Kaempferol attenuates hyperuricemia combined with gouty arthritis via urate transporters and NLRP3/NF-κB pathway modulation.

Hyperuricemia (HUA), caused by purine disorders, can lead to gouty arthritis (GA). Kaempferol (KPF), a natural flavonoid, has anti-inflammatory properties, though its mechanism in treating HUA combined with GA remains unclear. This study used a mouse model of HUA combined with GA and models with HK-2 and THP-1 cells to explore KPF's effects.

Astilbin inhibited neutrophil extracellular traps in gouty arthritis through suppression of purinergic P2Y6 receptor.

Background: Gouty arthritis (GA), a common inflammatory condition triggered by monosodium urate crystal accumulation, often necessitates safer treatment alternatives due to the limitations of current therapies. Astilbin, a flavonoid from Smilax glabra Roxb, has demonstrated potential in traditional Chinese medicine for its anti-inflammatory properties. However, the anti-GA effect and its underlying mechanism have not been fully elucidated.

Targeting Neutrophil Extracellular Traps in Gouty Arthritis: Insights into Pathogenesis and Therapeutic Potential.

Gouty arthritis (GA) is an immune-mediated disorder characterized by severe inflammation due to the deposition of monosodium urate (MSU) crystals in the joints. The pathophysiological mechanisms of GA are not yet fully understood, and therefore, the identification of effective therapeutic targets is of paramount importance. Neutrophil extracellular traps (NETs), an intricate structure of DNA scaffold, encompassing myeloperoxidase, histones, and elastases - have gained significant attention as a prospective therapeutic target for gouty arthritis, due to their innate antimicrobial and immunomodulatory properties.

Exploring the causal associations of micronutrients on urate levels and the risk of gout: A Mendelian randomization study.

Background & Aims: Growing evidence has indicated a potential association between micronutrient levels, urate levels, and the risk of gout. However, the causal association underlying these associations still remains uncertain. Previous observational studies and randomized controlled trials investigating the association between micronutrients, urate levels, and the risk of gout have been limited in their scope and depth.

Curcumin attenuates potassium oxonate-induced hyperuricemia and kidney inflammation in mice.

Current evidences suggest that hyperuricemia is closely related to the overproduction or underexcretion of uric acid (UA). Curcumin (CUR), a natural polyphenol component extracted from the rhizome of Curcuma longa, has been reported to treat various symptoms such inflammation disease, seems to be efficacious in hyperuricemia. In this study, we aimed to investigate the effect of CUR on hyperuricemia and kidney inflammation in hyperuricemic mice.

Dendrobium officinale polysaccharides attenuate learning and memory disabilities via anti-oxidant and anti-inflammatory actions.

The aim of this study was to explore the therapeutic effect and underling mechanism of Dendrobium officinale polysaccharides (DOPS) on two well-established animal models of learning and memory disabilities. Model of estrogen deficiency caused learning and memory disability can be induced by ovariectomy in mice, and mice were injected subcutaneously with d-galactose, which can also cause cognitive decline. H&E staining and Nissl staining were employed to confirm the protective effect of DOPS on hippocampal neuron.
