  • Patent number: 11957706
    Abstract: The present disclosure relates to a composition for preventing or treating fibrosis including an inhibitor of cyclin-dependent kinase 17 (CDK17) expression or activity. According to the present disclosure, the inhibitor of CDK17 expression or activity significantly reduces collagen production and cell activity and viability in activated hepatic stellate cells (liver fibrosis cell model), renal tubular epithelial cells (renal fibrosis cell model) in which fibrosis is induced by TGF-? treatment, and alveolar epithelial cells (lung fibrosis cell model) in which fibrosis is induced by TGF-? treatment, indicating that the composition of the present disclosure has an excellent effect in preventing or treating fibrosis.

  • Patent number: 10533992
    Abstract: Unlike a conventional method for evaluating a degree of ultraviolet protection through visual evaluation, the disclosed method for measuring a sunlight protection function can accurately and objectively measure and determine a degree of sunlight protection by measuring a change due to a material to be measured with respect to an expression amount of skin tissue antimicrobial peptides (AMPs) in skin cells, which decrease from exposure to sunlight, and/or a generation amount of S-nitrosylated protein. Additionally, the disclosed measurement method can determine whether blue/violet light of wavelengths of 400-500 nm, which induces the most skin damage among visible rays, is blocked and provide a more specified sunlight protection effect evaluation result. Moreover, by using the disclosed measurement method, a degree of sunlight protection can be indexed, and a sunlight protection composition for protecting normal skin from the blue/violet light can be provided.

  • Publication number: 20170181796
    Abstract: This specification provides a light source radiation apparatus for radiating light, a kit for lipolysis having a manual describing a method for dissolving fat by radiating light, and a slimming method for radiating light to skin. According to the specification, the present invention can dissolve neutral fat in a fat cell by radiating light of a wavelength in a range of light harmless to the body, thus can safely and effectively dissolve fat, and can be used for the slimming method by having the advantage of being more economical and convenient than a conventional lipolysis method.
