Researchers at the University of Colorado School of Medicine have created a new and exciting mouse model to study how lipid sensing and metabolism in the brain relate to the regulation of energy balance and body weight. The research team, led by Hong Wang, PhD, created mice with a deficiency of lipoprotein lipase (LPL) in neurons, and observed two important reactions. First, the mouse models ate less and second, they became sedentary. Because LPL is important to the delivery of fatty acids to...

UT Southwestern Medical Center researchers have pinpointed a tiny site in the brain where the hormone leptin may help trigger the onset of puberty. The findings in mice indicate that a site within the hypothalamus called the ventral premammillary nucleus, or PMV, is the target where the hormone leptin effectively kick starts puberty in females. Researchers have known that puberty starts when individuals have enough energy stores or fat to meet the demands of reproduction, and that leptin...

The timing of the onset of puberty is linked to levels of nutrition: later onset is associated with malnutrition, while earlier onset is linked to childhood obesity. A team of researchers, led by Carol Elias, at the University of Texas Southwestern Medical Center, Dallas, has now generated data in mice that run counter to current thinking about the molecular pathway by which nutrition status affects the onset of puberty. Further, the team defines a new regulatory pathway for the process,...

New findings by researchers at UT Southwestern Medical Center suggest that serotonin "“ a brain chemical known to help regulate emotion, mood and sleep "“ might also have anti-diabetic properties. The findings, appearing online this week in Nature Neuroscience, also offer a potential explanation for why individuals prescribed certain kinds of anti-psychotic drugs that affect serotonin signaling sometimes have problems with their metabolism, including weight gain and the...

Research conducted by scientists at LSU Health Sciences Center New Orleans has found that two proteins in the brain act as valves to turn the hormone that regulates water retention in the body on and off. Their findings may lead to advances in treatment for diseases like high blood pressure, congestive heart failure, and cirrhosis of the liver. The research is published in the November 1, 2010 issue of Endocrinology. Daniel Kapusta, PhD, Professor of Pharmacology at LSU Health Sciences Center...

(Ivanhoe Newswire) -- Here's a new reason to hit the gym. Besides burning calories, it also makes you think you're fuller. New research shows exercise restores the sensitivity of neurons involved in the control of satiety or feeling full, which in turn contributes to reduced food intake and consequently weight loss. Obesity has been an increasing problem in the world. Just in the U.S, in 2009, only Colorado and the District of Columbia had a prevalence of obesity less than 20 percent....

There is now another good reason to exercise. Besides burning calories, exercise restores the sensitivity of neurons involved in the control of satiety (feeling full), which in turn contributes to reduced food intake and consequently weight loss. This is the conclusion of a study led by Brazilian researchers at the University of Campinas, and the findings will be published next week in the online, open access journal PLoS Biology. This disclosure may bring hope to over 40% of the population...

Researchers watched two groups of mice, both nearing the end of a two-day fast. One group was quietly huddled together, but the other group was active and alert. The difference? The second set of mice had been engineered so their brains produced more SIRT1, a protein known to play a role in aging and longevity. "This result surprised us," says the study's senior author Shin-ichiro Imai, MD, PhD, an expert in aging research at Washington University School of Medicine in St. Louis. "It...

A nutrient that's common to all living things can make hibernating marmots hungry - a breakthrough that could help scientists understand human obesity and eating disorders, according to a new study by a Colorado State University biologist. The study appears in the current issue of the Journal of Experimental Biology. Professor Greg Florant discovered he could slowly release a molecule called AICAR into yellow-bellied marmots that activates a neurological pathway driving food intake and...

An in vivo study shows for the first time that there is a stress-response system within the cochlea that mirrors the signaling pathways of the body's fight or flight response. Researchers have identified a hormone-like signaling system of the inner ear that sets baseline hearing sensitivity and helps protect against noise-induced hearing loss. "Our research shows, for the first time, that the cochlea's protective mechanism is likely to be largely a locally-produced phenomenon. The current...

The hypothalamus is an organ that serves as an important link, along the hypothalamic-hypophyseal axis, between the nervous system and the endocrine system. It is located within the cranial cavity, in the cerebrum, right below the thalamus. It also forms the floor of the third ventricle in the brain. It contains neural pathways, blood vessels, glial cells, and secretory cells—all of which work together to control things like body temperature, hunger, thirst, sleep, and hormonal and...
