Abstract
The protective effect of caffeic acid (CA) against oxidative stress-induced inhibition of proximal tubule apical transporter was investigated. In the present study, 10-4 M H2O2 did not affect cell viability regardless of incubation time, However, it decreased apical transporters' activity such as Na+/glucose cotransporter, Na+/Pi cotransporter, and Na+/H+ antiporter in the proximal tubule cells. CA (>10-6 M) prevented H2O2-induced inhibition of apical transporters. Thus, we investigated its action mechanism, CA also prevented H2O2-induced lipid peroxides formation, arachidonic acid (AA) release, and Ca2+ uptake. In conclusion, CA, in part, prevented H2O2-induced inhibition of apical transporter activity via decrease of AA release and Ca2+ uptake in primary cultured renal proximal tubule cells.
