  • Patent number: 8697369
    Abstract: Using betaKlotho or a substance that increases or inhibits betaKlotho activity as an agent for controlling the activity of FGF21 mediated by an FGF receptor, the present invention provides a pharmaceutical composition comprising such betaKlotho or such substance as an active ingredient, particularly, a pharmaceutical composition for anti-metabolic syndrome, and further particularly, a pharmaceutical composition for therapeutic or preventive use associated with the control of blood glucose level. In addition, the present invention provides a screening system for each of a substance that enhances or suppresses betaKlotho activity, an FGF21-like active substance, and a betaKlotho-like active substance, which uses a cell system that has expressed an FGF receptor and/or betaKlotho on the surface thereof.

  • Patent number: 8304393
    Abstract: It is intended to provide a novel oligopeptide which can be relatively easily produced, has not only a hair growth-stimulating effect but also an effect of promoting the growth of epithelial cells (for example, skin regeneration) and can easily pass through the horny layer to thereby reach the desired target cells in which its effects are to be exerted. Namely, water-soluble oligopeptides containing a proryl isoleucyl glycyl unit or an isoleucyl glycyl serine unit and having from 3 to 7 amino acids and water-soluble salts thereof.

  • Publication number: 20120251455
    Abstract: A hair removing agent or a hair growth inhibiting agent is provided by determining an endogenous factor having a hair growth inhibitory activity, screening for substances having an activity similar to that of the endogenous factor or substances enhancing the activity or expression of the endogenous factor, and utilizing the physiological activities of such substances. It has been found that FGF18 inhibits hair growth. A method of screening for FGF18-like active substances, substances that promote the activity of FGF18 or substances that promote the expression of FGF18 to thereby obtain candidates for the hair growth inhibiting agent or hair removing agent is disclosed. Also disclosed is a hair growth inhibiting agent or a hair removing agent comprising, as an active ingredient, FGF18 and/or an FGF18 partial peptide, or an FGF18-like active substance and/or a substance that promotes the activity or expression of FGF18 (e.g., Digenea simplex extract).
