    Depletion of homeostatic chemokines associated with microbial infection is also observed during non‐infectious and chronic inflammation, resulting in diminished lymphocyte trafficking.

    Synopsis

    Noncanonical NF‐κB signaling produces homeostatic chemokines, which direct naïve lymphocytes into secondary lymphoid organs (SLOs). TNF accumulation in inflamed SLOs alters this homeostasis by subverting noncanonical signaling.

    • LTβR‐stimulated noncanonical RelB NF‐κB signaling produces homeostatic chemokines in SLOs.

    • TNF abrogates LTβR‐stimulated noncanonical RelB activity.

    • TNF inhibits NIK and induces the production inhibitory p100‐IκBδ.

    • A TNF‐p100 pathway downregulates homeostatic chemokines in inflamed SLOs.

    Nutrient removal from cancer cells is counterbalanced through p53‐dependent induction of pro‐survival lncRNA TRINGS and suppression of cell death signalling.

    Synopsis

    A screen for pathways by which p53 can play protective roles in tumor cell survival identifies the long non‐coding (lnc) RNA TRINGS (Tp53‐regulated inhibitor of necrosis under glucose starvation) as pro‐survival factor in cancer cells under nutrient stress, shedding light on tumorigenic roles of p53.

    • The p53‐dependent lncRNA TRINGS is expressed in human cancer cells upon glucose starvation.

    • p53 binding to the TRINGS promoter and transcriptional activity are required for TRINGS expression.

    • TRINGS depletion causes stress‐induced necrotic cell death and decreased cancer cell growth in vitro and in vivo.

    • TRINGS physically interacts with scaffold protein STRAP, leading to its destabilisation through the ubiquitin‐proteasome system.

    • TRINGS‐promoted cell survival is mediated via STRAP‐GSK3β‐NF‐κB signalling.

    Tumor‐associated macrophages express the EMT‐associated transcription factor ZEB1, which drives their tumor‐promoting and chemotherapy‐resistance functions in mouse ovarian cancer models.

    Synopsis

    Tumor‐associated macrophages (TAMs) require the expression of the EMT transcription factor ZEB1 for their cancer‐promoting functions.

    • ZEB1 activates a F4/80low phenotype in macrophages and inhibits their maturation into F4/80high macrophages.

    • ZEB1 is required for the activation of macrophages toward pro‐tumor F4/80low TAMs.

    • ZEB1 induces a Ccr2‐Mmp9‐Ccl2 positive loop between TAMs and cancer cells to enhance tumor progression.

    • Expression of ZEB1 in TAMs and cancer cells correlates with poorer prognosis in human ovarian carcinomas.

    PKA1 inhibits PKG activity to prevent premature parasite exit from the host cell due to intracellular acidification.

    Synopsis

    In the human pathogen Toxoplasma gondii, the cAMP‐dependent protein kinase A1 (PKA1) prevents premature exit from the host cell induced by intracellular acidification. This is achieved by downregulating the activity of cGMP‐dependent protein kinase G (PKG).

    • PKAc1 is maintained inactive at the pellicle by interacting with the dually acylated PKAr.

    • Genetic perturbations of PKAc1 activity lead to premature egress of the parasite and unproductive invasion.

    • PKG inhibitors block premature egress caused by PKAc1 inactivation.

    • PKAc1 delays intracellular acidification–induced parasite exit from the host cell.

    • PKAc1 and pH act as balancing regulators of PKG signalling to control parasite egress.

    The methyl‐lysine reader L3MBTL3 switches the Notch coactivator RBPJ to a transcriptional repressor by mediating removal of activating histone marks at Notch target genes.

    Synopsis

    The methyl‐lysine reader L3MBTL3 interacts with the Notch co‐activator RBPJ and switches it to a transcriptional repressor via KDM1A demethylase‐mediated removal of activating histone marks at the enhancers of Notch target genes.

    • RBPJ physically and functionally interacts with L3MBTL3.

    • L3MBTL3 competes with NOTCH intracellular domain for binding to RBPJ and for the control of Notch signaling.

