Transcriptomic profiles of Candida albicans grown in the presence or absence of mucins

Project description:We use high-throughput sequencing to profile the response of the opportunistic fungal pathogen Candida albicans to mucins from the mucosal niche. We find that C. albicans undergoes a genome-wide phenotypic shift in response to mucins suppressing virulence-associated pathways.

Transcriptional profiling of C. albicans in the presence of mucin versus absence of mucin

Project description:Candida albicans is the most prevalent fungal pathogen of humans, causing a variety of diseases ranging from superficial mucosal infections to deep-seated systemic infections. Mucus, the gel that coats all wet epithelial surfaces, accommodates Candida albicans as part of the regular microbiome where C. albicans resides asymptomatically in healthy humans. Through a series of in vitro experiments combined with genome-wide transcriptional profiling, we show that mucin biopolymers, the main gel-forming constituents of mucus, induce a new oval-shaped morphology in C. albicans in which a range of genes related to adhesion, filamentation, and biofilm formation are down-regulated. We also show that corresponding phenotypes are suppressed, rendering Candida incapable of forming biofilms on a range of different synthetic surfaces and human epithelial cells. Our data suggests that mucins can manipulate Candida physiology and we hypothesize that they are key regulators for retaining Candida in the host-compatible, commensal state. 3 biological replicates grown in log phase in the presence and absence of mucin for 8 hours. Experiments were performed using RPMI 1640 (Gibco 31800-089) buffered with 165mM MOPS and supplemented with 0.2% NaHCO3 and 2% glucose with and without 0.5% mucin.

Transcriptomic profiles of Streptococcus mutans UA159 grown in the presence or absence of mucins or mucin glycans

Project description:We use high-throughput sequencing to profile the response of oral commensal pathogen Streptococcus mutans to mucins protein polymers (human MUC5B mucins) and soluble mucin glycans (human MUC5B glycans and porcine MUC5AC glycans). We find that mucins and their glycans alter the regulation of dozens of S. mutans genes, specifically downregulating competence-associated quorum sensing genes. The transcriptional responses induced by MUC5B mucins, MUC5B glycans, and MUC5AC glycans are highly correlated.

Transcriptomic profiles of Pseudomonas aeruginosa PA14 grown in the presence or absence of mucins or mucin-glycans

Project description:We use high-throughput sequencing to profile the response of the opportunistic mucosal pathogen Pseudomonas aeruginosa to mucins and mucin-glycans from the mucosal niche. We find that P. aeruginosa undergoes a genome-wide phenotypic shift in response to mucins and their attached glycans. Specifically, nearly all virulence pathways are downregulated in response to these host-produced factors. This study provides a framework for understanding how the host environment regulates bacterial function.
