Comparison between Annona squamosa, Annona cherimolia and Annona atemoya ethanolic extracts extenuative impact against oxidative stress, inflammation and apoptosis in rat kidney induced by Ifosfamid

Abstract

Up-regulation of NF-kB and depletion of glutathione are acceptable mechanisms of Ifosfamide (IFO) renal toxicity. This investigation elucidates the role of free radicals, inflammatory and apoptotic markers in ifosfamide-induced rentoxicity and the protection of Annona species planted in Egypt (squamosa, cherimolia), and the hybrid between them (atemoya). Annona seeds extracts were prepared and phytochemical analyses were assessed. Rats were injected with saline or with IFO alone or in combination with Annona squamosa or Annona cherimolia or Annona atemoya orally. Biochemical, gene expression, histological and immune-histological examinations were performed. The results demonstrated that IFO elevated creatinine, sodium, magnesium and urea, along with depleted serum potassium and albumin levels. IFO caused a significant reduction in renal GSH, significant increases in renal MDA, and NOx, and up-regulated iNOS. In addition, IFO treatment showed increase mRNA and protein expression of NF-kB, while down-regulated mRNA and protein expression of Bcl-2, and strong immunohistological expression of caspase-3 as well as BAX in kidney tissues. Different Annona seed extracts significantly enhanced the sharpness of renal injury and improved oxidant responses induced by IFO. Annona extracts down-regulated iNOS, NF-kB expressions, as well as, down-regulated caspase-3 and BAX immunohistological expressions, and up-regulated Bcl-2 expression. A. squamosa showed a more pronounced protective effect. Histopathological examination was in accordance with biochemical results. Recent results suggest that Annona species ameliorated the renal toxicity of ifosfamide by down-regulation of NOx, iNOS, NF-kB, BAX, caspase-3 and MDA in addition to up-regulation of GSH and Bcl-2.
