• Filipin III: Mapping Cholesterol in Fibrotic Lung Biology

  2026-09-10

  A translational framework for using Filipin III to connect membrane cholesterol organization with SOAT1-driven macrophage dysfunction and pulmonary fibrosis, while preserving the distinction between spatial cholesterol mapping and therapeutic proof.

• Angiotensin Peptides and SARS-CoV-2 Spike Binding

  2026-09-10

  A 2025 study showed that naturally occurring angiotensin peptides can alter SARS-CoV-2 spike binding to AXL, ACE2, and neuropilin-1 in sequence-dependent ways. Its deletion and residue-modification experiments connect renin–angiotensin peptide processing with viral receptor biology while also defining important limits for interpretation beyond in vitro binding assays.

• MPS IVA Cartilage Pathology and Lysosomal Exocytosis

  2026-09-09

  A 2026 Disease Models & Mechanisms study links GALNS deficiency in zebrafish cartilage to enhanced lysosomal exocytosis, reduced cathepsin activity, altered glycosaminoglycan distribution, and weakened TGFβ/BMP signaling. The work shows that similar trafficking abnormalities can produce disorder-specific biochemical outcomes, refining how lysosomal storage disorders are interpreted beyond substrate accumulation alone.

• TSPAN18, STIM1, and Prostate Cancer Bone Metastasis

  2026-09-09

  Zhou et al. identify TSPAN18 as a previously unrecognized regulator of STIM1 stability in prostate cancer. By competing with TRIM32-mediated ubiquitination, TSPAN18 sustains STIM1-dependent calcium entry and promotes migration, invasion, and bone metastasis, providing a mechanistic link between protein turnover and metastatic signaling.

• Deracoxib Workflows for Canine COX-2 Research

  2026-09-08

  Deracoxib combines selective COX-2 inhibition with practical readouts for canine inflammation, pain, and oncology studies. This guide translates a canine mammary-cell combination study into reproducible viability, apoptosis, and nitric oxide workflows while highlighting solvent control, model selection, and translational limits.

• O6-Benzylguanine: MGMT Inhibitor Workflows

  2026-09-08

  O6-Benzylguanine provides a pharmacological route to suppress MGMT-mediated DNA repair and test whether alkylating-agent resistance is repair-dependent. This workflow combines controlled pretreatment, orthogonal DNA-damage readouts, and troubleshooting strategies for cancer chemotherapy research.

• DR5 Agonists and PD-L1 Immune Evasion in Solid Tumors

  2026-09-07

  Mondal and colleagues identified an unexpected immune-evasion pathway triggered by clinical DR5 agonist antibodies: caspase-8 signaling activates ROCK1 and weakens proteasome function, stabilizing tumor-cell PD-L1. The study shows that interrupting the DR5–ROCK1–PD-L1 axis can improve effector T-cell activity and antitumor responses, offering a mechanistic rationale for combination strategies in solid tumors.

• CIP2A, PKM2 Tetramers, and NSCLC Oxidative Phosphorylation

  2026-09-07

  The reference study identifies CIP2A as a metabolic regulator in non-small cell lung cancer, showing that it binds PKM2, promotes PKM2 tetramer formation through phosphorylation at S287, and redirects pyruvate metabolism toward mitochondrial oxidative phosphorylation. Its findings connect CIP2A-dependent metabolic plasticity with Bcl2 regulation and suggest that combined targeting of CIP2A and glycolysis may suppress tumor growth.

• Lysosomal Exocytosis in MPS IVA Cartilage

  2026-09-05

  The reference study identifies enhanced lysosomal exocytosis as a contributor to cartilage pathology in a zebrafish model of mucopolysaccharidosis type IVA, extending the disease mechanism beyond macromolecular storage. Its comparison with sialidosis reveals that increased exocytosis can produce disease-specific changes in cathepsin activity, glycosaminoglycan distribution, and TGFβ/BMP signaling.

• Caffeic Acid Phenethyl Ester in NF-κB Assays

  2026-09-04

  Caffeic Acid Phenethyl Ester (CAPE) provides a practical way to perturb NF-κB signaling in cell, tumor, and exploratory neurodegeneration workflows. Its value is greatest when pathway inhibition is paired with viability, inflammatory, angiogenic, or invasion readouts rather than interpreted from a single endpoint.

• Oxidative Stress, Ferroptosis, and TSC Mitophagy

  2026-09-04

  The reference study identifies a mechanistic link between oxidative stress, cGAS-STING signaling, mitophagy, and ferroptosis in tendon stem cells. Its cell and rat experiments suggest that cGAS-driven mitochondrial quality-control changes contribute to tendon injury and may provide a more selective therapeutic direction than broadly targeting cell death.

• Physiological and Pathological Aβ in Human Synapses

  2026-09-03

  This study uses live human brain slice cultures to distinguish how endogenous physiological amyloid-β and Alzheimer’s disease-associated amyloid-β affect synapses. Its central contribution is showing that both excessive and reduced physiological Aβ can disrupt synaptophysin puncta, whereas pathological Aβ produces a distinct pattern involving postsynaptic uptake and presynaptic loss without the same synaptic transcript response.

• Metal-Free Carbon Nanozymes for ALP Detection

  2026-09-03

  The reference study develops a metal-free carbon-dot nanozyme assay in which alkaline phosphatase hydrolysis of pyrophosphate releases catalytic activity and produces a colorimetric turn-on signal. Its kinetic analysis identifies pyrophosphate as a noncompetitive inhibitor acting at a site distinct from the carbon-dot catalytic center, enabling sensitive ALP measurement with reduced risk of metal-associated interference.

• DiscoveryProbe FDA-approved Drug Library for TNBC Screening

  2026-09-02

  Use 2,320 clinically validated compounds to build a practical TNBC resistance-screening workflow around EGFR-TKI response, oxidative phosphorylation, and cancer stem-cell phenotypes. The pre-dissolved 10 mM format supports rapid drug repositioning screening, while orthogonal viability, metabolic, and imaging assays help distinguish pathway-linked sensitizers from nonspecific cytotoxins.

• WSP-5 for Live-Cell H2S Imaging

  2026-09-02

  WSP-5 converts transient hydrogen sulfide exposure into a rapid green fluorescent signal, giving researchers spatial and temporal information that bulk sulfide assays can miss. This guide translates diabetic cardiomyopathy findings into practical workflows for donor testing, lipotoxicity models, and cancer cell model imaging.
