brown and beige adipocytes expend chemical energy to produce heat and are therefore important in regulating body temperature and body weight. Brown adipocytes develop in discrete and relatively homogenous depots of brown adipose tissue, whereas beige adipocytes are induced to develop in white adipose tissue (Source: Nature Reviews Molecular Cell Biology)

Slowing ageing by design: the rise of NAD+ and sirtuin-activating compounds
Nature Reviews Molecular Cell Biology 17, 679 (2016). doi:10.1038/nrm.2016.93 Authors: Michael S. Bonkowski & David A. Sinclair The sirtuins (SIRT1–7) are a family of nicotinamide adenine dinucleotide (NAD+)-dependent deacylases with remarkable abilities to prevent diseases and even reverse aspects of ageing. Mice engineered to express additional copies of SIRT1 or SIRT6, or treated with sirtuin-activating compounds (STACs) such as resveratrol (Source: Nature Reviews Molecular Cell Biology)

Coenzyme A: to make it or uptake it?
Nature Reviews Molecular Cell Biology 17, 605 (2016). doi:10.1038/nrm.2016.110 Authors: Ody C.M. Sibon & Erick Strauss The consensus has been that intracellular coenzyme A (CoA) is obtained exclusively by de novo biosynthesis via a universal, conserved five-step pathway in the cell cytosol. However, old and new evidence suggest that cells (and some microorganisms) have several strategies to obtain CoA, with (Source: Nature Reviews Molecular Cell Biology)

Notch signalling in context
Nature Reviews Molecular Cell Biology 17, 722 (2016). doi:10.1038/nrm.2016.94 Author: Sarah J. Bray The highly conserved Notch signalling pathway functions in many different developmental and homeostatic processes, which raises the question of how this pathway can achieve such diverse outcomes. With a direct route from the membrane to the nucleus, the Notch pathway has fewer opportunities for regulation (Source: Nature Reviews Molecular Cell Biology)
