An Investigation Into How The Prostate And Androgens Mediate Greater Levels Of Uric Acid In Males Compared To Females, Rachel D. King

Graduate Theses, Dissertations, and Problem Reports (ETD)

Chronic elevated circulating uric acid (UA) levels (hyperuricemia) are associated with gout as well as cardiovascular, metabolic, and renal dysfunction. Men have greater mean circulating UA levels than women and are more likely to exhibit hyperuricemia. This may be partly driven by the hormonal regulation of renal UA transporters; however, a direct link between hormones and UA production has not been established. Production of UA is catalyzed by xanthine oxidoreductase (XOR / XDH), which is ubiquitously expressed but has the greatest specific activity in the liver. Interestingly, an extensive gout genome-wide association study (GWAS) recently revealed a robust genetic …
