• GPR35–KLF5 Circuitry in Mucosal Repair

  2026-08-12

  The reference study identifies a tryptophan–kynurenine–kynurenic acid sensing mechanism in which GPR35 converts metabolic damage signals into KLF5-dependent intestinal epithelial repair. Its findings connect metabolite surveillance with PI3K–AKT–mTOR signaling, epithelial proliferation, and migration, providing a mechanistic framework for ulcerative colitis research and DSS-based injury models.

• UbIA-MS Maps the Ubiquitin Interaction Landscape

  2026-08-11

  Zhang et al. introduced UbIA-MS, a quantitative affinity-enrichment mass spectrometry workflow that uses chemically synthesized diubiquitin to profile linkage-dependent ubiquitin interactors. The study revealed selective and damage-responsive interaction programs, including K6 recognition by TAB2/TAB3 and K27-linked ubiquitin regulation by UCHL3.

• Artesunate: Mechanisms and Cancer Research Workflow

  2026-08-11

  Artesunate is an artemisinin derivative investigated as an anticancer compound in ferroptosis, pyroptosis, and AKT/mTOR studies. Product-level data report an IC50 below 5 μM in H69 small cell lung carcinoma cells under supplier-reported assay conditions, while rigorous response profiling should distinguish growth inhibition from cell killing.

• SU 5402 in Human Neuron Signaling Assays

  2026-08-10

  SU 5402 can serve as a mechanistic probe for receptor tyrosine kinase signaling in cancer biology and emerging human sensory-neuron models. This article connects its validated kinase activity with assay-design lessons from a scalable HSV-1 latency system while clearly separating evidence from testable hypotheses.
