Gastric intestinal metaplasia

How are we addressing gastric intestinal metaplasia ?

Bile acid promotes intestinal metaplasia and gastric carcinogenesis.

BACKGROUND Bile acid and Helicobacter pylori (H. pylori) are important toxic factors for gastric mucosal injury. We examined the role of bile acid in promoting histologic gastritis and gastric carcinoma in Japanese patients. METHODS A total of 767 patients (452 men, mean age 51.1 years) were studied. Gastric juice was collected by gastro-endoscopic examination, and the bile acid concentration...

Role of intestinal metaplasia in the histogenesis of gastric carcinoma.

Recent evidence suggests that intestinal metaplasia (IM) cannot be regarded as a single entity. A simple classification of IM and its variants based on histological and mucin histochemical criteria was devised, and the incidence of IM subtypes in cancerous and benign gastrectomy specimens was recorded. A particular subtype was associated with 'intestinal' cancers but not with tumours considered...

Pericryptal fibroblast sheath in intestinal metaplasia and gastric carcinoma.

BACKGROUND AND AIMS In the progression of chronic gastritis, gastric mucosal cells deviate from the normal pathway of gastric differentiation to an intestinal phenotype which is closely related to gastric carcinoma. However, to date, it has not been elucidated whether the intestinal metaplasia is merely a change in the epithelium or whether the underlying mesenchyme also changes from gastric ty...

Potential role of aquaporin 3 in gastric intestinal metaplasia

Gastric intestinal metaplasia (GIM) is a pre-cancerous condition and a pivotal step in the formation of gastric cancer (GC). Aquaporin 3 (AQP3) has been found to be expressed in goblet cells rather than mucus-secreting glands. To investigate the characteristics of GIM in non-cancerous tissues adjacent to GC, as well as the expression and role of AQP3 in GIM tissues, 16 patients diagnosed with g...
