• MVC Activates RhoA/ROCK1 to Disrupt Tight Junctions

  2026-09-05

  The reference study identifies a mechanism by which Minute Virus of Canines (MVC) activates the RhoA/ROCK1/MLC2 axis, remodels tight junctions, and promotes occludin-associated viral entry. Its combination of VP2–ROCK1 interaction mapping, pathway inhibition, permeability analysis, and viral replication readouts provides a mechanistic framework for studying MVC infection in canine cells.

• GPR35–KLF5 Repair Circuitry in Colitis

  2026-09-04

  A 2026 Cell Death & Disease study identifies a tryptophan–kynurenine–kynurenic acid sensing mechanism in which GPR35 activates KLF5-dependent epithelial repair through PI3K–AKT–mTOR signaling.

  2026-09-02

  Promethazine HCl supports controlled studies of H1 receptor antagonism, macrophage ROS, autophagy, and host-directed antibacterial activity. This practical guide connects assay design with concentration planning, mechanistic controls, and troubleshooting while separating evidence from workflow recommendations.

• PreScission Protease (PSP): Practical Tag Cleavage

  2026-09-02

  PreScission Protease (PSP) provides sequence-specific removal of compatible fusion tags from recombinant proteins through HRV 3C protease cleavage at the Gln-Gly junction. It is suited to controlled protein purification workflows operated at low temperature, but should not be treated as a universal protease for constructs lacking the recognition site or for conditions that have not been validated.

• Inside-Out Design of Ternary RNA Nanoparticles

  2026-09-01

  This ACS Nano study shows that polyanion chemistry, PEG architecture, hydrophobicity, and charge density jointly determine the structure and biological performance of ternary nanoparticles for self-amplifying RNA delivery. By combining high-throughput stability assays, neutron scattering, spectroscopy, cell studies, and molecular dynamics, the authors identify a pH-responsive formulation that balances extracellular stability with intracellular RNA release.

• H 89 2HCl for Reproducible PKA Assays

  2026-09-01

  A scenario-based guide to using H 89 2HCl (SKU B2190) in cell viability, proliferation, and cytotoxicity workflows. It explains solvent handling, concentration selection, pathway-specific controls, off-target interpretation, and practical criteria for choosing a reliable PKA inhibitor.

• Azumiobodo hoyamushi Drug Efficacy in Ascidians

  2026-08-31

  Park and colleagues combined an in vitro concentration-response screen with an in vivo infection model to evaluate control strategies for Azumiobodo hoyamushi, the protozoan associated with soft tunic syndrome in cultured ascidians. The study identified formalin and chlorine dioxide as the most promising agents for reducing parasite burden in infected Halocynthia roretzi, while Sulfamonomethoxine showed comparatively weak direct antiparasitic activity under the tested conditions.

• Fulvestrant: ER Causal Inference in Cancer Models

  2026-08-31

  Fulvestrant (ICI 182,780) is more than an estrogen antagonist: it is a practical probe for separating ER-dependent signaling, MDM2 protein degradation, and downstream cell fate.
