Project description:Deubiquitinating enzymes (DUBs) are divided into seven subgroups based on sequence and structure and perform the roles of mediating the deubiquitination of substrate proteins, regulating protein function, and participating in various cellular life activities. Among them, the ubiquitin-specific protease family (USP) is the DUB subtype with the most members and structural diversity discovered so far. USP48 is a member of the USP family of ubiquitin-specific proteases and has been found to promote glioblastoma by deubiquitinating the Gli1 transcription factor and to promote the progression of non-small-cell lung cancer through inhibition of the Wnt/β-catenin signaling pathway. We used microarrays to detail changes in gene expression regulated by USP48 overexpression in HCC cells.
Project description:Purpose: The purpose of this study was to find the differentially expressed genes in RBP4 and control treated cells by transcriptome analysis (RNA-seq) for subsequent mechanism study. Methods: Illumina Novaseq™ 6000 was used to sequencing RBP4 and control-treated human umbilical vein endothelial cells.Genes differential expression analysis was performed by DESeq2 software between two different groups (and by edgeR between two samples). The genes with the parameter of false discovery rate (FDR) below 0.05 and absolute fold change ≥ 2 were considered differentially expressed genes. Differentially expressed genes were then subjected to enrichment analysis of GO functions and KEGG pathways.GO enrichment analysis provides all GO terms that significantly enriched in DEGs comparing to the genome background. Firstly all DEGs were mapped to GO terms in the Gene Ontology database (http://www.geneontology.org/), gene numbers were calculated for every term, significantly enriched GO terms in DEGs comparing to the genome background were defined by hypergeometric test. Results:The RNA-seq results showed that compared to the untreated HUVECs, RBP4 treatment resulted in significant changes in the gene expression, including 180 up-regulated and 53 down-regulated genes among a total number of 233 DEGs. GO enrichment were analyzed for relationships among all DEGs. Conclusions: Our study analyzed the mechanism of RBP4 on human umbilical vein endothelial cells and its possible pathway in detail by RNA-seq technique, and provided a basis for elucidating the damage of RBP4 on endothelial cells through large-scale gene screening.
