Abstract:
Objective:Transcriptomics combined with proteomics was used to analyze the potential signaling pathways of epidermal growth factor-like domain 9 (EGFL9) affecting the proliferation, invasion and migration of hepatocellular carcinoma.Methods:RNA interference technique was used to build hepatocellular carcinoma cell line with EGFL9 Huh-7 gene knockdown, the control group (NC group) and experimental group (KD group), each group of three samples, were performed the transcriptome and proteomics analysis, screening differences genes and proteins, to express the correlation analysis, cluster analysis, and subsequently gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) were used for gene function and pathway annotation enrichment analysis, respectively.Results:Based on omics analysis, there were 8 335 different genes in KD group compared with NC group, among which 4 207 were up-regulated and 4 128 were down-regulated. There were 298 different proteins, of which 188 were up-regulated and 110 down-regulated. Based on the combined analysis of the two omics, 213 differentially expressed genes were found. Among them, the top three common differentially expressed genes at the level of transcription and translation were transferrin receptor 2 (TFR2), annexin A1 (ANXA1) and solute carrier family 38 member 2(SLC38A2). The common differentially expressed genes were significantly enriched in cell cycle signaling pathway, amino acid biosynthesis pathway, p53 signaling pathway and glycolysis/gluconeogenesis signaling pathway.Conclusion:EGFL9 may participate in the regulation of cell function of hepatocellular carcinoma cells by regulating the expression of TFR2, ANXA1, LC38A2 and other genes, and may play a role through the regulation of cell cycle and other molecular signaling pathways.
