| Summary: | The erythropoietin receptor (EPOR) is a transmembrane type I receptor with an essential role in the proliferation and differentiation of erythroid progenitors. Besides its function during erythropoiesis, EPOR is expressed and has protective effect in various non-hematopoietic tissues, including tumors. Currently, the advantageous aspect of EPOR related to different cellular events is still under scientific investigation. Besides its well-known effect on cell proliferation, apoptosis and differentiation, our integrative functional study revealed its possible associations with metabolic processes, transport of small molecules, signal transduction and tumorigenesis. Comparative transcriptome analysis (RNA-seq) identified 233 differentially expressed genes (DEGs) in EPOR overexpressed RAMA 37-28 cells compared to parental RAMA 37 cells, whereas 145 genes were downregulated and 88 upregulated. Of these, for example, <i>GPC4</i>, <i>RAP2C</i>, <i>STK26</i>, <i>ZFP955A</i>, <i>KIT</i>, <i>GAS6</i>, <i>PTPRF</i> and <i>CXCR4</i> were downregulated and <i>CDH13</i>, <i>NR0B1</i>, <i>OCM2</i>, <i>GPM6B</i>, <i>TM7SF3</i>, <i>PARVB</i>, <i>VEGFD</i> and <i>STAT5A</i> were upregulated. Surprisingly, two ephrin receptors, <i>EPHA4</i> and <i>EPHB3</i>, and <i>EFNB1</i> ligand were found to be upregulated as well. Our study is the first demonstrating robust differentially expressed genes evoked by simple EPOR overexpression without the addition of erythropoietin ligand in a manner which remains to be elucidated. |
