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 identify key mechanism behind aggressive prostate cancer

A team of researchers from UC Davis, UC San Diego and other institutions has identified a key mechanism behind aggressive prostate cancer. Published on August 14 in Nature, the study shows that two long non-coding RNAs (PRNCR1 and PCGEM1) activate androgen receptors, circumventing androgen-deprivation therapy.

Managing insulin levels through meal timing boosts ovulation in women with PCOS

Polycystic Ovarian Syndrome (PCOS), a common disorder that impairs fertility by impacting menstruation, ovulation, hormones, and more, is closely related to insulin levels. Women with the disorder are typically "insulin resistant" - their bodies produce an overabundance of insulin to deliver glucose from the blood into the muscles.

Exo70 protein responsible for plasma membrane reshaping and cell movement

Both basic scientists and clinicians have an interest in how the cells of our body move. Cells must be mobile in order for organisms to grow, to heal, to transmit information internally, to mount immune responses and to conduct a host of other activities necessary for survival.

Pregnant women with thyroid hormone deficiency are 4 times likelier to produce autistic children

Pregnant women who don't make nearly enough thyroid hormone are nearly 4 times likelier to produce autistic children than healthy women, report scientists from the Houston Methodist Neurological Institute and Erasmus Medical Centre in an upcoming Annals of Neurology (online today).

Women diagnosed for menopause after breast cancer may vary with type of doctors

Hormonal treatment for breast cancer causes menopause in over 80% of women in the first year of therapy, but now new research, published in the peer-reviewed journal Climacteric, has found that how these women are diagnosed and treated for menopausal symptoms can vary substantially according to which type of doctor a woman sees.

Quality of life of young, female cancer survivors is impaired after treatment

A new study led by a University of Colorado Cancer Center member recently published in the journal Quality of Life Research reveals that in young, female cancer survivors, quality of life is significantly impaired long after treatment. The study compared 59 cancer survivors to 66 healthy controls and found that, as expected, cancer survivors showed higher stress and anxiety than the general population.

Stillbirth research: an interview with Dr Lucy Higgins, University of Manchester

Stillbirth, the birth of a baby who shows no sign of life after 24 completed weeks of pregnancy, occurs in 1 in every 200 pregnancies in the United Kingdom. That’s roughly 10 bereaved families a day.

State highlights: Accusations of fraud or abuse in disabled, rehabilitation clinics in N.Y., Mich. and Calif.

Two and a half years ago, The New York Times published an article about abusive employees who worked for the state, detailing how few employees were fired, even after the state recommended that they lose their jobs, because of weaknesses in the arbitration process, the permissive attitude of state officials and the aggressive stance of public sector labor unions -- particularly the Civil Service Employees Association. Gov. Andrew M. Cuomo promised to change all this.

Research: Chronic cocaine use may reduce body's ability to store fat

Chronic cocaine use may reduce the body's ability to store fat, new research from the University of Cambridge suggests. The scientists found that cocaine use may cause profound metabolic changes which can result in dramatic weight gain during recovery, a distressing phenomenon that can lead to relapse.

Specialized endocytocis play a crucial role in shaping cells themselves

The process cells use to 'swallow' up nutrients, hormones and other signals from their environment - called endocytosis - can play a crucial role in shaping the cells themselves, scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have found.

Tubingen researchers resolve how a plant steroid hormone makes plants grow

If one wants to better understand how plants grow, one must analyse the chemistry of life in its molecular detail. Michael Hothorn from the Friedrich-Miescher-Laboratory of the Max Planck Society in T-bingen and his team are doing just that. Their latest work now reveals that a plant membrane receptor requires a helper protein to sense a growth-promoting steroid hormone and to transduce this signal across the cell membrane.

Sericin can decrease blood glucose levels and alleviate diabetic hippocampal damage

Preliminary studies by Dr. Zhihong Chen and colleagues from Chengde Medical College have shown that sericin might improve aberrant Akt signaling, decrease heme oxygenase-1 expression in the hippocampus and cerebral cortex, and reduce the apoptosis of hippocampal neurons in diabetic rats, thus protecting the nervous system.

Autism affects men and women differently

Autism affects different parts of the brain in females with autism than males with autism, a new study reveals. The research is published today in the journal Brain as an open-access article.

Mother's perceived social status predicts child's brain development, stress indicators

A mother's perceived social status predicts her child's brain development and stress indicators, finds a study at Boston Children's Hospital. While previous studies going back to the 1950s have linked objective socioeconomic factors—such as parental income or education—to child health, achievement and brain function, the new study is the first to link brain function to maternal self-perception.

Research shows how mammalian and bacterial kingdoms interact

The bacteria Streptococcus pneumoniae harmlessly colonizes the mucous linings of throats and noses in most people, only becoming virulent when they leave those comfortable surroundings and enter the middle ears, lungs or bloodstream. Now, in research published in July in mBio, University at Buffalo researchers reveal how that happens.
