Estrogen and Antiestrogen Actions on Human Prostate Cancer: A Dissertation
Prostate cancer increases its incidence with age after men in their fifth decade as the ratio of estrogen to androgen rises. Epidemiological studies indicated that high levels of estrogens are associated with the high-risk ethnic groups for prostate cancer. Therefore estrogens may be involved in prostatic carcinogenesis. It is widely believed that the actions of estrogens are mediated by estrog...
متن کاملUnraveling estrogen action in osteoporosis.
A decrease in estrogen levels at menopause leads to a rapid loss of bone mineral density and an increase in fracture risk. For over ten years it has been known that the beneficial effects of estrogen are due in part to the ability of estrogen to suppress osteoclastogenic cytokine production in T-cells and osteoblasts. In addition to suppressing these cytokines, estrogen has been shown to induce...
متن کاملThe antiestrogen ICI 182780 disrupts estrogen receptor nucleocytoplasmic shuttling.
The mouse estrogen receptor was shown to be constantly shuttling between the nucleus and cytoplasm although under steady-state conditions it is detected predominantly in the cell nucleus in both the absence and presence of estradiol. Shuttling was demonstrated by monitoring the transfer of protein between nuclei in heterokaryons and by examining the subcellular distribution of mutant receptors....
متن کاملEstablished and forthcoming drugs for the treatment of osteoporosis.
PURPOSE OF REVIEW The aim of treatment in patients at high risk for fractures is to reduce the risk of a first or a subsequent fracture. New data are available on the antifracture effects and side-effects of antiresorptive and osteoanabolic drugs, and new emerging therapies with new modes of action are on the horizon. RECENT FINDINGS Calcium and vitamin D intake should be sufficient, but not ...
متن کاملRole of estrogen in avian osteoporosis.
One of the difficulties associated with commercial layer production is the development of osteoporosis in hens late in the production cycle. In light of this fact and because of hens' unique requirements for Ca, many studies have focused on the regulation of Ca and the role of estrogen in this process. The time course of estrogen synthesis over the productive life of hens has been well document...
