The gamma-glutamyl cycle catalyzed by gamma-glutamyl transferase (GGT) plays an important role in glutathione (GSH) homeostasis in the cell. In cells continuously exposed to the drug, the main phase of the enzymatic detoxification is the conjugation of the drug with GSH catalyzed by Different etiological pathways may precede development of specific breast cancer subtypes and impact prevention or treatment strategies. We investigated the association between gamma-glutamyl transferase (GGT) and development of specific breast cancer subtypes based on oestrogen receptor (ER),
The CA 15-3 and CEA concentrations and the alkaline phosphatase (ALP) and gamma-glutamyl transferase (Gamma GT) activities of serum from 78 patients with breast cancer have been measured. The patients included 27 with localised breast cancer, 19 who had been treated for breast cancer but were now
BACKGROUND
It has been reported that there is an increased risk of cancer in individuals with elevated levels of serum gamma-glutamyl transferase (GGT).
METHODS
In the Guernsey Breast Cancer Cohort Study, GGT was measured in sera from 1803 normal women. Among these women, 251 subsequently developed
Most of the breast cancer deaths occur when cancer cells depart from their tumour of origin and spread systemically and colonise distant organs. The present study was to find out whether punarnavine, the quinolizidine alkaloid, with already proven antimetastatic effect on spontaneous B16F10
The purpose of the study was to determine the effect of adjuvant chemotherapy on liver enzymes in breast cancer patients. Furthermore, the effect of tamoxifen on liver enzymes was analyzed. Liver function tests from 194 breast cancer patients who received adjuvant chemotherapy with or without
Forty-five women with far-advanced metastatic breast cancer were treated with a combination of aminoglutethimide (AG), 1000 mg p.o. daily, and medroxyprogesterone acetate (MPA), 1500 mg p.o. daily. Of 41 patients evaluable for treatment response, there were two complete responses, five partial
Localized to cell membrane, γ-glutamyl transferase (GGT) is a reliable marker for the evaluation of cell distress occurring in several pathological conditions including obesity, metabolic syndrome, and cancer. In particular, high GGT serum levels are associated with breast cancer Eribulin is active and safe in heavily pre-treated metastatic breast cancer patients. Few safety data have been published in third line. We aimed to report the specific safety profile on third line beyond taxanes and anthracyclines in advanced breast cancer (ABC). A multicenter phase II, prospective
A mathematical model of prediction of progression was tested in patients with breast cancer employing long-term monitoring of tumor markers CEA, CA 15-3, MCA and TPA, erythrocyte sedimentation rate (FW), and the enzymes gamma-glutamyl transferase (GGT), alkaline phosphatase (ALP) and lactate
Alkaline phosphatase isoenzymes in bone and liver metastases of breast cancer were determined in 637 patients and during follow up in 116 patients, by agarose gel electrophoresis. The activity of total alkaline phosphatase, gamma glutamyl transferase, CEA and CA 15-3 was also determined. The
OBJECTIVE
To study the effect of matrine injection on preventing liver function damage of anti-tumor drugs during chemotherapy of breast cancer.
METHODS
167 times of chemotherapy were performed and divided into two groups (the control and treatment group: 86 times for the treatment one, 81 times for
Malignancy depletes host glutathione (GSH) levels to increase treatment-related toxicity and increases itself to resist the treatments. Our previous studies have shown that dietary glutamine (GLN) prevented 7,12-dimethylbenz[a]anthracene (DMBA)-induced mammary tumors through enhancing gut GSH
BACKGROUND
Studies have shown that the renin angiotensin system via angiogenesis is involved in tumor development.
OBJECTIVE
Therefore, objective of the present study was to examine the effect of perindopril on tumor growth and angiogenesis in animal models of breast cancer.
METHODS
In the present
Although nonalcoholic fatty liver disease (NAFLD) has been linked to breast cancer risk, the actual relationship remains unclear. Fatty liver index (FLI) is a noninvasive method for predicting NAFLD. We aimed to assess the association between FLI, a predictor of NAFLD, and breast
