反式脂肪酸通過SIRT1/PGC1-α/Nrf2信號通路介導(dǎo)的大鼠血管損傷
發(fā)布時間:2021-07-03 18:24
目的:本次研究主要致力于觀察攝入低劑量反式脂肪酸是否會對血管造成損傷及其可能的機(jī)制。方法:8周齡清潔級SD大鼠48只,雌雄各半。大鼠適應(yīng)性喂養(yǎng)一周,遵從隨機(jī)、均衡原則,隨機(jī)分為3組:(1)對照組(ND);(2)1%TFA飲食組(LTD);(3)4%TFA飲食組(HTD),每組16只,自由進(jìn)食、進(jìn)水,雌雄分籠,飼養(yǎng)12周。實驗期間每周測量體重及進(jìn)食量,并定期測量血壓。連續(xù)喂養(yǎng)12周后,斷頭處死,收集血液,分離血清用于血脂檢測。分離出大鼠的血管組織,其中每組6只用于做病理學(xué)切片,觀察血管形態(tài)學(xué)變化,每組取3只用于檢測血管組織內(nèi)ROS生成情況,余下血管組織采用Western blot法測定大鼠血管組織SIRT1、PGC1-α、PPARγ、NOX4、Nrf2、Bcl-2、Bax、caspase3和cleaved-caspase3蛋白的表達(dá)量。數(shù)據(jù)以`x±SD表示,多組間比較采用SPSS 20.0軟件對數(shù)據(jù)進(jìn)行One-way ANOVA檢驗,P<0.05為差異有統(tǒng)計學(xué)意義。結(jié)果:1.實驗結(jié)束時,各組大鼠體重及進(jìn)食量均隨年齡增加而增加,且各組間無統(tǒng)計學(xué)差異(P>0.05)。各組大鼠于0...
