title: Differential effects of tannic acid on cisplatin induced nephrotoxicity in rats.
abstract: Cisplatin is a widely used antineoplastic drug. Major drawback of cisplatin therapy is its nephrotoxicity. The objective of this study was to check the effect of tannic acid on cisplatin induced nephrotoxicity. Post-treatment of tannic acid prevents cisplatin (5mg/kg) induced nephrotoxicity and decreases poly(ADP-ribose) polymerase cleavage, phosphorylation of p38 and hypoacetylation of histone H4. In contrast, co-treatment of tannic acid potentiates the nephrotoxicity. Comparative nephrotoxicity studies show that co-treatment of tannic acid with reduced dose of cisplatin (1.5mg/kg) developed almost similar nephrotoxicity. MALDI protein profiling of plasma samples provides indirect evidence that tannic acid co-treatment increases bioavailability of cisplatin.
