Recently, in the model of DSS (Dextran Sulfate Sodium Salt) ‐induced intestinal inflammatory injury, it has been found in the study that transgenic mice expressing hVDR in IEC (Intestinal Epithelial Cell) manifest highly anti‐injury properties in colitis, suggesting that activated VDR in intestinal epithelial cells may inhibit colitis by protecting the mucosal epithelial barrier.11 This evidence concerns the gene VDR and colitis.
