Primary Chemoprevention of Familial Adenomatous Polyposis With Berberine Hydrochloride
Palabras clave

Descripción
Familial adenomatous polyposis is an autosomal dominant syndrome caused by a germ-line mutation of the adenomatous polyposis coli (APC) gene located at chromosome 5q21. The disorder is characterized by the development of hundreds of colorectal adenomas during adolescence. Colorectal cancer will develop in nearly all affected persons by the sixth decade of life if prophylactic colectomy is not performed. Because the adenoma-to-carcinoma sequence in familial adenomatous polyposis resembles sporadic colon carcinogenesis, studies of familial adenomatous polyposis may contribute to the prevention of sporadic adenomas and colon cancer.
BBR, an isoquinoline alkaloid, is a natural compound in numerous Chinese herb plants such as Berberisaristata, Coptischinensis, Coptis rhizome, etc. In recent years, Berberine hydrochloride has been reported to inhibit cancer cell proliferation and to be cytotoxic towards cancer cells. The aim of this study is to investigate the regression effect of Berberine hydrochloride on the colorectal adenomas in patients with familial adenomatous polyposis.
