Regulation Of Micrornas By 17Β-Estradiol In The Aging Female Brain, Yathindar Satya Giffin-Rao

Dissertations

Hormone Therapy (HT) is used to increase the 17β-estradiol (E2) levels in women who are going through the menopausal transition to alleviate the negative symptoms associated with menopause and decrease the risk of chronic diseases. Clinical and basic science research had previously shown that HT provided protection from cognitive decline and reduced the risk of dementia. However the Women's Health Initiative (WHI) clinical trial demonstrated that HT had no beneficial effects for cognitive decline and, in some cases increased the risk of dementia in post-menopausal women. However, further analysis of WHI data showed that when HT was given to women …

Mechanisms Of Estrogen Receptor Alternative Splicing And The Consequences For Aging In The Female Brain, Cody Lee Shults

The advances in healthcare and scientific knowledge have resulted in longer life expectancies in women. These advanced ages in women now means that they are experiencing the effects of age-related changes in the body for much longer periods of time, mainly reproductive senescence, resulting in the loss of circulating ovarian hormones. The age at which menopause occurs has not changed, resulting in women now living over a third of their lives in a postmenopausal state.

The major circulating estrogen produced by the ovaries, 17β-estradiol (E2), has many homeostatic effects in the body like neuroprotection and cardioprotection. Hormone replacement therapy (HT) …
