Transcriptional heterogeneity predicts and enables clonal selection in ageing haematopoiesis

This study demonstrates that transcriptional heterogeneity, rather than mean gene expression, predicts clonal selection in ageing haematopoiesis by revealing that increased variability in stem cell gene expression programs drives the expansion of specific clones and is conserved across species as a marker for myeloid malignancy risk.

Lobe-resolved transcriptomic profiling of post-pneumonectomy lung growth reveals Fgfr2b-dependent epithelial maintenance and control of fibrotic remodeling

This study demonstrates that compensatory lung growth following pneumonectomy is a regionally specific process driven by Fgfr2b signaling, which is essential for maintaining epithelial integrity and preventing fibrotic remodeling, with an embryonic Fgfr2b-responsive signature that is diminished in human lung diseases.

The Gini coefficient as a surrogate for the regulability or homeostasis of metabolite concentrations: focus on ergothioneine

This paper proposes that the Gini coefficient serves as a useful non-parametric metric to assess the regulability and origin of metabolites, demonstrating that tightly regulated endogenous compounds exhibit low coefficients while exogenous substances show higher values, with ergothioneine displaying intermediate variability indicative of its dietary origin.

Intraspecific variation in mycorrhiza-associated traits predicts plant growth and stress tolerance under resource limitation

This study demonstrates that intraspecific variation in pre-existing arbuscular mycorrhizal fungal colonization patterns and associated root traits, such as root diameter and tissue density, is critical for predicting drought and nutrient stress tolerance in alfalfa and sainfoin.

Effect of smoke-derived compounds on the germination of Cerrado ground layer species

This study demonstrates that smoke-derived compounds, specifically karrikin 1 and mandelonitrile cyanohydrin, can stimulate or inhibit the germination of Cerrado ground-layer species in a concentration- and species-dependent manner, offering potential applications for ecological restoration.

ISGylation of STING contributes to neuroinflammation and neurodegeneration via activating c-Fos in Parkinson's disease models

This study demonstrates that ISGylation of STING drives neuroinflammation and dopaminergic neuronal death in Parkinson's disease models by activating c-Fos through a positive feedback loop, suggesting that targeting this ISG15-STING axis offers a novel therapeutic strategy.
