Angiotensin Peptides and SARS-CoV-2 Spike Binding
2026-09-02
A 2025 study found that naturally occurring angiotensin fragments can enhance SARS-CoV-2 spike-protein binding to host receptors, with sequence length and tyrosine modification influencing the effect. The findings connect renin-angiotensin system peptide biology with viral receptor engagement, while remaining limited to antibody-based binding assays rather than infection or clinical studies.

PDX1 Mutations, Pancreatic Agenesis, and m6A
2026-09-02
Zhang et al. developed PDX1-mutant cynomolgus macaques to model pancreatic agenesis and MODY4-related developmental defects in a species with closer anatomical and genomic relevance to humans. Their combination of primate phenotyping, transcriptomics, m6A profiling, islet organoids, and METTL3 rescue experiments identifies altered m6A regulation as a potentially important layer of PDX1 haploinsufficiency biology.

Hydroxychloroquine Sulfate Workflow Guide
2026-09-01
Hydroxychloroquine Sulfate (SKU B4874) provides an aqueous research reagent for examining autophagy pathway modulation and TLR7/9-associated immune responses in autoimmune disease research. It is appropriate for short-term, water-based workflows, but not for protocols requiring DMSO or ethanol stocks or long-term storage of prepared solutions.

NEXMIF Overexpression, Synapses, and Autism-Like Behavior
2026-09-01
A 2025 Frontiers in Neuroscience study tested the consequences of increasing human NEXMIF dosage in mice, addressing a gap left by earlier work focused largely on NEXMIF loss of function. The model linked overexpression to autism-like behaviors, altered dendritic structure, reduced spine density, and transcriptomic disruption of synaptic and neuronal pathways, while also providing a framework for molecular validation of dosage-sensitive phenotypes.

Ordered DNA Frameworks Improve Enzymatic DNA Synthesis
2026-08-29
The reference study introduces a tetrahedral DNA nanostructure interface that organizes primers for improved access by terminal deoxynucleotidyl transferase during enzymatic oligonucleotide synthesis. This architecture increased substrate affinity and reaction kinetics, reduced deletion errors, and supported synthesis of a 60-nucleotide information-storage sequence with a reported 96.82% stepwise yield.

Nonselective β-Blockade Impairs HCT Recovery
2026-08-27
The reference study shows that nonselective β-adrenergic receptor inhibitors can delay hematopoietic regeneration after allogeneic hematopoietic cell transplantation, whereas β1-selective inhibition has a less evident effect. By integrating mouse transplantation models with human cohort analyses, the work identifies β-blocker selectivity as a clinically relevant variable in post-transplant engraftment.
