    AbstractAlthough doxorubicin (DXR) is an important antineoplastic agent, the serious toxicity mediated by the production of reactive oxygen species has remained a considerable clinical problem. Our hypothesis is that tanshinone II A sodium sulfonate (TSNIIA-SS), which holds significant effects against oxidative stress, protects against DXR-induced nephropathy. Firstly, the antioxidative effects of TSNIIA-SS were confirmed using oxygen radicals absorbance capacities (ORAC) assay in vitro. Then, DXR nephropathy was induced by repeated DXR treatment and verified by kidney index (20.76 ± 3.04 mg/mm versus 14.76 ± 3.04 mg/mm, p < 0.001) and histochemical stain. The mice were randomized into three groups: Control group, DXR group and DXR-TSNIIA-SS group. TSNIIA-SS treatment not only improved DXR lesion identified by histochemical stain, but also regulated the expression of several proteins related with the cytoskeleton, oxidative stress and protein synthesis or degradation detected by two-dimensional electrophoresis (2-DE). These data have provided the evidence that TSNIIA-SS is a protective agent against DXR-induced nephropathy.
