Fungal ATP-Binding Cassette (ABC) Transporters in Drug Resistance & Detoxification

Sipos, Gyorgy, Kuchler, Karl·2006·Current Drug Targets

Abstract

Pleiotropic drug resistance (PDR) is a well-described phenomenon occurring in fungi. PDR shares several similarities with processes in bacteria and higher eukaryotes. In mammalian cells, multidrug resistance (MDR) develops from an initial single drug resistance, eventually leading to a broad cross-resistance to many structurally and functionally unrelated compounds. Notably, a number of membrane-embedded energy-consuming ATP-binding cassette (ABC) transporters have been implicated in the development of PDR/MDR phenotypes. The yeast Saccharomyces cerevisiae genome harbors some 30 genes encoding ABC proteins, several of which mediate PDR. Therefore, yeast served as an important model organism to study the functions of evolutionary conserved ABC genes, including those mediating clinical antifungal resistance in fungal pathogens. Moreover, yeast cells lacking endogenous ABC pumps are hypersensitive to many antifungal drugs, making them suitable for functional studies and cloning of ABC transporters from fungal pathogens such as Candida albicans. This review discusses drug resistance phenomena mediated by ABC transporters in the model system S. cerevisiae and certain fungal pathogens.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
