Collaborating genomic, transcriptomic and microbiomic alterations lead to canine extreme intestinal polyposis

Intestinal Polyposis

Oral Pigmentation and Intestinal Polyposis

IN 1921 Peutz described a family with intestinal polyposis and spots of melanin pigmentation in and around the mouth. Prior to this, in 1896, Sir Jonathan Hutchinson described two girls with pigmented patches in the oral mucosa and around the mouth. Later, Parkes Weber (1919) reported that one of these twins died of what appeared to be an intussusception. Since 1921 over one hundred cases have ...

Familial intestinal polyposis.

Familial polyposis is of interest for its own sake as a sort of pathological curiosity and also in relation to the problem of cancer. The term " polyposis " is used to describe a widespread adenomatous proliferation of the intestinal mucous membrane, leading to the formation of multiple adenomata. It should not be applied to intestinal polyps of different histological structure, such as inflamm...

Genomic and Transcriptomic Alterations Associated with STAT3 Activation in Head and Neck Cancer

BACKGROUND Hyperactivation of STAT3 via constitutive phosphorylation of tyrosine 705 (Y705) is common in most human cancers, including head and neck squamous carcinoma (HNSCC). STAT3 is rarely mutated in cancer and the (epi)genetic alterations that lead to STAT3 activation are incompletely understood. Here we used an unbiased approach to identify genomic and epigenomic changes associated with p...

IL-33 activates tumor stroma to promote intestinal polyposis.

Tumor epithelial cells develop within a microenvironment consisting of extracellular matrix, growth factors, and cytokines produced by nonepithelial stromal cells. In response to paracrine signals from tumor epithelia, stromal cells modify the microenvironment to promote tumor growth and metastasis. Here, we identify interleukin 33 (IL-33) as a regulator of tumor stromal cell activation and med...
