• GLP-1 Receptor Promiscuity in FRET cAMP Assays

  2026-08-13

  Chepurny and colleagues used high-throughput FRET-based cAMP assays, pharmacological controls, and molecular modeling to show that glucagon can activate the GLP-1 receptor under appropriate experimental conditions. The findings challenge strict assumptions about peptide selectivity and provide a framework for interpreting antagonist studies, dual agonism, and triagonist design in metabolic research.

  2026-08-12

  KAS-ATAC combines ATAC-seq accessibility profiling with N3-kethoxal labeling of unpaired guanine residues to identify genomic fragments that are both physically accessible and single-stranded. The reference protocol provides a practical workflow for native-chromatin labeling, transposition, biotin enrichment, library preparation, and initial data processing.

• Red Blood Cell Lysis Buffer: Practical Workflow

  2026-08-12

  Build cleaner mammalian blood workflows by selectively removing erythrocytes before flow cytometry, nucleic acid extraction, protein analysis, or culture. This guide combines a practical erythrocyte lysis buffer workflow with assay-specific optimization and a careful translation of findings from osteoblast research.

• Melatonin, Autophagy, and Hypertrophic Scars

  2026-08-11

  A January 2024 study identifies MT2 receptor-dependent suppression of PI3K/Akt/mTOR signaling as a mechanism by which melatonin enhances autophagy and limits hypertrophic scar fibroblast activity. Evidence from primary human cells, transcriptomic analysis, pharmacological intervention, and a rabbit ear model supports autophagy as a potential antifibrotic target, while leaving important questions about clinical translation and direct oxidative-stress measurement.

• Crystal Violet Staining Solution: Signal to Biology

  2026-08-10

  Crystal Violet Staining Solution provides a practical endpoint for visualizing nuclei, adherent biomass, and colonies. This guide explains how to interpret its signal across mammalian cell assays and microbial biofilm studies without confusing staining intensity with viability.

• TBXA2R–ERM Signaling Drives TNBC Metastasis

  2026-08-09

  Leguay et al. identify TBXA2R as a GPCR that activates ERM proteins through Gαq/11, Gα12/13, Rho GTPases, and the kinases SLK and LOK. The resulting TBXA2R–ERM axis promotes triple-negative breast cancer cell motility, invasion, and metastatic colonization, providing a mechanistic framework for studying GPCR-controlled cytoskeletal remodeling.

• E-4031: hERG Potassium Channel Blocker

  2026-08-08

  E-4031 is a nanomolar hERG potassium channel blocker used in cardiac electrophysiology research. It suppresses the rapid delayed rectifier potassium current, prolongs repolarization, and supports controlled QT interval prolongation and torsades de pointes (TdP) induction studies.

• Berberine Hydrochloride: From AMPK to AKI Insight

  2026-08-07

  Berberine Hydrochloride is more than an AMPK-linked metabolic research reagent. This thought-leadership analysis connects its established roles in lipid metabolism modulation, LDL receptor upregulation, apoptosis, and ferroptosis with emerging AKI biology centered on oxidized self-DNA, cGAS-STING, NLRP3, A20, and NEK7—while clearly separating evidence from translational hypothesis.

• Cy7 NHS Ester: Protocol Guidance for Near-Infrared Protein L

  2026-08-07

  Cy7 NHS ester addresses the need for reliable, water-soluble, and low-quenching fluorescent labeling of proteins and peptides, especially for near-infrared imaging in live or sensitive systems. It is best suited for workflows requiring minimal organic co-solvents and robust signal retention. Researchers should avoid using it with targets incompatible with NHS chemistry or where long-term storage of labeling solutions is required.

• Primidone-Mediated TRPM3 Inhibition for Adenomyosis Manageme

  2026-08-06

  This study demonstrates that Primidone, an established antiepileptic, effectively inhibits TRPM3 channels to reduce pain and myometrial infiltration in adenomyosis models. These findings illuminate a novel therapeutic target and dosing strategy for conservative management of adenomyosis-associated pain.

• Moxidectin Potentiates Polyenes Against Candida via Ergoster

  2026-08-06

  This study reveals that moxidectin, a macrocyclic lactone anthelmintic, synergizes with polyene antifungals by inducing ergosterol biosynthesis in Candida albicans, thereby enhancing the efficacy of amphotericin B and nystatin. These findings suggest a promising new approach to overcoming antifungal resistance in oral candidiasis therapy.

• Gramine Induces Ferroptosis in TNBC via CUL3–MTDH Ubiquitina

  2026-08-05

  This study uncovers a novel mechanism by which gramine, a natural indole alkaloid, suppresses triple-negative breast cancer (TNBC) by inducing ferroptosis through modulation of the CUL3–MTDH ubiquitination axis. The findings offer new insights into ferroptosis regulation and highlight gramine’s therapeutic promise for aggressive breast cancer subtypes.

• ARCA EGFP mRNA: Reliable Reporter for Fluorescence Assays
