Estrogen can reduce stroke damage by inactivating protein
Estrogen can halt stroke damage by inactivating a tumor-suppressing protein known to prevent many cancers, Medical College of Georgia researchers say. view more (2009-07-17)
Estrogen-Dependent Switch Tempers Killing Activity of Immune Cells
The sex hormone estrogen tempers the killing activity of a specific group of immune cells, the cytotoxic T cells (CTLs), which are known to attack tumor cells and cells infected by viruses. view more (2009-08-10)
Brain memory area modifies its wiring diagram during the female cycle
Researchers at Northwestern University and Columbia University have found that "wiring" in female rat brain memory area expands and retracts in relation to the amount of estrogen present during the estrous/menstrual cycle. view more (2005-11-15)
Jefferson Scientists Identify Gene Mutation Potentially Involved in Breast Cancer Initiation
Researchers at Jefferson Medical College and the Kimmel Cancer Center at Thomas Jefferson University in Philadelphia and at the Albert Einstein College of Medicine in New York have found evidence suggesting that a mutation in a gene that normally helps block the formation of breast tumors could play a role in the initiation of a major form of... view more...

Ultra low-dose estrogen shown safe for post-menopausal women
A study led by researchers at the San Francisco VA Medical Center has shown that extremely low doses of estrogen had no ill effects on the cognitive abilities or general health of older women over the course of two years. view more (2006-07-17)
Estrogen plays different role during stress in black and white teens
Estrogen seems to play a different role during stress in black and white girls, a difference that may help explain higher cardiovascular disease rates in blacks, researchers have found. view more (2006-06-26)
Benefit of chemotherapy in breast cancer depends on estrogen-receptor status
When it comes to chemotherapy treatment for women whose breast cancer has spread to their lymph nodes, the estrogen status of their tumors matters. view more (2006-04-12)
Estrogen-progestin menopausal hormone therapy and risk of lobular and tubular breast cancer
Estrogen-progestin menopausal hormone therapy is associated with a more than two-fold higher relative risk of developing lobular cancer or tubular cancer than of developing ductal cancer. view more (2006-02-17)
Complex Changes in the Brain's Vascular System Occur after Menopause
Many women experience menopausal changes in their body including hot flashes, moodiness and fatigue, but the changes they don't notice can be more dangerous. view more (2008-06-17)
Researchers may have unlocked the mechanisms that silence the estrogen receptor gene alpha during breast cancer
The mechanisms that silence the estrogen receptor gene alpha (ER-α) in certain breast cancer cell lines may be closer to being unlocked. view more (2007-08-20)
Improved estrogen reception may sharpen fuzzy memory
Estrogen treatments may sharpen mental performance in women with certain medical conditions, but University of Florida researchers suggest that recharging a naturally occurring estrogen receptor in the brain may also clear cognitive cobwebs. view more (2008-07-30)
Dual role in breast tissue for a protein involved in leukemia
A protein known to play a role in growth of some types of leukemia appears to have a mixed function in breast cancer development, say researchers from the Lombardi Comprehensive Cancer Center at Georgetown University Medical Center (GUMC). view more (2009-06-15)
Cancer conflict with chemotherapy treatment
Women under the age of forty with breast cancer who are given drugs in addition to lumpectomies or radiotherapy, known as adjuvant chemotherapy, may not be benefiting from these drugs. view more (2007-10-11)
Researchers zero in on estrogen's role in breast-cancer cell growth
Why do estrogen-dependent breast-cancer cells grow and spread rapidly? Researchers at the University of Illinois at Urbana-Champaign say it may be because estrogen virtually eliminates levels of a vitally important regulatory protein. view more (2005-09-12)
Preventium is 'where the prevention of breast and prostate cancer begins'
Dr. Ercole Cavalieri and Dr. Eleanor Rogen of the University of Nebraska Medical Center, Eppley Institute for Research in Cancer, located in Omaha, Nebraska, have identified the triggering mechanism by which breast and prostate cancer cells begin. view more (2009-03-17)
