ACTB and inflammatory bowel disease: The expression levels of the KCa3.1 transcripts that were relative to β-actin (ACTB) (in arbitrary units) were 0.028 ± 0.001 and 0.053 ± 0.003 in normal and IBD model mice, respectively (n = 4 for each, p < 0.01) (Figure 1A), and those of the KCa3.1 proteins were approximately 1.8-fold higher in IBD model mice compared with the normal ones (n = 4 for each, p < 0.01) (Figure 1C).
