Alternative sulphur metabolism in the fungal pathogen Candida parapsilosis.

Candida parapsilosis is an opportunistic fungal pathogen commonly isolated from the environment and associated with nosocomial infection outbreaks worldwide. We describe here the construction of a large collection of gene disruptions, greatly increasing the molecular tools available for probing gene function in C. parapsilosis.

Candida parapsilosis: from Genes to the Bedside.

Patients with suppressed immunity are at the highest risk for hospital-acquired infections. Among these, invasive candidiasis is the most prevalent systemic fungal nosocomial infection. Over recent decades, the combined prevalence of non- species outranked infections in several geographical regions worldwide, highlighting the need to understand their pathobiology in order to develop effective treatment and to prevent future outbreaks.

Gene editing in clinical isolates of Candida parapsilosis using CRISPR/Cas9.

Candida parapsilosis is one of the most common causes of candidiasis, particularly in the very young and the very old. Studies of gene function are limited by the lack of a sexual cycle, the diploid genome, and a paucity of molecular tools. We describe here the development of a plasmid-based CRISPR-Cas9 system for gene editing in C.

Comparative phenotypic analysis of the major fungal pathogens Candida parapsilosis and Candida albicans.

Candida parapsilosis and Candida albicans are human fungal pathogens that belong to the CTG clade in the Saccharomycotina. In contrast to C. albicans, relatively little is known about the virulence properties of C.

The Candida pathogenic species complex.

Candida species are the most common causes of fungal infection. Approximately 90% of infections are caused by five species: Candida albicans, Candida glabrata, Candida tropicalis, Candida parapsilosis, and Candida krusei. Three (C.

A "complex" issue: deciphering the role of variant PRC1 in ESCs.

Several noncanonical type-1 Polycomb Repressive Complexes (PRC1) that act independently of PRC2 have been recently identified, but their functions in embryonic stem cells (ESCs) are unclear. Two recent reports by Morey et al. (2012a) and Wu et al.

Polycomb PHF19 binds H3K36me3 and recruits PRC2 and demethylase NO66 to embryonic stem cell genes during differentiation.

Polycomb group proteins are repressive chromatin modifiers with essential roles in metazoan development, cellular differentiation and cell fate maintenance. How Polycomb proteins access active chromatin to confer transcriptional silencing during lineage transitions remains unclear. Here we show that the Polycomb repressive complex 2 (PRC2) component PHF19 binds trimethylated histone H3 Lys36 (H3K36me3), a mark of active chromatin, via its Tudor domain.
