Does dietary Genistein rescue Reduced Basal Chloride Secretion in Diabetic Jejunum via Sex-Dependent Mechanisms?
Our data suggests that the reduced basal jejunal Isc in ob/ob female mice is a consequence of reduced CFTR expression, decreased activities of the basolateral KCa channel and Na+/K+-ATPase, and in male mice reduced basal jejunal Isc is a consequence of reduced CFTR and NKCC1 expression, along with decreased activities of the basolateral KCa channel and Na+/K+-ATPase. Genistein-diet has beneficial effects on basal Isc mediated by sex-dependent mechanisms in diabetic mice: in females via increased KCa-sensitive Isc and in males via increased Na+/K+-ATPase activity and increased NKCC1 expression. Improved understanding of intestinal dysfunctions in the ob/ob jejunum, may allow for the development of novel drug targets to treat obesity and diabetes, and may also be of benefit in CF-related diabetes.
