目的
2
探究木犀草素(luteolin,LTN)改善脓毒性心脏损伤的作用与机制。
方法
2
采用盲肠结扎穿孔术(caecal ligation perforation
CLP)建立小鼠脓毒症模型,将42只小鼠按随机数字表法分为3组:Sham组、CLP组和CLP+LTN组,每组14只。评估48 h生存情况,使用超声检测心脏功能,Western blot检测SIRT1、p-p65、p65的表达变化,PCR检测炎症因子mRNA表达水平。细胞实验中,使用1 μg/mL LPS处理小鼠巨噬细胞RAW 264.7 12 h,并取其培养基处理小鼠心肌细胞HL-1,加入不同浓度的LTN后,分别使用TNF-α ELISA试剂盒和CCK-8法确定最佳LTN处理浓度。敲低RAW 264.7和HL-1细胞SIRT1表达后,Western blot检测蛋白表达,PCR检测炎性因子mRNA水平,商用试剂盒检测ATP含量,CCK-8检测细胞活力。
结果
2
与Sham组相比,CLP组小鼠48 h生存率、心功能和SIRT1的表达明显降低(
P
<0.05),而p65的磷酸化水平(p-p65/p65),TNF-α、IL-1、IL-6的mRNA表达水平显著上升(
P
<0.05),但这些效应均可被LTN治疗抵消(
P
<0.05)。在RAW 264.7细胞中,LTN处理可以明显改善LPS引起的SIRT1的表达下降,以及p65磷酸化水平和IL-1、TNF-α、IL-6的mRNA表达水平升高(
P
<0.05),但SIRT1敲低则可抵消LTN的作用(
P
<0.05)。在HL-1细胞中,LTN处理可显著减少RAW 264.7+LPS培养基(RLM)处理引起的SIRT1表达、ATP含量和细胞活力下降(
P
<0.05),但该作用在敲低SIRT1后被部分消除(
P
<0.05)。
结论
2
LTN可通过激活SIRT1抑制炎症反应,提高心肌细胞抗炎作用,从而减少脓毒性心功能障碍。
Objective
2
To explore the effect and mechanism of luteolin (LTN) in sepsis-induced cardiac injury.
Methods
2
Caecal ligation perforation (CLP) was used to establish a septic model in mice
and 42 mice were randomly divided into Sham group
CLP group and CLP+LTN group
with 14 mice in each group. The 48-hour survival rate was observed. Ultrasonography was used to detect cardiac function
Western blotting was employed to detect the expression of SIRT1
p-p65 and p65
and PCR was applied to measure the mRNA levels of inflammatory cytokines. In
in vitro
study
LPS of 1 μg/mL was used to treat mouse macrophagocyte RAW 264.7
and then the medium was used to treat mouse cardiomyocytes HL-1. LPS-treated RAW 264.7 cells and RAW 264.7+LPS medium-treated HL-1 cells were co-cultured with different concentrations of LTN
and the optimal LTN concentration was determined by TNF-α ELISA kit and CCK-8 assay. Then after SIRT1 exp
ression of RAW 264.7 cells and HL-1 cells was knocked down by siRNA
the expression of above proteins was detected by Western blotting
and mRNA expression levels of inflammatory cytokines were measured by PCR
ATP content was detected by reagent kit
and cell viability was detected by CCK-8 assay.
Results
2
The mice of the CLP group had significantly lower 48-hour survival rate
cardiac function and SIRT1 expression (
P
<
0.05)
and increased protein level of p-p65/p65 and mRNA levels of IL-1
TNF-α and IL-6 (
P
<
0.05) when compared with the Sham group. However
these effects were reversed by LTN treatment (
P
<
0.05). In RAW 264.7 cells
LTN treatment significantly reversed LPS-induced decrease of SIRT1 expression
and increases in protein level of p-p65 and mRNA levels of IL-1
TNF-α and IL-6 (
P
<
0.05). Nevertheless
SIRT1 knockdown abolished the effect of LTN (
P
<
0.05). In HL-1 cells
LTN treatment significantly reversed the decrease of SIRT1 expression
ATP content and cell viability induced by RAW 264.7+LPS medium (
P
<
0.05)
but this effect could be partially eliminated by SIRT1 knockdown (
P
<
0.05).
Conclusion
2
LTN can inhibit inflammatory response and enhance the anti-inflammatory effect of cardiomyocytes by activating SIRT1
and thus reduce sepsis-induced cardiac dysfunction.
