Clade-3 Bat Sarbecovirus PRD0038 Reveals Constraints on Coronavirus Emergence and Immune Sensitivity

This study characterizes the African clade-3 bat Sarbecovirus PRD0038, demonstrating its inability to infect human cells via ACE2, its susceptibility to existing antivirals and some antibodies, and its potential to utilize intermediate hosts, thereby defining the functional and immunological constraints that limit its emergence while highlighting available therapeutic countermeasures.

Biodiversity-forest structural diversity relationships differ among taxa

Using airborne lidar and field data across the United States and Puerto Rico, this study reveals that while forest structural diversity is a significant driver of taxonomic diversity for birds, mammals, and beetles, these relationships are taxon-specific and vary in strength and direction, unlike the weak association observed for plants.

Codon Usage Bias Shapes CpG Architecture in Millet Coding Sequences

This genome-wide analysis of six millet and related C₄ grass species reveals that synonymous codon usage bias actively shapes CpG dinucleotide architecture in coding sequences, suggesting that codon choice and arrangement preconfigure the structural substrate for gene body methylation and extend the functional role of codon bias beyond translational efficiency to include an epigenetic dimension.

Dysbiotic shifts in intestinal Streptococcus, Veillonella, and butyrate-producing bacteria are associated with disease severity in hepatitis E

This study utilizes shotgun metagenomic profiling to demonstrate that dysbiotic shifts characterized by an increased ratio of *Streptococcus* and *Veillonella*-associated species (sCAG5 and sCAG4) to butyrate-producing bacteria (sCAG10) serve as a novel intestinal microbial indicator of hepatitis E disease severity.

Low GROa/CXCL1 expression predicts poor outcome and promotes tumour progression in vivo and in vitro, revealing a context-dependent tumour-suppressive role in triple-negative breast cancer

This study demonstrates that low GROα/CXCL1 expression predicts poor survival and promotes tumor progression in triple-negative breast cancer, revealing a context-dependent tumor-suppressive role that warrants further investigation as a prognostic biomarker and therapeutic target.

Genome-wide identification, structural characterization and gene expression analysis of CYP450 family under different light-conditions in Coptis chinensis

This study comprehensively identifies and characterizes 283 CYP450 genes in *Coptis chinensis*, revealing their uneven chromosomal distribution, tissue-specific expression, and significant upregulation under low-light and long-photoperiod conditions, which suggests a regulatory role in alkaloid accumulation mediated by light-responsive and MeJA elements.

Brain-region-aware genetic prioritization separates Alzheimer disease risk from APOE-sensitive β-amyloid burden in public genetic and expression quantitative trait locus resources

By integrating public genetic and expression resources, this study demonstrates that Alzheimer's disease risk and β-amyloid burden represent distinct biological processes, identifying BIN1 as a broad risk anchor while showing that the previously implicated ZNF227 signal is primarily driven by APOE-region variants rather than independent amyloid pathology.
