The effects of Shenqi Wan on renal damage, GRP78, and autophagy-related factors in Zucker diabetic fatty rats
20只雄性8周龄ZDF大鼠给予5C08高脂饲料诱导4周后,随意分为模型组与肾气丸组,7只同周龄雄性Zucker瘦型大鼠为对照组。肾气丸组大鼠每日灌服肾气丸水煎液(8.12 g/kg),模型组和对照组大鼠每日灌服等量生理盐水,连续给药4周。观察大鼠一般情况并检测空腹血糖(FBG)与24 h尿微量白蛋白(24 h U-mAlb);观察肾组织病理变化;实时荧光PCR和蛋白质印迹法分别检测肾组织GRP78、Beclin-1和LC3的基因与蛋白表达。
on renal damage in Zucker diabetic fatty (ZDF) rats and the underlying mechanisms.
Methods
2
Twenty 8-week-old male ZDF rats were given 5C08 high-fat fodder for four weeks to induce diabetes. ZDF rats were randomly divided into the model group and the
Shenqi Wan
group. Seven male Zucker lean rats of the same age were used as the control group. Rats in the
Shenqi Wan
group were given
Shenqi Wan
decoction (8.12 g/kg). Rats in the model group and the control group were given the same amount of normal saline. Rats were continuously administered for 4 weeks. The general condition of rats was observed regularly. The fasting blood glucose (FBG) and 24-hour urinary microalbumin (24 h U-mAlb) levels were measured. Renal tissue was stained and morphology was observed. The ultra-microstructure was observed by transmission electron microscopy. The mRNA levels of GRP78
Beclin-1
and LC3 in rat renal tissue were examined by real-time PCR and the protein levels were examined by Western blotting.
Results
2
Compared with the model group
rats in the
Shenqi Wan
group showed improved fur gloss
more weight increase(
P
<
0.05); both FBG and 24 h U-mAlb levels were decreased (
P
<
0.05). The kidneys of rats in the model group showed dilated glomerular capillaries
irregularly thickened basement membranes
widened mesangial areas
and segmental sclerosis; renal tubular atrophy and renal interstitial fibrous tissue were also observed in these kidneys. These pathological changes were alleviated in the
Shenqi Wan
group. Compared with the model group
both gene and protein levels of GRP78 were decreased (
P
<
0.05) in the
Shenqi Wan
group; the protein level of Beclin-1 was decreased (
P
<
0.05); and the protein level of LC3 was increased (
P
<
0.05).
Conclusion
2
Shenqi Wan
may alleviate renal damage in ZDF rats with type 2 diabetes mellitus and delay the progression of diabetic kidney disease by reducing endoplasmic reticulum stress and enhancing autophagy.
