• Agatoxin-Sensitive Channels in Cardiac Vagal Neurons

  2026-09-27

  Wang, Irnaten, and Mendelowitz found that agatoxin-IVA-sensitive voltage-dependent calcium channels contribute to nicotine-evoked presynaptic and postsynaptic responses in cardiac vagal neurons. Their pharmacological experiments distinguish this channel contribution from effects of L-type channel blockade and provide a framework for separating synaptic release from postsynaptic current in calcium-channel studies.

• Niclosamide Workflows for STAT3 Cancer Research

  2026-09-26

  Build a more interpretable Niclosamide experiment by pairing STAT3 Tyr-705 measurements with separate apoptosis and cell-cycle readouts. This practical guide also shows how a snail-control study informs experimental design—not Niclosamide’s anticancer mechanism—and where that comparison stops.

• Machine Learning Prediction of mRNA Vaccine LNPs

  2026-09-25

  Wang and colleagues combined a LightGBM model, mouse testing, and molecular dynamics to explore prediction of mRNA vaccine lipid nanoparticle performance. Their results support machine learning as a way to prioritize formulations for experimental testing, while also showing why predictions must be interpreted within the limits of the training data and assay endpoints.

• GluN2B R519Q Is Cleared Through Autophagy

  2026-09-25

  The bioRxiv study reports that the disease-associated GluN2B R519Q variant is retained in the endoplasmic reticulum, fails to reach the cell surface, and is cleared through autophagy-lysosomal pathways. By combining pathway inhibition with tests of an LC3-interacting region and ER-phagy receptors, the authors provide a mechanistic framework for investigating how mistrafficked NMDA receptor subunits are removed.

• Vagal Heart–Insula Signaling in PTSD Mice

  2026-09-24

  A mouse study links heightened cardiac activity to insular cortex hyperactivity and PTSD-like behaviors, with cervical vagotomy interrupting effects induced by chronic isoproterenol. Propranolol reduced cardiac, neural, and behavioral abnormalities in the stress model, offering a mechanistic framework for studying heart–brain interactions while leaving important questions about pathway direction and human relevance unresolved.

• SELENOK–CD36 Palmitoylation in Microglial Aβ Clearance

  2026-09-24

  The study links selenium biology to Alzheimer’s disease pathology by showing that SELENOK supports DHHC6-associated CD36 palmitoylation, microglial function, and amyloid-beta phagocytosis. Its findings position this pathway as a mechanistic candidate for further investigation, while leaving important questions about assay details, cell-specific effects, and therapeutic translation unresolved.

• Uremic Toxins Reshape Protein Adsorption on mPEO

  2026-09-23

  This study examines how uremic metabolites alter plasma-protein adsorption on methoxy-terminated polyethylene oxide (mPEO) films with different chain densities. Its central finding—that toxins increase adsorption of nearly all assessed proteins—shows why low-fouling biomaterials should be evaluated in disease-relevant blood environments, not only with healthy-donor samples.

• GlycoRNA–RBP Nanodomains Drive Peptide Entry

  2026-09-23

  This preprint reports that cell-surface RNA-binding proteins and glycoRNAs organize into extracellular nanoclusters that support entry of the cell-penetrating peptide TAT. Its perturbation-based evidence expands the cell-surface model beyond transmembrane proteins and suggests that RNA-dependent domains can regulate cell–environment communication and peptide internalization.

• Estradiol Benzoate: ERα Assay Workflows

  2026-09-22

  Build more reproducible estrogen receptor experiments with a high-purity synthetic estradiol analog, from stock preparation through binding and cell-based signaling assays. Practical concentration ranges, solvent controls, and troubleshooting guidance help distinguish true estrogen receptor activity from formulation and assay artifacts.

• Sulfo-NHS-Biotin for Single-Cell Assays

  2026-09-22

  Sulfo-NHS-Biotin combines aqueous compatibility with covalent amine labeling, making it useful for cell-surface phenotyping, protein capture, and interaction assays. When paired conceptually with capped nanovials, it can help connect molecular labeling readouts with scalable single-cell growth, secretion, and co-culture workflows.

• HyperScript III RT SuperMix for CRC qPCR

  2026-09-21

  Translate bile acid metabolism signatures into reproducible CRC biomarker assays with high-yield cDNA synthesis, genomic DNA contamination removal, and support for low-input or high-GC RNA. This workflow shows how to validate CLCA1, UGT2A3, and ZG16 by two-step qRT-PCR without treating computational associations as clinical proof.

• Sulfo-NHS-SS-Biotin for Dynamic Surface Mapping

  2026-09-21

  Sulfo-NHS-SS-Biotin enables water-compatible, reversible labeling of surface-accessible proteins. This article explains how its cleavable chemistry can sharpen assay design for cell-surface organization, protein capture, and glycoRNA–RBP research.

• Reversible Surface Labeling for Translational Insight

  2026-09-20

  Cell-surface biology is moving beyond a catalog of transmembrane proteins toward dynamic domains containing proteins, glycoRNAs, and regulatory interactions. This thought-leadership article explains how Sulfo-NHS-SS-Biotin can help translational researchers distinguish surface accessibility, interaction stability, and reversible molecular capture while highlighting the evidence boundaries of emerging glycoRNA–RNA-binding protein research.

• Sulfo-NHS-LC-Biotin: Practical Labeling Guide

  2026-09-19

  Sulfo-NHS-LC-Biotin is a water-compatible reagent for covalently labeling primary amines on proteins, peptides, and accessible cell-surface proteins for downstream capture or detection. It is appropriate for stable extracellular or soluble-protein labeling, but not for intracellular labeling in intact cells or workflows requiring reversible biotin removal.

• Peptidisc-Assisted Nanobody Polybody Engineering

  2026-09-18

  A 2025 bioRxiv preprint introduces peptidisc-assisted hydrophobic clustering as a strategy for assembling nanobodies into soluble multimeric, bispecific, and autofluorescent polybodies. The approach uses transmembrane-segment-driven association and peptidisc stabilization to improve avidity while expanding the design space beyond tandem linking and conventional oligomerization scaffolds.
