Gene expression profiles of chimeric antigen receptor T cells with knockout of epigenetic genes

ABSTRACT: Persistence of infused antitumor T cells is one of the essential factors for durable therapeutic response. T cells undergo genome-wide alterations in epigenetic architecture upon repeated antigen encounter, which is inevitably accompanied by progressive T cell differentiation and loss of longevity. In this study, we explored key epigenetic factors associated with terminal T cell differentiation using CRISPR/Cas9-mediated knockout of epigenetic genes in chimeric antigen receptor (CAR)-engineered human T cells and identified multiple key epigenetic genes. We analyzed gene expression profiles of CAR-T cells that were knocked out with the specific epigenetic genes by RNA-sequencing.
