Statistical fine-mapping of mRNA and protein quantitative trait loci in blood samples from the Japan COVID-19 Task Force sheds light on regulatory mechanisms and disease associations.
Phylogenetic analysis of trait heritability (PATH) applies phylogenetic correlations to single-cell lineage tracing data, quantifying cell state plasticity and transition probabilities. PATH offers insights into cell state heritability and transition dynamics in cancers.
Phenome-wide analysis in the UK Biobank identifies GC-rich tandem repeat expansions associated with a range of traits, including a GCC expansion in AFF3 contributing to intellectual disability.
Epithelioids are genetically stable, self-sustaining three-dimensional cultures. They may be used to investigate various aspects of epithelial biology over several months without need for passaging. In this paper, mouse epithelioids are used to identify drivers of clonal expansion in the esophagus.
Analysis of autosomal recessive coding variants in 29,745 trios from the DDD study and GeneDx provides insights into the genetic architecture of developmental disorders across ancestrally diverse populations.
Blockade of primary genomic binding sites with small molecules causes redistribution of the transcription factor PU.1 to alternative binding sites; its transcriptional activity at these sites activates secondary gene networks that drive myeloid cell differentiation.
A large-scale multi-ancestry genome-wide association study of European, African, admixed American, South Asian and East Asian ancestries provides insights into the pathogenesis of anxiety disorders.
Chemically driven blockade of PU.1 binding sites leads to its genome-wide redistribution. PU.1 network rewiring causes human acute myeloid leukemia cells to differentiate.
Spot-based spatial transcriptomic analysis of paired primary and metastatic pancreatic cancers identifies cellular, metabolic and fibrotic changes in ecotypes associated with progression, highlighting the contribution of the tumor microenvironment.
R-loops contain DNA:RNA hybrids and an unpaired single-stranded DNA. N6-methyladenosine (m6A) has been reported to modulate R-loop levels, but with varying outcomes (R-loop resolution versus stabilization). We propose that in different contexts, m6A may either directly prevent R-loop accumulation or stabilize R-loops via the formation of RNA abasic sites.
CREME is an extensible computational tool for investigating cis-regulation via in silico perturbations of neural network-based DNA sequence models such as Enformer, identifying complex interactions between a gene’s regulatory elements.
Single-cell profiling of lamina-associated domains (LADs) during early mouse development reveals an overlap between preimplantation-specific LAD dissociation and noncanonical broad H3K27me3 domains. Loss of H3K27me3 restores canonical LAD profiles.
Analysis of human tumor datasets shows that all features that appear significantly associated with immunotherapy response and survival may be collapsed into five latent factors: tumor mutation burden, T cell effective infiltration, TGF-β activity in the microenvironment, prior treatment and tumor proliferative potential.
Massively parallel reporter assays in four plant species show that transcriptional regulatory elements are position dependent with enrichment downstream of the transcription start site, particularly GATC motifs with strong effects in vascular plants.
MILTON uses phenotype information in the UK Biobank to identify clinical biomarkers and other quantitative traits that characterize diseases. It then constructs augmented cohorts by predicting undiagnosed individuals, improving power to discover gene–disease relationships.
