It’s crucial to comprehend the impact of oxidative stress and
pro-inflammatory cytokines in the gentamicin-induced kidney injury mechanism.
Celecoxib was administered orally either before or after intraperitoneal therapy
with gentamicin in mice. The serum levels of creatinine (SCr), blood urea
nitrogen (BUN), IL-6, and TNF-α were measured by ELISA test, as well as
the levels of the kidney tissue malondialdehyde (MDA), and glutathione (GSH)
were also estimated spectrophotometrically. The renal expression of nuclear
factor-κB (NF-κB), interleukin-6 (IL-6), tumor necrosis
factor-α (TNF-α), and cyclooxygenase 2 (COX-2) mRNAs were
evaluated by qPCR. Histopathological evaluation and Immunohistochemical
examination of kidney NF-κB, IL-6, and COX-2 were also, performed.
Celecoxib successfully prevented gentamicin-induced kidney damage as indicated
by reducing blood BUN, SCr, and tissue MDA levels and increasing renal tissue
GSH levels as well as lowering the blood IL-6 and TNF-α in comparison to
mice received gentamicin. Furthermore, celecoxib has inhibited COX-2,
NF-κB, IL-6, and TNF-α expression in the renal tissue. It is
noteworthy that celecoxib therapy after gentamicin administration brought about
substantially the same results as celecoxib treatment before gentamicin
injection in mice. Our results showed the role of celecoxib as a therapeutic
tool for gentamicin-induced nephrotoxicity as well as raised its beneficial
prophylactic role in this medical challenge by attenuating oxidative stress and
inflammation.
