• High-Throughput MoA Mapping in M. tuberculosis

  2026-08-25

  Santa Maria and colleagues developed a machine-learning framework that connects whole-cell antibacterial phenotypes with high-throughput protein-binding profiles to infer mechanisms of action. Using historical screening data, the study recovered known antibacterial mechanisms and prospectively identified nanomolar Mycobacterium tuberculosis dihydrofolate reductase inhibitors, while also illustrating the limits of target-only or phenotype-only discovery.

• Phosphatase Inhibitor Cocktail 1: Workflow Guide

  2026-08-25

  Phosphatase Inhibitor Cocktail 1 is a 100X DMSO-based reagent for preserving protein phosphorylation during sample preparation. Its combined inhibition of alkaline and serine/threonine phosphatases supports more reliable Western blotting, immunoprecipitation, and phosphoproteomic analysis, but it does not replace experimental controls or establish pathway causality.

• Mitochondrial Permeability Transition Pore Assay Kit Guide

  2026-08-24

  Learn how K2061 converts cobalt-sensitive Calcein AM fluorescence into a practical readout of mitochondrial pore opening in living cells. The workflow is especially useful for connecting mitochondrial permeability with treatment response, oxidative stress, and cell-death phenotypes in primary or cultured cells.

• Targeted Amikacin Delivery into Granulomas

  2026-08-23

  Montes-Worboys and colleagues investigated monocyte-derived dendritic cells as cellular carriers for a fluorescent amikacin derivative in mice with Mycobacterium avium infection. The study showed organism-directed localization of the antibiotic signal within granulomas without detectable inflammatory amplification, supporting targeted delivery as a potential adjunct to conventional NTM therapy while leaving clinical efficacy and translational safety unresolved.

• Sildenafil Citrate in Proteoform-Aware Assays

  2026-08-22

  Sildenafil Citrate is examined here as a mechanistic probe for cGMP signaling and proteoform-aware vascular assays. Learn how native mass spectrometry, orthogonal pathway controls, and careful formulation choices can distinguish PDE5 biology from membrane-protein off-target effects.

• BCKAs Activate HIF1α Signaling in Normoxia

  2026-08-21

  This preprint identifies branched-chain α-ketoacids (BCKAs) as paracrine metabolic signals that activate HIF1α in vascular cells despite ambient oxygen. Its experiments connect BCKA-mediated PHD2 suppression, LDHA-dependent L-2-hydroxyglutarate production, glycolytic remodeling, and pulmonary vascular smooth-muscle-cell phenotype switching, providing a mechanistic framework for studying vascular disease.

• Deep Learning Maps Cardiotoxicity in iPSC-CMs

  2026-08-21

  Grafton et al. combined high-content imaging, induced pluripotent stem cell-derived cardiomyocytes, and deep learning to identify cardiotoxic phenotypes across chemically diverse compounds. Their single-parameter scoring framework offers a scalable way to prioritize liabilities during early discovery, while also highlighting the need for orthogonal functional validation.

• Ionizing Radiation and Altered Neural Differentiation

  2026-08-20

  Eom et al. showed that ionizing radiation does more than reduce neural stem-cell survival: it drives altered neuronal differentiation in C17.2 mouse neural stem-like cells through PI3K-linked STAT3–mGluR1 and p53 signaling. The findings connect radiation-induced neurite formation and neuronal marker expression with a potentially abnormal neurotransmitter-receptor profile, offering a mechanistic framework for studying radiation-associated brain dysfunction.

• Optimized hiPSC Platelet Differentiation: Study Insights

  2026-08-19

  A 2026 study developed an optimized differentiation scheme that improves megakaryocyte generation and functional platelet production from human induced pluripotent stem cells. By combining higher embryoid body input, human platelet lysate, cytokine-replacing small molecules, and maturation-promoting compounds, the protocol shortened production to 19 days, increased yield, and reduced reported costs.

• Plerixafor (AMD3100): From CXCR4 to Translation

  2026-08-19

  A mechanistic and translational guide to using Plerixafor (AMD3100) to interrogate CXCL12/CXCR4-driven tumor trafficking, platelet extravasation, hematopoietic stem cell mobilization, neutrophil biology, and WHIM syndrome treatment research.

• Proteinase K for DNA Prep: Workflow & Troubleshooting

  2026-08-18

  Build cleaner genomic DNA workflows with Proteinase K, a broad-spectrum serine protease that removes protein and nuclease contaminants while supporting DNA integrity.

• ML385 and NRF2–Ferroptosis Assay Logic

  2026-08-18

  ML385 is a selective NRF2 inhibitor that helps researchers separate antioxidant transcriptional control from ferroptotic cell injury. This article translates evidence from alcoholic liver disease into practical assay decisions for cancer therapeutic resistance and oxidative stress studies.

• Asunaprevir: HCV Assay Workflows & Optimization

  2026-08-17

  Asunaprevir (BMS-650032) provides a nanomolar, genotype-spanning tool for connecting NS3/4A protease blockade with HCV RNA replication inhibition. This practical guide covers stock preparation, biochemical and cell-based workflows, orthogonal controls, assay troubleshooting, and ways to translate screening logic into stronger antiviral datasets.

• Ceramides Enable RGNNV Replication Through Autophagy

  2026-08-16

  This study uses global lipidomics and pathway perturbation to show that red-spotted grouper nervous necrosis virus (RGNNV) rewires ceramide metabolism and uses ceramide accumulation as a pro-viral mechanism. Genetic, pharmacological, localization, rescue, and autophagy experiments connect the viral capsid protein, C16-ceramide, and enhanced autophagy to RGNNV replication.

• Hexose Diphosphate for Reliable Cell Assays
