Abstract

Objective: This study aimed to investigate the renoprotec- tive effects of paricalcitol, a synhetic vitamin D analog, through its possible roles on p38 MAPK and PI3K/Akt signaling pathways to prevent oxidative stress, inflamma- tion and apoptosis during renal I/R.Materials and methods: Total 20 kidney tissues of sham (n  6), subjected to renal I/R bilaterally for 45 min ischemia followed by 24 h reperfusion (n  7) and parical- citol (0.3 g/kg, ip) pretreated Wistar albino rats (n  7) were used in this study. Interstitial inflammation and active caspase-3 expression were evaluated histologically. TNF-, IL-1, kidney injury molecule-1 (KIM-1), MDA and SOD activity in kidneys were analysed biochemically. Fur- thermore, activation of p38 MAPK, PI3K/Akt signaling pathways and NFB p65 were evaluated by western blot. Results: Paricalcitol pretreatment significantly reduced interstitial inflammation during renal I/R, which was consistent with decreased tumor TNF-, IL-1, active caspase-3 and KIM-1 expression. Paricalcitol also reduced MDA level and attenuated the reduction of SOD activity in the kidney during I/R. Moreover, paricalcitol could suppress the p38 MAPK and NFB p65, and also activate PI3K/Akt signaling pathway during renal I/R. Conclusion: All these findings indicate that paricalcitol may be an effective practical strategy to prevent renal I/R injury.

Özet

Amaç: Bu çalışmanın amacı vitamin D’nin bir sentetik analoğu olan parikalsitol’ün renal iskemi/reperfüzyon (I/R) süresince oksidatif stres, inflamasyon ve apoptozise karşı renoprotektif etkisini p38 MAPK ve PI3K/Akt sinyal ileti yolakları üzerine olası rolleri ile araştırmaktır. Gereç ve yöntem: Sham (n  6) grubu, bilateral renal iskemi/reperfüzyon (I/R) (45 dak iskemi, 24 saat reperfüz- yon) (n  7) ve renal I/R’den önce parikalsitol (0.3 g/kg, i.p) (n  7) uygulanan Wistar albino sıçanlardan alınan toplam 20 böbrek dokusu kullanıldı. İnterstisyel inflamasyon ve aktif kaspaz-3 histolojik analizler ile değerlendirildi. Böbrek dokusunda TNF-, IL-1, böbrek hasar molekülü-1 (KIM-1), MDA ve SOD biyokimyasal olarak analiz edildi. p38 MAPK, PI3K/Akt sinyal yolaklarının aktivasyonu ve NFB p65 Western blot ile değerlendirildi. Bulgular: Parikalsitol, renal I/R süresince oluşan interstis- yel inflamasyonu anlamlı olarak azalttı. Bununla ilişkili olarak renal I/R süresince artan TNF-, IL-1, aktif kaspaz-3 ve KIM-1 parikalsitol ile anlamlı olarak azaldı. Parikalsitol ile aynı zamanda renal I/R süresince böbrek dokusunda artan MDA seviyesi anlamlı olarak azalırken, SOD aktivite düzeyi ise anlamlı olarak arttı. Ayrıca parikalsitolün renal I/R süresince artan p38 MAPK aktivasyonunu ve NFB p65 protein ifadesini baskılayabildiği ve PI3K/Akt sinyal ileti yolağını da aktive edebildiği saptandı. Sonuç: Tüm bu bulgular parikalsitol’ün renal I/R hasarına karşı geliştirilen stratejilerde aday olabileceğine işaret etmektedir.
