• Charge-Reversed Exosomes for Cartilage mRNA Delivery

  2026-09-26

  Zhang and colleagues engineered cationic, charge-reversed exosomes to move reporter mRNA through the negatively charged cartilage matrix, a barrier that limits conventional delivery. The study reports deeper cartilage penetration and chondrocyte EGFP expression than with native exosomes, while leaving therapeutic efficacy and long-term safety for future testing.

• Mdivi-1 Workflows for Mitochondrial Fission Research

  2026-09-25

  Use Mdivi-1 to test how mitochondrial fission contributes to hypoxia-associated apoptosis, while pairing drug treatment with mitochondrial, cell-death, and microbiome readouts. A practical workflow separates product-recommended starting conditions from study-specific details that must be verified in the full methods.

• Sex Differences in Angiotensin II Hypertension

  2026-09-25

  Xue and colleagues used telemetry in conscious mice to show that chronic angiotensin II produced a substantially larger blood-pressure rise in intact males than females, with gonadectomy shifting the response in opposite directions by sex. Their measurements also connect the pressure phenotype to altered baroreflex control and a larger ganglionic-blockade-sensitive component in males, while leaving the precise hormonal and neural mechanisms unresolved.

• Caspase-3–NDUFS1 Axis in Trichothecene Liver ROS

  2026-09-24

  A non-peer-reviewed preprint proposes that caspase-3 cleavage of the complex I subunit NDUFS1 amplifies mitochondrial ROS after DON and T-2 toxin exposure, while ER-localized ERO1α contributes a second source of oxidative stress. The findings suggest a connected mitochondrial–ER redox response and identify experiments that can test its contribution to liver-cell injury.

• TNF-alpha Recombinant Murine Protein in Death Assays

  2026-09-24

  Learn how TNF-alpha recombinant murine protein can help distinguish receptor-driven cell death from RNA Pol II degradation-dependent apoptosis. This assay-focused guide translates recent mechanistic findings into practical controls, interpretation rules, and product-handling considerations.

• Gastrin I (human): Reliable Assay Workflows

  2026-09-23

  Practical guidance for using Gastrin I (human), SKU B5358, in receptor-focused gastric physiology experiments and interpreting cell-based assay results. Covers peptide handling, vehicle controls, workflow parameters, model limitations, and evidence-based product selection.

• Cytarabine (AraC): Mechanism and Research Use

  2026-09-23

  Cytarabine, also called AraC, is a deoxycytidine-related nucleoside analog DNA synthesis inhibitor. Its activity depends on deoxycytidine kinase activation, DNA incorporation, and inhibition of polymerase-dependent synthesis, making it a useful leukemia chemotherapy agent and apoptosis research tool.

• Human SAN–Cardiac Plexus Assembloids Model Maturation

  2026-09-22

  The reference study develops human pluripotent stem cell-derived assembloids that combine sinoatrial node, cardiac ganglionated plexus, and atrial-like tissues to model innervation-associated pacemaker maturation. By integrating electrophysiology with human SAN spatial transcriptomics, the work identifies a prosaposin–GPR37 signaling program and establishes a platform for investigating neuro-cardiac control and conduction disease.

• iPSC Cardiomyocytes for Chemical Hazard and Risk

  2026-09-22

  The reference study demonstrates that combining functional phenotypes with whole-transcriptome responses in human iPSC-derived cardiomyocytes can improve chemical hazard prioritization and mechanistic interpretation. Its concentration-response framework shows that transcriptomic and phenotypic points of departure can provide broadly comparable risk-characterization results while answering different biological questions.

• Gramine, CUL3–MTDH, and Ferroptosis in TNBC

  2026-09-21

  A 2026 study identifies gramine as a selective suppressor of triple-negative breast cancer and defines a CUL3–MTDH ubiquitination mechanism that promotes ferroptosis. By combining chemical screening, target-engagement assays, genetic perturbation, rescue experiments, and xenograft models, the work connects a natural indole alkaloid to a potentially actionable ferroptosis pathway.

• How Fasting Reprograms Translation in Cancer

  2026-09-21

  Yang et al. identify an AMPK–MNK–eIF4E signaling axis that selectively remodels liver translation during fasting and ketogenic feeding, despite reduced global protein synthesis. The study links fatty-acid sensing, ketone-body production, and pancreatic tumor growth, while defining how dietary and translational interventions may be combined.

• DFO: A Decision Framework for Fingerprint Assays

  2026-09-20

  DFO, or 9H-1,8-Diazafluoren-9-one, is more than a fluorescent fingerprint reagent: its value depends on substrate, chemistry, imaging, and controls. This evidence-focused guide explains how to design defensible latent print workflows and interpret assay results without overextending the chemistry.

• Recombinant Mouse Macrophage Colony Stimulating Factor

  2026-09-19

  Build more reproducible mouse macrophage, fibrosis, osteoclast, and tumor-cell assays with a defined, tag-free M-CSF input. This guide connects practical culture controls to the IGF2BP1-THBS1-TLR4 findings in pulmonary fibrosis research while separating validated evidence from workflow recommendations.

• Mdivi-1 for Reliable Mitochondrial Assays

  2026-09-18

  This scenario-driven guide explains how Mdivi-1 (SKU A4472), a selective DRP1 inhibitor, can strengthen mitochondrial dynamics, apoptosis, and cell-viability workflows. It covers assay design, DMSO handling, data interpretation, and practical product-selection criteria using supplier information and peer-reviewed evidence.

• Mdivi-1 for DRP1-Linked Apoptosis Assays

  2026-09-18

  Mdivi-1 is a cell-permeable selective DRP1 inhibitor for connecting mitochondrial fission with cytochrome c release, annexin V positivity, and tissue injury. This practical guide translates cell, animal, and multi-omics findings into assay workflows, controls, and troubleshooting decisions.
