BMP4-GPX4 Protects RGCs in NMDA Glaucoma Models
2026-09-19
The reference study identifies a BMP4–GPX4 pathway that links ferroptosis control with retinal ganglion cell survival and retinal stem cell differentiation in an NMDA-induced glaucoma model. Its findings support a mechanistic framework for improving transplantation outcomes, while also highlighting the limits of extrapolating an excitotoxic mouse model to chronic human glaucoma.

PPARγ, Macrophage Polarization, and DSS Colitis
2026-09-18
The reference study links PPARγ activation to improved DSS-induced colitis through coordinated changes in macrophage polarization and STAT-1/STAT-6 signaling. Its combined cell and mouse models provide a mechanistic framework for interpreting intestinal barrier repair, while also defining important limits for extrapolation to other PPARγ-associated disease areas.

ISR and Accelerated Forgetting in Epilepsy
2026-09-18
A 2025 Molecular Neurobiology study identifies integrated stress response activation as a molecular correlate of both natural forgetting and seizure-associated accelerated forgetting in mice. Its retention-interval experiments show that repeated ISRIB treatment can preserve established recognition memories, while a single administration does not alter retrieval, offering a mechanistic framework for studying maladaptive memory loss.

Mitoxantrone Assays: Workflow, Resistance & Optimization
2026-09-17
Build more informative Mitoxantrone experiments by separating topoisomerase II activity, apoptosis, intracellular exposure, and ABCG2-mediated resistance. This workflow also shows how to translate the marein–ABCG2 findings into practical combination and transporter assays without confusing chemosensitization with direct cytotoxicity.

Bufalin–STK33 Targeting in Triple-Negative Breast Cancer
2026-09-17
The 2025 Advanced Science study identifies serine/threonine kinase 33 (STK33) as a direct binding and degradation target of Bufalin in triple-negative breast cancer. By combining target discovery, binding validation, genetic perturbation, animal models, and patient-derived organoids, the work connects Bufalin exposure to disruption of the STK33–HSP90 complex and suppression of tumor-cell proliferation.

Berberrubine and the Vitamin K Cycle in Thrombosis
2026-09-16
The reference study integrates mouse thrombosis pharmacology, non-targeted metabolomics, and molecular docking to connect berberrubine with the vitamin K catalytic cycle. Its most important finding is a separation between prolonged prothrombin time and the absence of increased bleeding time, offering a mechanistic basis for further evaluation of this natural-product metabolite as an antithrombotic lead.

Tricine-SDS-PAGE Gel Preparation Kit Protocol
2026-09-15
The Tricine-SDS-PAGE Electrophoresis System Gel Preparation Kit is designed for higher-resolution protein electrophoresis and peptide separation in the low-molecular-weight range, including targets from 1 to 10 kDa. It is intended for research workflows, not diagnostic or medical use, and should be validated with the laboratory’s own samples, markers, and running conditions.

Proteoform-Specific Drug Interactions in Native Membranes
2026-09-15
The reference study establishes a native mass spectrometry workflow for connecting membrane-protein post-translational modifications with ligand binding and complex assembly. Using retinal rod disc membranes, it resolves rhodopsin and G-protein proteoforms and reveals differential off-target recognition of PDE6 by sildenafil and vardenafil, offering a more precise framework for drug selectivity studies.

Cabazitaxel (XRP6258): Workflow and QC Guide
2026-09-14
Cabazitaxel (XRP6258, SKU B2157) provides a practical research option for antiproliferative assays involving taxane-resistant or P-glycoprotein-expressing cancer cell lines. It is suitable for DMSO- or ethanol-based workflows, but not for direct aqueous preparation or long-term storage of solutions.

ARID1A Loss and Osimertinib Resistance in Lung Cancer
2026-09-14
This study identifies an ARID1A–PTEN–Akt signaling axis that links chromatin regulation to acquired osimertinib resistance in lung adenocarcinoma models. Its combination of genetic perturbation, drug-response assays, phenotypic measurements, immunoblotting, and CUT&Tag supports PTEN transcriptional control as a mechanistic explanation and a potential basis for combination treatment strategies.

Clathrin-Mediated Entry of Grass Carp Reovirus
2026-09-13
Wang et al. used pharmacological inhibitors, transmission electron microscopy, and quantitative PCR to show that genotype III grass carp reovirus enters CIK cells through dynamin-dependent, clathrin-mediated endocytosis requiring endosomal acidification. The lack of inhibition by Latrunculin B under the tested conditions provides a useful negative control for interpreting actin cytoskeleton disruption during viral-entry studies.

MEK–ERK Signaling in Lupus Lung Hemorrhage
2026-09-12
This preprint identifies MEK1/2–ERK1/2 activation as a pharmacologically targetable driver of endothelial injury, altered hemostasis, and diffuse alveolar hemorrhage in pristane-induced lupus in susceptible B6 mice. Its inhibitor-comparison design separates the MEK–ERK axis from JNK and p38 signaling and connects pathway activity with apoptosis, Egr1 expression, tissue-factor regulation, and bleeding phenotypes.

Substrate Stiffness Drives Dentinogenesis via FAK
2026-09-11
Bai and colleagues show that substrate stiffness regulates odontoblast-like cell behavior and dentinogenic differentiation through a LAMB1–FAK–MEK1/2 signaling axis. The work links material mechanics to focal-adhesion signaling and provides a mechanistic framework for designing dental biomaterials that support reparative dentin formation.
