By establishing mouse models, the study found that aspirin can alleviate cisplatin-induced acute kidney injury, and its protective mechanisms are related to its anti-inflammatory, antioxidant, anti-apoptotic properties, and its ability to maintain mitochondrial function, mainly achieved through the activation of the AMPK-PGC-1 alpha pathway.
Cisplatin (CIS) is a widely used clinical chemotherapeutic agent for solid malignancies such as lung, testicular and ovarian cancers, but the development of nephrotoxicity has limited the use of this class of drugs. Some studies have shown that aspirin can reduce cisplatin-induced nephrotoxicity, but the mechanism of protection is not yet clear. By establishing a mouse model of cisplatin-induced acute kidney injury and a mouse model of aspirin combination, we observed a reduction in creatinine, blood urea nitrogen, and tissue damage, thus verifying that aspirin can alleviate cisplatin-induced acute kidney injury in mice. Aspirin was found to have a significant protective effect against cisplatin-induced acute kidney injury, as evidenced by the reduction in levels of ROS, NO, and MDA and the increase in T-AOC, CAT, SOD, and GSH. Furthermore, aspirin was observed to down-regulate the expression of pro-inflammatory factors TNF-alpha, NF-kappa B, IL-1 beta, and IL-6 mRNA and proteins, increase the expression of BAX and Caspase3 as indicators of apoptosis, decrease the expression of Bcl-2, and improve the reduced expression of mtDNA, ATP content, ATPase activity and mitochondrial respiratory chain complex enzyme-related genes ND1, Atp5b, and SDHD. These findings suggest that the protective effects of aspirin are associated with its anti-inflammatory, antioxidant, anti-apoptotic properties, and its ability to maintain mitochondrial function, as demonstrated by the detection of AMPK-PGC-1 alpha pathway-related genes. The results showed that the reduced expression of p-AMPK and mitochondrial production-related mRNA PGC-1 alpha, NRF1, and TFAM in the kidney tissue of mice in the cisplatin group was alleviated by the effect of aspirin, indicating that aspirin could activate the p-AMPK, regulate mitochondrial production and alleviate cisplatin acute kidney injury through the AMPK-PGC-1 alpha pathway. In summary, certain doses of aspirin protect the body from acute kidney injury by alleviating the cisplatin-induced inflammatory response oxidative stress, mitochondrial dysfunction, and apoptosis. Further studies have shown that the protective effect of aspirin is associated with AMPK-PGC-1 alpha pathway activation.
