The value of 6-phosphogluconate dehydrogenase (6-PGDH) activity as a cytosolic marker of tumour cellularity has been assessed, together with its use as a prognostic indicator for primary breast cancer in 87 patients over 4 years. 6-PGDH activity shows a good correlation with histologically-assessed
OBJECTIVE
6-phosphogluconate dehydrogenase (6PGD), a key enzyme of the oxidative pentose phosphate pathway, is involved in tumor growth and metabolism. Although high 6PGD activity has been shown to be associated with poor prognosis, its role and therapeutic value in breast cancer remain
The efficacy of the addition of prednisolone to tamoxifen as adjuvants to mastectomy in patients with primary breast cancer who were at a high risk of recurrence was investigated in a randomized trial. Primary carcinomas were collected from a series of 169 patients with loco-regional disease,
The activities of the enzymes lactate dehydrogenase, 6-phosphogluconate dehydrogenase, and phosphohexose isomerase in primary human breast cancer biopsies are shown to be related to the time between mastectomy and recurrence of the cancer. These enzymes have higher activity in malignant breast
UNASSIGNED
The purpose of this study was to assess the expression of pentose phosphate pathway- (PPP-) related proteins and their significance in clinicopathologic factors of breast cancer.
UNASSIGNED
Immunohistochemical staining for PPP-related proteins (glucose-6-phosphate dehydrogenase [G6PDH],
Purpose. We aimed to investigate the expression of pentose phosphate pathway- (PPP-) related proteins in metastatic breast cancer and its relationship with clinicopathologic factors. Methods. Tissue samples from 126 metastatic breast cancers were included in a tissue microarray. Expression of
Fatty liver is associated with obesity and breast cancer. We used an obese rat model of mammary cancer to examine whether hepatosteatosis is modifiable by diet and associated with altered expression of hepatic lipogenic enzyme genes, thyroid hormone system genes and cholesterol metabolism-related
Postmenopausal patients with primary breast cancer were treated with tamoxifen, ethynyloestradiol or prednisolone for up to 12 days before mastectomy and the effects of pretreatments with these drugs on the activities of phosphofructokinase (PFK), 6-phosphogluconate dehydrogenase (6PGDH) and
BACKGROUND
Characterization of the pro-oxidant activity of QNACR.
OBJECTIVE
Reactive oxygen species (ROS) induce cellular damage and represent unique opportunities to kill malignant cells. In this study, we synthesized and evaluated the new compound, (E)-methyl
Most of the available human breast tumor cell lines have been derived from pleural effusions. The two cell lines herein described, BT-474 and BT-483, were derived from solid, invasive ductal breast carcinomas. Both are epithelial and neoplastic as judged by their general morphology, their fine
We found that Adriamycin increased the pentose phosphate shunt activity in both Adriamycin-sensitive (WT) and Adriamycin-resistant (ADRR) human breast cancer MCF-7 cells. In contrast, hydrogen peroxide and cumene hydroperoxide markedly stimulated pentose-shunt activity in ADRR but only moderately
