Background: Endometrial carcinoma is the most common malignancy of the female genital tract. Different molecular alterations have been described in endometrioid endometrial carcinoma that, the most frequently altered gene is mutations of PTEN. Up to 50-83% of endometrioid carcinoma reveal altered PTEN characterized by loss of expression. In endometrial hyperplasia, which are precursors of endom...

background: in 1997 mmac1 or the pten gene, was identified as a tumor suppressor gene on the long arm of chromosome 10.pten involves in the balance between proliferation, and differentiation, apoptosis and regulation of angiogenesis, and eventually mutation in this gene causes a strong potential for tumorigenesis cells. this study is the first report of the correlation between pten gene mutatio...

Background and purpose: T-cell acute lymphoblastic leukemia (T-ALL) is a type of blood malignancy caused by changes in the precursors of T lymphocyte cells. The PTEN gene is one of the most common tumor suppressor genes that mutates in most human cancers, including T-ALL. Therefore, it is important to identify miRNAs that target the PTEN gene in T-ALL. For this purpose, in the present study, mi...

Introduction: The PTEN gene, also known as MMAC1 or TEP1, is a tumor suppressor gene. One of the important polymorphisms of this gene is the rs10490920 SNP. The purpose of this study was to determine the PTEN gene expression and its relation to changes in rs10490920 polymorphism in breast cancer. Methods: In this study, 40 breast cancer patients and 10 healthy controls were considered. The expr...

Background and purpose: Colorectal cancer ( CRC ) is highly prevalent and conventional therapies are associated with side effects, therefore, application of novel complementary treatment such as probiotics (especially Saccharomyces cerevisiae) is necessary. The aim of this study was to investigate the effect of heat-killed form of S.cerevisiae on growing rate and apoptosis (expression levels of...

Abstract Background: Inactivation of tumor suppressor genes can cause irreversible uncontrolled growth. PTEN is a tumor suppressor gene and its polymorphism (IVS4) role in breast cancer was investigated in this study. Methods: Forty nine female subjects with confirmed breast cancer comprised the case group and 43 healthy women participated as a control group in this study. The PTEN polymor...

Introduction: Defects in PTEN gene play an important role in the initiation of the prostate cancer. MAGI2 is recognized as a frame which assists in stabilizing PTEN protein and enhances its tumor suppressor function. As miR-101 down-regulates MAGI2 expression, it can indirectly cause to reduce the PTEN activity. Methods:LnCap, PC3 and DU-145 prostate cancer cell lines were studied in order to ...
