Vascularized brain organoids enable reconstruction of the human blood-brain barrier and neurovascular disease modelling

This study establishes a scalable platform of vascularized human brain organoids that recapitulates the neurovascular unit and blood-brain barrier, enabling the investigation of human-specific BBB biology, development, and neurovascular diseases through in vitro and in vivo models.

Integrating Genomic and Fragmentomic Features for Tissue-of-Origin Prediction from Routine Targeted ctDNA Sequencing

This study introduces SHAPE, a novel method that leverages routine targeted ctDNA sequencing to integrate genomic and fragmentomic features for highly accurate, biologically interpretable prediction of cancer tissue-of-origin, potentially extending the clinical utility of existing assays without requiring additional sequencing.

Evidence that the perinatal maternal microbiome mediates metabolite signaling programs that drive sex-specific microglial metabolic alterations and Alzheimer’s disease susceptibility

This study demonstrates that perinatal disruption of the maternal microbiome selectively reduces Alzheimer's disease pathology in female offspring by reprogramming microglial metabolism and GPCR signaling pathways, thereby reversing the sex-specific susceptibility patterns typically observed with postnatal microbiome manipulations.

Comparative plastome genomics of Lobeliain the Mexican Transition Zone reveals conserved genome structure (Campanulaceae: Lobelioideae)

This study reveals that despite the Campanulaceae family's reputation for extensive plastome rearrangements, the Lobelia and Diastatea species in the Mexican Transition Zone exhibit highly conserved genome structures with only minor, species-specific variations, while phylogenetic analyses confirm the non-monophyly of section Stenotium.

MALAT1 is required for estradiol to act as a mitogen in hormone receptor-positive breast cancer

This study identifies the long noncoding RNA MALAT1 as a critical permissive regulator of estrogen-driven proliferation in hormone receptor-positive breast cancer, demonstrating that its depletion suppresses growth and induces cell death by disrupting the ME3-COX-2 axis.

Distinguishing insulators from enhancers by their ability to block long-range contacts using HiCAggR

The study introduces HiCAggR, a Bioconductor package that leverages high-resolution aggregation of Hi-C data to distinguish insulators from enhancers by quantifying their ability to block promiscuous long-range enhancer-promoter contacts, revealing that insulator depletion leads to aberrant contacts and widespread gene deregulation.

Mammalian Hemopexin Protects Blood-Feeding Dipterans from Heme Toxicity and Promotes Parasite Transmission

This study reveals that mammalian hemopexin taken up by blood-feeding dipterans retains its heme-scavenging activity to protect vectors from heme toxicity and maintain gut homeostasis, thereby inadvertently promoting the development and transmission of parasites like *Plasmodium* and *Leishmania*.

Conserved biological response states organize nanoparticle biosafety across neurological systems

This study introduces a response-centered machine-learning framework that integrates biological context and cellular response programs into a Conserved Response Axis (CRA), significantly improving the prediction of nanoparticle biosafety and recovery across diverse neurological systems beyond what material properties alone can achieve.

Scaffold Geometry Governs Mechanobiological Responses to Combined Biophysical Stimulation in Human Bone Tissue-Like Models

This study demonstrates that scaffold geometry dictates human bone marrow-derived mesenchymal stem cells' sensitivity to specific biophysical stimuli, but that combining intermittent hydrostatic pressure and pulsed electromagnetic field stimulation overcomes these geometric limitations to synergistically promote early osteogenesis through complementary molecular pathways.
