New toxicity test could cut animal testing
To test whether chemicals are toxic to humans, researchers need to use liver cells that have been freshly harvested from mice or other mammals. A new collection of stable cell lines, described in BMC Biotechnology this week, could reduce the numbers of animals needed in such experiments. The MMH-GH cell lines are derived from the liver cells of... view more... (2004-03-17)
Liking sweets makes sense for kids
As any parent knows, children love sweet-tasting foods. Now, new research from the University of Washington and the Monell Center indicates that this heightened liking for sweetness has a biological basis and is related to children's high growth rate. view more (2009-03-19)
Long-term hormone replacement therapy increases breast cancer risk
"Are you taking or did you take hormones? If yes, which hormone medication and for how long? When did you stop taking hormone replacement medication?" 3,464 breast cancer patients and 6,657 healthy women between the ages of 50 and 74 years participated in a large survey and elicited detailed information about hormone replacement... view more...

Study links obesity to elevated risk of ovarian cancer
A new epidemiological study has found that among women who have never used menopausal hormone therapy, obese women are at an increased risk of developing ovarian cancer compared with women of normal weight. view more (2009-01-05)

Dartmouth researchers show effects of low dose arsenic on development
A team of Dartmouth Medical School (DMS) researchers has determined that low doses of arsenic disrupt the activity of a hormone critical in development. view more (2007-11-15)
Thyroid hormone, brain development, and behavior
Dr. Bjorn Vennstrom and colleagues in Spain and at the Karolinska Institute (Sweden) have identified novel neural functions of thyroid hormone (TH), revealing that it is required during discrete periods of brain development to confer "normal" behavior. view more (2005-08-30)
INCREASED MORTALITY FROM IMPAIRED PITUITARY GLAND FUNCTION (p 425)
Patients with impaired function of the pituitary gland have increased death rates associated with vascular and respiratory disease, conclude authors of a study published in this week’s issue of THE LANCET. Four previous retrospective studies have reported premature death in patients with hypopituitarism (impairment of the pituitary gland... view more... (2001-02-07)
Protein found to control tumor growth in certain breast cancers
This protein was previously thought to play a role solely in the innate immune system's response to bacterial infection. view more (2006-02-01)
LA BioMed study finds hormone therapy increases frequency of abnormal mammograms, breast biopsies
Combined hormone therapy appears to increase the risk that women will have abnormal mammograms and breast biopsies, and it may decrease the effectiveness of both methods for detecting breast cancer. view more (2008-02-26)
Hormone therapy boosts sexual interest but not memory, study finds
Hormone therapy in early post-menopause increases sexual interest, but does not improve memory, according to a study in the Sept. 25 issue of the journal Neurology. view more (2007-09-25)
Blocking protein kills prostate cancer cells, inhibits tumor growth, Jefferson scientists find
Researchers at Jefferson's Kimmel Cancer Center in Philadelphia have shown that they can effectively kill prostate cancer cells in both the laboratory and in experimental animal models by blocking a signaling protein that is key to the cancer's growth. view more (2008-02-28)
Low blood levels of vitamin D may be associated with depression in older adults
Older adults with low blood levels of vitamin D and high blood levels of a hormone secreted by the parathyroid glands may have a higher risk of depression, according to a report in the May issue of Archives of General Psychiatry, one of the JAMA/Archives journals. view more (2008-05-06)
Scientists find hormone activity explains adolescent mood swings
The "raging hormones" of puberty are known to produce mood swings and stress for most teenagers, making it difficult to cope with this period of life. Until now, the specific causes of pubertal anxiety have not been identified, making it harder to understand and treat adolescent angst. view more (2007-03-12)
Growth hormone is used to treat twice as many short boys than girls in the US and Asia
Boys are twice as likely as girls in the U.S. and Asia (mostly Japan) to receive recombinant human growth hormone (rhGH) for growth hormone deficiency, illnesses that affect height, and short stature of a non-medical nature. view more (2008-04-18)
Cicardian system suffers and protects from prenatal cocaine exposure
Researchers from Boston University School of Medicine (BUSM) have shown that prenatal cocaine exposure in zebrafish (which share the majority of the same genes with humans) can alter neuronal development and acutely dysregulate the expression of circadian genes and those affecting melatonin signaling, growth and neurotransmission. view more (2007-07-11)
Shorter nightly sleep in childhood may help explain obesity epidemic
Soaring levels of obesity might be linked to children sleeping fewer hours at night than they used to, claims a researcher in the Archives of Disease in Childhood. view more (2006-10-19)
Appetite-stimulating hormone is first potential medical treatment for frailty in older women
Older women suffering from clinical frailty stand to benefit from the first potential medical treatment for the condition, according to a study presented today by Penn Medicine researchers at ENDO, The Endocrine Society's 91st Annual Meeting. view more (2009-06-12)
Researchers uncover how prostate cancer cells defy death
New findings about how prostate cancer cells are able to resist hormone treatment and defy death may lead to more effective drug treatments. view more (2006-07-31)
Early Promise Of New Treatment For Type 2 Diabetes (p 824)
Authors of a pilot study in this week's issue of THE LANCET suggest that a naturally occurring intestinal hormone could be beneficial for the future treatment of type 2 diabetes. Type 2 diabetes affects an estimated 10% of adults over 60 years of age, and has recently been reported in teenage children. Treatment for the disorder usually includes... view more... (2002-03-06)
