Giardia intestinalis is a worldwide parasite. Drugs used for the treatment of giardiasis are metronidazole, albendazole and nitazoxanide. The development of drug resistance is an obstacle to the effective treatment. Resistance mechanisms in some parasites involve the participation of ATP-binding cassette (ABC) transporter superfamily. To find if the ATP-binding cassette genes are overexpressed in trophozoites treated with albendazole or nitazoxanide. A search for ATP-binding cassette genes in Giardia sequence database (GiardiaDB) was done and six genes were selected. Trophozoites treated with albendazole or nitazoxanide and the expression of these six ABC genes was quantitated by real-time RT-PCR. The ABC-C1 gene was selected, and a fragment cloned. The ABC-C1 protein was expressed, and polyclonal antibodies were elicited in mice to detect the protein in treated trophozoites, finally a docking anal. was performed for ABC-C1 and tizoxanide interaction. Bioinformatics anal. showed that the ATP-binding cassette (ABC) topol. is present in the six proteins. The qRT-PCR revealed that the ABC-C1 gene was overexpressed in cells incubated with nitazoxanide or albendazole. Confocal anal. showed that ABC-C1 protein levels increased in trophozoites with both treatments but was higher with nitazoxanide. The mark was detected heavily in the periphery of the cells. Using a docking anal., it was found that the nitazoxanide metabolite, tizoxanide was docked close to the ATP-binding region as well as in the exit tunnel, located in the transmembrane region. These findings in Giardia intestinalis, support the possible role of ABC-C1 in drug efflux. To complete the study, the researchers used 2-((5-Nitrothiazol-2-yl)carbamoyl)phenyl acetate (cas: 55981-09-4) .
