• Protease Inhibitor Cocktail (EDTA-Free, 100X in DMSO)

  2026-09-09

  Protease Inhibitor Cocktail (EDTA-Free, 100X in DMSO) helps limit endogenous proteolysis during protein extraction and sample preparation without introducing EDTA into cation-sensitive workflows. It is appropriate for applications such as Western blotting, co-immunoprecipitation, pull-down assays, phosphorylation analysis, and kinase assays, but it should not be treated as a substitute for metalloprotease or phosphatase inhibition when those activities must be controlled.

• SP600125 for Nanoplastic Vascular Signaling

  2026-09-09

  Explore how SP600125, a selective JNK inhibitor, can test whether JNK contributes to nanoplastic-induced vascular lipid dysregulation beyond the established ERK/UHRF1 axis. This evidence-aware workflow connects developmental cardiovascular toxicology with rigorous pathway-dissection strategies.

• Astrocytic GAT-3 Controls Dentate Gyrus Memory

  2026-09-08

  The reference study shows that astrocytic GAT-3 is an active signaling mechanism in the entorhinal cortex–dentate gyrus circuit, not merely a transporter that clears GABA. By linking GAT-3-dependent astrocyte calcium signaling to presynaptic GluN2B-containing NMDARs and contextual fear memory, it provides a mechanistic framework for studying glia-mediated synaptic plasticity.

• Ademetionine in Neurological Disorders: Evidence and Limits

  2026-09-08

  Bottiglieri, Hyland, and Reynolds presented an integrative review linking central nervous system methylation, folate and vitamin B12 metabolism, monoamine signaling, and neurological disease. Its practical value lies in showing why ademetionine may be relevant across depression, dementia, demyelinating disease, and metabolic disorders while emphasizing that the clinical evidence was preliminary and heterogeneous.

• Everolimus (RAD001): From Arrest to Cell Death

  2026-09-07

  Everolimus (RAD001) is an mTOR pathway inhibitor whose apparent viability effects can reflect growth arrest, cell killing, or both. This guide applies a time-resolved framework to improve cancer assay interpretation and translational relevance.

• Aminopeptidase Selectivity and ACE Inhibitor Action

  2026-09-07

  The 1992 study directly compared metallopeptidase inhibitors against cell-surface aminopeptidases A, N, and W, revealing that inhibitor behavior differed substantially across closely related enzymes. Its findings caution against inferring aminopeptidase selectivity from ACE inhibitor activity alone and provide a framework for designing more discriminating biochemical assays.

• Astrocytic GAT-3 in Dentate Gyrus Memory

  2026-09-05

  The reference study identifies astrocytic GAT-3 as an active signaling component in the entorhinal cortex–dentate gyrus circuit, rather than only a GABA clearance transporter. Its electrophysiological, optogenetic, calcium, and behavioral evidence connects GAT-3 activity to astrocytic Ca2+ signaling, presynaptic GluN2B-containing NMDA receptors, enhanced excitatory transmission, and contextual fear-memory formation.

• HIV-1, Nuclear Pores, and Resting T Cells

  2026-09-04

  The reference study identifies nuclear pore complex remodeling as a major bottleneck limiting HIV-1 infection of resting CD4+ T cells. It shows that cell–cell spread activates CD4–LCK–CDK1 signaling, phosphorylates nucleoporins without requiring cell-cycle entry, and enables viral capsid nuclear import.

• Cell Integrity Limits Ploidy in Budding Yeast

  2026-09-04

  The reference study defines a physiological ceiling for genome amplification in budding yeast and links that ceiling to cell size and surface stress rather than chromosome content alone. Its experimental framework provides a useful basis for interpreting membrane-integrity phenotypes, while also showing why drug-related conclusions require separate validation.

• Cisapride in Predictive Cardiac Assays

  2026-09-03

  Cisapride (R 51619) connects 5-HT4 receptor pharmacology with hERG-mediated cardiac risk. This article presents an assay-decision framework combining orthogonal electrophysiology, iPSC-cardiomyocytes, and deep-learning phenotyping.

• Mouse Tissue Lysis Kit (K1038): Practical Workflow

  2026-09-03

  The Mouse Tissue Lysis Kit (K1038) prepares mouse tissue lysates for direct PCR-based genotyping without a separate DNA extraction or purification step. It is intended for molecular biology research and should not be used for diagnostic, clinical, or medical applications.

• CGP 55845 Hydrochloride in Synaptic Assays

  2026-09-02

  CGP 55845 hydrochloride is a selective GABAB receptor antagonist for separating receptor-driven inhibition from astrocyte-mediated signaling. This article develops an assay framework linking presynaptic release, astrocytic calcium activity, and dentate gyrus synaptic physiology.

• GSK621 AMPK Agonist: Assays and Workflows

  2026-09-02

  GSK621 is a potent AMPK agonist for connecting energy sensing with AML cell fate, lipid metabolism, autophagy, and immune-cell reprogramming. This practical guide covers solvent handling, phospho-AMPK assay design, macrophage applications, comparative controls, and troubleshooting.

• Self-Activatable Nanozymes Potentiate CRC Immunotherapy

  2026-09-01

  This ACS Nano study develops AS@PMFM, a macrophage-targeted, hydrogen peroxide-activated polymeric nanozyme that combines ferrocene chemistry with artesunate to eliminate intracellular Fusobacterium nucleatum in colorectal cancer. By clearing bacterial reservoirs and reprogramming macrophage activity, the platform substantially improves the response to CD47 blockade in cellular and mouse CRC models.

• Astrocyte Heterogeneity Across Space and Time

  2026-09-01

  Schroeder et al. present a cross-species single-nucleus transcriptomic atlas showing that astrocyte regional identity is established early but is substantially remodeled after birth. The study combines molecular profiling across brain regions and developmental stages with expansion microscopy, providing a framework for linking astrocyte gene programs to regional morphology and circuit context.
