Targeting PML in acute promyelocytic leukaemia has changed the outcome of patients with this disease. Here, the authors demonstrated that PML is also a potential therapeutic target in breast cancer where it specifically regulates cancer initiating cells and tumour progression through the transcriptional regulation of SOX9.

Glioma-associated microglia/macrophages are central drivers of brain tumor pathology. Here the authors characterize the role of the P-selectin/PSGL-1 axis in the cross-talk between glioblastoma cells and microglia/macrophages and show that the therapeutic targeting of P-selectin limits glioblastoma progression in preclinical models.

In an observational study evaluating functional precision medicine in children and adolescents with relapsed or refractory solid and hematologic malignancies, it was feasible to provide personalized treatment recommendations to treating physicians on the basis of genomic profiling and ex vivo drug sensitivity testing within 4 weeks.

Activation of breathing during hypoxia is abolished in mice lacking mitochondrial complex I in carotid body chemoreceptors, however the specific contribution of mitochondrial complex I to this process is unclear. Here, the authors show that recovery of NADH dehydrogenase activity, but not proton pumping, by transgenic expression of a yeast enzyme rescues cellular and systemic sensitivity to changes in O2 tension.

Local microbiome composition influences treatment efficacy of chemotherapy in colon cancer via modulation of tolerogenic versus immunogenic ileal intestinal epithelial cell death, which in turn influences follicular helper T cell priming.

SMARCA4 is commonly inactivated in lung and ovarian cancers. Here the authors show that SMARCA4-deficient tumours have significantly reduced levels of the histone demethylases KDM6s and a strong dependency on these demethylases for tumour growth, so that they are vulnerable to KDM6s inhibition.

RAS isoforms are associated with the plasma membrane and endomembranes, but how their localization contributes to tumorigenesis is unclear. Here, the authors show that RAS signals from Golgi complex antagonize tumour formation by inducing apoptosis via ERK inhibition.

Gutierrez-Martinez et al. show that an impaired DNA damage response and reduced apoptotic priming in old haematopoietic stem cells (HSCs) contribute to the survival and expansion of damaged HSCs in the bone marrow of aged mice.

Here the authors report results from a randomized clinical trial testing a combination of ChAOx1/MVA.HTI vaccines and the TLR7 agonist vesatolimod in men living with HIV-1. While the treatment showed a good safety profile and induction of HTI-focused T-cell responses, viral rebound was similar in treatment arm and placebo arm.

Cell cycle checkpoint kinase, MK2, is in synthetic relationship with p53 in the DNA damage response to chemotherapeutic agents. Here, the authors report XPA as a third gene in which simultaneous targeting of MK2 and XPA further enhances sensitivity to cisplatin in p53-deficient tumours.

Merbl and colleagues demonstrate that high expression of the proteasome regulator PSME4 is associated with immune-cold lung tumors and reduced antitumor immune responses, by functioning to modulate the protein degradome and antigen diversity.

Viruses are promising anti-tumour therapeutics due to induction of an immune response and/or oncolytic activity. Here, Kalkavanet al. show that LCMV replicates in tumour cells, without inducing cell lysis, and that its anti-tumour activity is largely mediated by recruitment of interferon-producing monocytes.

Telomerase deficiency leads to age-related diseases and shortened lifespan, while inhibition of the mTOR pathway delays aging. Here, the authors show that inhibition of mTORC1 signaling shortens the lifespan of telomerase deficient mice.

Defective proteins or functional proteins that are no longer needed can be degraded in the endoplasmic reticulum. In this study, Lopez-Serra et al.show that DERL3, which is involved in protein degradation in the endoplasmic reticulum, is aberrantly silenced in cancer, leading to activation of a glucose transporter and dysregulated glycolysis.

Chemotherapy resistance in recurrent gliomas is a large hurdle for successful therapy. Here, the authors show that some recurrent gliomas harbour O-6-methylguanine-DNA methyltransferase (MGMT) genomic rearrangements, and in vitro and in vivo these contribute to temozolomide resistance.

The LHCb experiment at CERN has observed significant asymmetries between the decay rates of the beauty baryon and its CP-conjugated antibaryon, thus demonstrating CP violation in baryon decays.

Treatment of pancreatic ductal adenocarcinoma is still challenging and patients survival has only marginally improved in the last decade. Here the authors produce a PGA-based polymeric nanocarrier for the dual delivery of miR-34a-mimic and PLK1-targeting siRNA resulting in killing of pancreatic cancer cells in vivo.

A mouse model of Down syndrome (DS) highlights the importance of triplication of the IFNR gene cluster for a variety of DS-associated traits. Copy number correction resulted in amelioration of multiple phenotypes associated with the condition.

