Epidemiological evidence on the association between genetic polymorphisms in glutathione S-transferases M1 (GSTM1) and T1 (GSTT1) genes and risk of endometrial cancer (EC) has been inconsistent. In this meta-analysis, we seek to investigate the relationship between GSTM1 and GSTT1 polymorphisms and
A randomized pilot trial was performed to evaluate the feasibility of administration of glutathione (GSH, 1200 mg, i.v.) as a protector in preventing diarrhea in patients operated on for endometrial cancer and submitted to adjuvant radiotherapy of the pelvis. Diarrhea occurred in 52% of patients in
A case-control study was designed to identify associations between polymorphisms at p53, cytochrome P-450 (CYP1A1) and glutathione-S-transferases and endometrial cancer susceptibility. Among all polymorphisms analysed, an insertional variant in p53 (P53PIN3) and two polymorphisms in the 3'-end and
Antioxidant enzyme activities and lipid peroxidation were analysed in normal endometrium and endometrial cancer tissues from Finnish and Japanese patients. The catalase and glutathione peroxidase activities of normal endometrium were significantly lower in Finns than in Japanese. Lipid peroxidation
Activities of estrogen metabolism enzymes (aromatase, 2- and 4-estrogen hydroxylases, catechol-O-methyltransferase, and glutathione transferase) were studied by modern biochemical methods in tumors of patients with endometrial cancer. Relationships between enzyme activities and body weight index,
Despite the beneficial effects of tamoxifen in the treatment and prevention of breast cancer, long-term usage of this popular antiestrogen has been linked to an increased risk of developing endometrial cancer in women. One of the suggested pathways leading to the potential toxicity of tamoxifen
Endometrial cancer is a common type of malignant tumor of the human female genital tract, which typically occurs after menopause. Asian nations, including Korea, Japan and China, have a 4-5 times lower incidence than Western industrialized nations. However, in recent years, there has been a marked
OBJECTIVE
To establish the cisplatin (DDP)-resistant cell line from human endometrial cancer cell line Ishikawa and to investigate its resistant mechanism to DDP.
METHODS
A resistant endometrial cancer cell line ISH/DDP was established by gradually increasing dose of cisplatin and high-dose
OBJECTIVE
The primary objective of this study was to determine the mechanism(s) of cisplatin drug resistance in endometrial cancer cell lines. To evaluate the mechanism that gemcitabine modulates cisplatin drug resistance in endometrial cancer cell lines.
METHODS
Combination treatment was completed
OBJECTIVE
To investigate the polymorphism rates and possible roles of glutathione-s-transferase M1, T1, and P1 gene polymorphisms in the predisposition to endometrial cancer in Caucasian women.
METHODS
Serum samples and medical records were collected from 53 Caucasian women with newly diagnosed
Numerous studies have suggested that the lifetime dose of unopposed estrogen is a significant risk factor for breast and uterine cancer. Estradiol (E2) plays a putative role as a tumor promoter through interaction with estrogen receptors but can also be metabolized to redox active and/or mutagenic
OBJECTIVE
Nuclear glutathione S-transferase pi (GST7pi) has been reported to protect cancer cells against anticancer drugs. The aim of the present study was to evaluate the clinical significance of nuclear GSTpi in gynaecological cancer.
METHODS
We carried out an immunohistochemical analysis of
OBJECTIVE
Endometrial carcinoma is the most common gynecologic cancer in developed countries. Prolonged unopposed estrogen exposure has been identified as the major risk factor. The pi-class glutathione S-transferase (GSTP1) is a phase II metabolic enzyme that is important in the detoxification of a
The aim of this study was to determine whether glutathione peroxidase (GSH-Px) activity in endometrial tissue is regulated by sex hormones and to compare the GSH-Px activity of normal and cancerous endometrium. The localization of GSH-Px in human normal endometrium and endometrial cancer was
Endometrial cancer is one of the most prevalent tumors of the female reproductive system causing serious health effects to women worldwide. Although numerous studies, including analysis of gene expression profile and cellular microenvironment have been reported in this field, pathogenesis of this
