Reduced VDR expression in a colitis mouse model. (A) VDR staining in DSS mice model. Images were representative of experiments in triplicate; Normal, n = 6; DSS, n = 8. (B) Comparison of RT-PCR expression profiles of Vdr gene from paired DSS-treated and control fecal samples. VDR expression was down-regulated in DSS-induced IBD mice model. Data are expressed as mean ± SD. n = 6, Student's t-test, ∗P < 0.05. (C) Comparison of RT-PCR expression profiles of Vdr gene from paired DSS-treated and control intestinal samples. VDR expression was reduced in colon from DSS-treated mice. Data are expressed as mean ± SD. n = 6, Student's t-test, ∗P < 0.05.
