Evaluation of ensilication technology for ambient DNA preservation

2 weeks 3 days ago
Current nucleic acid preservation relies on ultra-low temperature storage (-20°C to -80°C), imposing significant infrastructure, cost, and accessibility barriers that limit genomic medicine worldwide. We present a comprehensive evaluation of ensilication, a silica-based encapsulation method enabling ambient-temperature preservation of DNA without compromising sequencing fidelity. Across clinical, genomic, and biochemical analyses, ensilication maintained complete diagnostic concordance with...

RNA-Binding Proteins TDP-43 and FUS Promote R-Loop Resolution and Regulate Transcription Termination

2 weeks 3 days ago
TDP-43 and FUS are RNA-binding proteins involved in the regulation of diverse RNA processing events and have been strongly implicated in neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). We have previously demonstrated the role of symmetrical dimethylation (me2s) of a conserved arginine residue (R1810 in human POLR2A) in the C-terminal domain (CTD) of RNA polymerase II (RNAPII), which facilitates the recruitment of the Tudor...

RELN biallelic variant as a candidate risk factor in a consanguineous Pakistani family with bipolar disorder and clinical heterogeneity

3 weeks ago
CONCLUSION: Based on the clinical and genetic data, the present familial study revealed the plausible contribution of a novel variant of RELN in association with BD in the affected family. The present study's findings are valuable in understanding the genetic basis of the multifactorial phenotype BD and pave a better path for future functional studies.

Novel monoclonal antibodies against the C-terminal HEAT domain of huntingtin

3 weeks ago
BackgroundReliable detection of huntingtin (HTT) is essential for understanding Huntington's disease (HD) biology and for evaluating therapeutic strategies. However, high-quality monoclonal antibodies (mAbs) against the HTT C-terminal domain remain limited.ObjectiveWe sought to generate and validate novel monoclonal antibodies targeting the HTT C-terminal HEAT-containing domain to better detect HTT independently of potential effects of polyglutamine length that can impact some N-terminally...

Mapping the inter- and intra-genic codon-usage landscape in <em>Homo sapiens</em>

3 weeks ago
Although the genetic code is degenerate, codon selection is nonrandom and reflects significant functional constraints. Codon-usage bias (CUB) acts as a layer of post-transcriptional regulation, influencing messenger RNA (mRNA) stability, translation kinetics, and co-translational protein folding. While CUB is well-characterized in unicellular organisms, its regulatory scope and functional consequences in humans remain complex and less defined. Our study offers a comprehensive evaluation of human...

A crowdsourced megastudy of 12 digital single-session interventions for depression in US adults

3 weeks 3 days ago
Digital, self-guided, single-session interventions (SSIs) deliver structured psychological support within one interaction. Here we crowdsourced 66 diverse 10-min SSIs for depression and, with input from researchers and lived-experience experts, selected 11 for testing in a preregistered online randomized controlled trial (ClinicalTrials.gov ID: NCT06856668 ). US adults (N = 7,505) experiencing elevated depressive symptoms were randomly assigned to 1 of the 11 crowdsourced SSIs, a validated...

Delineating the trajectory of adult chronic diseases and healthcare use for 22q11.2 microdeletion in a general population context

3 weeks 3 days ago
CONCLUSION: A population-based approach provided new evidence for accumulating illnesses over young adulthood, supporting the need for novel models of anticipatory care for adults with 22q11.2 microdeletion. A similar genetics-first strategy, defining cohorts with shared genetic changes, may facilitate understanding of premature aging mechanisms relevant to the general population.

Training outcomes in a transdiagnostic, neuropsychologically - informed parenting intervention for children with early brain injury

3 weeks 5 days ago
RESEARCH AIMS: The benefits of parenting interventions for child and family outcomes following pediatric brain injury are well documented. However, training in pediatric neuropsychology largely emphasizes a focus on assessment, as well as syndrome- or disorder-specific interventions. Greater attention to transdiagnostic intervention is warranted, particularly pediatric neurorehabilitation programs that are family-centered and evidence-based. This study evaluated the acceptability of a didactic...

React-to-Me: A Conversational Interface for Interactive Exploration of the Reactome Pathway Knowledgebase

3 weeks 6 days ago
The Reactome Pathway Knowledgebase (www.reactome.org) provides expert-curated information on human biological pathways, molecular interactions, and disease mechanisms. However, its complex data model and keyword-based search interface present accessibility barriers for non-expert users. In contrast, general-purpose conversational AI systems offer intuitive natural language interfaces but lack the domain-specificity, transparent sourcing, and factual reliability required for scientific...

Lifelong <em>n</em>-3 PUFA Consumption Reduces HER2+ Mammary Tumour Growth and Alters Immune Markers Compared to Safflower- or Corn Oil-Based Sources of <em>n</em>-6 PUFA

3 weeks 6 days ago
CONCLUSIONS: These findings indicate that the presence of dietary n-3 PUFA plays a key role in modulating mammary tumour development, which may be further influenced by the underlying n-6 PUFA background. The associated changes in immune markers suggest that n-3 PUFA exert anticancer effects in part by shifting the tumour immune microenvironment toward an anti-tumour phenotype and modulating cannabinoid receptor signalling. Collectively, this work informs future human studies investigating the...

HTD1265 Disrupts GimC-Dependent Cellular Processes in <em>Saccharomyces cerevisiae</em>

3 weeks 6 days ago
HTD1265 is a newly identified antifungal compound that displays potent activity against Candida krusei, a clinically challenging non-albicans species. To elucidate its mechanism of action, we applied an integrative phenotypic approach combining high-resolution morphological profiling, pathway inference, and genetic validation in Saccharomyces cerevisiae. Morphological signature extraction revealed a characteristic defect in nuclear positioning upon HTD1265 treatment. Integration of nuclear...
