Abstract:
The attenuation of cisplatin-induced acute kidney injury (AKI) in mice by N-(2-hydroxyphenyl) acetamide
(NA-2) and NA-2-conjugated gold nanoparticles (NA2-AuNPs) was investigated. Male BALB/c mice (n = 54) were
divided into nine groups having six animals in each group. Animals in groups 3-9 were pre-treated for 5 days with test
compounds, whereas, animals in group 1 and 2 received normal saline. On day 4, animals in groups 2, 3, 4, 5, 6 and 9
were given single intra-peritoneal injection of CP at the dose of 5 mg/kg. After 72 hours of CP injection, all animals
were sacrificed. Blood was collected for serum urea and creatinine estimation, and kidneys were harvested for histopathological examinations and qPCR studies for nuclear factor-κB p50, (NFκB) ; inducible nitric oxide synthase (iNOS);
hemeoxygenase-1 (HO-1); and interleukin-6 (IL-6).NA-2 and NA2-AuNPs was observed to decrease the serum urea and
creatinine levels. Both the test compounds reduced kidney injury damage score and improved histological architecture in
the treated animals in dose dependent manner. Furthermore, the mRNA expressions of NFkB p50, iNOS and IL-6 genes
were down-regulated, and HO-1 gene was up-regulated in the animals treated with the test compounds. It is concluded
that NA-2 and NA2-AuNPs attenuates CP-induced AKI in mice models through anti-inflammatory and anti-oxidant
mechanisms.
