| the ccaat-binding complex controls respiratory gene expression and iron homeostasis in candida glabrata. | the ccaat-binding complex (cbc) is a heterotrimeric transcription factor which is widely conserved in eukaryotes. in the model yeast s. cerevisiae, cbc positively controls the expression of respiratory pathway genes. this role involves interactions with the regulatory subunit hap4. in many pathogenic fungi, cbc interacts with the hapx regulatory subunit to control iron homeostasis. hapx is a bzip protein which only shares with hap4 the hap4like domain (hap4l) required for its interaction with cb ... | 2017 | 28615656 |
| glabridin triggers over-expression of mca1 and nuc1 genes in candida glabrata: is it an apoptosis inducer? | the growing trends of emergence of antifungal-resistant candida strains has recently been inspired the researchers to design new antifungal agents with novel mechanisms of action. glabridin is an originally natural substrate with multiple biological activities which propose it as a novel anticancer, antimicrobial and antifungal agent. in the present study, the antifungal effect of glabridin against candida glabrata isolates and its possible mechanism of action were investigated. the minimum inhi ... | 2017 | 28595940 |

| generational distribution of a candida glabrata population: resilient old cells prevail, while younger cells dominate in the vulnerable host. | similar to other yeasts, the human pathogen candida glabrata ages when it undergoes asymmetric, finite cell divisions, which determines its replicative lifespan. we sought to investigate if and how aging changes resilience of c. glabrata populations in the host environment. our data demonstrate that old c. glabrata are more resistant to hydrogen peroxide and neutrophil killing, whereas young cells adhere better to epithelial cell layers. consequently, virulence of old compared to younger c. glab ... | 2017 | 28489916 |
