Description
This experiment was performed to assess the effect of loss of Hnf4a in the intestinal epithelium on the regeneration process after irradiation. Intestinal epithelium specific knockout was obtained by oral adminstration of tamoxifen to VillinCreERT2+-Hnf4afl/fl mice and VillinCreERT2--Hnf4afl/fl mice (which served as controls). 3 weeks after the tamoxifen administration, mice received 14 Gy whole-body gamma-irradiation. RNA was extracted from small intestinal tissue 96 hours after irradiation.
