Kidney Injury

Endoplasmic reticulum stress (ERS) is strongly associated with acute kidney injury (AKI) to chronic kidney disease (CKD) transition. Huaier extract (HE) protects against kidney injury; albeit, the underlying mechanism is unknown. We hypothesized that HE reduces kidney injury by inhibiting ERS. In this study, using an AKI-CKD mouse model of ischemia-reperfusion injury (IRI), we evaluated the effect of HE on AKI-CKD transition. We also explored the underlying molecular mechanisms in this animal model and in the HK-2 human kidney cell line. The results showed that HE treatment improved the renal function, demonstrated by a significant decrease in serum creatinine levels after IRI. HE appreciably reduced the degree of kidney injury and fibrosis and restored the expression of the microRNA miR-1271 after IRI. Furthermore, HE reduced the expression of ERS markers glucose-regulated protein 78 (GRP78) and C/EBP homologous protein (CHOP) and inhibited apoptosis in the IRI group. This in vivo effect was supported by in vitro results in which HE inhibited apoptosis and decreased the expression of CHOP and GRP78 induced by ERS. We demonstrated that CHOP is a target of miR-1271. In conclusion, HE reduces kidney injury, probably by inhibiting apoptosis and decreasing the expression of GRP78 and CHOP via miR-1271 upregulation.

The Impact

Objective: We analyzed the influence of N-acetylcysteine (NAC) in chronic kidney disease (CKD) rats on the plasma concentration of lipid peroxides (TBARS) and advanced glycation end products (AGE) and on the impact of serum CKD-albumin in the development of macrophage endoplasmic reticulum stress (ERS). Methods: CKD was induced by 5/6 nephrectomy in 2-month old male Wistar rats. Controls (C) were sham operated. Animals were treated or not with NAC (600mg/L of water). FPLC isolated serum albumin was purified by alchoolic extraction. J774 macrophages were incubated with serum albumin (1mg/mL; 18h) from all groups, and the expression of ERS markers (protein disulfide isomerase - PDI and Grp94 chaperone) determined by immunoblot. Comparisons were done by one-way ANOVA, Student t test. Results: After 60 days of CKD, body weight was 10% lower in CKD compared to C (p<0.01). This was prevented by NAC. Urea, creatinine, total cholesterol (TC), triglycerides (TG) (mg/dL), urinary protein excretion (mg/24h) (C, n= 31; C+NAC, n=20; CKD, n=74; CKD+NAC, n=32), total AGE and pentosidine (n= 8; fluorescence arbitrary unit) and TBARS (n= 7; nmoL/mL) were higher in CKD (122±8; 0.9±0.07; 151±6; 83±4; 46±2.5; 32620±673; 16700±1370; 6.6±0.5, respectively) and in CKD+NAC (91.4±5; 0.6±0.02; 126±7.5; 73±6; 51±3.5; 24,720±1,114; 10,080±748; 4.5±0.5, respectively) in comparison to C (41±0.9; 0.4±0.03; 76±2.7; 51.5±3; 14±0.9; 21,750±960; 5,314±129; 2±0.2, respectively; p<0.001) and C+NAC (40±0.9; 0.3±0.02; 76±2.6; 68±4; 18.4±1.5; 20,040±700; 5,050±267; 1.8±0.2, respectively; p<0,001). TC, urea, creatinine, total AGE, pentosidine and TBARS were respectively, 17%, 25%, 33%, 24%, 40% and 28% (p<0.01) lower in CKD+NAC, than in CKD. Glycemia was higher in C+NAC (107±4.6) and CKD+NAC (107±2.6) than in C (96±1.8; p<0.05) and CKD (98±1.6; p<0.01), respectively. In macrophages (n=6), CKD albumin increased PDI (5 and 7 times, p<0.01) and Grp94 (66% and 80%, p<0.01) in comparison to C and CKD+NAC-albumin treated cells, respectively. Conclusion: NAC reduces plasma lipid peroxidation and AGE and abrogates ERS induced by CKD-albumin. This may contribute to attenuate the deleterious effects of CKD-albumin on lipid accumulation in macrophages helping preventing atherogenesis in CKD.
