目的
2
从脑部基因组学探讨参附黄配方防治脓毒症相关性脑病的可能作用机制。
方法
2
C57BL/6小鼠随机分为假手术组、脓毒症组和参附黄组,每组20只。脓毒症组和参附黄组采取盲肠结扎穿孔术建立脓毒症小鼠模型。造模后4 h参附黄组小鼠给予参附黄溶液2.5 g/(kg·d)灌胃,每次0.5 ml,每隔12 h灌胃1次,造模后总共灌胃4次。假手术组和脓毒症组小鼠同时给予0.5 ml纯净水灌胃。造模48 h后利用转录组测序探究参附黄配方对脓毒症小鼠脑区影响的差异表达基因,运用Real-time PCR和ELISA法进一步验证差异表达基因及蛋白的表达。
结果
2
参附黄组与脓毒症组比较差异表达基因共4605个,其中2353个基因上调,2252个基因下调。结合既往文献结果,筛选出丝氨酸激酶(
Nek1
)
、
髓鞘相关糖蛋白
(Mag)、
内皮细胞特异性酪氨酸激酶受体(
Tek
)
、
血小板反应蛋白基序20的整合素和金属蛋白酶
(Adamts20)、
淋巴细胞抗原86
(Ly86)、
E3泛素蛋白连接酶
(Traip)
6个关键基因
。
进一步对基因及蛋白验证发现,与假手术组比较,脓毒症组小鼠脑组织
Nek1、Mag、Tek、Adamts20、Ly86、Traip
mRNA水平及相应蛋白水平均降低(
P
<0.05);与脓毒症组比较,参附黄组
Nek1、Mag、Tek、Adamts20、Ly86、Traip
mRNA水平及相应蛋白水平均升高(
P
<0.05)。
结论
2
参附黄配方防治脓毒症相关性脑病的可能作用潜在靶点与
Nek1、Mag、Tek、Adamts20、Ly86、Traip
基因及编码的蛋白有关。
Objective
2
To investigate the possible mechanism of
Shenfuhuang Formula
(参附黄配方) in prevention and treatment of epsis-associated encephalopathy from the perspective of brain genomics.
Methods
2
C57BL/6 mice were randomly divided into sham surgery group, sepsis group, and
Shenfuhuang
group, with 20 mice in each group. The sepsis group and
Shenfuhuang
group were induced to develop sepsis by cecal ligation and puncture (CLP) procedure. At 4 hours after mod
elling,
Shenfuhuang
group were gavaged with 2.5 g/(kg·d) of
Shenfuhuang Formula
, 0.5 ml each time, at 12 hours intervals, for a total of 4 times after modelling. Sepsis group and sham surgery group were given 0.5 ml of purified water orally. At 48 hours after modeling, the transcriptome sequencing was used to explore the differential gene expression in the effects of
Shenfuhuang Formula
on the brain regions of septic mice, and real-time PCR and ELISA were later used to further validate the differential gene and proteins expression.
Results
2
A total of 4605 genes were differentially expressed in
Shenfuhuang
group compared with sepsis group, of which 2353 genes were up-regulated and 2252 genes were down-regulated. According to the results of previous publications, six key genes were screened, including serine/threonine-protein kinase (
Nek1
), myelin-associated glycoprotein (
Mag
), endothelial cell-specific tyrosine kinase receptor (
Tek
), a disintegrin and metalloproteinase with thrombospondin motifs 20 (
Adamts20
), lymphocyte antigen 86 (
Ly86
), and E3 ubiquitin-protein ligase (
Traip
). Further genetic and protein validation revealed that, compared to the sham surgery group, the mRNA levels and corresponding protein levels of
Nek1
,
Mag
,
Tek
,
Adamts20
,
Ly86
, and
Traip
in the brain tissue of septic mice significantly reduced (
P
<0.05). In comparison to the sepsis group,
Shenfuhuang
group showed significantly increased mRNA levels and corresponding protein levels of
Nek1
,
Mag
,
Tek
,
Adamts20
,
Ly86
, and
Traip
(
P
<0.05).
Conclusion
2
The potential thera
peutic targets of
Shenfuhuang Formula
for treating sepsis-associated encephalopathy may be related to the
Nek1
,
Mag
,
Tek
,
Adamts20
,
Ly86
, and
Traip
genes and their encoded proteins.
