Curcumin, NLRP3, and HUVEC Pyroptosis
2026-08-16
Yuan et al. showed that curcumin protects human umbilical vein endothelial cells from H2O2-induced injury by suppressing NLRP3-associated pyroptosis and improving endothelial functional markers. The study connects oxidative stress, inflammasome activation, and endothelial dysfunction, while pharmacological inhibition with VX-765 and MCC950 strengthened the mechanistic interpretation.

NF 449 and Gsα-Selective G Protein Antagonism
2026-08-15
The 1998 PNAS study identified NF449 and NF503 as suramin analogues that preferentially antagonize Gsα-dependent signaling rather than broadly inhibiting heterotrimeric G proteins. Its combination of GTPγS-binding kinetics, adenylyl cyclase rescue, and receptor-coupling assays established a practical framework for subtype-selective G protein inhibition and clarified why NF 449 should not be interpreted solely through its later P2X1 applications.
