| Research Abstract |
Although obesity is characterized as enlargement of adipose tissue, effect of hypoxic stress induced by obesity on the function of adipocyte is still unknown. Here, we revealed that hypoxic stress stimulated the production of angiogenic factors and inflammatory cytokines accompanied with acceleration of lipid accumulation. In addition, as a result of signaling pathway analysis, hypoxic stress evoked activation of akt pathway. Taken together, as hypoxic stress evokes variety of phenotype in adipocytes, elucidation of hypoxia responsive signaling pathways which are responsible for induction of angiogenesis, inflammation would be helpful for the discovery of novel target for the prevention of obesity related diseases.
