Ascending colon-derived mucin-type O-glycans form key mucus layers encapsulating microbiota in the colon (RNA-seq)

Project description:The colon contains a dense metabolically potent microbiota. The colonic O-glycan-rich mucus has been recognized as a key barrier to prevent microbial intrusion, but how this system forms and functions remains unclear. Here, we discovered that the colon mucus is mainly forged by microbiota-dependent secretion of O-glycosylated Muc2 by goblet cells in the ascending colon, where it seamlessly encapsulates the fecal materials including the microbiota. Deletion of O-glycans in the ascending colon impaired the segregating function of the mucous coating, leading to altered structure and metabolic output of the microbiota, and transcriptional homeostasis of the entire host mucosa. These findings represent a paradigm change of the prevailing model of the colon mucus system and provides new insights into host and microbiota symbiosis.

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 Candida albicans grown in the presence or absence of mucin glycans

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

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.
