Abstract

The present study investigates the effects of PTEN deletion in human neuro and mesenchymal stem cells related to the chromosome 10 gene expression profile. The RNA sequencing (RNA-seq) performed on four neural and four mesenchymal stem cells. DEG analysis outcome revealed 122 genes for neural stem cells (57 up-regulated and 65 down-regulated genes) and 258 genes for mesenchymal stem cells (98 up-regulated and 160 downregulated genes) that were deferentially expressed in the PTEN (-/-) group compared to the normal group. Gene ontology analysis indicated that in the NSCs upregulated DEGs were significantly enriched in transcriptional activator activity, phosphatidylinositol phosphate phosphatase activity, MAP kinase activity while the downregulated DEGs were mainly involved in glycolytic process through glucose-6-phosphate, canonical glycolysis, glucose catabolic process to pyruvate. Meanwhile, in MSCs, the upregulated DEGs were mainly enriched in positive regulation of cell migration, chromatin silencing complex, RNA polymerase core enzyme binding while the downregulated DEGs phosphofructokinase activity, focal adhesion, glycolytic process through glucose-6- phosphate. On the basis of the PPI network of the DEGs, the following top hub genes were detected: six hub genes (PTEN, MAPK8, VCL, PAX2, ITGB1 and RET) in neural stem cells and 9 hub genes (PTEN, CDK1, KIF11, VCL, HK1, KIF20B, SIRT1, ACTR1A and ITGB1) appeared in mesenchymal stem cells respectively in each of the top 10 gene lists. In conclusion, PTEN, VCL and ITGB are found to be the main hub genes in both neural and mesenchymal stem cells, which involve in cell cycle, tumor progression and metastasis.
