Abstract

The tropical freshwater zebrafish has recently emerged as a valuable model
organism for the study of adipose tissue biology and obesity-related disease. The strengths of the zebrafish model system are its wealth of genetic mutants, transgenic tools and amenability to high-resolution imaging of cell dynamics within live animals. However, zebrafish adipose research is at a nascent stage and many gaps exist in our understanding of zebrafish adipose physiology and metabolism. By contrast, adipose research within other, closely-related, teleost species has a rich and extensive history, owing to the economic importance of these fish as a food source. Here we compare and contrast knowledge on PPARG-mediated adipogenesis derived from both biomedical and aquaculture literatures. We first concentrate on the biomedical literature to; (i) briefly review PPARG-mediated adipogenesis in mammals, before (ii) reviewing Pparg mediated adipogenesis in zebrafish. Finally, we (iii) mine the aquaculture literature to
compare and contrast Pparg-mediated adipogenesis in aquaculturally-relevant teleosts. Our goal is to highlight evolutionary similarities and differences in adipose biology that will inform our understanding of the role of adipose tissue in obesity and related disease.
