Comparative nutrition, companion animal nutrition, nutritional genomics, appetite regulation and obesity, intestinal microbiota and disease
The Swanson laboratory applies genomic biology to solve nutrition- or disease-related problems in the areas of 'appetite regulation and obesity' and 'intestinal health and disease'. Both comparative and applied nutrition research projects are performed in our laboratory, including those studying human subjects, traditional animal models (e.g., rodents, dogs or cats) and exotic animals (e.g., wild felid species).
A primary aim of our laboratory is to study the effects of diet, age and genotype on intestinal microbiota abundance and activity. DNA-based techniques such as denaturing gradient gel electrophoresis (DGGE) and quantitative polymerase chain reaction (qPCR) are currently being used in the lab. Current projects are designed to evaluate the effects of diet (e.g., high protein diets; prebiotic supplementation), age (e.g., weanling animals, geriatric vs. young adults) and genotype (e.g., numerous wild and domestic felid species) on intestinal microbial populations. Key associations between intestinal microbiota and disease are also being studied.
Another primary area of research pertains to appetite regulation and obesity. In addition to measuring gut peptide response to dietary manipulation, molecular techniques such as DNA microarrays and qRT-PCR are used to identify mechanisms or metabolic pathways affected in key metabolic tissues. Adipose tissue and skeletal muscle play important roles in energy homeostasis and glucose and lipid metabolism and are the focus of several ongoing projects.
