RNA-seq Analysis of Wild-Type and G898D UPC2A Transcriptomes [G898D UPC2A transcriptome]

Purpose: Determine the number of genes that respond to the presence of a gain-of-function mutant form of the UPC2A transcription factor in Candida glabrata. Methods: Prepare total RNA from wild-type and gain-of-function G898D UPC2A cells. Use standard RNA-seq to evaluate and compare the transcriptomic changes caused by this allele of UPC2A. Results: Although a clear increase was seen in fluconazole resistance conferred by the G898D UPC2A allele, elevated transcription was only observed for 11 genes with 9 of these involved in ergosterol biosynthesis. Conclusions: The presence of the G898D UPC2A allele led to elevated constitutive transcription for genes involved in ergosterol biosynthesis. Overall design: Candida glabrata mRNA profiles of wild-type (WT) and G898D UPC2A strains grown to mid-log phase.
