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.

Beta blockers do not reduce risk of colorectal cancer

A new study has found that, contrary to current thinking, taking beta blockers that treat high blood pressure does not decrease a person's risk of developing colorectal cancer. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the study also revealed that even long-term use or subtypes of beta blockers showed no reduction of colorectal cancer risk.

Researchers discover protein that regulates activation of brown fat

Scientists have identified a protein which regulates the activation of brown fat in both the brain and the body's tissues. Their research, which was conducted in mice, was published today, Friday 11 May, in the journal Cell.

Checking for specific genetic variants can help identify women at high risk of PND

Researchers at Warwick Medical School have discovered a way of identifying which women are most at risk of postnatal depression (PND) by checking for specific genetic variants.

Research with infant twins shows that environmental conditions determine testosterone levels

By comparing the testosterone levels of five-month old pairs of twins, both identical and non-identical, University of Montreal researchers were able to establish that testosterone levels in infancy are not inherited genetically but rather determined by environmental factors. "Testosterone is a key hormone for the development of male reproductive organs, and it is also associated with behavioural traits, such as sexual behaviour and aggression," said lead author Dr. Richard E. Tremblay of the university's Research Unit on Children's Psychosocial Maladjustment.

KLF15 molecule inhibits action of estrogen in the endometrium

Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered a molecule that inhibits the action of estrogen. This female hormone plays a key role in the growth, maintenance and repair of reproductive tissues and fuels the development of endometrial and breast cancers.

BP sunscreens may increase risk of endometriosis in women

Scientists are reporting a possible link between the use of sunscreen containing a certain ingredient that mimics the effects of the female sex hormone estrogen and an increased risk of being diagnosed with endometriosis, a painful condition in which uterine tissue grows outside the uterus. They describe the report, published in ACS' journal Environmental Science & Technology, as the first to examine whether such a connection may exist.

Positive results from PROLOR Biotech's hGH-CTP Phase II trial for growth hormone deficiency

PROLOR Biotech, Inc. today reported top-line results from a Phase II four-month treatment extension study of hGH-CTP, its long-acting version of human growth hormone, in growth hormone deficient adults.

Researchers discover how diabetes affects specific brain area leading to memory loss

Badly controlled diabetes are known to affect the brain causing memory and learning problems and even an increased incidence of dementia, although how this occurs is not clear.

Researchers separate low and high-PSA prostate cancer cells

Prostate cancer cells that defy treatment and display heightened tumor-generating capacity can be identified by levels of prostate specific antigen (PSA) expressed in the tumor cells, a research team led by scientists at The University of Texas MD Anderson Cancer Center reports in the May 3 edition of Cell Stem Cell.

LRI applauds ACR colleagues for new lupus nephritis guidelines

The Lupus Research Institute (LRI) applauds our colleagues at the American College of Rheumatology (ACR) for issuing new guidelines to help healthcare professionals screen, diagnose and treat lupus nephritis, a type of kidney disease associated with lupus. Available on the ACR website, the new guidelines are just published in the April 2012 issue of Arthritis Care & Research.

Research identifies molecular trigger of fibroid uterine tumors

Fibroid uterine tumors affect an estimated 15 million women in the United States, causing irregular bleeding, anemia, pain and infertility. Despite the high prevalence of the tumors, which occur in 60 percent of women by age 45, the molecular cause has been unknown.

Dilp8 provides an important signal to slow body growth and delay insect development

Two independent groups of researchers have identified a hormone that is responsible for keeping the growth and development of insects on track. The results, which are reported in the journal Science, suggest that Dilp8 provides an important signal to slow body growth and delay insect development.

MicroRNAs in breast cancer play a role in development of resistance to tamoxifen

Many breast cancer patients are treated with a drug called tamoxifen. The substance blocks the effect of estrogen and thus suppresses the growth signals of this hormone in cancer cells. When resistance to the drug develops, tumor cells change their growth program: They change their behavior and shape, become more mobile and also adopt the ability to invade surrounding tissue. Scientists working with PD (Associate Professor) Dr. Stefan Wiemann of the German Cancer Research Center (DKFZ) have now also observed these changes in tamoxifen resistant breast cancer cells.
