Scientists uncover new key to the puzzle of hormone therapy and breast cancer
The use of postmenopausal hormone therapy has decreased over time in the United States, which researchers suggest may play a key role in the declining rate of atypical ductal hyperplasia, a known risk factor for breast cancer. view more (2009-11-09)
Why prostate cancer patients fail hormone deprivation therapy
The hormone deprivation therapy that prostate cancer patients often take gives them only a temporary fix, with tumors usually regaining their hold within a couple of years. view more (2009-01-05)
Effect of hormone therapy on risk of heart disease may vary by age and years since menopause
Secondary analyses of findings from the Womenˇ¦s Health Initiative (WHI) suggest that women who begin hormone therapy within 10 years of menopause may have less risk of coronary heart disease (CHD) due to hormone therapy than women farther from menopause. view more (2007-04-04)
Ethnic variations in hormone levels may cause differences in breast cancer risk
Researchers have known that a woman's natural hormone levels can affect her risk of developing breast cancer. A new study from the University of Southern California (USC) has found that the natural levels of estrogens in post-menopausal women varies by ethnicity and race, and may explain the differences in the groups' breast cancer rates. view more (2006-10-10)
Found: Key 'go between' in heart disease
Medical researchers at UNSW have shed light on a little-known mechanism involved in the thickening of arteries, a process associated with heart disease. view more (2006-03-15)
Study identifies potential 'safe period' for hormone replacement use
A new study makes important new findings on the role of hormone use on the risk of breast cancer, confirming that the use of estrogen plus progesterone increases the risk of both ductal and lobular breast cancer far more than estrogen-only; suggesting a two-year "safe" period for the use of estrogen and progesterone; and finding that the... view more...

Women on hormone therapy regain emotion response
Older women on hormone therapy are more sensitive to negative events, confirming speculation that age-related estrogen loss affects the brain's ability to process emotion, an Oregon Health & Science University study shows. view more (2006-10-17)
Longer-lived rodents have lower levels of thyroid hormone
The thyroid may play an important role in longevity, with longer-lived rodents showing significantly lower levels of a thyroid hormone that speeds metabolism, a new study has found. view more (2006-10-10)
Scientists Identify Bovine Gene Regulating Milk Production
MTT Agrifood Research Finland and the University of Lie'ge, Belgium, have worked together successfully in locating a gene that regulates total yield and protein and fat content of milk. The scientists found a variation in the growth hormone receptor gene in the bovine chromosome 20. The variation in the receptor gene is associated with a major... view more... (2003-02-20)
Salk scientists untangle steroid hormone signaling in plants
When given extra shots of the plant steroid brassinolide, plants "pump up" like major league baseball players do on steroids. view more (2006-05-04)
How DDT metabolite disrupts breast cancer cells
Research has shown that the main metabolite of the insecticide DDT could be associated with aggressive breast cancer tumours, but there has been no explanation for this observation to date. Now a report published in the open access journal Breast Cancer Research shows how DDT could act to disrupt hormone-sensitive breast cancer cells. view more (2008-02-14)
Computational analysis shows that plant hormones often go it alone
or years, debate swirled around whether pathways activated by growth-regulating plant hormones converge on a central growth regulatory module. view more (2006-08-11)
Smoking damages the placenta and reduces foetal growth
Dr Peter Hindmarsh (University College, London), at the British Endocrine Societies 2003 meeting, will reveal new evidence that smoking when pregnant causes damage to the placenta and reduced birth weight. His team found that nutrient delivery to the baby was restricted and levels of an important developmental hormone, IGF-1, were reduced, causing... view more... (2003-03-19)
Hormone helps mice 'hibernate,' survive starvation
A key hormone enables starving mice to alter their metabolism and "hibernate" to conserve energy, revealing a novel molecular target for drugs to treat human obesity and metabolic disorders, UT Southwestern Medical Center researchers have found. view more (2007-06-06)
Estrogen therapy could be dangerous for women with existing heart risk
Hormone therapy could accentuate certain pre-existing heart disease risk factors and a heart health evaluation should become the norm when considering estrogen replacement, new research suggests. view more (2008-11-26)
Fat tissue-derived hormone leptin increases e-cadherin expression, obesity-breast cancer link noted
Being obese increases the risk of breast cancer in post-menopausal women, shortens the time between return of the disease and lowers overall survival rates. view more (2007-04-30)
Asian Spice Could Reduce Breast Cancer Risk in Postmenopausal Women Exposed to Hormone Replacement Therapy, MU Study Finds
Previous studies have found that postmenopausal women who have taken a combined estrogen and progestin hormone replacement therapy have increased their risk of developing progestin-accelerated breast tumors. view more (2009-07-14)
Preclinical study shows chronic stress agitates ovarian cancer; reducing stress slows tumor growth
When mice with ovarian cancer are stressed, their tumors grow and spread more quickly, but that effect can be blocked using a medication commonly prescribed for heart disease. view more (2006-07-24)
New compound 'highly efficacious' at reducing human tumour growth
Innsbruck, Austria: Treatment with a new dual cell cycle and angiogenesis pathway inhibitor blocks VEGF-induced vascular permeability, inhibits tumour angiogenesis and induces apoptosis in human tumour models said Dr Gerhard Siemeister of Schering AG, Corporate Research, Berlin speaking at the 18th meeting of the European Association of Cancer... view more...

New study suggests link between environmental toxins and early onset puberty in girls
Although scientists have speculated over the negative effects of environmental toxins for years, new data suggest that certain environmental toxins may disrupt the normal growth and hormonal development of girls. view more (2008-02-07)
