| Research Abstract |
In order to find out the effect of adiponectin on lung cancer and lung disease, we made elastase inhalation model, VEGF receptor blocker model, and LPS administration model. However obvious inhivitive effects were not observed. In the subcutaneous lung cancer cell injection model, the regular diet group of Tg mice showed increase tumor size and weight. Because the size of adipocytes were small and mRNA expressions of p21 and p16 and protein expressions of p21 and p53 were suppressed in adipose tissue of Tg mice, we presume the tissues of Tg mice are kept homeostasis in "young", which might induce cancer growth in adipose tissue.
