  The Aconitase Activity Colorimetric Assay Kit provides a rapid functional readout of aconitase within TCA cycle and oxidative-stress studies. This guide connects the assay to CD28–ARS2-driven T-cell metabolic flexibility while defining what the measurement can—and cannot—show.

• CD44 Metabolic Rewiring in IDH-Mutant Leukemia

  2026-08-17

  Lyu and colleagues identify CD44 as a functional metabolic dependency in IDH-mutant leukemia, linking adhesion signaling to pentose phosphate pathway activity, NADPH production, and sustained R-2HG synthesis. The study suggests that combining mutant-IDH inhibition with CD44 blockade may address a metabolic requirement that helps leukemia cells maintain the oncometabolite state.

• BBB Permeability Prediction and Lysosomal Trapping

  2026-08-17

  Hu et al. developed a high-throughput Transwell surrogate blood-brain barrier model using LLC-PK1-MOCK/MDR1 cells and incorporated bafilomycin A1 correction for lysosomal trapping. Its correlation with unbound brain-to-plasma distribution supports early CNS compound prioritization while clarifying the difference between passive diffusion, P-glycoprotein efflux, and intracellular sequestration.

• Berberine Hydrochloride and the Gut–Bone Axis

  2026-08-16

  Berberine hydrochloride is moving beyond conventional metabolic and antibacterial research as a mechanistic probe of gut–bone communication. New preclinical evidence connects microbiota-derived butyrate, intestinal tuft cells, barrier repair, and osteoimmune balance, creating a disciplined framework for translational studies.

• SEMA3E Drives Beige Fat Thermogenesis via β-Catenin

  2026-08-14

  The reference study identifies SEMA3E as a regulator of beige adipocyte differentiation and non-shivering thermogenesis in mice, connecting its activity to mitochondrial oxidative phosphorylation and Wnt/β-catenin signaling. Its combination of tissue-specific gene manipulation, transplantation, transcriptomics, and mitochondrial respiration assays provides a mechanistic framework for studying adipose remodeling, while leaving important questions about pathway directionality and human translation unresolved.

• Lithium, Exosomal Wnt10a, and Bone Regeneration

  2026-08-14

  The reference study identifies an exosome-centered mechanism by which lithium enhances bone mesenchymal stem cell osteogenesis: MARK2-associated Rab11a/Rab11FIP1 trafficking increases exosomal Wnt10a delivery and activates β-catenin signaling. Its comparison of lithium-conditioned exosomes with control exosomes, followed by GelMA hydrogel testing, provides a mechanistic and biomaterials framework for improving bone repair.

• Semaphorin Receptors Antagonize Wnt Signaling

  2026-08-13

  This preprint identifies Neuropilin and Plexin semaphorin receptors as previously unrecognized antagonists of Wnt signaling, acting downstream of Dishevelled to promote proteasome-dependent β-catenin destabilization. Its receptor-specific results provide a framework for separating GSK3/CK1-dependent regulation from broader pathway effects when designing Wnt-focused cell assays.
