目的
2
基于沉默信息调节因子2同源蛋白1/过氧化物酶体增殖物激活受体γ辅激活因子1α(Sirt1/PGC-1α)通路探究茯苓酸对妊娠高血压(PIH)大鼠肾损伤的作用机制。
方法
2
SD大鼠雌雄合笼喂养制备孕鼠,并通过腹腔注射
N
-硝基-左旋精氨酸甲酯构建PIH大鼠模型。将PIH大鼠分为模型组、低-茯苓酸(低剂量茯苓酸,10 mg/kg)组、高-茯苓酸(高剂量茯苓酸,20 mg/kg)组、高-茯苓酸+EX527(20 mg/kg茯苓酸+10 mg/kg EX527)组,每组6只。另取6只正常孕鼠为空白组。各组孕鼠每日灌胃或腹腔注射相应药物或溶剂,每日1次,连续28 d。末次给药后,检测各组孕鼠24 h尿蛋白和尾动脉收缩压(SBP),血清中血肌酐(Scr)、尿素氮(BUN)、尿酸(UA)、胱抑素C(Cys-C)水平,
肾组织中超氧化物歧化酶(SOD)、丙二醛(MDA)、谷胱甘肽过氧化物酶(GSH-Px)、8-羟基脱氧鸟苷(8-OHdG)含量以及Sirt1、PGC-1α mRNA及蛋白表达水平;同时,通过苏木精-伊红(HE)染色和过碘酸-雪夫染色(PAS)染色评估各组大鼠肾组织病理学变化。
结果
2
与模型组比较,低-茯苓酸组和高-茯苓酸组大鼠24 h尿蛋白,尾动脉SBP,血清中Scr、BUN、UA、Cys-C水平,肾小球硬化指数评分,肾小管损伤评分,肾组织PAS阳性面积百分比及MDA、8-OHdG含量均显著降低(
P
<0.05),SOD、GSH-Px含量和Sirt1、PGC-1α mRNA及蛋白表达水平均显著升高(
P
<0.05),且高-茯苓酸组变化更明显(
P
<0.05);与高-茯苓酸组比较,高-茯苓酸+EX527组孕鼠上述指标变化均显著逆转(
P
<0.05)。
结论
2
茯苓酸可通过激活Sirt1/PGC-1α通路改善PIH诱导的孕鼠肾损伤。
OBJECTIVE
2
To investigate the mechanism of pachymic acid on renal injury in pregnancy induced hypertension (PIH) rats by regulating the silent information regulator transcript 1/peroxisome proliferator-activated receptor γ coactivator-1α (Sirt1/PGC-1α) pathway.
METHODS
2
Pregnant SD rats were prepared by co-caging and PIH model was induced using
N
-nitro-L-arginine methyl ester (L-NAME) method. PIH rats were randomly divided into model group, L-pachymic acid (low-dose pachymic acid, 10 mg/kg) group, H-pachymic acid (high-dose pachymic acid, 20 mg/kg) group, and H-pachymic acid+EX527 (20 mg/kg pachymic acid+10 mg/kg EX527) group, with 6 rats in each group. Another 6 normal pregnant rats were selected as blank group. Each group was given relevant medicine or solvent intragastrically or intraperitoneally daily, once a day, for 28 consecutive days. After the last administration, 24 h urinary protein and tail artery systolic blood pressure (SBP) were measured in pregnant rats from each group, along with the levels of serum creatinine (Scr), blood urea nitrogen (BUN), uric acid (UA), and cystatin C (Cys-C). The contents of superoxide dismutase (SOD), malondialdehyde (MDA), glutathione peroxidase (GSH-Px), and 8-hydroxy-2′-deoxyguanosine (8-OHdG) in renal tissue, as well as the mRNA and protein expression levels of Sirt1 and PGC-1α, were also de
termined. Meanwhile, renal histopathological changes in rats from each group were evaluated using hematoxylin-eosin (HE) staining and periodic acid-Schiff (PAS) staining.
RESULTS
2
Compared with model group, L-pachymic acid group and H-pachymic acid group exhibited significant decreases in 24 h urine protein quantification, tail artery SBP, Scr, BUN, UA, Cys-C levels, glomerulosclerosis index score of renal tissue, renal tubular injury score, the percentage of PAS positive area, MDA and 8-OHdG (
P
<0.05). Conversely, the contents of SOD and GSH-Px, along with the mRNA and protein expression levels of Sirt1 and PGC-1α, were significantly increased (
P
<0.05). Moreover, these improvements were more pronounced in H-pachymic acid group (
P
<0.05). Compared with H-pachymic acid group, the aforementioned indicators in pregnant rats from the H-pachymic acid+EX527 group showed significant reversal (
P
<0.05).
CONCLUSIONS
2
Pachymic acid significantly ameliorates renal injury induced by PIH in rats, potentially through activation of the Sirt1/PGC-1α pathway.
