ABSTRACT: Background: Green coffee as a functional food has an antioxidant effect, which can reduce the cancer incidence, promote weight-loss and improve glucose and lipid metabolism, as well as anti-oxidant and anti-inflammatory activity. Objective: Assessing the effect of green coffee administration on experimental cisplatin induced renal apoptosis in adult male albino rats of local strain. Design: Randomized Block Design was used. Materials and Methods: Forty adult male albino rats of local strain were randomly divided into four groups of 10 animals each. G1: control negative group was received isotonic saline (0.5 ml, i.p.) for 30 consecutive days, G2: sham operated group mice were received green coffee extract in water (40 mg/kg/day) for 30 consecutive days, animals of G3 and G4 were administered cisplatin (8 mg/kg/day, i.p.) at 10th day, which is well known to produce significant nephrotoxicity in rats. Animals in G3 were received green coffee extract in water (40 mg/kg/day) and G4 was received isotonic normal saline (0.5 ml, i.p.) for 30 consecutive days. All rats were sacrificed after 30 days and blood was withdrawn for biochemical examinations of kidney function tests (blood urea nitrogen, creatinine and uric acid). Kidneys were removed for determination of renal oxidative stress markers (H2O2) biochemically and caspase-3 by Immunohistochemical examination. Results: Cisplatin administration was associated with significant higher levels of BUN, creatinine, uric acid and H2O2 as compared with normal control group. Green coffee administration in cisplatin-induced renal apoptosis groups produced significant lower levels of BUN, creatinine, uric acid and H2O2 (24.4 ± 4.14, 1.730 ± 0.2830, 5.50 ± 0.850 and 0.51 ± 0.12 respectively) as compared with cisplatin-induced renal apoptosis group not administrated green coffee (27.4 ± 6, 2.04 ± .31, 7.00 ± 1.25 and 1.1 ± 0.16 respectively). Cisplatin administration increased expression of the apoptotic protein caspase-3. In contrast, treatment with green coffee extract attenuated apoptosis. Conclusion: green coffee reduced cisplatin-induced renal apoptosis. Green coffee improved the general condition of cisplatin-induced renal apoptosis rats due to its antioxidant and anti-apoptotic effects.