    • L3MBTL3 recruits histone demethylase KDM1A to repress Notch target gene expression.

    • Genetic analyses in Drosophila and Caenorhabditis elegans demonstrate that the RBPJ/L3MBTL3 link is evolutionarily conserved in metazoans.

    Embryonic germ cells are formed from embryonic progenitors through a highly complex differentiation process, recapitulation of which in vitro has proved challenging. Two new studies in The EMBO Journal report culture conditions for embryonic stem cell‐derived primordial germ cell‐like cells (PGCLCs) that enable global DNA demethylation (Ohta et al, 2017), and subsequent initiation of meiosis (Miyauchi et al, 2017), allowing future manipulations to elucidate mechanisms driving germ line differentiation.

    Two new studies establish conditions for culturing ESC‐derived germ cells, enabling global DNA demethylation and subsequent female sex determination.

    Yes‐associated protein activation triggers transcription of long noncoding RNA BCAR4, leading to GLI2‐mediated expression of key glycolytic enzymes.

    Synopsis

    Yes‐associated protein promotes cancer formation by reprogramming glucose metabolism. A long noncoding RNA BCAR4 is a key downstream effector of YAP, in regulation of glycolysis and tumorigenesis via GLI2‐mediated expression of key glycolytic enzymes.

    • BCAR4 is a direct transcriptional target of YAP.

    • BCAR4 promotes glycolysis by increasing the expression of HK2 and PFKFB3.

    • GLI2 activation is required for the expression of glycolytic enzymes downstream of BCAR4

    • High YAP and BCAR4 expression levels positively correlate in breast cancer patient samples and are linked to poor clinical outcomes.

    • Inhibition of BCAR4 via Locked Nucleic Acids (LNAs) attenuated YAP‐dependent glycolysis and tumor growth.

    Casein kinase isoforms CKIδ and CKIε facilitate Wnt‐mediated intestinal homeostasis and stem cell survival.

    Synopsis

    Casein kinase 1 (CKI) isoforms CKIδ and CKIε facilitate Wnt‐mediated intestinal homeostasis and stem cell survival.

    • Combined deletion of CKIδ/ε in the mouse intestine induces tissue atrophy and cell‐cycle arrest in p53‐independent manner.

    • Combined deletion of CKIδ/ε in Lgr5+ intestinal stem cells (ISCs) compromises self‐renewal, leading to Wnt inhibition and apoptosis.

    • Wnt suppression in ISCs is associated with reduced levels of nuclear Dvl and Fzd7 expression.

    • Exogenous expression of nuclear Dvl rescues CKIδ/ε ‐deleted organoids, which resume Fzd7 and Lgr5 expression.

    In vitro reconstitution of female sex determination using ESC‐derived germ cells demonstrates requirement of integrated signaling and epigenetic background for fetal oocyte induction.

    Synopsis

    In vitro reconstitution of female sex determination using ESC‐derived germ cells demonstrates requirement of integrated signaling inputs and epigenetic background for fetal oocyte induction.

    • Female mouse germ‐cell sex specification is reconstituted under a defined set of conditions.

    • Retinoic acid (RA) and its effector STRA8 are not sufficient to induce the fetal oocyte phenotype from ESC‐derived primordial germ cells.

    • Bone morphogenetic protein (BMP) and RA act synergistically to instruct female germ‐cell fate.

    • Cellular competence for acquiring female germ‐cell fate includes DNA demethylation of key genes.

    Ret maintains fly intestinal stem cells and mouse postnatal gut development.

    Synopsis

    Ret secures the proliferative capacity of adult fly intestinal stem cells (ISC) and mouse postnatal gut development.

    • The intestinal epithelium of both Drosophila and mouse expresses the Ret receptor tyrosine kinase.

    • Ret is autonomously required for ISC proliferation at homeostasis and under stress, and contributes to age‐related intestinal dysplasia.

    • Ret induces Src kinase activation, and maintains Wg/Wnt‐signaling in gut progenitors.

    • Organoids of Ret‐deficient mice exhibit branching defects and incomplete transition from foetal to adult tissue.
