Cisplatin is a chemotherapeutic agent that widely used in the treatment of cancer. However, cisplatin has been reported to induce nephrotoxicity by directly inducing inflammatory response and oxidative stress. In this study, we aimed to investigate the protective effects and mechanism of xanthohumol on cisplatin-induced nephrotoxicity. The model of nephrotoxicity was induced by intraperitoneal injection of cisplatin and xanthohumol was given intraperitoneally for three consecutive days. The results showed that xanthohumol significantly attenuated kidney histological changes and serum creatinine and BUN production. The levels of TNF-α, IL-1ß and IL-6 in kidney tissues were suppressed by xanthohumol. The levels of malondialdehyde (MDA) and ROS were suppressed by treatment of xanthohumol. The activities of glutathione (GSH) and superoxide dismutase (SOD) decreased by cisplatin were reversed by xanthohumol. Furthermore, the expression of TLR4 and the activation of NF-κB induced by cisplatin were significantly inhibited by xanthohumol. The expression of Nrf2 and HO-1 were dose-dependently up-regulated by the treatment of xanthohumol. In conclusion, xanthohumol protects against cisplatin-induced nephrotoxicity by ameliorating inflammatory and oxidative responses.

Cisplatin-induced nephrotoxicity, a major limitation of this chemotherapeutic agent, involves oxidative stress, inflammation, and apoptosis. This study investigated the potential renoprotective effects of humic acid in a rat model of cisplatin-induced nephrotoxicity. Forty-two male Wistar rats were assigned to six groups: control, humic acid, cisplatin, cisplatin + humic acid 10 mg/kg, cisplatin + humic acid 20 mg/kg, and cisplatin + humic acid 40 mg/kg.

The incidence rate and mortality rate of breast cancer remain high, and there is an urgent need for safe and effective drugs. The excellent biological activity of hesperidin (HE) is a potential drug for the treatment of breast cancer. In this study, silk fibroin peptides (SFP) were used as delivery carriers and HE loaded SFP nanofibers (SFP/HE NFs) was prepared.

Background: Cisplatin is an anti-cancer drug used to treat a plethora of solid tumors. However, it is associated with dose dependent nephrotoxicity limiting its use as anticancer agent.
Objective: The current study aimed to investigate the nephroprotective effect of native Lebanese Cannabis sativa in both in vitro and in vivo mice model of cisplatin-induced nephrotoxicity.
Efficacy and Safety of Short Intravenous Hydration for Preventing Nephrotoxicity From High-Dose Cisplatin: A Randomized, Open-Label, Phase II Trial.

Purpose: The use of short hydration (SH) to prevent cisplatin-induced nephrotoxicity lacks substantive prospective evaluation. The aim of this study was to evaluate the safety and efficacy of SH, including those with head and neck cancer (HNC) who are at higher risks of mucositis that causes diminished oral intake.
Methods: This phase II randomized noncomparative trial included patients with cancer who were scheduled to receive high-dose cisplatin (≥60 mg/m) in combination with another chemotherapy or concurrently with radiotherapy.
Methylcrotonyl-CoA carboxylase 2 supports leucine catabolism to promote mitochondrial biogenesis and alleviate cisplatin-induced acute kidney injury.

Background: Cisplatin is widely used in clinical practice, but its nephrotoxicity severely limits its use. Previous studies have shown that cisplatin-induced acute kidney injury (AKI) is closely related to mitochondrial damage and that alleviating mitochondrial dysfunction can alleviate cisplatin-induced AKI. Methylcrotonyl‑CoA carboxylase 2 (MCCC2) is mainly located in mitochondria, where it catalyzes the catabolism of leucine and maintains mitochondrial function; however, the role of MCCC2 in cisplatin-induced renal injury has not yet been studied.
