Mutant PTEN in Cancer: Worse Than Nothing
نویسندگان
چکیده
Tumor suppressors block the development of cancer and are often lost during tumor development. Papa et al. show that partial loss of normal PTEN tumor suppressor function can be compounded by additional disruption caused by the expression of inactive mutant PTEN protein. This has significant implications for patients with PTEN gene mutations.

ارتباط پلی مرفیسم IVS4 ژن PTEN با سرطان پستان زنان ایرانی
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...
متن کاملPTEN Gene Expression and Its Association with rs10490920 SNP in Breast Cancer
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...
متن کاملVandetanib is effective in EGFR-mutant lung cancer cells with PTEN deficiency.
The effectiveness of vandetanib, an agent that targets RET, VEGFR and EGFR signaling, against EGFR-mutant lung cancer cells with PTEN loss was investigated. Two EGFR mutant non-small cell lung cancer (NSCLC) cell lines, PC-9 (PTEN wild type) and NCI-H1650 (PTEN null), were used. We transfected an intact PTEN gene into H1650 cells and knocked down PTEN expression in PC-9 cells using shRNA. The e...
متن کاملبررسی تغییرات بیانmiR-101و ارتباط آن با میزان بیان ژن‌های سرکوب‌کننده تومور PTENو MAGI2در سه رده سلولی سرطان پروستات
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 ...
متن کاملTumor Spectrum, Tumor Latency and Tumor Incidence of the Pten-Deficient Mice
BACKGROUND Pten functionally acts as a tumor suppressor gene. Lately, tissue-specific ablation of Pten gene in mice has elucidated the role of Pten in different tumor progression models. However, a temporally controlled Pten loss in all adult tissues to examine susceptibility of various tissues to Pten-deficient tumorigenesis has not been addressed yet. Our goal was to explore the genesis of Pt...
