Immunoblot analyses of Na+/H+ exchangers (NHE1, NHE2, NHE3), Na+ channel subunits (ENaC-α, ENaC-β, ENaC-γ), ATPase, and AT2 receptor in protein extracts of distal colon from CON, CRF, and + LOS rats. Membranes were reprobed for GAPDH as an internal loading control. Results were quantitated by densitometry from n = 4 to 6 tissues in each group and given in arbitrary units. Significant differences in CRF and + LOS from CON rats were established by a one-way ANOVA followed by Bonferroni's t-test and are indicated by an asterisk.
