OBJECTIVE
Using a nested case-referent design we evaluated the relationship between plasma levels of six carotenoids, alpha-tocopherol, and retinol, sampled before diagnosis, and later breast cancer risk.
METHODS
In total, 201 cases and 290 referents were selected from three population-based cohorts
In an earlier study, we have observed an increase of alpha-tocopherol in breast cancer patients treated with third-generation aromatase inhibitors that was related to tamoxifen withdrawal. We report here the results of measurement of alpha-tocopherol in erythrocytes and alpha-tocopherol/cholesterol
The study of the relationship between dietary intake of vitamin E and the risk of breast cancer has not yielded definite conclusions with respect to causality, possibly due to methodological issues inherent to nutritional epidemiology. To avoid the pitfalls of dietary recalls, alpha-tocopherol
The serum levels of vitamin A (retinol), vitamin E (alpha-tocopherol), cholesterol and triglycerides were studied in a group of 40 women who had been diagnosed as having breast cancer, and they were compared to the levels found in a group of 30 healthy women. Our results indicate that the only
Combination-based chemotherapies have been the standard treatment for multiple solid tumors since the 1960s. Combined therapies where both agents have toxicity results in dose-limiting effects. α- tocopherol succinate (TS) is an analogue of vitamin E that exhibits antitumor properties in the absence
Breast cancer is the most common malignancy among women and has an age-specific incidence profile. Over the last decade, many studies have demonstrated the anticancer activity of α-tocopherol, the main and most active form of natural vitamin E. α-Tocopherol-associated protein (TAP) was found to be
To evaluate relationships of serum carotenoids, alpha-tocopherol, selenium, and retinol with breast cancer prospectively, we conducted a case-control study nested in a cohort from the Breast Cancer Serum Bank in Columbia, Missouri (United States). Women free of cancer donated blood to this bank in
Cancer cells are known to exhibit different hallmarks compared with normal cells. Therefore, targeting these features may improve the response to cancer therapy. In this study, we provided direct evidence that the α-tocopherol derivative ESeroS-GS inhibited the viability, migration, and invasion of
BACKGROUND
The role of vitamin E in breast cancer prevention and treatment has been widely investigated, and the different tocopherols that comprise this nutrient have been shown to have divergent associations with cancer outcome. Our previous studies have shown that α-Tocopherol-associated protein
The present study evaluates the prophylactic efficacy of α-tocopherol (α-TOH), resveratrol (RES), and coenzyme Q10 (CoQ10) co-loaded self-nanoemulsifying drug delivery system (α-TOH-RES-CoQ10 SNEDDS) in 7,12-Dimethylbenz[a]anthracene (DMBA) induced breast cancer model. SNEDDS formulation components
Triple‑negative breast cancers (TNBCs) lack the estrogen receptor, progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2). Therefore, hormone or targeted therapies are not effective in the treatment of TNBC and thus the development of novel therapeutic strategies is crucial.
OBJECTIVE
Plasma antioxidants are supposed to be directly related to breast cancer risk. However, the results remain inconsistent. Herein, we carried this meta-analysis to comprehensively summarize the associations between plasma retinol, vitamins A, C and α-tocopherol and breast cancer
In the present study, pH-triggered polymeric micelle composed of alpha- tocopherol (TOC) and heparin (HEP) was developed and loaded with docetaxel (DTX). The amphiphilic copolymer was synthesized by grafting TOC onto HEP backbone by a pH-cleavable bond. DTX-loaded micelles were characterized in
Vitamin E, best known as a potent antioxidant, has been shown to have other functions that are not mediated by this activity. Recent reports have suggested that vitamin E may inhibit smooth muscle cell and also cancer cell growth. We have studied the effect of dl-alpha-tocopherol (vitamin E) on a
In this study, tocopherol based polymeric micelles were successfully prepared to enhance the anticancer effect of fisetin (FIS) in breast cancer cells.
The drug-loaded carrier was characterized in terms of physicochemical and in vivo parameters.
Compared to FIS, FIS-TPN showed higher cellular uptake
