• RAB31 and ESCRT-Independent Exosome Biogenesis

  2026-09-09

  The reference study identifies RAB31 as a regulator that both drives intraluminal vesicle formation and prevents multivesicular endosome degradation. Its findings connect EGFR phosphorylation, flotillin lipid-raft domains, and TBC1D2B-mediated RAB7 inactivation into an ESCRT-independent exosome pathway with important implications for membrane trafficking research.

  2026-09-08

  Topotecan, also known as SKF104864, is examined here through a pharmacology-to-assay framework that connects lactone chemistry, replication-fork damage, exposure scheduling, and translational interpretation. The article provides a distinct strategy for using this topoisomerase I inhibitor in cancer research, including glioma and pediatric tumor models.

• Concanavalin A and Conserved Coronavirus N-Glycans

  2026-09-07

  Guo and colleagues identify conserved high-mannose N-glycosylation sites near the coronavirus spike S2′ cleavage region as a broad-spectrum antiviral vulnerability. Using fusion, pseudovirus, authentic-virus, biochemical, and animal models, the study shows that concanavalin A blocks spike activation and reduces hCoV-NL63 disease in vivo, while also defining important limits for translation.

• REV1–DHX36 Coordinates G-Quadruplex Tolerance

  2026-09-07

  Ketkar and colleagues identify a direct REV1–DHX36 interaction that couples G-quadruplex unwinding with suppression of single-stranded DNA gaps during replication. The study shows that REV1 loss redirects fork progression toward PrimPol-dependent synthesis, elevates DNA damage signaling, and increases sensitivity to G-quadruplex stabilization, providing a mechanistic framework for genome-integrity research.

• AO/PI Double Staining Kit for Glioma Organoids

  2026-09-03

  Learn how the AO/PI Double Staining Kit can support cell viability assay design in patient-derived glioma organoids. This guide connects Acridine Orange Propidium Iodide staining with microenvironment preservation, spatial interpretation, and better drug-screening decisions.

• circRHOBTB3 and Metastatic Prostate Cancer

  2026-09-03

  A 2025 Cancer Letters study identifies circRHOBTB3 as a suppressive circular RNA that limits prostate cancer proliferation and metastasis by retaining NONO in the cytoplasm and reducing MAOA transcription. The work also connects circRNA function with biogenesis by showing that SRSF9 binding to Alu elements inhibits circRHOBTB3 circularization, providing a mechanistic framework for biomarker and therapeutic research.

• PYR-41 Workflows for E1 and IRF7 Assays

  2026-09-02

  Build mechanism-focused assays around PYR-41 to connect ubiquitin activation, protein stability, NF-κB signaling, and antiviral responses. This guide emphasizes staged dosing, orthogonal controls, and careful interpretation across cell-based and preclinical inflammation models.

• Phosbind Acrylamide: Practical SDS-PAGE Guide

  2026-09-02

  Phosbind Acrylamide is a MnCl2-containing phosphate-binding reagent for resolving phosphorylation-dependent mobility changes during SDS-PAGE, reducing reliance on phospho-specific antibodies for an initial screen. It is most appropriate for protein targets in the 30–130 kDa range and should not be treated as a site-mapping, stoichiometry, or pathway-causality assay.

• ARCA EGFP mRNA: A Translational Control Strategy
