Transcriptome profiling of neurexin- and neuroligin-deficient Caenorhabditis elegans reveals pathways underlying developmental and behavioral dysfunction

This study demonstrates that neurexin and neuroligin deficiency in *C. elegans* causes widespread transcriptional reprogramming affecting diverse pathways beyond synaptic function, thereby linking molecular dysregulation to the observed developmental, behavioral, and neuromorphological abnormalities.

Biallelic mutations in SUPV3L1 cause a variable leukodystrophy due to impaired mitochondrial degradosome function

This study defines the clinical and radiological spectrum of a variable leukodystrophy caused by biallelic SUPV3L1 mutations, demonstrating that the loss of this mitochondrial degradosome component leads to neurodevelopmental impairment and microcephaly through the dysregulation of type I interferon signaling.

PTEN Downregulation and NOTCH1 Upregulation Define Conserved Molecular Signatures of Oral Squamous Cell Carcinoma Across Distinct Indian Populations

This study identifies PTEN downregulation and NOTCH1 upregulation as conserved molecular signatures of oral squamous cell carcinoma across distinct Indian populations (Gujarat and Telangana), suggesting their potential as robust, geography-independent biomarkers for the disease.

Phosphorylation of RPS6 at Ser235 and Il-6 Release Emerge as Components of a Peripheral Inflammatory Signature in Parkinson’s Disease Manifestation

This study identifies phosphorylation of ribosomal protein S6 at Ser235 and increased IL-6 release in peripheral blood mononuclear cells as a distinct inflammatory signature that correlates with clinical severity and distinguishes manifesting Parkinson's disease from non-manifesting states across both idiopathic and LRRK2-associated forms.

Entropy-Based Indicators of Critical Transitions in Power-Law Networks Under Progressive Node Removal

This paper proposes and validates a smoothed successive Kullback-Leibler divergence of degree distributions as an effective early-warning signal for critical transitions in power-law networks, demonstrating its ability to detect impending collapse earlier than traditional connectivity measures under random node removal while providing immediate disruption summaries under targeted attacks.

Correlation of Prefrontal Cortex Connectivity and Vestibulo-Ocular Reflex with Motor Skills and Functional Performance in Children with Cerebral Palsy

This cross-sectional study of children with spastic diplegic cerebral palsy reveals that while altered prefrontal cortex EEG activity correlates with social function, vestibulo-ocular reflex parameters do not directly associate with motor or functional performance, highlighting the multifactorial nature of motor impairment in this population.

Metagenomic characterization of viral communities across coastal matrices highlights bivalves as integrative sentinel hosts within a One Health framework

This study utilizes metagenomic sequencing across coastal water, bivalves, and marine mammals to demonstrate that filter-feeding bivalves serve as effective integrative sentinel hosts for monitoring diverse and dynamic viral communities, thereby supporting One Health surveillance and early detection of zoonotic risks.

Acute severe hypoxia induces prolonged cardiac transcriptomic remodeling despite rapid functional recovery

Although adult zebrafish hearts rapidly recover their electrical function following acute severe hypoxia, transcriptomic analysis reveals that significant molecular remodeling and stress responses persist for at least seven days, demonstrating that functional recovery does not equate to immediate molecular normalization.

First complete mitogenome of Clinostomum dimorphum reveals conserved genomic features and phylogenetic relationships within Clinostomidae

This study presents the first complete mitochondrial genome of the Amazonian fish parasite *Clinostomum dimorphum*, generated via hybrid sequencing to resolve complex regions, and reveals conserved genomic features alongside lineage-specific evolutionary patterns that clarify phylogenetic relationships within the Clinostomidae family.
