Conclusions: These findings suggest that Mtgr1 has an important role in crypt survival and regeneration after colonic epithelial ulceration.
The regional variation in mucin characteristics and in crypt parameters could be explained by differences in functional status and/or in the local environment.
Furthermore, lactase mRNA was detected in fractionized villus and crypt layers of jejunum and ileum, but levels were higher in the jejunum in villus than in crypt fractions.
Weaning was also associated with a decrease in crypt density, an increase in mytotic index and a decrease in the number of goblet cells.
But that might be enough for folks like Alex Bellavia, the guy who helped kick things off with his discovery in Crypt of the Necrodancer earlier this year.
We predicted that levels of phospho-Tyr-15 would be elevated in crypt epithelial cells lacking the CDC25s.
Rad21+/− mice exhibited a dose-dependent decrease in crypt survival that is greater than WT (Fig. 4B).
However, as in the AOM/DSS model, we observed a decrease in crypt damage in TLR2 deficient colons as compared to WT colons.
This abnormal and uncontrolled growth pattern leads to a complete disruption of normal tissue architecture and a large increase in crypt length.
It is therefore plausible that mitotic catastrophe in crypt cells is consequential to their DSB-induced proliferative response during crypt regeneration in Rad21+/− animals.
Colonic crypts showed a progressive increase in colonocyte proliferation, an increase in crypt fission, and a strong inhibition of both differentiation and anoikis/apoptosis.
