  • Publication number: 20100273708
    Abstract: The present invention provides adiponectin expression-inducing agents, and therapeutic agents using the same for obesity and obesity-related diseases such as cardiovascular diseases or metabolic diseases, as well as methods of searching for adiponectin expression-inducing agents. KLF9, which can bind to the 32-bp fragment of position ?188 to position ?157 from the adiponectin expression start site, was demonstrated to enhance adiponectin promoter activity. Therefore, the present invention uses KLF9 as an adiponectin expression-inducing agent, and suggests that KLF9 replenishment therapy is useful for preventing and/or treating obesity or obesity-related diseases including metabolic diseases such as insulin resistance and type II diabetes, and cardiovascular diseases.

  • Publication number: 20090239938
    Abstract: A scavenger receptor A expression down-regulator and a drug for preventing or treating arteriosclerosis which contain, as the active ingredient, a C-terminal globular domain of adiponectin, adiponectin, or a gene encoding the domain or adiponectin. According to the present invention, there is provided a preventive or therapeutic agent capable of directly preventing intimal thickening, which constitutes an essential feature of arteriosclerosis. This effect can be attained through arresting the onset and development of arteriosclerosis by reducing the expression level of scavenger receptor A in arterial walls and preventing lipid buildup in macrophages.

  • Patent number: 7523798
    Abstract: The duct comprises the upper member and the lower member, which are formed separately and assembled integrally by being attached to one another. There is provided the seal member to interconnect the opening at the lower member and the intercooler, which is pressed against the upper face of the intercooler. The front side of the lower member is supported at the shroud panel, and the rear side of the upper panel is supported at the cowl panel. Thus, the rear attachment portion is detached earlier than the front attachment portion at the pedestrian's hit. Accordingly, the duct can be split surely and the engine hood can be allowed to be properly deformed without being prevented, so that the protection of the head of pedestrians can be attained properly.

  • Publication number: 20070238649
    Abstract: The present inventors revealed by using fasted and refed mice, that AdipoR1/R2 is a regulator of metabolic sensitivity to nutritional conditions and insulin. They showed that mRNA level of AdipoR1/R2 increased by STZ treatment, and that this increase was restored by insulin. The present inventors confirmed in vitro that insulin reduces AdipoR1/R2 mRNAs in myocytes and such. It was also confirmed that in insulin-resistant models, the AdipoR1/R2 expression was downregulated, and that AMP kinase activation by adiponectin was decreased. The present inventors discovered by using insulin signaling pathway inhibitors, that the downregulation of adiponectin receptors by insulin was mediated by the PI3-kinase/Foxo1 pathway.

  • Publication number: 20070042424
    Abstract: We have discovered a “human adiponectin ELISA kit”, which can specifically measure adiponectin in human blood serum (or blood plasma) or in extracted fluid from lipocytes or culture supernatant fluid. After fractioning human serum by use of gel filtration column, each fraction was measured by the present kit, and as a result, adiponectin immunity activity was detected as a plurality of peaks at above 670 kD of molecular weight. From the results, it is presumed that adiponectin is present in the blood as a polymer or forms a complex with polymer proteins.
