Glycerophospholipids and sphingolipids are distributed asymmetrically between the two leaflets of the lipid bilayer. Recent studies revealed that certain P-type ATPases and ATP-binding cassette (ABC) transporters are involved in the inward movement (flip) and outward movement (flop) of glycerophospholipids, respectively. In this study of phytosphingosine (PHS)-resistant yeast mutants, we isolat...
ژن PDR5 (pleotropic drug resistance 5)کد کننده پروتئین ناقل ABC ) (ATP Binding Cassette است که با استفاده از هیدرولیز ATP در سم زدایی از سلولها نقش دارد. جهت ایجاد نشانگر مبتنی بر PCR برای ژن کاندیدای مقاومت به بلایت فوزاریومی سنبله (PDR5) در گندم ردیفهای مشابه با این ژن با استفاده از نرمافزار DNASTAR همردیف شدند. آغازگرها با استفاده از نواحی حفظ شده و غیر حفظ شده این ژن طراحی شدند. تجزیه م...
fusarium head blight (fhb) caused by fusarium graminearum is a serious disease of wheat (triticum aestivum l.), through which grain quality losses are induced by fungal trichotecene mycotoxins such as deoxynivalenol (don). a class of plasma membrane localized abc transporter proteins related to the yeast pdr5 (pleiotropic drug resistance5) efflux pump seems to be responsible for partial resista...
Multidrug resistance protein Pdr5p is a yeast ATP-binding cassette (ABC) transporter in the plasma membrane. It confers multidrug resistance by active efflux of intracellular drugs. However, the highly polymorphic Pdr5p from clinical strain YJM789 loses its ability to expel azole and cyclohexmide. To investigate the role of amino acid changes in this functional change, PDR5 chimeras were constr...

The antineoplastic alkaloid camptothecin interferes with the catalytic cycle of DNA topoisomerase I rendering it a cellular poison. Camptothecin stabilizes a covalent enzyme-DNA intermediate that is converted into lethal double strand DNA lesions during S phase of the cell cycle. Yeast SCT1 mutants were isolated in a screen for mutations in genes other than TOP1 that result in camptothecin resi...
The commonly used drug diclofenac is an important environmental anthropogenic pollutant. Currently, detection of diclofenac is mainly based on chemical and physical methods. Here we describe a yeast biosensor that drives the diclofenac-dependent expression of a recombinant fluorescent protein from the authentic promoter of the PDR5 gene. This key component of the pleiotropic drug response encod...
The inhibition of ABC (ATP binding cassette) transporters is considered a powerful tool to reverse multidrug resistance. Zosuquidar featuring a difluorocyclopropyl-annulated dibenzosuberyl moiety has been found to be an inhibitor of the P-glycoprotein, one of the best-studied multidrug efflux pumps. Twelve 5-oxyisoquinoline derivatives, which are analogues of zosuquidar wherein the dibenzosuber...
Doxorubicin is one of the most potent anticancer drugs used in the treatment of various cancer types. The efficacy of doxorubicin is influenced by the drug resistance mechanisms and its cytotoxicity. In this study, we performed a high-copy screening analysis to find genes that play a role in doxorubicin resistance and found several genes (CUE5, AKL1, CAN1, YHR177W and PDR5) that provide resista...
Hyperexpression of the Saccharomyces cerevisiae multidrug ATP-binding cassette (ABC) transporter Pdr5p was driven by the pdr1-3 mutation in the Pdr1p transcriptional regulator in a strain (AD/PDR5(+)) with deletions of five other ABC-type multidrug efflux pumps. The strain had high-level fluconazole (FLC) resistance (MIC, 600 microg ml(-1)), and plasma membrane fractions showed oligomycin-sensi...
