Abstract:
:The application of molecular and genetic techniques to the study of body weight regulation have produced exciting new insights into the physiological systems governing energy expenditure, appetite, and metabolic signaling. A number of new peptides have been identified that play important roles in these regulatory systems. These include the hormone leptin, the short and long forms of the leptin receptor, uncoupling proteins, agouti protein, melanocortin receptor isoforms, melanin-concentrating hormone, and the proteins responsible for tub and fat, two monogenic mouse models of obesity. This article reviews some of the new insights gained from studies of these peptides. Although much of this new knowledge has come from studies of obesity, there may be implications for the clinical syndromes associated with weight loss. As more is learned about these systems, potential new targets for therapeutic intervention will likely become evident. These interventions may develop first as obesity treatments, but investigators and clinicians involved in the care of cachectic patients should follow these scientific developments as well.
