Single-nucleus RNA sequencing from the dorsolateral prefrontal cortex of 424 aging individuals, and mapping the effect of genetic variation on gene expression, identified a large number of cis-expression quantitative trait loci at the level of cell types and cell subtypes.

Single-cell RNA sequencing analysis of over 800,000 human adult breast cells from 55 female donors identifies 41 cell subtypes and highlights age- and parity-dependent effects. Samples from healthy women with germline mutations in BRCA1 or BRCA2 showed signs of T cell exhaustion.

The transcription factor double homeobox protein (DUX) induces a totipotency-specific regulatory program, including the upregulation of DUXBL. DUXBL subsequently accesses DUX-bound regions and interacts with TRIM24 and TRIM33, thus contributing to totipotency exit.

Chromosome-level genome assemblies of 11 bamboo species comprising lineages from diploid (herbaceous) to tetraploid and hexaploid (woody) provide insights into dynamic subgenome dominance in bamboos.

Multi-ancestry genome-wide analyses identify 95 loci associated with post-traumatic stress disorder and implicate candidate genes, pathways and neurobiological systems underlying its pathophysiology.

Analysis of genetic modifiers of 599 developmental disorder genes in the UK Biobank found that rare variant burden within this set, as well as the common polygenic background, can alter the expressivity of cognitive and socioeconomic traits in an additive manner.

A multi-ancestry genome-wide association study of liver cirrhosis and its associated endophenotypes identifies and validates 14 risk variants. Integrative common and rare variant analyses provide insights into the genetic architecture of liver cirrhosis.

A single-cell-based approach allows the daughters of a damaged cell to be separately tracked following single mitotic events. This technique highlights the different ways in which ultraviolet light and reactive oxygen species cause mutagenesis.

A comprehensive time series characterization of a mouse model of cholestatic liver injury with spatial enhanced resolution omics sequencing and single-cell RNA sequencing identifies zonal responses to insult, such as cholangiocyte signaling recruiting lipid-associated macrophages.

A Stereo-seq and scRNA-seq atlas of mouse liver in homeostasis and regeneration after partial hepatectomy identifies zonated genes, pathways, cell–cell interactions and gene regulatory networks. Functional validation finds that cooperation between TBL1XR1 and β-catenin activates hepatocyte proliferation.
