Transcriptome Analysis of Candida albicans Biofilms Grown in the Presence of Arachidonic Acid and Fluconazole

Candida albicans is a commensal yeast within the human microbiota with significant medical importance because of its pathogenic potential. The yeast produces biofilms, which are highly resistant to available antifungals. High level of antifungal resistance by C. albicans biofilms has resulted in the need for alternative treatment. Polyunsaturated fatty acids such as arachidonic acid has been reported to increase the susceptibility of C. albicans biofilms to azole. However, the underlining mechanism is unknown. To unravel the mechanism behind this phenomenon, identification of differentially regulated genes in C. albicans biofilms grown in the presence of arachidonic acid, fluconazole, and the combination of both compounds was conducted using RNAseq. Investigation in triplicate three treatment conditions and a control
