• How Fasting Reprograms Translation and Tumor Growth

  2026-09-01

  Yang et al. identify a fasting-responsive AMPK–MNK–eIF4E pathway that selectively remodels liver translation even as global protein synthesis declines. The study links this translational program to ketogenesis and shows that combining a ketogenic diet with P-eIF4E inhibition can restrain pancreatic tumor growth in a preclinical model.

• 5X Protein Loading Buffer (Reducing) Guide

  2026-08-31

  5X Protein Loading Buffer (Reducing) standardizes denaturing and reducing protein sample preparation before conventional SDS-PAGE electrophoresis. It is intended for protein molecular weight separation under reducing conditions and should not be used for native, non-reducing, or disulfide-dependent structure analyses.

• Adipose–Neural Signaling in Cardiac Arrhythmias

  2026-08-31

  Fan et al. developed a stem cell-based coculture model showing that epicardial adipose tissue can promote arrhythmogenic activity through a leptin–sympathetic neuron–NPY pathway involving Y1R, NCX, and CaMKII. The study links this experimental mechanism to atrial fibrillation-associated increases in epicardial adipose tissue thickness and coronary sinus leptin and NPY levels, while also defining important boundaries for applying Y2 receptor tools to follow-up research.

• Brassinolide Workflows for Plant and Cancer Research

  2026-08-30

  Brassinolide, also indexed as 24-Epibrassinolide, connects precision plant-growth assays with apoptosis, cancer, and metabolic disease models. This practical guide translates recent root-growth findings into controlled workflows, solvent strategies, assay controls, and troubleshooting decisions.

• Neuromedin S (rat): Practical GPCR Assay Guide

  2026-08-29

  Neuromedin S (rat) provides a chemically defined peptide input for controlled neuromedin U receptor signaling and GPCR/G protein signaling workflows. It is suitable for rat-relevant research assays, but should not be used as evidence of potency, cross-species activity, diagnostic utility, or therapeutic effect without additional validation.

• Z-DEVD-FMK: Caspase-3 Inhibitor Workflows

  2026-08-29

  Z-DEVD-FMK combines cell permeability and irreversible caspase inhibition with measurable calpain-pathway effects, making it useful for apoptosis assays, neuronal injury models, and mechanistic infection studies. This workflow-focused guide shows how to separate caspase-3-dependent rescue from broader changes in cell death and innate immune signaling.

• Mtb–BMX Signaling Controls Lysosomal Acidification

  2026-08-28

  The reference study identifies a host-pathogen mechanism in which Mycobacterium tuberculosis Chp2/Rv1184 redirects BMX-dependent phosphorylation of ATP6V1E1, weakening V-ATPase assembly and lysosomal acidification. By connecting this pathway to intracellular bacterial growth in macrophages and mice, the work positions BMX and lysosomal proton-pump regulation as potential targets for host-directed tuberculosis research.

• Methylprednisolone: From GR Signal to Bone Loss

  2026-08-28

  Methylprednisolone is more than an anti-inflammatory reagent: it can serve as a controlled glucocorticoid challenge for connecting cytokine suppression with osteoclast-driven tissue injury. This article translates recent glucocorticoid-induced osteonecrosis evidence into practical assay design, model selection, and translational decision-making.

• Chaperone-Mediated Autophagy and Muscle Aging

  2026-08-27

  The reference study identifies chaperone-mediated autophagy (CMA) as an active regulator of skeletal muscle integrity rather than a passive housekeeping pathway. Using reporter, genetic, proteomic, calcium-imaging, human-tissue, and rescue experiments, the authors connect age-related CMA decline to impaired SERCA turnover, abnormal calcium handling, and progressive myopathy.

• CAY10499: Inhibitor of Human Hormone Sensitive Lipase

  2026-08-27

  CAY10499 enables controlled interrogation of HSL, MGL, FAAH, and lipid-transmitter turnover across enzyme, macrophage, and metabolic disease models. This practical guide connects its use as a lipid metabolism assay reagent to EV-driven tumor-associated macrophage research while clearly separating established product data from testable workflow hypotheses.

• PX-478 2HCl: Reliable Hypoxia Assays

  2026-08-26

  Learn how PX-478 2HCl, SKU B6004, can improve the interpretation of viability, proliferation, and hypoxia-response assays. This scenario-based guide covers concentration selection, solvent controls, hypoxia workflows, radiosensitization studies, and practical product evaluation.

• Clozapine N-oxide (CNO) Chemogenetics Workflow

  2026-08-26

  Clozapine N-oxide (CNO) enables reversible, receptor-selective control of defined neuronal populations, making it useful for causal circuit studies rather than descriptive pharmacology alone. This workflow connects DREADD validation with behavioral testing, 24-hour EEG, and troubleshooting strategies for cleaner neuroscience research.

• Bismuth Subsalicylate in GI Inflammation Workflows

  2026-08-25

  Build more interpretable gastrointestinal disorder research workflows with Bismuth Subsalicylate, combining inflammation-pathway readouts with formulation controls and annexin V-based viability checks. This practical framework separates apparent anti-inflammatory activity from precipitation artifacts, membrane injury, and apoptosis-related signal changes.

• AMPK–JAK2/STAT3 Signaling in Obesity-Related Asthma

  2026-08-25

  The reference study identifies reduced AMPK activity and M1 macrophage polarization as linked features of obesity-related asthma, and positions the JAK2/STAT3 axis as a mechanistic connection between them. By combining mouse models with LPS-stimulated RAW264.7 macrophages, the work shows that AMPK activation can reduce inflammatory polarization and airway inflammation, providing a framework for testing pathway dependence.

• Diclofenac in Intestinal Organoid Research

  2026-08-24

  Use Diclofenac as a non-selective COX inhibitor to connect prostaglandin biology with human intestinal absorption, metabolism, and barrier studies. This workflow combines controlled COX modulation with hiPSC-derived intestinal organoids, offering a more translational complement to conventional cell-line assays.
