Ischemia/reperfusion (I/R)-induced acute kidney injury (AKI) is evoked by diverse
pathophysiological conditions and/or surgical procedures. Here, we evaluated the
nephropreventive effect of sulfotransferase (SULT) inhibitors, quercetin, and
resveratrol, which hamper hepatic indoxyl sulfate (IS) production. I/R of the
kidney caused severe renal injury with marked accumulation of serum and renal IS
and urinary excretion of kidney injury molecule-1. Oral administration of AST-120
resulted in a significant restoration of kidney injury, suggesting that uremic
toxins, which can be suppressed or adsorbed by AST-120 in the intestine,
contribute to the progression or development of I/R-induced AKI. Oral
administration of resveratrol or quercetin, SULT inhibitors, suppressed IS
accumulation, accompanied by significant amelioration of renal dysfunction. The
expression of nuclear factor E2-related factor 2 (Nrf2) in the renal nuclear
fractions was markedly elevated by renal I/R, but suppressed by treatment with
SULT inhibitors. IS is primarily taken up by HK-2 cells derived from human
proximal tubular cells via organic anion transporters, which then evokes
activation of Nrf2, most likely due to intracellular oxidative stress. Renal
basolateral organic anion transporters OAT1 and OAT3, which mediate renal tubular
uptake of IS in basolateral membrane, were markedly downregulated by renal I/R,
but restored by SULT inhibitors. Our results suggest that renal accumulation of
IS in ischemic AKI induces oxidative stress and downregulation of organic anion
transporters resulting in kidney damage, which could be restored to some extent
by inhibiting hepatic SULT activity as a nephropreventive target.
