Hanssen et al. show that CTCF–cohesin binding sites at the α-globin gene cluster function as boundaries to restrict the interaction of enhancers with the flanking chromatin, thus preventing abnormal gene expression.
Zhou et al. demonstrate that bone marrow adipocytes, but not intraperitoneal adipocytes, express high levels of stem cell factor (SCF), which is essential for the regeneration of haematopoietic stem cells and haematopoiesis after irradiation.
Pitulescu et al. and Hasan et al. show that Dll4–Notch signalling in endothelial tip cells regulates angiogenesis through control of artery formation, linking sprouting angiogenesis and artery formation.
Lengefeld et al. reveal how yeast cells distinguish between newly synthesized and pre-existing spindle pole bodies to enable their asymmetric segregation, through a mechanism involving Swe1, Kin3 and NuA4.
Pitulescu et al. and Hasan et al. show that Dll4–Notch signalling in endothelial tip cells regulates angiogenesis through control of artery formation, linking sprouting angiogenesis and artery formation.
Zhou et al. show that in the context of AML1-ETO-driven leukaemia, AES and DDX21 induce small nucleolar RNA (snoRNA)–ribonucleoprotein (RNP) formation and this is important for self-renewal of leukaemic cells.
Wang et al. show that glucose deprivation causes AMPK-dependent phosphorylation of fumarase leading to ATF2 binding and gene transcription for cell cycle arrest. In cancer cells O-GlcNAcylation of fumarase blocks ATF2 binding to allow proliferation.
Graf et al. demonstrate that Pramel7 maintains ground-state pluripotency by repressing DNA methylation through proteasomal degradation of UHRF1, thus linking the proteasome and epigenetics with cell fate regulation.
Wang et al. show that lipid-induced ROS lead to ACAT2 stabilization by oxidizing a cysteine residue, thereby preventing its ubiquitylation and ACAT2 degradation. They further show that ACAT2 stabilization improves lipotoxicity and insulin resistance.
Mierzwa et al. show that ESCRT-III subunit turnover at the cell midbody is driven by Vps4. Rapid turnover sustains the net growth of ESCRT-III assemblies in the presence of inhibitory Vps2 and Vps24 subunits.
Leushacke et al. provide insights into the role of Lgr5 cells in the oxyntic stomach, demonstrating that they label a subpopulation of chief cells that function as reserve stem cells during regeneration and cells-of-origin of gastric cancer.
Sinclair et al. show in Caenorhabditis elegans that intestinal HRG-7 communicates haem status with extra-intestinal tissues. Reciprocally, a DBL-1-dependent signal from neurons regulates both hrg-7 and haem transport.
Yuan et al. show that the MBNL3 splicing factor promotes alternative splicing of the lncRNA-PXN-AS1 antisense transcript of PXN, leading to the stabilization of PXN mRNA and increasing its protein levels to promote liver cancer growth.
Hoeck et al. show that disruption of the hair follicle stem cell compartment by loss of Lgr5+ stem cells is followed by an inflammatory response and CD34+ stem cell activation and proliferation, to eventually replenish the Lgr5+ population.
Cortical tension is thought to be generated by myosin II, and little is known about the role of actin network properties. Chugh et al. demonstrate that actin cortex thickness, determined by actin filament length, influences cortical tension.
Celià-Terrassa et al. find that by repressing LCOR, a modulator of the interferon response, miR-199a allows both normal and cancer mammary stem cells to evade senescence and differentiation, thus promoting tumorigenesis.
Two studies by Sugden et al. and Jin et al. show that endoglin regulates endothelial cell migration through VEGFR2 signalling and controls blood vessel diameter in response to blood flow.

Two papers by Liu et al. and Ansó et al. study the post-transcriptional regulation of mitochondrial factors in erythropoiesis and the role of RISP-mediated mitochondrial respiration in fetal and adult HSC function via metabolites and epigenetic changes.
