  • Publication number: 20230226079
    Abstract: This invention relates to a novel method of treating solid tumors of the head and neck. More specifically, the invention relates to the use of Momordicine-I (M-I), an extract of bitter melon (Momordica charantia), to treat solid tumors, particularly those of the head and neck as well as the breast. Methods and compositions are disclosed related to administrating Momordicine-I with lipophilic solvents to subjects in need.

  • Publication number: 20090148832
    Abstract: The present invention provides a cell line capable producing infectious hepatitis C virus 1a (HCV 1a) particles in culture. Disclosed are compositions and methods for an HCV 1a (clone H77) transfected immortal human hepatocyte (IHH) capable of generating infectious HCV 1a virus particles in culture. Also disclosed are methods of using the cell line, or HCV 1a virus particles derived from said cell line, to screen for potential therapeutic agents which interfere with HCV 1a virus propagation to treat hepatic disease.

  • Patent number: 7232893
    Abstract: The present invention provides compositions and methods for selectively inhibiting the proliferation of stellate cells, which are important for the development of liver fibrosis upon liver injury. The invention describes conditioned media from immortalized hepatocytes as containing a death factor that induces apoptosis of activated liver stellate cells. This pro-apoptotic activity is shown to be associated with an 80 kDa protein, which is associated with a fetuin peptide sequence and an albumin peptide sequence.

  • Publication number: 20060275838
    Abstract: The present invention provides compositions and methods for selectively inhibiting the proliferation of stellate cells, which are important for the development of liver fibrosis upon liver injury. The invention describes conditioned media from immortalized hepatocytes as containing a death factor that induces apoptosis of activated liver stellate cells. This pro-apoptotic activity is shown to be associated with the peptide sequence of the actin depolymerizing molecule gelsolin and or fragments thereof. The apoptotic activity is increased upon incubation of immunoglobulins with the stellate death factor.
