SLC26A9 and intestinal obstruction: Our data clearly show that Slc26a9 expression is negligible in the part of the murine and human intestine that is obstructed in the murine CFTR-deficiency-related intestinal obstruction (mid jejunum to ileum) and human CF meconium ileus (ileum and proximal colon); and Slc26a9 expression is not increased in CFTR deficient compared to WT distal small intestine and colon (data not shown).
