• Glucocorticoids, Kv2.1, and CaV1.2 in Neurons

  2026-08-18

  The reference study identifies a rapid, non-genomic pathway by which glucocorticoids suppress CaV1.2-mediated calcium signals in hippocampal neurons. Its central advance is linking reduced cAMP–PKA activity to endocytosis of Kv2.1 channel clusters, which secondarily drives the removal of associated CaV1.2 channels from the cell surface.

• PPZ1–TORC1 Drives Ferroptosis in C. albicans

  2026-08-18

  The reference study identifies the fungus-specific phosphatase PPZ1 and TORC1 signaling as regulators of tert-butyl hydroperoxide-induced ferroptosis in Candida albicans. Its findings connect ferroptotic sensitivity, autophagy, and antifungal resistance, suggesting that fungal ferroptosis could complement conventional drug strategies while highlighting important species-specific limitations.

• PreScission Protease (PSP) Tag Cleavage Guide

  2026-08-17

  PreScission Protease (PSP), SKU K1101, enables sequence-specific removal of compatible affinity tags from recombinant fusion proteins at low temperature. It is intended for constructs containing the LEVLFQGP recognition site and should not be treated as a universal protease for proteins lacking an accessible site or for workflows without construct-specific validation.

• CD44 Metabolic Rewiring in IDH-Mutant Leukemia

  2026-08-17

  The reference study identifies CD44 as a metabolic dependency in IDH-mutant leukemia, linking R-2HG-driven signaling to pentose phosphate pathway activity, NADPH production, and continued oncometabolite synthesis. Its isogenic CRISPR-based design supports a model in which combined IDH and CD44 targeting may improve elimination of leukemia cells beyond IDH inhibition alone.

• Annexin V-Cy5 Apoptosis Kit for Microglia Studies

  2026-08-16

  The Annexin V-Cy5 Apoptosis Kit provides a rapid way to separate phosphatidylserine-positive cell death from the lysosomal stress phenotype reported in zebrafish microglia. Its 10-minute staining workflow supports both flow cytometry apoptosis detection and fluorescence microscopy apoptosis analysis, making it useful for exposure, washout, and cell-type-specific experiments. APExBIO supplies the kit for research use only.

• Foxp1–Notch Control of CKD Valvular Calcification

  2026-08-15

  A 2026 Biochemical Pharmacology study identifies endothelial Foxp1 as a regulator of chronic kidney disease-associated valvular calcification. Using endothelial-specific Foxp1 overexpression and complementary cellular assays, the authors connect Foxp1 repression of Jagged-1/Notch signaling with reduced endothelial-to-mesenchymal transition, lower TGF-β1 signaling, and weaker osteogenic activation of valvular interstitial cells.

• Nigericin Workflows for pH and Ion-Gradient Assays

  2026-08-14

  Nigericin enables controlled perturbation of potassium–proton exchange, intracellular pH, and mitochondrial ion gradients in oncology, metabolic, and antimicrobial research. This practical guide combines fresh-solution handling, assay controls, dose-screening logic, and a cautious extension of NADH–antibiotic findings into ion-gradient studies.

• Astrocyte–Microglia Crosstalk in CNS Repair

  2026-08-14

  Cao and colleagues identify a reciprocal CSF1–IFN-β signaling circuit between lesion-border astrocytes and microglia that supports spinal cord wound closure and motor recovery. The study links astrocyte-derived CSF1 to microglial proliferation and microglial IFN-β to astrocyte survival, providing a mechanistic framework for interpreting glial cooperation after CNS injury.

• v-Agatoxin-IVA Reveals N-Type Channel Blockade

  2026-08-13

  Sidach and Mintz showed that v-Agatoxin-IVA is highly selective for P-type calcium channels at high affinity but can also produce weaker, voltage-dependent blockade of N-type and Q-like currents at micromolar concentrations. Their whole-cell recordings refine pharmacological criteria for classifying neuronal calcium channels and caution against using toxin sensitivity alone to identify Q-type currents.

• Pexmetinib (ARRY-614) and p38 Signaling

  2026-08-13

  Pexmetinib (ARRY-614) offers a research platform for connecting p38 MAPK and Tie2 biology with cytokine control, bone marrow signaling, and translational assay design. New structural work on p38α dephosphorylation adds a compelling framework for evaluating kinase inhibitors beyond simple active-site blockade.

• Gamithromycin: Tissue-Site PK/PD Guide

  2026-08-12

  Gamithromycin is best interpreted through tissue distribution, cellular accumulation, and pathogen-specific PK/PD rather than plasma levels alone. This evidence-led guide translates pulmonary pharmacology into more rigorous veterinary respiratory infection assays.

• Vernakalant Hydrochloride: From Channels to Conversion

  2026-08-12

  Vernakalant Hydrochloride, also known as RSD1235, is examined through a translational lens linking ion-channel pharmacology, exposure, and rapid atrial fibrillation conversion. This article shows how to convert mechanistic and clinical evidence into better assay design and more defensible experimental interpretation.

• Annexin V-Cy5 Apoptosis Kit in Microglia

  2026-08-11

  Mestranol-treated zebrafish microglia reveal why lysosomal stress should not be equated with apoptosis. This thought-leadership article explains how Annexin V-Cy5 Apoptosis Kit-based Annexin V apoptosis detection can add a mechanistically distinct endpoint to neuroimmunotoxicity and translational lysosomal-stress studies.

• KN-62 Workflows for CaMKII Signaling Studies

  2026-08-11

  KN-62 enables controlled interrogation of CaMKII-dependent calcium signaling across secretion, metabolism, cell-cycle, and exploratory synaptic assays. This practical guide connects concentration planning, assay controls, and troubleshooting with the neuroligin-1 mechanism reported in recent social-memory research.

• Caged Bioluminescent Probes for Immunoproteasome

  2026-08-10

  Loy and Trader describe a cleavable, peptide-based bioluminescent probe designed to report immunoproteasome activity, with selectivity for the β5i catalytic subunit. The protocol links probe synthesis to live-cell and luminescent plate-reader assays, offering a practical platform for studying immunoproteasome function and screening small-molecule modulators.
