The aim of the present study is to analyze the effects of 5-aminoisoquinoline
(5-AIQ), a poly(ADP-ribose) polymerase-1 (PARP1) inhibitor, over renal
dysfunction and fibrosis during recovery phase of cisplatin (CisPt)-induced acute
kidney injury (AKI) in rats. Male Wistar rats were distributed in three groups
(n=8 each group): control, CisPt, and CisPt + 5-AIQ. Control and CisPt groups
received a subcutaneous injection of either saline or 7 mg/kg CisPt,
respectively. CisPt + 5-AIQ group received two intraperitoneal injections of 10
mg/kg 5-AIQ 2 h before and 24 h after CisPt treatment. Thirteen days after the
treatment, rats were housed in metabolic cages and 24-h urine collection was
made. At day 14, CisPt-treated rats showed increased diuresis,
N-acetyl-?-d-glucosaminidase (NAG) excretion, glucosuria and sodium fractional
excretion (NaFE), and decreased creatinine clearance (CrCl). 5-AIQ significantly
increased CrCl and decreased NAG excretion, glucosuria, and NaFE. In plasma,
CisPt increased sodium, urea, and creatinine concentrations, while 5-AIQ
treatment decreased these variables to the levels of control group. 5-AIQ
completely prevented the body weight loss evoked by CisPt treatment. CisPt also
induced an increased renal expression of PAR polymer, ?-smooth muscle actin
(?-SMA), transforming growth factor-?1 (TGF-?1), and collagen-IV. These variables
were decreased in CisPt + 5-AIQ group. Tubular lesions and renal fibrosis were
also decreased by 5-AIQ treatment. We conclude that inhibition of PARP1 with
5-AIQ can attenuate long-term nephrotoxic effects associated with the CisPt
treatment, preventing renal dysfunction and body weight decrease and ameliorating
tubular lesions and collagen deposition.
