Effect of Ficus carica L. leaves extract loaded gold nanoparticles against cisplatin-induced acute kidney injury.

BACKGROUND

Cisplatin (CisPt) is one of the most widely used and highly effective drugs for the treatment of various solid tumors, unfortunately acute kidney injury (AKI) is considered one of its side effects through several mechanisms including production of reactive oxygen species (ROS), pro-inflammatory and pro-fibrotic cytokines. Due to the poor effect of AKI therapy, the use of nanoparticles loaded with natural extracts for delivering to the kidney molecules are desirable.

AIM: This study aims to investigate the effectiveness of different concentrations of gold nanoparticles (Au-NPs) as a carrier for Ficus carica L. (Fig) leaves extract against CisPt induced AKI.

METHODS

Seventy male albino rats were used and divided into seven groups. After the experimental period, blood was withdrawn, serum was separated for determination of urea, creatinine, homocystein (Hcy) and folic acid while reduced glutathione (GSH), nitric oxide (NO), malondialdehyde (MDA), total antioxidant capacity (TAC) and hydroxyproline content (Hyp) were evaluated in kidney tissue homogenate.

RESULTS

CisPt induced AKI in rats and results in a significant increase in the levels of serum urea, creatinine, Hcy and kidney Hyp, lipid peroxidation along with a significant reduction of kidney GSH, NO and TAC compared to the control rats. Treatment with Au-NPs and Fig extract particularly in a ratio of (3:2) respectively was shown to improve renal functions with efficient capacity in scavenging ROS and reduced AKI severity.

CONCLUSION

Au-NPs enhanced the anti-oxidative properties of the Fig extract in targeting kidney damaged tissue and reduced oxidative toxicity induced by CisPt.
