Schwannomas are regularly treated with radiotherapy, but the molecular effects on these tumours and their microenvironment remain unclear. Here, the authors show that radiotherapy can induce epigenetic reprogramming and immune infiltration in schwannomas, and develop the snARC-seq approach to analyse the epigenomic evolution at the single-cell level.

Analysis of 97,691 high-coverage human blood DNA-derived whole-genome sequences enabled simultaneous identification of germline and somatic mutations that predispose individuals to clonal expansion of haematopoietic stem cells, indicating that both inherited and acquired mutations are linked to age-related cancers and coronary heart disease.

Clear-cell carcinomas are aggressive tumours characterised by high accumulation of lipids and glycogen. Here, the authors report that these cancers have a common vulnerability to GPX4 inhibition-induced ferroptosis and using CRISPR screen and lipodomic profiling, they identify HIF-2α- HILPDA axis promotes ferroptosis via enrichment of PUFA lipids.

MetaSTAAR enables functionally informed rare variant association analysis in biobank-scale cohorts using an efficient, sparse matrix approach for summary statistic storage.

This overview of the ENCODE project outlines the data accumulated so far, revealing that 80% of the human genome now has at least one biochemical function assigned to it; the newly identified functional elements should aid the interpretation of results of genome-wide association studies, as many correspond to sites of association with human disease.

Most studies of the genetics of the metabolome have been done in individuals of European descent. Here, the authors integrate genomics and metabolomics in Black individuals, highlighting the value of whole genome sequencing in diverse populations and linking circulating metabolites to human disease.

Preliminary and exploratory analyses show that a third dose of the COVID-19 vaccine mRNA-1273 or variant-modified boosters can boost levels of neutralizing antibodies against SARS-CoV-2 variants.

A genome-wide association study identifies 17 genetic loci that are associated with the risk of myeloproliferative neoplasms (MPNs), and shows that the modulation of haematopoietic stem cell function drives MPN risk.

Platelet aggregation is associated with myocardial infarction and stroke. Here, the authors have conducted a whole genome sequencing association study on platelet aggregation, discovering a locus in RGS18, where enhancer assays suggest an effect on activity of haematopoeitic lineage transcription factors.

A study shows that clonal haematopoiesis of indeterminate potential is associated with an increased risk of chronic liver disease specifically through the promotion of liver inflammation and injury.

Breast cancer risk for BRCA1/BRCA2 mutation carriers varies depending on other genetic factors. Here, the authors perform a case-only genome-wide association study and highlight novel loci associated with breast cancer risk for BRCA1/BRCA2 mutation carriers.

A cell-based phenotypic screen identifying inhibitors of Notch signaling led to the discovery of NVS-ZP7-4, which blocks the activity of the zinc transporter SLC39a7 (ZIP7) and induces cell death through an ER stress mechanism.

The long-term stability of the continents has been attributed to a trade-off between thermal and compositional effects. Numerical simulations of the evolution of continents over 3 billion years, however, show that this state is ephemeral, and continents that are neutrally buoyant today were more (or less) buoyant in the geologic past.

Narcolepsy has genetic and environmental risk factors, but the specific genetic risk loci and interaction with environmental triggers are not well understood. Here, the authors identify genetic loci for narcolepsy, suggesting infection as a trigger and dendritic and helper T cell involvement.

Karin Tuschl, Philippa Mills and colleagues report mutations in the manganese (Mn) transporter gene SLC39A14in childhood-onset parkinsonism-dystonia. Using functional recapitulation, the authors also show that slc39A14 loss-of-function in zebrafish can lead to Mn dysregulation and locomotor impairment.

The mechanisms regulating central nervous system remyelination efficiency are poorly understood. Here, the authors show that remyelination is driven by astrocytes supporting oligodendrocyte survival, regulated by the Nrf2 and cholesterol pathways.

Primary open-angle glaucoma (POAG) is highly heritable, yet not well understood from a genetic perspective. Here, the authors perform a meta-analysis of genome-wide association studies in 34,179 POAG cases, identifying 44 previously unreported risk loci and mapping effects across multiple ethnicities.

A previous human HIV-1 vaccine clinical trial, boosting with HIV envelope protein from two strains, demonstrated moderate vaccine efficacy. Here, Bradleyet al. show that a pentavalent HIV envelope protein boost improves protection from viral challenge in non-human primates and they identify immune correlates of protection.

Pooling participant-level genetic data into a single analysis can result in variance stratification, reducing statistical performance. Here, the authors develop variant-specific inflation factors to assess variance stratification and apply this to pooled individual-level data from whole genome sequencing.

A third dose of the COVID-19 vaccine mRNA-1273 is safe and boosts SARS-CoV-2 neutralizing antibody titers almost two-fold higher than the peak levels observed after completion of a two-dose series, highlighting the potential clinical benefit of a booster dose.

Nitrile-oxide electrophiles were identified as covalent inhibitors of GPX4 that exhibit increased selectivity and reduced off-target effects relative to chloroacetamide-based inhibitors.

Resident microglia in the central nervous system are identified as the specific macrophage population that regulates myelin growth and integrity.

Recently triggered seismic events such as the Pohang earthquake have exceeded predictions of average energy releases by a factor of 1000. A new framework is proposed to define maximum event magnitudes as a function of pre-existing critical stresses and fluid injection volume.

Jen Jen Yeh and colleagues apply statistical methods to separate tumor, stroma and normal tissue gene expression signatures from pancreatic ductal adenocarcinoma expression profiling data sets. They identify and validate two tumor-specific and two stroma-specific subtypes, which are associated with different clinical outcomes.

Using genome-wide CRISPR–Cas9-mediated suppressor screens, cytochrome P450 oxidoreductase was identified as a contributor to ferroptotic cell death by promoting phospholipid peroxidation in various cellular lineages.

Decoquinate is a drug used in veterinary practice, which displays antimalarial activity in vitro but has poor bioavailability. Here, the authors convert decoquinate into more soluble amide and carbamate derivatives and assess their efficacy against tuberculosis bacteria and apicomplexan parasites.

STAAR is a powerful rare variant association test that incorporates variant functional categories and complementary functional annotations using a dynamic weighting scheme based on annotation principal components.
