Publication number: 20100058488Abstract: The present inventors discovered that knockout mice whose S1-5 gene function is lost develop age-related diseases or symptoms. In such knockout mice, bone mineral content, bone mineral density, and bone strength were found to be decreased, and the number of osteoclasts in bone tissues was found to be increased. Analysis of osteoclast-forming ability using bone marrow cells derived from the knockout mice revealed that osteoclast-forming ability is enhanced and osteoclasts are larger in the knockout mice than in wildtype mice. When purified S1-5 protein was added to this in vitro system, osteoclast-forming ability was inhibited. Furthermore, administration of purified S1-5 protein to osteoporotic model mice showed that this protein has the effect of improving osteoporosis. The above findings demonstrate that S1-5 protein is useful for treating and preventing age-related diseases such as osteoporosis.Type: ApplicationFiled: December 28, 2005Publication date: March 4, 2010Applicant: LOCOMOGENE, INC.Inventors: Toshihiro Nakajima, Naoko Yagishita, Tetsuya Amano

Publication number: 20080305102Abstract: Inhibition of synoviolin function was found to activate the cancer-suppressing protein p53. Substances inhibiting the function of synoviolin are useful as cancer therapeutic agents. The inhibition of synoviolin function was also found to lead to the inhibition of p53 ubiquitination, increased activity of p53 phosphorylation proteins, and the like. Based on these findings, the present invention provides methods capable of efficiently screening for cancer therapeutic agents. Further, it was also found that regulation of the autoubiquitination of synoviolin protein suppresses the proliferation of rheumatoid arthritis synovial cells. Substances regulating the autoubiquitination of synoviolin protein are useful as anti-rheumatic agents. Moreover, the present invention provides methods of efficiently screening for anti-rheumatic agents.Type: ApplicationFiled: June 23, 2006Publication date: December 11, 2008Inventors: Toshihiro Nakajima, Yukihiro Kato, Tadayuki Yamadera, Tetsuya Amano
