摘 要:OBJECTIVE To investigate the transcriptomic details on the biosynthetic pathways in different parts of the Panax notoginseng and the pharmacological activity of the saponins extracted from the flower(FS)on vascular insufficiency *** RNA sequencing of three different Panax notoginseng tissues was performed using next generation DNA sequencing and differential gene expression was validated by real-time *** order to determine pro-angiogenic and therapeutic effects of FS on myocardial infraction(MI),FS was examined on the endothelial cell migration assay,vascular insufficiency model in zebrafish and MI model in *** After assembling the high quality sequencing reads into 107 340 unigenes,biochemical pathways were predicted and 9 908 unigenes were assigned to 135 KEGG *** them,270 unigenes were identified to be involved in triterpene saponin biosynthesis as well as 350 and 342unigenes were predicted to encode cytochrome P450 sand glycosyltransferases,*** unigene was annotated as CYP716A53v2,probably participates in the formation of protopanaxatriol from protopanaxadiol and the differential expression of this gene was confirmed by real-time *** addition,the pharmacological evaluation demonstrate that FS significantly promoted vascular endothelial growth factor(VEGF)induced the migration of human umbilical vein endothelial cells(HUVECs)and partially restored defective intersegmental vessels in a chemically induced vascular insufficiency model of zebrafish ***,the two week posttreatment of the rat MI model with FS(25-50mg·kg-1·d-1)induced approximately 3-fold upregulation of VEGF mRNA expression,with a concomitant increase in blood vessel density in the peri-infarct area of the heart by 50.7%,compared to 41.4%in the MI ***,TUNEL analysis indicates a reduction in the mean apoptotic nuclei per field in peri-infarct myocardium upon FS *** We have established a global transcriptome da