Here, Burk et al. develop an algorithm to diagnose bacterial vaginosis (BV) using the 16S rRNA gene, called molBV, which they use to profile the inflammatory landscape of BV and predict progression of human papillomavirus infection to cervical pre-cancer.

Epigenetic inactivation of a Rab GTPase activating protein confers metastatic properties in melanoma, and it correlates with poor prognosis but better sensitivity to therapy by targeting EGFR signaling.

The consequences of postprandial IL-1β surges in white adipose tissue are unknown. Here the authors show IL-1β regulates WAT remodelling by promoting adipogenesis and energy storage, which is blocked by chronic elevation of this cytokine (as in obesity).

Bakke, Bousquet et al. identify serum metabolite biomarkers at the time of primary tumour diagnosis in rectal cancer participants prone to metastatic progression. These individuals show higher serum metabolites of alanine, lactate, pyruvate, and citrate compared to those without metastatic progression.

Rodrigues et al. show that exosomal CEMIP derived from brain metastatic cells elicits vascular remodelling and inflammation and supports subsequent metastatic colonization in the brain microenvironment.

Little is known about the mechanisms by which breast cancer cells metastasize to the brain. By performing gene expression analysis on cells that preferentially infiltrate the brain it has now been possible to identify three genes that are involved in this process, two of which—COX2 and HBEGF—have previously been shown to mediate breast cancer metastasis to the lung.

Sottoriva and colleagues combine next-generation sequencing and AI-aided histopathology to assess tumor evolvability in patient samples with long-term follow-up and find that it can be a strong predictor of recurrence in high-risk prostate cancer.

Post-neoadjuvant treatment options for patients with triple-negative breast cancer (TNBC) include the chemo-drug capecitabine but also immune checkpoint inhibitors. Here the authors report the results of a phase II study of adjuvant nivolumab, capecitabine or the combination in patients with residual TNBC.

This analysis of a large, clinically annotated cohort of individuals with predisposition to myelodysplastic syndromes reveals insights into the genetic determinants of disease progression and their relationship with clinical manifestations and therapy outcome.

Grant Stewart, Andrew Jackson, Christopher Mathew, Fowzan Alkuraya and colleagues identify a novel replication fork protein, DONSON, which is important for maintaining genome stability. Mutations in DONSON cause microcephalic dwarfism and lead to stalled replication forks and DNA damage.

A genome-wide association study suggests 41 previously unreported loci on top of the 23 known loci that influence the disease risk for lumbar disc herniations. Many of these loci harbour genes implicated in disc structure and inflammation, as well as genes related to the nervous system and nerve function.

An inflammatory-fibrotic tumor microenvironment supports metastatic disease progression in pancreatic ductal adenocarcinoma (PDAC). Here the authors show that metastasis-infiltrating macrophages influence metastasis-associated fibroblast (MAF) heterogeneity in liver metastatic PDAC, by promoting JAK/STAT signalling pathway activation in MAFs.

A new framework enables a pan-cancer reference set of copy number signatures derived from allele-specific profiles from different experimental assays.

Li et al. show how mitochondrial content is regulated when oxygen is depleted, as well as how this process is impaired in cancer types related to the von Hippel–Lindau syndrome.

Sul-2 is a steroid sulfatase in c.elegans. Here the authors show that, in the absence of sul-2 enzymatic activity, worm lifespan is increased, and that chemical inhibition ameliorates symptoms of neurodegenerative disorders in worms and mice.

Biallelic mutations in the sorbitol dehydrogenase gene SORD are identified as a common cause of hereditary neuropathy. Functional studies suggest that SORD deficiency may be treatable with aldose reductase inhibitors.

Metabolic rewiring of cancer cells can be driven by both extrinsic and intrinsic factors. Here the authors show that microenvironmental factors induce metabolic rewiring of B-cell lymphoma through activation of STAT3 and NF-ΚB resulting in upregulation of the aminotransferase GOT2 and glutamine addiction.

Medulloblastomas lacking p53 do not express surface class I major histocompatibility complex (MHC-I) and are resistant to immune rejection. Tumor necrosis factor rescues MHC-I expression and synergizes with immune checkpoint inhibitors to promote rejection.

Duchenne muscular dystrophy is a disease caused by a single gene, characterized by progressive muscle weakness, but is variable between patients partly due to interactions of other genes. Here, the authors show that a commonACTN3polymorphism can modify the clinical phenotype.

Here, Hitesh S. Deshmukh et al. report that in neonates, establishment of the intestinal microbiota is associated with neutrophil development. Antibiotic-treated and germ-free mice have reduced numbers of neutrophils and are susceptible to Escherichia coli K1 and Klebsiella pneumoniae sepsis. Reconstitution of the intestinal microbiota promotes interleukin-17 production by innate lymphoid cells and increases plasma granulocyte colony–stimulating factor levels, granulocytosis and host resistance to sepsis.
