Patterns of increased adiposity and food intake in overweight children persist to adulthood, consistent with the idea that some metabolic set-points are established at a young age. The Zeltser lab is focused on characterizing two types of developmental processes that could, in principle, impart persistent influences on metabolic phenotypes: (1) maternal influences on the differentiation of key neuronal populations in the embryonic and neonatal hypothalamus, and (2) the establishment of defended set-points for phenotypes related to body weight and adiposity during the peri-pubertal period. Our research, a synthesis of molecular biology, developmental neuroscience, mouse genetic models, and metabolism, reflects a novel approach to studying the molecular physiology of childhood obesity. Recently, we have extended this type of approach to develop a novel mouse model of Anorexia Nervosa. By analyzing metabolic and physiological outcomes in conjunction with neuroendocrine and neuronal phenotypes, we hope to elucidate how the maternal, psychosocial and nutritional factors influence susceptibility to obesity/Eating Disorders. In the long term, we hope that our research leads to the development of more efficacious strategies to combat these disorders.
