摘要
Objectives:The focus of this study was to investigate a possible mechanism of CD8~+ regulatory T cell(Treg) production in ovarian cancer(OC) microenvironment.Methods:Agilent microarray was used to detect changes in gene expression between CD8~+ T cells cultured with and without the SKOV3 ovarian adenocarcinoma cell line.RT-q PCR was performed to determine expression of glycolysis gene expression in CD8~+ T cells from transwell culturing system and OC patients.We also detected the protein level of glycolysis related genes using western blot.Results:Comparing gene expression profiles revealed significant differences in the expression levels of 1,420 genes,of which 246 were upregulated and 1,174 were downregulated.Gene ontology and Kyoto encyclopedia of genes and genomes analysis indicated that biological processes altered in CD8~+ Treg are particularly associated with energy metabolism.CD8~+ Treg cells induced by co-culture with SKOV3 had decreased glycolysis gene expression compared with CD8~+T cells cultured alone.Glycolysis gene expression was also decreased in the CD8~+ T cells of ovarian cancer patients.Conclusions:These findings provide a comprehensive bioinformatics analysis of DEGs in CD8~+ T cells cultured with and without the SKOV3,and suggest that metabolic processes may be a possible mechanism for CD8~+ Treg induction.
