Project description:The objective of this study was to identify changes in gene expression levels between wild-type and NKCC1-knockout small intestine. 6 wild-type and 6 NKCC1-knockout small intestine RNA samples were compared. Total RNA was collected from both male and female 8-week old wild-type and NKCC1-null mice on an inbred FVB\N background. All comparisons were done between wild-type and NHE4-null samples from age- and gender-matched mice.
