Abstract(s) :

(Anglais) Context: Acute kidney injury (AKI) is often encountered in patients receiving cisplatin (CisPt), a chemotherapeutic drug that induces numerous toxic side effects. Techniques used to limit nephrotoxicity during CisPt treatment are not fully effective; about a third of patients experience AKI. New nephroprotective strategies, including pharmacological approaches, must be developed. Objective: The present study investigated the nephroprotective potential of Angelica sinensis (Oliv.) Diels (Apiaceae) root towards CisPt tubulotoxicity. Materials and methods: HK-2 cells were incubated with CisPt (10 mM) and/or with a methanolic extract of A. sinensis (AS). Nephroprotective capacity was evaluated by means of cellular viability (resazurin assay) and apoptosis (annexin-V/PI staining), oxidative stress generation (H2DCF-DA oxidation), Ki-67 index (immunofluorescence), cell cycle analysis (DNA staining), cell migration rate (scratch assay), extracellular matrix deposition (collagen determination), and b-catenin relocalization. Results: CisPt decreased cell viability [76% versus Ctrl], which was associated with an increased apoptosis. Simultaneous treatment with 50 mg/ml AS enhanced cell survival [84% versus Ctrl] and decreased the apoptosis rate. AS could not alleviate CisPt-induced oxidative stress; but doses of 5 and 50 mg/ml raised the Ki-67 index [135 and 244% versus Ctrl] and cell migration rates [1.2 and 1.3-fold versus Ctrl]. Finally, both doses of AS limited the amount of collagen deposition [121.6 and 119.6% for 5 and 50 mg/ml, respectively, versus 131.0% for CisPt-treated cells] and prevented the relocalization of b-catenin from the membrane to the nucleus. Conclusion: These results confirm the nephroprotective potential of A. sinensis and require further investigations aiming at identifying its active compounds.
