ABSTRACT
Acute kidney injury (AKI) is commonly encountered and causes high mortality in hospitalized patients; however, effective therapies for AKI have still not been established. Accordingly, we performed a rodent model with acute renal ischemia-reperfusion (IR) and tested the hypothesis that combined tacrolimus and melatonin therapy could be superior to either one for protecting the kidney against IR injury. Adult-male SD rat (n = 30) were equally categorized into group 1 (receiving laparotomy only), group 2 (IR treated by 3.0 cc/normal-saline), group 3 [IR + tacrolimus/0.5 mg/kg by intravenous administration at 30 minutes and at days 1/2/3 after IR], group 4 (IR + melatonin/50 mg/kg by intra-peritoneal administration at 30 minutes and 25 mg/kg at days 1/2/3 after IR] and group 5 (IR + tacrolimus +melatonin). By day 3 after IR, the creatinine/BUN levels and ratio of urine protein to urine creatinine were highest in group 2, lowest in group 1 and significantly lower in group 5 than in groups 3/4 (all P < .0001), but they did not differ between the groups 3/4. The protein expressions of oxidative-stress (p47phox/NOX-1/NOX-2/NOX-4), upstream (TLR4/MAL/MyD88/TRAF6/ASK1/MKK4/MKK7/NF-κB) and downstream (IL-6/INF-γ/MMP-9/IL-1ß) inflammatory signaling, MAPK-family-signaling cascades(ERK1/2, JNK/p38/c-JUN), apoptotic/autophagic (p53/caspase 3/mitochondrial-Bax, ratio of LC3B-II/LC3B-I), and mitochondrial-damaged (cyclophilin D/cytochrome C/DRP1) biomarkers, and the expressions of inflammatory-immune cells (F4/80, CD14/CD3/CD8) as well as the kidney injured score exhibited an identical pattern of creatinine level (all P < .0001). In conclusion, combined tacrolimus and melatonin therapy was better than either single one on protecting the kidney functional and anatomical integrity against IR injury through suppressing inflammation and the generation of oxidative stress.
