Escape from stress granule sequestration: another way to drug resistance?
Overexpression of P-glycoprotein, encoded by the MDR1 (multidrug resistance 1) gene, is often responsible for multidrug resistance and chemotherapy failure in cancer. We have demonstrated that, in leukaemic cells, P-glycoprotein expression is regulated at the translational level. More recently, we have shown that in cells overexpressing P-glycoprotein, MDR1 mRNA does not aggregate into translat...
متن کاملEvolution of drug resistance in Candida albicans.
The widespread deployment of antimicrobial agents in medicine and agriculture is nearly always followed by the evolution of resistance to these agents in the pathogen. With the limited availability of antifungal drugs and the increasing incidence of opportunistic fungal infections, the emergence of drug resistance in fungal pathogens poses a serious public health concern. Antifungal drug resist...
متن کاملPopulation genomics of drug resistance in Candida albicans.
We followed adaptation in experimental microbial populations to inhibitory concentrations of an antimicrobial drug. The evolution of drug resistance was accompanied in all cases by changes in gene expression that persisted in the absence of the drug; the new patterns of gene expression were constitutive. The changes in gene expression occurred in four replicate populations of the pathogenic fun...
متن کاملGlucose promotes stress resistance in the fungal pathogen Candida albicans.
Metabolic adaptation, and in particular the modulation of carbon assimilatory pathways during disease progression, is thought to contribute to the pathogenicity of Candida albicans. Therefore, we have examined the global impact of glucose upon the C. albicans transcriptome, testing the sensitivity of this pathogen to wide-ranging glucose levels (0.01, 0.1, and 1.0%). We show that, like Saccharo...
متن کاملAssessing resistance to the echinocandin antifungal drug caspofungin in Candida albicans by profiling mutations in FKS1.
Resistance of clinical isolates of Candida albicans to the echinocandin drug caspofungin is slowly emerging and is linked to mutations in short conserved regions in the FKS1 gene. The most prominent changes occurred at the serine 645 position in Fks1p with substitutions of proline, tyrosine, and phenylalanine. An allele-specific real-time PCR molecular-beacon assay was developed for rapid ident...
