SGK1 and microvillus inclusion disease: Since our cMYO5BKO mouse model replicates human MVID and a role for SGK1 in MVID diarrhea has not been considered before, we used immunohistochemistry to examine the phosphorylation status of SGK1 in the small intestine of R26CreER;MYO5Bf/f (cMYO5BKO), compared to heterozygous and wild type mice.
