| Study Summary | Cisplatin-induced acute kidney injury (AKI) is a severe clinical complication with no satisfactory therapies in the clinic. Tumor necrosis factor receptor (TNFR)-associated factor 1 (TRAF1) plays an important role in both inflammation and metabolism. However, the role of TRAF1 in cisplatin-induced AKI needs to be evaluated. In this study, TRAF1 expression was decreased in cisplatin-treated mice and mouse proximal tubular cells (mPTCs), suggesting a potential role of TRAF1 in cisplatin-associated kidney injury. Thus, TRAF1 plasmids were introduced into male C57BL/6J mice by a tail vein high-pressure injection method to overexpress TRAF1. Then, cisplatin was administrated by a single intraperitoneal (i.p.) injection (20 mg/kg). Mice were sacrificed 72 h after cisplatin administration. Serum and kidney tissues were collected for further analysis. In vitro, mPTCs were transfected with TRAF1 plasmids before treatment with cisplatin (5 µg/mL) for 24 h. Western blotting, Masson’s trichrome and hematoxylin-eosin (HE) staining and tandem mass spectrometry (LC‒MS/MS) analysis were employed to evaluate kidney injury. Following cisplatin treatment, we observed a marked downregulation of TRAF1 in mouse kidneys and mPTCs treated with cisplatin. In mice, TRAF1 overexpression attenuated cisplatin-induced AKI, as evidenced by decreased levels of serum creatinine (Scr) and blood urea nitrogen (BUN). Moreover, TRAF1 delivery obviously ameliorated cisplatin-induced renal tubular injury, as shown by the improved histological damage and blocked upregulation of NGAL and KIM-1. Moreover, the NF-κB activation and inflammatory cytokine production enhanced by cisplatin were significantly blunted by TRAF1. In line with the attenuated inflammatory response, the increased number of apoptotic cells (TUNEL staining) and enhanced expression of BAX and cleaved Caspase-3 were markedly decreased by TRAF1 overexpression. In vitro, TRAF1 also attenuated renal tubular cell inflammation and apoptosis induced by cisplatin. In addition, disordered cellular metabolism, which was reported as an important pathogenic factor of AKI, was examined by metabolomics analysis. Interestingly, a significant correction of the metabolic disturbance, including perturbations in energy generation and lipid and amino acid metabolism, was observed in the kidneys of cisplatin-treated mice. In conclusion, TRAF1 overexpression significantly attenuated cisplatin-induced nephrotoxicity, possibly by correcting the impaired metabolism, inhibiting inflammation, and blocking apoptosis in renal tubular cells. |
