Transcript profiling reveals the role of PDB1, a subunit of the pyruvate dehydrogenase complex, in Candida albicans biofilm formation

Abstract

Candida albicans, the most prevalent fungal pathogen in the human microbiota can form biofilms on implanted medical devices. These biofilms are tolerant to conventional antifungal drugs and the host immune system as compared to the free-floating planktonic cells. Several in vitro models of biofilm formation have been used to determine the C. albicans biofilm-forming process, regulatory networks, and their properties. Here, we performed a genome-wide transcript profiling with C. albicans cells grown in YPD medium both in planktonic and biofilm condition. Transcript profiling of YPD-grown biofilms was further compared with published Spider medium-grown biofilm transcriptome data. This comparative analysis highlighted the differentially expressed genes and the pathways altered during biofilm formation. In addition, we demonstrated that overexpression of the PDB1 gene encoding a subunit of the pyruvate dehydrogenase resulted in defective biofilm formation. Altogether, this comparative analysis of transcript profiles from two different studies provides a robust reading on biofilm-altered genes and pathways during C. albicans biofilm development.
