Abstract
To investigate the changes of uric acid metabolism in rats during prolonged fasting and its potential regulatory mechanism. Sprague-Dawley (SD) rats were used as animal models. The changes of uric acid level and metabolism-related gene and protein expression in rats during different fasting periods (1, 2, 3, 5, and 7 days) were analyzed by pathological tissue sections, biochemical tests, quantitative PCR (qRT-PCR), and western blotting. The results showed that prolonged fasting did not cause significant damage to kidney tissue, but remarkedly increased the blood uric acid level and blood uricase activity. It also resulted in fluctuating changes in urine uric acid level. The mRNA and protein expression levels of main uric acid transporters were increased gradually with the fasting duration. The elevation of serum uric acid caused by prolonged fasting is related to uric acid transporter and uricase activity.
