The multidrug resistance gene Abcb1b is upregulated in mutant mice (J:39502). Liposome-mediated transfection of a vector containing the human CFTR gene into the lungs of these mutant mice corrected the conductance defect in airway epithelium (J:14625).

While heterozygous Cftrtm1Unc mice secrete half the wild-type amount of intestinal fluid in response to cholera toxin, no evidence for this has been found in ileal or colonic epithelium of heterozygous Cftrtm1Cam mice (J:23238). The Cftrtm1Unc response has been proposed as an advantage for heterozygotes, providing protection from the dehydration resulting from cholera. A similar effect of the human CFTR mutation might account for the high frequency of mutant genes in the human population (J:20778).
