Identification of Grem2⁺ Dental Follicle Stem Cells in Alveolar Bone Homeostasis and Molar Morphogenesis

This study identifies Grem2⁺ dental follicle stem cells as a distinct, endogenous progenitor population essential for alveolar bone homeostasis and molar morphogenesis, revealing that Grem2-mediated regulation of BMP and IGF2 signaling prevents premature stem cell exhaustion and ensures proper bone formation.

Reduced CXCL1 expression promotes context-dependent tumour aggressiveness in triple-negative breast cancer

This study reveals that contrary to expectations, reduced CXCL1 expression in triple-negative breast cancer promotes tumor aggressiveness and correlates with poor patient survival, suggesting a context-dependent tumor-restraining role for this chemokine.

Drought and salinity recruit largely distinct lncRNAs in sunflower, converging on a compact dual-responsive core

This study establishes the first abiotic-stress lncRNA framework for sunflower, revealing that drought and salinity recruit largely distinct non-coding RNA populations converging on a compact dual-responsive core involving jasmonate signaling and water-channel activity, with genotype-specific mRNA partner responses offering candidates for resilience breeding.

Profile-HMM validation reveals annotation-derived inflation of apparent two-domain NucS occurrence and taxonomically concentrated NucS/MutS-MutL coexistence across 23,435 prokaryotic reference genomes

This study demonstrates that relying solely on genomic annotations significantly inflates estimates of two-domain NucS occurrence and NucS/MutS-MutL coexistence across prokaryotes, whereas validation with profile hidden Markov models reveals that such coexistence is rare and taxonomically concentrated primarily in Halobacteria and Deinococcota.

A T2T genome assembly of subtropic maize inbred line CML312 with Nanopore simplex reads

This study presents a cost-effective, near-complete telomere-to-telomere genome assembly and comprehensive annotation of the subtropical maize inbred line CML312 using only standard Nanopore simplex reads, providing a scalable paradigm for complex plant genome assembly and a critical resource for mining stress-tolerance alleles.

Connectomic disturbances in ADHD: A systematic review of MRI-based global and nodal topology

This systematic review and meta-analysis of 31 MRI datasets reveals that individuals with ADHD exhibit significantly reduced global efficiency in structural brain networks, indicating compromised information integration, alongside exploratory evidence of nodal abnormalities in key regions like the caudate and orbitofrontal cortex.

Engineering of LRP1-targeted peptide condensate with up-concentration regulatory effects in MASH

This study demonstrates that an LRP1-targeted block peptide engineered to form liquid-liquid phase separation condensates on the cell surface significantly amplifies receptor signaling and therapeutic efficacy, effectively alleviating hepatic inflammation, lipid dysfunction, and fibrosis in a mouse model of metabolic dysfunction-associated steatohepatitis (MASH).
