Abstract

PURPOSE

To explore the role of all-trans retinoic acid (ATRA) in renal ischemia/reperfusion injury of diabetic rats.

METHODS

Sixty adult male rats were randomly divided into 6 groups, including sham group (S group), ischemia-reperfusion group (I/R group), ischemia-reperfusion+ATRA group (A group), diabetic group (D group), diabetic ischemia-reperfusion group (DI/R group), diabetic ischemia-reperfusion +ATRA group (DA group). The levels of creatinine (Cr), cystatin C (Cys-C) and β2-microglobulin (β2-MG) were measured. Morphology of renal tissue was observed under light microscope.

RESULTS

DJ-1, Nrf2, HO-1 and caspase-3 were detected by western blot. DJ-1, Nrf2, HO-1 and caspase-3 in I/R group, D group and DI/R group was higher than that in S group. Compared with I/R group, Nrf2 and HO-1 in A group was decreased, but caspase-3 was increased. However, Nrf2 in DA group was higher than that in DI/R group, HO-1 and caspase-3 in DA group were lower than that in DI/R group. Compared with group S, Cr, Cys-C and β2-MG in I/R group, A group, D group, and DI/R group were higher. Whereas the levels of Cr, Cys-C, β2-MG and renal injury score in DA group were lower than those in DI/R group.

CONCLUSION

ATRA has a protective effect on renal ischemia-reperfusion injury in diabetic rats, maybe relating to DJ/Nrf2 pathway.

摘要

目的

探讨全反式维甲酸（ATRA）在糖尿病大鼠肾脏缺血/再灌注损伤中的作用。

方法

将60只成年雄性大鼠随机分为6组，包括假手术组（S组）、缺血-再灌注组（I/R组）、缺血-再灌注+ATRA组（A组）、糖尿病组（D组）、糖尿病缺血-再灌注组（DI/R组）、糖尿病缺血-再灌注+ATRA组（DA组）。检测肌酐（Cr）、胱抑素C（Cys-C）和β2-微球蛋白（β2-MG）水平。在光学显微镜下观察肾组织形态。

结果

通过蛋白质印迹法检测DJ-1、Nrf2、HO-1和caspase-3。I/R组、D组和DI/R组中的DJ-1、Nrf2、HO-1和caspase-3高于S组。与I/R组相比，A组中的Nrf2和HO-1降低，但caspase-3升高。然而，DA组中的Nrf2高于DI/R组，DA组中的HO-1和caspase-3低于DI/R组。与S组相比，I/R组、A组、D组和DI/R组中的Cr、Cys-C和β2-MG更高。而DA组中的Cr、Cys-C、β2-MG水平和肾损伤评分低于DI/R组。

结论

ATRA对糖尿病大鼠肾脏缺血-再灌注损伤具有保护作用，可能与DJ/Nrf2通路有关。
