Discovery of an interplay between the gut microbiota and esophageal squamous cell carcinoma in mice.

ABSTRACT: Esophageal squamous cell carcinoma (ESCC) is the main type of esophageal cancer (EC) worldwide, causing half a million deaths each year. Recent evidence has demonstrated the role of the gut microbiota in health and disease. However, our current understanding of the gut microbiome in EC remains scarce. Here, we characterized the gut and esophageal microbiome in a metastatic mouse model of ESCC and examined the functional roles of the gut microbiota in EC development in fecal microbiota transplantation (FMT) experiments. Nude mice intraperitoneally xenografted with human EC-109 cells showed significant alterations in the overall structure, but not alpha diversity, of the gut and esophageal microbiome as compared to naïve control mice. Xenograft of EC cells depleted the order Pasteurellale
