() has been demonstrated to exhibit beneficial effects against various metabolic diseases, but whether has an anti-hyperuricemia effect remains unexplored. In this study, live and pasteurized were examined for their efficacy in alleviating hyperuricemia in mice. Live and pasteurized (approximately 2 × 10 CFU) were given to a hyperuricemic mice model oral gavage for three weeks. Both forms of decreased serum urate and inhibited xanthine oxidase in the liver. In addition, fecal and urinal urate was increased in both treatment groups, which corresponds to the changes in the mRNA and protein expression levels of renal uric acid-related transporters (URAT1, GLUT9, and ABCG2) and intestinal ABCG2. Both forms of bacteria reduced the mRNA expression of inflammatory factors in the liver, kidneys and colon. Live enhanced the expression of tight junction proteins and improved the dysbiosis of intestinal flora. These findings suggest that both live or pasteurized could effectively attenuate hyperuricemia by moderating uric acid metabolism and inflammation, and live bacteria exhibit additional beneficial effects on the gut microbiota. These findings highlight that could be potentially developed as a probiotic or postbiotic to combat hyperuricemia.
()已被证明对各种代谢性疾病具有有益的作用,但 是否具有抗高尿酸血症的作用仍未被探索。在这项研究中,研究了活菌和巴氏杀菌 的缓解小鼠高尿酸血症的功效。给高尿酸血症小鼠模型口服灌胃活菌和巴氏杀菌菌(约 2×10CFU)各 3 周。两种形式的 均可降低血清尿酸水平,并抑制肝脏黄嘌呤氧化酶。此外,粪便和尿液中的尿酸在两个治疗组中均增加,这与肾脏尿酸相关转运蛋白(URAT1、GLUT9 和 ABCG2)和肠道 ABCG2 的 mRNA 和蛋白表达水平的变化相对应。两种形式的细菌均降低了肝脏、肾脏和结肠中炎症因子的 mRNA 表达。活菌增强了紧密连接蛋白的表达,并改善了肠道菌群失调。这些发现表明,活菌和巴氏杀菌 均可通过调节尿酸代谢和炎症有效减轻高尿酸血症,而活菌对肠道微生物群具有额外的有益作用。这些发现强调了 作为益生菌或后生元来对抗高尿酸血症的潜在可能性。
