Small-Molecule Antagonists of Shh–Heparin Binding
2026-10-03
Lamson et al. report a high-throughput discovery strategy for small molecules that disrupt Sonic hedgehog N-terminal fragment binding to heparin and inhibit selected Hedgehog responses in vitro. The study is notable because it separates ligand-level antagonism from downstream Smoothened modulation, using SAG as a mechanistic comparator rather than treating all pathway inhibition as equivalent.

IL-36R and NETs in Psoriasis: Study Insights
2026-10-02
The reference study defines a feedback circuit in which TLR3-associated stimulation and ATP–P2X7R signaling promote NET formation, while IL-36R activity amplifies inflammatory responses in psoriasiform disease. Its combination of NETosis assays, primary keratinocytes, an imiquimod model, and Il1rl2-deficient mice provides a mechanistic framework for evaluating NET–IL-36R interactions and their therapeutic relevance.

Nanoparticle Uptake in Human Corneal Cells
2026-10-01
The 2024 study by Azadi and David systematically links nanoparticle size and surface chemistry with uptake mechanisms in human corneal epithelial cells. Its in vitro model shows that energy-dependent endocytosis dominates, with macropinocytosis and caveolae-mediated uptake contributing most strongly, providing design guidance for topical ocular nanomedicines.

Capillarisenol C Drives ER Stress-Linked Autophagic Death
2026-09-28
The study links capillarisenol C, a bisphenol isolated from Artemisia capillaris, to ER stress-associated autophagic cell death in HepG2 and Huh7 liver cancer cells. Pharmacological inhibition and ATG7 knockdown support a functional role for autophagy, while rescue by 4-PBA implicates ER stress without establishing it as the compound’s sole mechanism.

Vorinostat Workflows for Cancer Biology Research
2026-09-25
Use Vorinostat to connect HDAC inhibition, chromatin changes, and apoptosis in cancer models—with timed, orthogonal readouts that distinguish cause from consequence. A recent RNA Pol II study offers a useful experimental lens, but its cell-death mechanism should be tested as a hypothesis rather than assumed to explain Vorinostat responses.

SIRT4–GDH Metabolism in Liver Fibrosis
2026-09-24
The study identifies a SIRT4–GDH axis that links glutamine catabolism to hepatic stellate cell activity and liver fibrosis. Pharmacological and genetic findings suggest that limiting glutamate conversion to α-ketoglutarate may restrain stellate-cell proliferation, although further work is needed to establish therapeutic selectivity and clinical relevance.
