Mechanism of Guhong Injection Against Cerebral Ischemia Based on Transcriptome Analysis
Based on the protective effect of Guhong injection (GH) on cerebral ischemia
mechanism of GH against cerebral ischemia was identified using RNA-seq transcriptome and bioinformation analysis.
Method:
2
The model of middle cerebral artery occlusion (MCAO) was established through thread embolization. Sham group
model group
low-dose GH group (0.625 mL·kg
-1
·d
-1
)
high-dose GH group (2.5 mL·kg
-1
·d
-1
)
positive group (Ginaton
8 mL·kg
-1
·d
-1
) were set up. Ludmila Belayev 12-point scoring method was applied to assess the protective effect of GH against MCAO-induced cerebral ischemia. And the differentially expressed genes after treatment with GH were identified by RNA-Seq technology. Enrichment analysis
cluster analysis and association analysis on disease targets of cerebral ischemia were carried out through such databases as DAVID
String and The Human Phenotype Ontology. Finally
the regulatory network was constructed by Cytoscape3.4.0.
Result:
2
Compared with the sham group
the neurological impairment was obvious in the model group (
P
<
0.01)
and the neurological impairment was alleviated in the GH group compared with the model group (
P
<
0.05). RNA-Seq technology analysis showed that GH regulated genes involving such biological processes as cell apoptosis
inflammation
oxidative stress
toll-like signaling pathway and mitogen-activated protein kinase (MAPK) signaling pathway. Twenty disease targets and 64 MAPK signaling pathway genes were associated with differentially expressed genes after GH treatment
in which 23 genes were involved in apoptosis and inflammation.
Conclusion:
2
GH protected against cerebral ischemia in many ways
among which MAPK signaling pathway is an important way to exert its effect in inhibiting apoptosis and inflammation.
