PRDM1 activated TOX gene transcription. (A) Transcription factor networks that drive the expression of TOX in total CD8+ T cells predicted by SCENIC. (B) Heatmap of regulators predicted by SCENIC that drives the expression of TOX in CD8+ T cells clusters. The PRDM1 regulon is indicated in red. (C) A conserved PRDM1‐binding motif at the TOX promoter was predicted by JASPAR. (D) Dual‐luciferase reporter assays of Jurkat cells transfected with PRDM1 overexpression plasmid and reporter plasmid containing TOX promoter (ANOVA, P < 0.0001, n = 3). Jurkat cells transfected with a blank pGL3 plasmid served as a negative control. Data are presented as means ± SD.
