Figure 1From: Vitamin D and the vitamin D receptor are critical for control of the innate immune response to colonic injuryIncreased mortality of VDR KO mice following DSS administration. A) Survival curves in VDR KO and WT mice induced to develop DSS colitis. VDR KO mice died following 2.5% or 3.5% DSS treatment while all of the WT mice survived regardless of DSS concentrations. B) BW recovery over time post-DSS treatment. Mice were treated with 2.5% DSS for 5 days. VDR KO mice failed to recover BW following cessation of DSS. C) Colon length at day 0 (control-CTRL), day 5 and day 10 of DSS-exposure in WT and VDR KO mice. D) VDR KO mice were administered 0.5%–2% and WT mice received 1–2% DSS (n = 5/group). BW changes were monitored, and the values are expressed as the percentage of original BW. *Values from VDR KO mice were significantly different than corresponding values from WT mice. ** WT day 10 colon lengths were significantly longer than WT day 5 colon lengths.Back to article page
