Indoleamine 2,3-dioxygenase 1, Increased in Human Gastric Pre-Neoplasia, Promotes Inflammation and Metaplasia in Mice and is Associated with Type II Hypersensitivity/Autoimmunity

Chronic gastrointestinal inflammation increases the risk of cancer by mechanisms that are not well understood. Indoleamine-2,3-dioxygenase 1 (IDO1) is a heme-binding enzyme that regulates the immune response via catabolization and regulation of tryptop… Continue reading

Association Between Germline Mutations in BRF1, a subunit of the RNA Polymerase III Transcription Complex, and Hereditary Colorectal Cancer

Although there is a genetic predisposition to colorectal cancer (CRC), few of the genes that affect risk have been identified. We performed whole-exome sequence analysis of individuals in a high-risk family without mutations in genes previously associa… Continue reading

Intestinal Dysbiosis Featuring Abundance of Ruminococcus gnavus Associates With Allergic Diseases in Infants

Dysbiosis of the intestinal microbiota has been associated with development of allergies in infants. However, it is not clear what microbes might contribute to this process. We investigated what microbe(s) might be involved in analyses of infant twins … Continue reading

A Nigro-Vagal Pathway Controls Gastric Motility and is Affected in a Rat Model of Parkinsonism

In most patients with Parkinson’s disease, gastrointestinal (GI) dysfunctions, such as gastroparesis and constipation, are prodromal to the cardinal motor symptoms of the disease. Sporadic Parkinson’s disease has been proposed to develop following … Continue reading
