Physiological changes induced by heme in colon of WT and PPARα KO mice.

#<p>Calculated as percentage Ki67 positive cells per crypt. Data are represented as mean ± SEM. Groups indicated with ‘a’ are significantly (<i>P</i><0.05) different from ‘b’ by ANOVA with Bonferroni post-hoc testing. N = 6 per group, except for mucosa measurements where proliferation of one KO heme animal could not be determined due to poor tissue quality.
