Keklikoglou et al. report that cytotoxic drugs induce tumour-derived extracellular vesicles that facilitate monocyte expansion through annexin A6 and thus lung metastasis in breast cancer.
Giulitti et al. deliver modified mRNAs encoding OCT3/4, SOX2, KLF4 and cMYC as well as NANOG in microfluidics to directly convert human fibroblasts into naive induced pluripotent stem cells; the confined environment leads to enhanced efficiency and homogeneity compared to traditional methods.
Ancestral experience of mitochondrial stress is now found to render progeny of the roundworm Caenorhabditis elegans more resistant to the same insult for up to four generations. A DNA modification, N6-methyldeoxyadenine, is implicated in the inheritance of this stress adaptation.
Studying blastoderm spreading in zebrafish, Petridou et al. discover that this process is facilitated by tissue fluidization, mediated by a local loss of cell–cell adhesion during mitotic rounding and spatially restricted by Wnt.
Harada et al. develop a chromatin integration labelling (ChIL) method to map distributions of histone modifications and DNA-binding factors at low-input or even single-cell levels.
Ma et al. show that exposure of Caenorhabditis elegans to mitochondrial stress triggers stress adaptation in offspring, which is mediated by 6mA DNA modification at mitochondrial unfolded-protein-response genes.
RIPK1 plays a key role in several inflammatory and cell death signalling pathways. Understanding its regulation is pivotal for identifying diseases that might therapeutically benefit from RIPK1 inhibition. Recent studies now show that TBK1 and IKKε constitute a cell death checkpoint that restrains RIPK1 activation.
BAF is a heterogenous chromatin-remodelling complex, frequently mutated in cancer. A study now defines genome-wide localization patterns of three complexes, cBAF, PBAF and previously unknown ncBAF, and reveals the ncBAF complex as a specific vulnerability in synovial sarcoma and malignant rhabdoid tumours.
Scientists are increasingly embracing social media in their professional lives. Here, we look at the different platforms available to researchers and how social media engagement can positively influence their day-to-day work and scientific communication.
Lawson et al. review recent advances in single-cell technologies and discuss in detail how they can be leveraged to understand tumour heterogeneity and metastasis.
In this Review, Leidal et al. discuss the role and regulation of autophagy in aging. They cover how autophagy promotes longevity and restricts cellular damage, and discuss autophagy modulators for the potential treatment of age-related diseases.
Avgustinova et al. report that targeting the H3K9 methyltransferase G9a in skin cancer does not affect single nucleotide variant profiles, but leads to increased tumour aggressiveness after a prolonged latency.
During mitosis, the kinetochore connects chromosomes to spindle microtubules and enables chromosome segregation. A genetic study in vertebrate cells demonstrates phosphorylation-regulated plasticity of kinetochore assembly and highlights the role of the centromere protein T in load-bearing kinetochore–microtubule attachment.
Xin et al. track stem cells in live mice to show that fate determination is a flexible process during homeostatic hair follicle growth, and progenitor cells can change differentiation outcomes as a consequence of dynamic relocation.
Lafont et al. uncover a checkpoint mediated by TBK1 and IKKε, which phosphorylate RIPK1 in the TNFR1-SC. TBK1 and IKKε recruitment depends on M1 ubiquitylation and NEMO to restrict TNF-induced cell death.
Hara et al. find that the recruitment of the KMN kinetochore protein network is mainly dependent on the CENP-T pathway and promoted by Cdk1-mediated phosphorylation of CENP-T in chicken DT40 cells.
