Selective estrogen signaling key to postmenopausal risk of obesity

Summary:
Although the hormone estradiol-17-beta is a key reproductive hormone, it also contributes to the regulation of energy balance and body weight. As a result, estrogen deficiency following menopause is associated with an increased probability of obesity. New research has generated data that suggest it might be possible to develop drugs that selectively reduce the risks of obesity and metabolic disturbances in postmenopausal women.

The hormone estradiol-17-beta is a key reproductive hormone. However, it also contributes to the regulation of energy balance and body weight. As a result, estrogen deficiency following menopause is associated with an increased probability of obesity and increased risk for developing type 2 diabetes.

A team of researchers, led by Jon Levine, at Northwestern University, Evanston, has now generated new insight into the mechanisms by which ER-alpha signaling maintains normal energy balance. Specifically, the team found that nonclassical ER-alpha signaling is key to the effects of estradiol-17-beta on energy balance.

These data lead them to suggest that it might be possible to develop drugs that selectively activate nonclassical ER-alpha signaling to reduce the risks of obesity and metabolic disturbances in postmenopausal women.

The research appears in the Journal of Clinical Investigation.

Gilead's $1000-a-Pill Drug Could Cure Hep C in HIV-Positive People

Gilead's $1000-a-Pill Drug Could Cure Hep C in HIV-Positive People

TheStreet (July 21, 2014) — New research shows Gilead Science's drug Sovaldi helps in curing hepatitis C in those who suffer from HIV. In a medical study, the combination of Gilead's Hep C drug with anti-viral drug Ribavirin cured 76% of HIV-positive patients suffering from the most common hepatitis C strain. Hepatitis C and related complications have been a top cause of death in HIV-positive patients. Typical medication used to treat the disease, including interferon proteins, tended to react badly with HIV drugs. However, Sovaldi's %1,000-a-pill price tag could limit the number of patients able to access the treatment. TheStreet's Keris Lahiff reports from New York. Video provided by TheStreet
