Hormone News and Research

RSS

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.

Researchers discover unknown mechanism that promotes growth and spread of cancer

Tiny vesicles released by tumors cells are taken up by healthy immune cells, causing the immune cells to discharge chemicals that foster cancer-cell growth and spread, according to a study by researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James) and at Children's Hospital in Los Angeles.

Surgery advised in face of uncertain sinus sampling result in Cushing patients

Surgeons should consider transsphenoidal surgery in patients with Cushing disease caused by adrenocorticotropic hormone overproduction, almost irrespective of the results of inferior petrosal sinus sampling, say US researchers.

Combination of estrogen and MPA increases synapses in the prefrontal cortex

A new study of aged female rats found that long-term treatment with estrogen and a synthetic progesterone known as MPA increased levels of a protein marker of synapses in the prefrontal cortex, a brain region known to suffer significant losses in aging.

Roux-en-Y gastric bypass surgery induces changes in the gut microbiota

Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, finds that gastric bypass surgery induces changes in the gut microbiota and peptide release that are similar to those seen after treatment with prebiotics.

Hormone therapy still an acceptable treatment for menopausal symptoms: New joint statement

After 10 years of debate regarding the risks and benefits of hormone therapy, 15 top medical organizations have come together to issue a statement of agreement regarding the benefits of hormone therapy for symptomatic menopausal women. It was July 9, 2002, when the controversial, highly publicized Women's Health Initiative (WHI) published its assessment of hormone therapy for the prevention of chronic disease and concluded that risks exceeded benefits.

Adiponectin reduces depression-like symptoms in mice

A hormone with anti-diabetic properties also reduces depression-like symptoms in mice, researchers from the School of Medicine at the UT Health Science Center San Antonio reported today.

Researchers use metal complexes to modify peptide hormones

Researchers at the RUB and from Berkeley have used metal complexes to modify peptide hormones. In the Journal of the American Chemical Society, they report for the first time on the three-dimensional structure of the resulting metal-peptide compounds.

New somatostatin vaccines promote weight loss

New vaccines promote weight loss. A new study, published in BioMed Central's open access journal, Journal of Animal Science and Biotechnology, assesses the effectiveness of two somatostatin vaccinations, JH17 and JH18, in reducing weight gain and increasing weight loss in mice.

Study determines risk of young-onset breast cancer after use of ovulation-stimulating fertility drugs

Women using fertility drugs who did not conceive a 10-plus week pregnancy were at a statistically significant reduced risk of breast cancer compared to nonusers; however, women using the drugs who conceived a 10-plus week pregnancy had a statistically significant increased risk of breast cancer compared to unsuccessfully treated women, but a comparable risk to nonusers, according to a study published July 6 in the Journal of The National Cancer Institute.

Vitrolife's EmbryoGlue medium increases implantation and pregnancy rates

In a study presented at the on-going ESHRE conference in Istanbul, Vitrolife's patent protected medium EmbryoGlue has once again been proven to increase both implantation and pregnancy rates, regardless of hormone stimulation of the endometrium or not.

Italy's first successful pregnancy and delivery following transplantation of ovarian tissue

Although the first successful preservation of fertility from the freezing, thawing and grafting of ovarian tissue was reported eight years ago, the technique has remained experimental and confined to a few specialist centres. Now, with the announcement of a first pregnancy (and subsequent live birth) in Italy following the transplantation of ovarian tissue, there are indications that fertility preservation is moving into the mainstream of reproductive medicine and into a greater number of centres.

Study examines how cells exploit gene sequences to cope with toxic stress

Toxic chemicals wreak havoc on cells, damaging DNA and other critical molecules. A new study from researchers at MIT and the University at Albany reveals how a molecular emergency-response system shifts the cell into damage-control mode and helps it survive such attacks by rapidly producing proteins that counteract the harm.

Researchers identify mechanism responsible for inhibition of AMPK activity in the hypothalamus

In the complex chain of molecular events that underlie eating behaviors and body weight, the AMP-activated protein kinase (AMPK) enzyme has proven to be a critical link.
