• Capsaicin: A Mechanism-First Assay Strategy

  2026-08-24

  Capsaicin is a powerful dual-purpose probe for TRPV1 signaling and KDM1A/LSD1 biology. This mechanism-first guide explains how to select concentrations, controls, and orthogonal readouts for pain, inflammation, neuronal, and gastric cancer research.

• APEX2 Promotes TERT Expression in Human Stem Cells

  2026-08-24

  The reference preprint identifies APEX2 as a DNA repair factor required for efficient TERT expression and telomerase activity in human embryonic stem cells. RNA-seq and chromatin immunoprecipitation connect this effect to APEX2 association with repeat-rich MIR sequences in the TERT locus, suggesting that local DNA repair can influence gene expression without direct promoter occupancy.

• CPI-613: From Metabolic Stress to Precision Oncology

  2026-08-23

  CPI-613 offers a mechanism-guided way to interrogate mitochondrial carbon metabolism, PDH/KGDH function, and apoptosis in cancer models. By connecting its bioenergetic effects with new evidence on PDHA1 acetylation, antioxidant defense, and cuproptosis in resistant prostate cancer, this article outlines a translational strategy for biomarker-led combination studies.

• hiPSC Intestinal Organoids for Pharmacokinetics

  2026-08-22

  Saito and colleagues established a direct three-dimensional culture strategy for generating expandable intestinal organoids from human induced pluripotent stem cells. The organoids could be cryopreserved, differentiated into intestinal epithelial monolayers, and evaluated for cytochrome P450 metabolism and transporter activity, supporting more human-relevant in vitro pharmacokinetic studies.

• Epalrestat for Polyol Pathway Research

  2026-08-21

  Epalrestat gives researchers a practical way to perturb aldose reductase activity while tracking polyol flux, oxidative stress, and downstream signaling. Its value extends from diabetic neuropathy research to exploratory fructose-metabolism studies in cancer and Parkinson’s disease model systems, provided the evidence boundaries are kept clear.

• Berberine, SIRT6-AMPK, and Atrial Fibrillation

  2026-08-20

  This study identifies impaired SIRT6-AMPK signaling as a mechanistic contributor to angiotensin II-induced atrial remodeling and shows that berberine limits atrial fibrillation susceptibility by suppressing NLRP3 inflammasome activation. Its combined use of human atrial samples, bioinformatics, pharmacological treatment, and SIRT6 gain- and loss-of-function experiments strengthens the proposed link between metabolic signaling, oxidative stress, inflammation, and arrhythmia.

• Isorhamnetin for Oocyte Stress & Signaling Research

  2026-08-20

  Isorhamnetin provides a chemically defined way to probe oxidative stress, apoptosis, endoplasmic reticulum stress, and PI3K/Akt-linked maturation in cultured oocytes. This workflow translates a concentration-defined reference study into practical dosing, controls, readouts, and troubleshooting decisions for reproductive and cellular stress research.

• EdU Cell Proliferation Kit for S-Phase Studies

  2026-08-19

  The EdU Cell Proliferation Kit (TMB) converts DNA synthesis into a quantitative, non-radioactive plate-reader signal for routine proliferation studies and translational drug testing. Its click-chemistry workflow is especially useful when researchers need direct S-phase evidence in rheumatoid arthritis fibroblast-like synoviocytes, while retaining a practical path to genotoxicity and pharmacodynamic experiments.

• Baicalein: Stress-Context Assays for 12-LOX

  2026-08-19

  Baicalein is a 12-LOX inhibitor suited to integrated studies of arachidonic acid metabolism, apoptosis, inflammation, and cancer biology. This article develops a stress-context assay strategy inspired by recent neurotoxicity research, while distinguishing demonstrated mechanisms from testable hypotheses.

• BIRB 796 (Doramapimod): Assay Guide

  2026-08-18

  This scenario-based guide explains how BIRB 796 (Doramapimod), SKU A5639, can help researchers interpret p38α MAPK-dependent viability, proliferation, apoptosis, and cytokine assays. It emphasizes solvent control, mechanistic readouts, dose optimization, and evidence-based product selection.

• PBS (Phosphate-Buffered Saline): Use Guide

  2026-08-18

  PBS (Phosphate-Buffered Saline), SKU K2818, provides a sterile, isotonic buffer for cell washing, reagent dilution, and other routine in vitro workflows requiring controlled pH and osmolarity. It is for scientific research use only, not for diagnostic or medical applications, and should not be treated as a nutrient-containing cell culture medium.

• Etoposide (VP-16): From DNA Breaks to Translation

  2026-08-17

  Etoposide (VP-16) is more than a cytotoxicity control: it is a mechanistic probe for topoisomerase II–associated DNA double-strand breaks, ATM signaling, homologous recombination, and apoptosis. This translational guide shows how to use the compound to connect DNA damage assays with biomarker and therapeutic-resistance hypotheses.

• TSPAN18–STIM1 Axis in Prostate Cancer Bone Metastasis

  2026-08-17

  Zhou et al. identified TSPAN18 as an upstream regulator of STIM1 stability in prostate cancer, showing that it protects STIM1 from TRIM32-mediated ubiquitination and degradation. The resulting increase in store-operated calcium entry promoted tumor-cell motility and bone metastasis, highlighting protein-stability control as a potential mechanistic entry point for prostate cancer research.

• Capsazepine: From TRPV1 Biology to Translation
