  • Patent number: 9683040
    Abstract: The present invention relates to an antibody having an anti-angiogenesis activity. More specifically, the present invention relates to an antibody against ROBO4 and a pharmaceutical composition containing the antibody. An object of the present invention is to provide an anti-ROBO4 antibody having an anti-angiogenesis effect, a pharmaceutical composition or the like comprising the antibody, a method for suppressing angiogenesis using the antibody, etc. Another object of the present invention is to provide a method for producing the antibody. The antibody of the present invention activates the downstream signal of ROBO4 and has a suppressive activity against cell migration induced by VEGF or bFGF. The antibody of the present invention also exhibits an anti-angiogenesis effect in in-vivo models.

  • Publication number: 20060217299
    Abstract: It was discovered that hepatitis B virus x interacting protein (XIP) is cleaved and degraded by caspase-1, and the cleavage recognition site of XIP was also discovered. Based on these findings, the present invention provides a method and composition for inhibiting the degradation of XIP, more particularly, inhibiting the degradation of XIP caused by caspase-1, preventing and/or treating a disease attributable to the degradation of XIP, inhibiting the replication and/or transcription of hepatitis B virus, preventing and/or treating hepatitis B, and preventing and/or treating hepatic cancer caused by hepatitis B virus.
