  • Publication number: 20110171661
    Abstract: Provided are a method of diagnosing the recurrence or possibility of recurrence of hepatocellular carcinoma after hepatocellular carcinoma surgery and a method of screening a drug for preventing the recurrence of hepatocellular carcinoma after hepatocellular carcinoma surgery and treating hepatocellular carcinoma. Specifically, the recurrence or possibility of recurrence of hepatocellular carcinoma after hepatocellular carcinoma surgery is diagnosed and a drug for preventing the recurrence of hepatocellular carcinoma after surgery and treating hepatocellular carcinoma is screened, by measuring expression levels of a metastatic tumor antigen 1 or metastasis associated 1 (MTA1) protein in a biological sample taken from a patient in which hepatocellular carcinoma recurs or is likely to recur after hepatocellular carcinoma surgery and comparing the measured expression levels of the MTA1 protein with those of a normal control group.

  • Publication number: 20110162092
    Abstract: The present invention relates to a composition comprised of AKAP12 (A-Kinase anchoring protein 12) and to uses of AKAP12 mutant zebrafish as an animal model. More particularly, the following characteristics are noted in the present AKAP12 mRNA knockdown zebrafish: crooked or shortened tail, inability to move normally, non-uniform micro-vasculature in the brain, and change in heart shape with non-uniform and weak heartbeats. It also has various circulatory and genetic defects, such as hemorrhage from the ventricles of the heart, brain, and retina. All of these defects can be cured with AKAP12 injection. Therefore, AKAP12 can be used as an active component for a composition to prevent and heal circulatory and genetic defects that are caused by AKAP12 deficiency, and as a hemorrhage inhibitor. Further, the AKAP12 deficient mutant zebrafish can be useful as an animal model for verification of effectiveness of treatment for genetic defects in the circulatory system.

  • Publication number: 20110123538
    Abstract: The present invention relates to a composition comprising a Ninjurin 1 expression or activity inhibitor for the prevention and treatment of inflammatory disease. Ninjurin 1 protein is specifically expressed in macrophages around blood vessels, increases cell-cell adhesion and cell-matrix adhesion, increases expressions of Wnt7b (Wingless-type MMTV integration site family, member 7B) and Ang2 (angiopoietin-2), but reduces expression of Ang1 to induce apoptosis of vascular endothelial cells. In addition, Ninjurin 1 protein is up-regulated when inflammation is induced and induces iNOS expression as well as increased NO generation. Therefore, the Ninjurin 1 protein expression or activation inhibitor can be effectively used as an active ingredient of a composition for the prevention and treatment of inflammatory disease.
