Alterations in the intestine of Patagonian silverside (Odontesthes hatcheri) exposed to microcystin-LR: Changes in the glycosylation pattern of the intestinal wall and inhibition of multidrug resistance proteins efflux activity.

⿢O. hatcheri received MCLR through the diet for lectin-histochemistry studies.⿢MCLR changed the intestinal epithelium glycoconjugates composition and distribution.⿢MCLR transport was studied in ex vivo O. hatcheri⿿s intestine preparations.⿢MCLR inhibited apical and basolateral transport of Abcc substrates (DNP-SG, calcein).⿢MCLR would be excreted and/or absorbed to the blood by Abcc proteins.
