Effect of ATP2 deletion on protein expression in Candida albicans

ABSTRACT: To investigate the effect of ATP2 knockdown on the protein expression of Candida albicans, we performed proteomic assays for atp2Δ/Δ and wild type strains. A total of 4000.0 proteins were identified in this study, of which 3652.0 proteins contained quantitative information. If a 1.5-fold differential expression change threshold and a statistical test t-test p-value < 0.05 were used as the significance threshold, then among the quantified proteins, we found that 112 proteins were up-regulated and 268 proteins were down-regulated in atp2Δ/Δ cells. Based on the above data, we performed systematic bioinformatics analysis (protein functional annotation) of all identified proteins, and performed functional classification, functional enrichment and functional enrichment-based clustering analysis of all differentially expressed proteins.

Macrophages provide the first-line defense against invasive fungal infections and, therefore, escape from macrophage becomes the basis for the establishment of <i>Candida albicans</i> invasive infection. Here, we found that deletion of <i>ATP2</i> (<i>atp2</i>Δ/Δ) in <i>C. albicans</i> resulted in a dramatic decrease from 69.2% (WT) to 1.2% in the escape rate <i>in vitro</i>. The effect of <i>ATP2</i> on macrophage clearance stands out among the genes currently known to affect clearance. In the  ...[more]
