title: [Pten gene expression in the endometrial mucosa].
abstract: The opinions about the causes of the endometrial carcinoma have changed since 1995, due to molecular biology progress. The findings concerning the recently discovered suppressor PTEN gene localized on the chromosome 10 -10q23.3, the product of which is a specific phosphatase are especially valuable. The loss of the gene function is directly linked with the genesis and progression of endometrial carcinoma, as well as cancers of other tissues and organs, including thyroid, breast, ovary, prostate or skin. Immunohistochemical studies with the use of the 6H2.1 antibody directed against the protein coded by the PTEN gene indicate that the protein cannot be found in more than half of the patients with endometrial carcinoma and its precursor--EIN. Mutations of the PTEN gene have also been detected in many young women with normal microscopic structure of the endometrial mucosa. Thus, a test for the absence of the PTEN gene product in the endometrial cells may be used for precise identification of early stages of carcinogenesis.
