PG - 4756846 LID - 10.1155/2018/4756846 [doi] LID - 4756846 AB - Sepsis-induced acute kidney injury (AKI) is a severe complication of sepsis and an important cause of mortality in septic patients. Previous investigations showed that methane had protective properties against different diseases in animal models. This study is aimed at investigating whether methane-rich saline (MRS) has a protective effect against sepsis-induced AKI. Sepsis was induced in wild-type C57BL/6 mice by cecal ligation and puncture (CLP), and the mice were divided into three groups: a sham control group (sham), a surgery group with saline intraperitoneal injection (i.p.) treatment (CLP + NS), and a surgery group with MRS i.p. treatment (CLP + MRS). 24 h after the establishment of the sepsis, the blood and kidney tissues of mice in all groups were collected. According to the serum levels of blood urea nitrogen (BUN) and creatinine (CRE) and a histologic analysis, which included hematoxylin-eosin (H&E) staining and periodic acid-Schiff (PAS) staining, MRS treatment protected renal function and tissues from acute injury. Additionally, MRS treatment significantly ameliorated apoptosis, based on the levels of apoptosis-related protein makers, including cleaved caspase-3 and cleaved PARP, and the levels of Bcl-2/Bax expression and TUNEL staining. In addition, the endoplasmic reticulum (ER) stress-related glucose-regulated protein 78 (GRP78)/activating transcription factor 4 (ATF4)/C/EBP homologous protein (CHOP)/caspase-12 apoptosis signaling pathway was significantly suppressed in the CLP + MRS group. The levels of inflammation and oxidative stress were also reduced after MRS treatment. These results showed that MRS has the potential to ameliorate sepsis-induced acute kidney injury through its anti-inflammatory, antioxidative, and antiapoptosis properties.
