A hormone is a chemical released by one or more cells that affects cells in other parts of the organism. Only a small amount of hormone is required to alter cell metabolism. It is essentially a chemical messenger that transports a signal from one cell to another.

MIT study shows that SIRT1 gene plays key role in controlling circadian rhythms

Human sleeping and waking patterns are largely governed by an internal circadian clock that corresponds closely with the 24-hour cycle of light and darkness. This circadian clock also controls other body functions, such as metabolism and temperature regulation.

Chemical hormone released due to stress can trigger mechanism for late onset of Alzheimer's disease

A chemical hormone released in the body as a reaction to stress could be a key trigger of the mechanism for the late onset of Alzheimer's disease, according to a study by researchers at Temple University.

British post-menopausal women less likely to access appropriate treatment for vaginal atrophy

New data, published today in Menopause International, suggests that post-menopausal women in Britain are experiencing less sex, and less satisfying sex compared to their European and North American counterparts1, because they are considerably less likely to access appropriate treatment for a common, taboo condition called vaginal atrophy1.

Research: Fetal exposure to BPA causes inflammation in fat tissues after birth

New research suggests that fetal exposure to the common environmental chemical bisphenol A, or BPA, causes increased inflammation in fat tissues after birth, which can lead to obesity and metabolic syndrome. Results of the animal study were presented Monday at The Endocrine Society's 95th Annual Meeting in San Francisco.

AACE applauds the American Medical Association for recognizing obesity as disease state

The American Association of Clinical Endocrinologists (AACE) applauds the American Medical Association (AMA) House of Delegates for its action today to approve a resolution recognizing obesity as a disease state requiring a range of interventions to advance obesity treatment and prevention. AACE, the sponsor of the resolution, was joined by specialty and state medical societies in advocating for recognition of obesity as a disease state, including The Endocrine Society, American College of Cardiology, American College of Surgeons, American Urological Association, and the Texas State Delegation among many others.

Stress exposure may be associated with increased risk of aggressive breast cancer

Local chemical signals released by fat cells in the mammary gland appear to provide a crucial link between exposure to unrelenting social stressors early in life, and the subsequent development of breast cancer, researchers from the University of Chicago report in the July 2013 issue of the journal Cancer Prevention Research.

Exposing tissue to low levels of BPA linked to greater incidence of prostate cancer

Exposing developing tissue to low levels of the plastic bisphenol A, commonly known as BPA, is linked to a greater incidence of prostate cancer in tissue grown from human prostate stem cells, a new study finds. The results were presented Monday, June 17, at The Endocrine Society's 95th Annual Meeting in San Francisco.

Study: Timing of calcium, vitamin D supplementation affects skeletal adaptations to exercise training

Taking calcium and vitamin D before exercise may influence how bones adapt to exercise, according to a new study. The results will be presented on Tuesday at The Endocrine Society's 95th Annual Meeting in San Francisco.

Hormone treatment to halt puberty in transgender adolescents is safe and effective

Hormone treatment to halt puberty in adolescents with gender identity disorder does not cause lasting harm to their bones, a new study finds. The results were presented today at The Endocrine Society's 95th Annual Meeting in San Francisco.

DTE from animal thyroid glands is a safe alternative to T4 therapy in hypothyroid patients

Desiccated thyroid extract (DTE), derived from crushed preparations of animal thyroid glands, is a safe and effective alternative to standard T4 therapy in hypothyroid patients, a new study finds. The results will be presented Monday at The Endocrine Society's 95th Annual Meeting in San Francisco.

FGF21 endocrine hormone which reduces glucose levels also protects against cardiac diseases in mice

A research group has found that FGF21, an endocrine factor which reduces glucose levels, protects against cardiac diseases in mice. The research, published online on the journal Nature Communications, was led by Francesc Villarroya, professor from the Department of Biochemistry and Molecular Biology of the UB and Director of the Institute of Biomedicine of the University of Barcelona (IBUB), affiliated centre with the campus of international excellence BKC.

Fetal exposure to BPA lowers testicular hormone in newborn boys

A new study links fetal exposure to a common chemical pollutant, bisphenol A (BPA), to defects of a testicular hormone in newborn boys with undescended testicles. The results, which were presented Monday at The Endocrine Society's 95th Annual Meeting in San Francisco, suggest yet another potential harmful effect of BPA, which is widely used in many plastics, liners of food cans and dental sealants.

Missing brain enzyme increases concentrations of protein related to pain-killer addiction

A missing brain enzyme increases concentrations of a protein related to pain-killer addiction, according to an animal study. The results will be presented Monday at The Endocrine Society's 95th Annual Meeting in San Francisco.

Women with polycystic ovary syndrome lose more weight when they take two drugs

Women with polycystic ovary syndrome, or PCOS, lost significantly more weight when they took two drugs that are traditionally used to treat diabetes, rather than either drug alone, a study from Slovenia demonstrates. The results will be presented Monday at The Endocrine Society's 95th Annual Meeting in San Francisco.

University researchers investigate the role of corticosterone in signaling fetal distress

A University of Calgary researcher has identified how a steroid hormone may indicate infant distress during labour and delivery. The study, published by PLOS ONE this month, suggests that a full-term, healthy baby preferentially secretes a different stress hormone than its mother does. That stress hormone, corticosterone, has not been previously studied in human development.

kisspeptin hormone effectively induces egg maturation during infertility treatment, shows study

The naturally occurring hormone kisspeptin effectively induces egg maturation during infertility treatment, according to a clinical in vitro fertilization (IVF) study. The results were presented Monday at The Endocrine Society's 95th Annual Meeting in San Francisco.

Scientists discover molecular pathway that can prevent death of oocytes due to chemotherapy

Young women who have cancer treatment often lose their fertility because chemotherapy and radiation can damage or kill their immature ovarian eggs, called oocytes. Now, Northwestern Medicine- scientists have found the molecular pathway that can prevent the death of immature ovarian eggs due to chemotherapy, potentially preserving fertility and endocrine function.

Overweight women who skip breakfast experience acute insulin resistance

Overweight women who skip breakfast experience acute, or rapid-onset, insulin resistance, a condition that, when chronic, is a risk factor for diabetes, a new study finds. The results, which were presented Sunday at The Endocrine Society's 95th Annual Meeting in San Francisco, suggest that regularly skipping breakfast over time may lead to chronic insulin resistance and thus could increase an individual's risk for type 2 diabetes.

Vitamin D deficiency can increase asthma and allergy risk in obese children and teenagers

One reason why obese children and teenagers are more likely to have hard-to-control asthma and allergies may be vitamin D deficiency, a new study finds. Results of the study will be presented Tuesday at The Endocrine Society's 95th Annual Meeting in San Francisco.
