Project description:The angio-suppressive effect of 20(R)-ginsenoside Rg3 (Rg3-R) has been previously demonstrated, and microRNAs (miRNAs) are a vital group of small non-coding RNAs that function as post-transcriptional modulator of gene expression. Thus, using human umbilical vein endothelial cells (HUVEC) as model, we compared the microRNA (miRNA) expression profile of vascular endothelial growth factor (VEGF)-induced cells with the profile of the cell co-treated with VEGF and Rg3-R. Among the screened 553 human miRNAs, 6 up-regulated (miR-520h, miR-487b, miR-197, miR-524*, miR-342 and miR-219) and 3 down-regulated (miR-23a, miR-489 and miR-377) miRNAs were detected in Rg3-R treated vascular endothelial growth factor (VEGF)-induced HUVECs compared to VEGF alone. Real time RT-PCR was subsequently performed to verify the miRNA microarray result. Two condition experiment: VEGF-induced HUVEC and VEGF-induced HUVEC treated with Rg3-R. Three independent microarray experiments, with triplicate per microarray.

Project description:Background: We investigated the effect of PPIA overexpression on downstream gene expression at the cellular level. Methods: The PPIA gene was overexpressed in human umbilical vein endothelial cells. Then, transcriptome sequencing was performed. The differentially expressed genes and genes with alternative splicing were screened. GO and KEGG analyses were performed. Nine differentially expressed genes and 7 genes with alternative splicing were validated by real-time quantitative PCR. Results: After PPIA overexpression, 328 genes were differentially expressed, including 157 up-regulated genes and 171 down-regulated genes. GO enrichment analysis of up-regulated genes found that the enriched GO terms included extracellular region, protein binding and metal ion binding, etc. For down-regulated genes, the enriched GO terms included neuron projection, protein binding, endoplasmic reticulum unfolded protein response, etc. KEGG showed that the up-regulated genes were mainly enriched in gastric acid secretion, AMPK signaling pathway, etc; and, the down-regulated genes were enriched in transcriptional misregulation in cancer, TNF signaling pathway, etc. Real-time quantitative PCR analysis of ATF4 (activating transcription factor 4), PPP1R15A (protein phosphatase 1, regulatory (inhibitor) subunit 15A protein phosphate 1, regulatory (inhibitor) subunit 15A), GADD45B (growth arrest and DNA damage inducible protein 45B), SGK1 (serum/glucocorticoid regulated kinase 1), DDIT3 (Recombinant DNA Damage Inducible Transcript 3), PMAIP1 (Phorbol-12-myristate-13-acetate-induced Protein 1), SULF1 (Sulfatase 1), GDF6 (Growth Differentiation Factor 6), and XBP1 (X-Box Binding Protein 1) obtained consistent results with the sequencing results. On the other hand, multiple genes with alternative splicing were identified and analyzed with KEGG and GO. Real-time quantitative PCR validation showed that the probability of alternative splicing in LHPP, APH1A, BRD1, and ORAI3 was increased. However, the changes of NFX1, SERGEF, and PCBP4 were inconsistent with the sequencing results. Conclusion: The overexpression of PPIA in human umbilical vein endothelial cells causes changes in the expression of downstream genes, and induces alternative splicing in multiple genes. PPIA may be involved in the development of atherosclerosis by regulating the expression of downstream genes and causing endothelial cell dysfunction.
