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.

Interferon alpha revs immune cells but cancer cells ignore it

A new study shows that an important drug used in the treatment of malignant melanoma has little effect on the melanoma cells themselves. Instead, it activates immune-system cells to fight the disease.

Discovery suggests location of genes for breast density, a strong risk factor for breast cancer

Studying the DNA of 889 people, gene hunters at the Mayo Clinic and H. Lee Moffitt Cancer Centers have identified a region on chromosome 5p that is significantly associated with dense breast tissue, a known risk factor for breast cancer.

Neurotransmitter current not flowing through ion channels

In studying how neurotransmitters travel between cells -- by analysis of events in the dimensions of nanometers -- Cornell researchers have discovered that an electrical current thought to be present during that process does not, in fact, exist.

FDA approves Somatuline Depot to treat acromegaly

The U.S. Food and Drug Administration has approved Somatuline Depot (lanreotide acetate injection) for the treatment of acromegaly, a rare and potentially life threatening disease in adults caused by abnormal secretion of growth hormone (GH), commonly from a benign tumor located in the pituitary gland located in the brain.

Sildenafil increases release of key reproductive hormone oxytocin

Researchers at the University of Wisconsin-Madison report this month that sildenafil increases the amount of oxytocin released by stimulation of the posterior pituitary gland, a small structure directly underneath the brain that regulates hormone levels in response to neural signals.
