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.

Medications often prescribed for PAH could affect heart health of treated patients

A research team with the Faculty of Medicine & Dentistry at the University of Alberta reported findings that significantly improve understanding of how widely used drugs in Pulmonary Arterial Hypertension (PAH) affect the heart health of treated patients.

Stress in adolescence can cause severe mental illness in young adulthood

Working with mice, Johns Hopkins researchers have established a link between elevated levels of a stress hormone in adolescence — a critical time for brain development — and genetic changes that, in young adulthood, cause severe mental illness in those predisposed to it.

Study finds key association between Kallikrein 6 and malignant tumors

One of the most common types of brain tumors in adults, glioblastoma multiforme, is one of the most devastating. Even with recent advances in surgery, radiation and chemotherapy, the aggressive and invasive tumors become resistant to treatment, and median survival of patients is only about 15 months. In a study published in Neuro-Oncology, researchers at Mayo Clinic identify an important association between the naturally occurring enzyme Kallikrein 6, also known as KLK6, and the malignant tumors.

Early life exposure to gut microbes protects against autoimmune disease

Early life exposure to normal bacteria of the GI tract (gut microbes) protects against autoimmune disease in mice, according to research published on-line in the January 17 edition of Science. The study may also have uncovered reasons why females are at greater risk of autoimmune diseases such as multiple sclerosis, rheumatoid arthritis, and lupus compared to males.

Scientists identify new mechanism for schistosomiasis-bladder cancer connection

About 200 million people across 75 of the poorest countries in the world are now infected by the blood parasite Schistosoma haematobium (S. haematobium). The infection causes severe urogenital disease, but also causes bladder cancer in a number of patients and why this occurs is not clear.

U-M researchers to develop disorders of sex development decision-making tools for parents

When a child is born with a disorder of sex development, decisions regarding gender assignment and genital surgery are often made quickly and under pressure.

Aggressive breast cancer’s metastasis molecular switch identified

Scientists at Weill Cornell Medical College have discovered the molecular switch that allows aggressive triple negative breast cancer cells to grow the amoeba-like protrusions they need to crawl away from a primary tumor and metastasize throughout the body. Their findings, published in Cancer Cell, suggest a novel approach for developing agents to treat cancer once it has spread.

Mirena coil intrauterine device a better treatment for heavy menstrual periods

The hormone-releasing Mirena coil intrauterine device (IUD) is a better treatment for heavy menstrual periods than other conventional medical approaches, according to results of a major clinical trial led by scientists from the Universities of Nottingham and Birmingham.

New information on insulin and cell bonding mechanics

The discovery of insulin nearly a century ago changed diabetes from a death sentence to a chronic disease. Today a team that includes researchers from Case Western Reserve University School of Medicine announced a discovery that could lead to dramatic improvements in the lives of people managing diabetes.

Leptin hormone also regulates airway diameter

A new study led by Columbia University Medical Center (CUMC) researchers has found that leptin, a hormone that plays a key role in energy metabolism, fertility, and bone mass, also regulates airway diameter.

Body's sodium levels fluctuate rhythmically with 7-day and monthly cycles

Clinical pharmacologist Jens Titze, M.D., knew he had a one-of-a-kind scientific opportunity: the Russians were going to simulate a flight to Mars, and he was invited to study the participating cosmonauts.

Study finds a new way in which calcium signaling may be controlled

In a study published in Current Biology, scientists from the University of Rochester Medical Center, Marquette University and Oberlin College discovered a new way in which calcium signaling may be controlled. Study authors say their findings define a mechanism for regulating calcium signaling that has never been recognized before and should be of great help to the thousands of scientists who study the extremely important role of calcium signaling in health and disease.

Diabetes drug metformin works in different way than previously understood: Researchers

A team, led by senior author Morris J. Birnbaum, MD, PhD, the Willard and Rhoda Ware Professor of Medicine, with the Institute for Diabetes, Obesity, and Metabolism, Perelman School of Medicine, University of Pennsylvania, found that the diabetes drug metformin works in a different way than previously understood.

TRIP-Br2 plays a major role in energy metabolism and fat storage

As part of their ongoing research on the physiologic factors that contribute to the development of obesity, Joslin Diabetes Center scientists have identified a cell cycle transcriptional co-regulator - TRIP-Br2 - that plays a major role in energy metabolism and fat storage.
