Reactive oxygen species-induced TXNIP drives fructose-mediated hepatic inflammation and lipid accumulation through NLRP3 inflammasome activation.

Aims: Increased fructose consumption predisposes the liver to nonalcoholic fatty liver disease (NAFLD), but the mechanisms are elusive. Thioredoxin-interacting protein (TXNIP) links oxidative stress to NOD-like receptor family, pyrin domain containing 3 (NLRP3) inflammasome activation and this signaling axis may be involved in fructose-induced NAFLD. Here, we explore the role of reactive oxygen species (ROS)-induced TXNIP overexpression in fructose-mediated hepatic NLRP3 inflammasome activation, inflammation, and lipid accumulation.

Nuciferine restores potassium oxonate-induced hyperuricemia and kidney inflammation in mice.

Nuciferine, a major aporphine alkaloid of the leaves of Nelumbo nucifera, was found to decrease serum urate levels and improved kidney function, as well as inhibited system and renal interleukin-1β (IL-1β) secretion in potassium oxonate-induced hyperuricemic mice. Furthermore, nuciferine reversed expression alteration of renal urate transporter 1 (URAT1), glucose transporter 9 (GLUT9), ATP-binding cassette, subfamily G, membrane 2 (ABCG2), organic anion transporter 1 (OAT1), organic cation transporter 1 (OCT1), and organic cation/carnitine transporters 1/2 (OCTN1/2) in hyperuricemic mice. More importantly, nuciferine suppressed renal activation of Toll-like receptor 4/myeloid differentiation factor 88/NF-kappaB (TLR4/MyD88/NF-κB) signaling and NOD-like receptor family, pyrin domain containing 3 (NLRP3) inflammasome to reduce serum and renal IL-1β levels in hyperuricemic mice with renal inflammation reduction.
