Restoring CTCF expression in CD4+ T cells from aGVHD cases improves Treg/Th17 cell imbalance by increasing p53 expression. (A,B) ChIP-qPCR analysis of the enrichment of p300 binding (A) and H3K9/K14 (B) acetylation levels in the p53 promoter region in CD4+ T cells from three separate aGVHD cases after CTCF overexpression. Values are relative to those obtained with input DNA prepared from untreated chromatin. Data are mean ± SD from three independent experiments. (C,D) Real-time PCR analysis of p53, Foxp3, IL-10 (C), RORγt, and IL-17A (D) expression levels in CD4+ T cells from three separate aGVHD cases after CTCF overexpression. Data are mean ± SD from three independent experiments. P < 0.05, ∗∗P < 0.01.
