• AhR-Mediated MEHP Toxicity in Mouse Ovarian Follicles

  2026-08-31

  This study identifies the aryl hydrocarbon receptor as a functional mediator of mono(2-ethylhexyl) phthalate toxicity in mouse ovarian antral follicles. Pharmacological AhR blockade partially restored follicle growth and estrogen-related endpoints, linking phthalate exposure to altered xenobiotic signaling, steroidogenesis, and reproductive physiology.

• SIRT1–PGC-1α–TFAM Signaling in Prion-Stressed N2a Cells

  2026-08-31

  Zhao et al. show that prion protein fragment 106–126 damages mitochondria in N2a cells partly by suppressing SIRT1-dependent mitochondrial biogenesis. The study identifies the SIRT1–PGC-1α–TFAM axis as a mechanistic link between mitochondrial quality control and neuronal apoptosis, with resveratrol providing pharmacological support for this pathway.

• Canagliflozin Workflows for Renal Mitochondria

  2026-08-30

  Canagliflozin enables more than glucose-lowering experiments: it connects renal glucose transport with proximal-tubule mitochondrial structure, respiration, and albuminuria. This workflow guide shows how to build reproducible in vitro and in vivo studies while separating direct assay effects from secondary metabolic improvements.

• JXE-23 and Protective Autophagy in HCC

  2026-08-29

  A 2024 study identifies the fern-derived diterpene JXE-23 as a selective inhibitor of HepG2 hepatocellular carcinoma cell growth that produces G2/M arrest and suppresses migration. Its mechanistic contribution is the finding that JXE-23 induces protective, rather than decisively cytotoxic, autophagy through effects associated with the CIP2A/p-AKT/c-Myc axis.

• Temozolomide: A Genotype-Aware DNA Damage Tool

  2026-08-28

  Temozolomide is a small-molecule alkylating agent for modeling DNA damage, repair, and chemotherapy resistance. This article presents a genotype-aware assay framework based on ATRX-stratified glioma research, with practical guidance for interpreting combination responses.

• Omeprazole A2845: Gastric Acid Assay Workflow

  2026-08-28

  Omeprazole (SKU A2845) provides a research reagent for controlled H+,K+-ATPase inhibition and gastric acid secretion assays, with dossier-reported activity values and DMSO solubility guidance. It is intended for scientific research only and should not be used for diagnosis, treatment, or direct clinical conclusions.

• Exendin-4: From Mechanism to Translation

  2026-08-27

  Exendin-4, also known as Exenatide, connects GLP-1 receptor signaling with beta cell, metabolic, and manufacturing questions. This thought-leadership perspective shows how translational researchers can use cAMP biology, carefully staged phenotypic assays, and emerging yeast-expression strategies to strengthen type 2 diabetes research without overstating preclinical evidence.

• A20, Oxidized Self-DNA, and Acute Kidney Injury

  2026-08-27

  The reference study identifies oxidized self-DNA as an inflammatory driver in acute kidney injury and shows that A20 limits this response by suppressing STING signaling and NEK7-dependent NLRP3 pyroptosis. Its use of patient and mouse evidence, A20-derived peptide validation, and macrophage-specific NEK7 perturbation provides a mechanistic framework for therapeutic investigation.

• DPPH Antioxidant Screening: Workflow & Uses

  2026-08-26

  DPPH enables rapid, plate-compatible measurement of radical-scavenging activity in purified compounds, extracts, and discovery libraries. This workflow explains how to improve solvent compatibility, control optical interference, and pair the assay with chemical profiling for stronger natural-product decisions.

• Olive Biophenols and Alzheimer’s Pathology

  2026-08-26

  The reference study combines cell-based amyloid toxicity assays with an APPswe/PS1dE9 mouse model to evaluate olive biophenols as inhibitors of amyloid-related injury. Oleuropein, verbascoside, rutin, and an oleuropein-containing olive leaf extract reduced pathological readouts, while the authors emphasize that bioavailability, blood–brain barrier permeability, and mechanism require further validation.

• PF-562271 HCl for FAK/Pyk2 Cancer Assays

  2026-08-25

  PF-562271 HCl enables controlled dissection of FAK/Pyk2 signaling in adhesion, migration, proliferation, and tumor microenvironment assays. Its reversible, nanomolar activity is especially useful when paired with the reference study’s ERK-centered melanoma workflow to separate pathway effects from general cytotoxicity.

• Gemcitabine HCl in MRI-Guided Tumor Studies

  2026-08-25

  Pair Gemcitabine HCl’s mechanism-driven cytotoxicity with multianimal MRI to connect DNA replication inhibition, apoptosis induction in cancer cells, and longitudinal tumor measurements in pancreatic models. This workflow separates cell-line sensitivity from whole-tumor response while providing practical formulation, dosing, and troubleshooting guidance for reproducible preclinical studies.

• Anagliptin Vasorelaxation: Kv Channels and SERCA

  2026-08-24

  A 2025 Acta Diabetologica study shows that Anagliptin produces dose-dependent relaxation of phenylephrine-contracted rabbit aortic rings through voltage-dependent potassium channels and the SERCA pump. The response was independent of endothelium, cAMP/PKA signaling, cGMP/PKG signaling, and several other vascular potassium channel classes, providing a focused framework for vascular pharmacology research.

• Spartin-Mediated Lipid Transfer in Droplet Turnover

  2026-08-24

  This PNAS study identifies spartin as a lipid transfer protein in addition to its established role in directing lipid droplets toward autophagic degradation. By combining biochemical lipid-transfer assays with cellular turnover and localization analyses, the authors show that the spartin senescence domain is functionally required for lipid droplet degradation.

• PSPro Maps Cell-Type Proteomes in Tissue Space

  2026-08-23

  Mao et al. introduce PSPro, a proximity-labeling workflow that captures cell-type-associated proteomes directly from tissue slices with sub-micrometer spatial resolution. The method combines optimized antibody-targeted biotinylation, affinity purification, and optional laser microdissection to profile ten cell types and resolve proteome heterogeneity in pancreatic tumors and spleen.
