: Clinical findings have shown a negative correlation between the severity of depressive symptoms and serum uric acid levels in men, yet the role of metabolic regulation in the pathophysiology of depression remains largely unknown. : In this study, we utilized an acute restraint-stress-induced male rat model of depression to investigate biochemical changes through NMR-based metabolomics combined with serum biochemical analysis. Additionally, we employed qPCR, immunoblotting, and enzyme activity assays to assess the expression and activity of xanthine oxidoreductase, the rate-limiting enzyme in uric acid production.

Serum uric acid and nonalcoholic fatty liver disease.

Front Endocrinol (Lausanne)

December 2024

Department of Gastroenterology, Shengjing Hospital of China Medical University, Shenyang, China.

Nonalcoholic fatty liver disease (NAFLD) is characterized by over 5% hepatic fat accumulation without secondary causes. The prevalence of NAFLD has escalated in recent years due to shifts in dietary patterns and socioeconomic status, making it the most prevalent chronic liver disease and a significant public health concern globally. Serum uric acid (SUA) serves as the end product of purine metabolism in the body and is intricately linked to metabolic syndrome.

Electronic address:

Ethnopharmacological Relevance: The seeds of Hovenia acerba water extract (HAW) are used as an edible traditional Chinese medicine to treat diseases related to hyperuricemia (HUA).

Aim Of The Study: To evaluate HAW for its anti-HUA effect and to figure out their underlying mechanisms.

Materials And Methods: The anti-HUA effects were evaluated on a mouse model by testing HAW's effects on the levels of serum uric acid (SUA), the biochemical indicators of liver and kidney function, and the histology of liver and kidney.

Article Synopsis
  • * In a study, mice treated with EGT showed improved liver function and reduced symptoms of fibrosis, evidenced by lower levels of liver enzymes and key markers associated with fibrosis.
  • * Metabolomic and network pharmacology analyses suggested that EGT works through specific metabolic pathways and targets, particularly inhibiting the TGF-β/Smads signaling pathway, which could pave the way for new therapeutic strategies against liver fibrosis.
