HDAC2 and inflammatory bowel disease: The expression levels of HDAC2 and HDAC3 transcripts in arbitrary units were 0.034 ± 0.003 and 0.093 ± 0.006 (for HDAC2) and 0.017 ± 0.002 and 0.042 ± 0.007 (for HDAC3) in the CD4+CD25− T cells of normal and IBD model mice, respectively (n = 4 for each, p < 0.01) (Figure 3B,C).
