ABSTRACT
BACKGROUND:
A previous study by our group found that protein phosphatase 2Cm(PP2Cm)null mice developed significantly fewer symptoms of renal failure relative to wild-type mice,and thus it was speculated that PP2Cm may play an important protective role in the development of renal fibrosis,however,the molecular mechanisms remain undefined.OBJECTIVE:
To investigate the effect of the PP2Cm gene on the transcriptome of human renal tubular epithelial cells.METHODS:
Cultured human renal tubular epithelial cells were transfected with the PP2Cm gene into human renal tubular epithelial cells using plasmids.The expression of PP2Cm in the cells was detected by fluorescence quantitative PCR assay and western blot assay,and subsequently,cell RNA was separately extracted for transcriptome sequencing to look for differentially expressed genes between transfected and control groups.The resulting differential genes were further subjected to GO analysis and KEGG analysis using bioinformatics methods. RESULTS ANDCONCLUSION:
There were 796 differentially expressed genes,553 of which were downregulated genes and 243 upregulated genes,in human renal tubular epithelial cells transfected with the PP2Cm gene compared with untransfected blank cells by sequencing analysis.GO analysis results showed that the upregulated genes were significantly enriched in cellular biosynthetic processes,protein translation,intrinsic apoptotic signaling pathways,and so on.The downregulated expressed genes were significantly enriched in endothelial cell proliferation,cell adhesion and other signaling pathways.KEGG analysis results showed that the significantly up-regulated genes were enriched in metabolism-related signaling pathways such as amino acid metabolism and biosynthesis.The downregulated expressed genes were significantly enriched in signaling pathways such as pantothenate and coenzyme A biosynthesis.Our results show that PP2Cm overexpression can affect a number of signaling pathways related to a range of biological processes in renal tubular epithelial cells,which may be important in metabolism-related signaling pathways such as amino acid metabolism and biosynthesis.
