• Protease Inhibitor Cocktail for MS Workflows

  2026-09-30

  This AEBSF-free Protease Inhibitor Cocktail provides broad protection against endogenous proteolysis during cell and tissue protein extraction while limiting one known source of mass-spectrometry interference. It is intended for lysates and biochemical workflows, not as a universal live-cell, in vivo, phosphatase, or metalloproteinase-control reagent without separate validation.

• DFCP1 Controls Starvation-Driven Lipolysis

  2026-09-29

  The reference study identifies DFCP1/ZFYVE1 as a nutrient-sensitive regulator of lipid droplet catabolism that recruits and retains ATGL on lipid droplets during starvation. Its findings connect DFCP1 localization and ATGL dynamics to control of lipolysis, while also providing a framework for preserving labile protein interactions during related extraction and biochemical assays.

• Marein Reverses Mitoxantrone Resistance via ABCG2

  2026-09-29

  The reference study identifies marein, a chalcone glucoside from Coreopsis tinctoria, as a competitive inhibitor of ABCG2-mediated drug efflux. By increasing intracellular exposure to ABCG2 substrates such as Mitoxantrone, marein restored chemotherapy sensitivity in resistant cancer-cell models and connected this activity to the conserved F439 residue.

• DFCP1 Regulates Starvation-Driven ATGL Lipolysis

  2026-09-28

  The reference study identifies DFCP1/ZFYVE1 as a nutrient-sensitive regulator of adipose triglyceride lipase (ATGL) on lipid droplets during starvation. Its experiments support a mechanism in which DFCP1 recruits ATGL and limits its dynamic dissociation, thereby slowing lipid droplet lipolysis and refining current models of lipid mobilization.

• OsCPK4–OsCNGC7 Feedback Tunes Rice Salt Tolerance

  2026-09-28

  The study identifies a phosphorylation-centered module in which OsCPK4 activates the Ca²⁺-permeable channel OsCNGC7 during early salt stress, promoting calcium influx and salt tolerance in rice. Its time-dependent regulation also reduces channel phosphorylation and abundance during prolonged stress, suggesting a way to balance rapid defense with subsequent growth recovery.

• Ceramides Promote RGNNV Infection Through Autophagy

  2026-09-27

  Global lipidomics and complementary perturbation experiments show that red-spotted grouper nervous necrosis virus (RGNNV) shifts host sphingolipid metabolism toward ceramide accumulation. In the study, disrupting ceramide production reduced infection, while C16-ceramide restored viral replication and promoted an autophagy-associated response, identifying ceramide metabolism as a candidate host–virus interaction point.

• CUDC-907: Practical Dual PI3K and HDAC Workflow

  2026-09-26

  CUDC-907 is a dual PI3K and HDAC inhibitor for controlled cancer-cell experiments that examine signaling, histone acetylation, cell-cycle behavior, and apoptosis. This guide outlines preparation and assay controls; the compound is for scientific research only, not diagnostic, therapeutic, or clinical use.

• Cy7 NHS Ester: Labeling and QC Workflow

  2026-09-25

  Sulfo-Cy7 NHS Ester provides a water-soluble near-infrared dye for bioimaging workflows that label accessible amino groups on proteins or peptides. Use it for aqueous biomolecule conjugation and near-infrared fluorescent imaging; it is not a general label for non-amine targets, and prepared dye solutions should not be stored long term.

• S-Nitrosylation Balances Arabidopsis Aluminum Resistance

  2026-09-25

  The study identifies nitric oxide-dependent S-nitrosylation as a way to regulate two distinct aluminum-resistance pathways in Arabidopsis: it destabilizes STOP1 while stabilizing STAR1. This opposing control links external aluminum detoxification with internal sequestration and suggests a molecular basis for coordinating the two responses, while leaving open how broadly the mechanism applies beyond Arabidopsis.

• EDTA-Free Protease Inhibitor for OXPHOS Studies

  2026-09-24

  Protect protein-level readouts when investigating LRPPRC inhibition and dasatinib-driven OXPHOS disruption. This practical guide shows how to use an EDTA-free, broad-spectrum cocktail during extraction—without confusing protein preservation with evidence of transcript changes or drug synergy.

• Protease Inhibitor Cocktail: K1008 Workflow Guide

  2026-09-24

  K1008 helps limit proteolysis during protein extraction and downstream analyses, including Western blotting and co-immunoprecipitation. Its EDTA-free formulation suits workflows that need to retain divalent cations, but it is not a substitute for EDTA when chelation-dependent metalloprotease inhibition is required; DMSO-sensitive assays also need compatibility checks.

• Pifithrin-α for p53-Linked Ferroptosis Workflows

  2026-09-23

  Pifithrin-α (PFTα) offers a practical way to test whether p53 activity contributes to stress-induced cell injury—not just whether a treatment changes viability. This workflow connects the reference study’s deltamethrin–ferroptosis findings to focused HT-22 assays, with solvent controls, pathway readouts, and clear limits on interpretation.

• Endothelial USP8 Controls Angiogenesis

  2026-09-23

  The reference study establishes a stage-dependent, in vivo requirement for endothelial USP8 during embryonic and postnatal angiogenesis, while finding no overt vascular phenotype after adult deletion. Its mechanistic data connect USP8 loss to VEGFR2 accumulation in early endosomes, reduced ERK signaling, impaired endothelial cell-cycle activation, and abnormal vessel morphology.

• Leupeptin Hemisulfate: Protease Workflow Guide

  2026-09-22

  Leupeptin hemisulfate salt provides reversible, competitive control of serine and cysteine proteases across protein stabilization, autophagy, and antiviral workflows. This guide connects practical inhibitor handling with the metabolite-binding logic of a recent TET2 assay protocol, while clearly separating established evidence from assay-development recommendations.

• Early Life Adversity, Oxytocin, and Defensive Vision

  2026-09-22

  A 2026 Communications Biology study links early life adversity to impaired looming-evoked defensive behavior through reduced oxytocin signaling in the superior colliculus. Its combination of behavioral, molecular, circuit, and pharmacological evidence identifies the oxytocin–superior colliculus pathway as a mechanistic framework for studying how childhood stress alters innate threat processing.
