The biological effects of 17 alpha-estradiol (17 alpha-E) and its interaction with estrogen receptors were studied in the MCF-7 human breast cancer cell line. Competition for [3H]17 beta-estradiol ([3H]17 beta-E) binding shows that 17 alpha-E binds to receptor with high affinity and has a
A comparative study of the proliferative effect of 17 beta-estradiol and 17 alpha-estradiol on human estrogen-sensitive cell lines was performed. When using charcoal-dextran stripped human female sera-supplemented media the administration of the hormones, 17 alpha-estradiol at 3 X 10(-10)M, and 17
High dose estrogen therapy has been used effectively in the treatment of human breast cancer. To understand the mechanisms involved, the effects of high concentrations (5-100 microM) of estrogens were studied in estrogen receptor (ER) positive (T-47D and MCF-7) and ER negative (MDA-MB-330) human
Using a colony formation assay, the cytotoxic effects of steroids and an anti-steroid on an established human breast tumor line and two human diploid fibroblast strains were studied. Experiments involving 17 a-estradiol, 17 beta-estradiol, dexamethasone, cortisone, dihydrotestosterone, and the
The cytoplasmic estrogen receptor was measured in 9 intracranial meningiomas and 8 thymomas. The binding affinities of the estrogen receptor derived from the tumors to various estrogens and antiestrogens were compared with that observed for the receptor from rat normal uterus. The cytoplasmic
BACKGROUND
Physical activity is widely recognized as a means for the primary prevention of chronic diseases as well as in patients' treatment and rehabilitation. Moreover, activity has beneficial effects on an individual's health and well-being. Despite the benefits of regular physical activity, the
