  Use Methotrexate as a mechanistic probe for DHFR inhibition, activated T-cell apoptosis, proliferation control, and immunosuppression. Pair cell-based experiments with IAM-LC or OT-CEC-MS to distinguish membrane interaction, intracellular persistence, and biological response.

• L. plantarum P101, AMPK, and Alcoholic Fatty Liver

  2026-08-20

  This 2025 study shows that Lactiplantibacillus plantarum P101 reduced alcohol-induced hepatic lipid accumulation in mice, with evidence that AMPK activation was required for the protective phenotype. By combining pharmacological pathway inhibition with gut microbiota profiling and serum metabolomics, the work connects probiotic intervention to a gut–liver metabolic mechanism while identifying candidate microbial and metabolite correlates.

• Dronedarone: Reading the KCa2 Assay Correctly

  2026-08-19

  Dronedarone (Multaq) is more than a broad antiarrhythmic comparator: its behavior in KCa2 channel assays helps researchers separate multi-ion-channel effects from atrial-selective mechanisms.

• Clarithromycin as a CYP3A Inhibitor

  2026-08-18

  Use Clarithromycin as a controlled CYP3A perturbation tool for enzyme assays, pharmacokinetic studies, and statin metabolism interaction experiments. This workflow pairs concentration-resolved inhibition with a CYP-independent comparator to separate pathway effects from broader changes in drug disposition.

• NADPH Oxidase ROS Activate L-Type Ca2+ Channels

  2026-08-18

  This study identifies L-type voltage-gated Ca2+ channels as the principal downstream route by which NADPH oxidase-derived ROS promote arterial contraction in early postnatal rats. Pharmacological comparisons show that Rho-kinase, PKC, and Src-kinase contribute to methoxamine contraction but are not required for the specific procontractile effect of NADPH oxidase-derived ROS.
