The unfolded protein response (UPR) regulates the expression of genes involved in the protein secretory pathway and in endoplasmic reticulum (ER) stress in yeasts and filamentous fungi. We have characterized the global transcriptional response of Candida albicans to ER stresses (dithiothreitol and tunicamycin) and established the impact of the transcription factor Hac1 upon this response. Expression of C. albicans Hac1, which is the functional homologue of Saccharomyces cerevisiae Hac1p, is predicted to be translationally regulated via an atypical mRNA splicing event during ER stress. C. albicans genes involved in secretion, vesicle trafficking, stress responses and cell wall biogenesis are up-regulated in response to ER stress, and translation and ribosome biogenesis genes are down-regulated. Hac1 is not essential for C. albicans viability, but plays a major role in this stress-related transcriptional response and is required for resistance to ER stress. In addition, we show that Hac1 plays an important role in regulating the morphology of C. albicans and in the expression of genes encoding cell surface proteins during ER stress, factors that are important in virulence of this fungal pathogen.
