Abstract: Objective We used the Illumina sequencing platform to investigate the effect of p53 apoptosis stimulating protein 2 (ASPP2) on the expression of genes related to lipid metabolism in alcoholic liver disease. Methods The expression of ASPP2 was down-regulated by human hepatocyte HL-7702 cells infected with lentivirus. The two groups of cells (ASPP2-low and control) were cultured in a definite concentration of alcohol for 24 h. Then we used the Illumina sequencing platform to screen the differentially expressed genes. Then, a functional enrichment analysis and network interaction analysis were performed to explore the biological processes involving these genes. Results Total 150 differentially expressed genes were screened out by high-throughput sequencing according to the criteria of P<0.05 and | log2 (foldchange) |>1, of which 58 were up-regulated and 92 were down-regulated. Among them, there were 8 up-regulated genes and 7 down-regulated genes related to lipid metabolism. Gene ontology (GO) enrichment analysis found four cell components related to lipid metabolism, including high-density lipoprotein particles, plasma lipoprotein particles, lipoprotein particles, and protein-lipid complexes. Conclusion We found 15 different genes related to lipid metabolism in this study. These genes may be involved in ASPP2 mediated lipid accumulation in alcoholic liver disease, which lays a foundation for further study on the regulation mechanism of ASPP2 in lipid metabolism of alcoholic liver disease.
