Abstract:
A polydiacetylene sensor chip comprising protein is provided to detect rapidly protein-protein or protein-cell reaction without labeling of the subject to be analyzed, and reduce the amount of polydiacetylene and subject to be analyzed. A polydiacetylene sensor chip comprises a substrate, a vesicle bound to the substrate and having polymerized diacetylene represented by the formula(1): A-(L1)d-(CH2)e-C=C-C=C-(CH2)f-(L2)g-B, and a probe protein bound to the vesicle, wherein a sum d and g is 0, 1 or 2; a sum of e and f is an integer from 2 to 50; e and f are each independently an integer of 1 or more; A and B are each independently methyl group, amine group, carboxyl group, hydroxyl group, maleimide group, biotin group, hydroxysuccinimide group, benzoic acid group or ester group; and L1 and L2 are each independently alkyl group having carbon number of 2 or more, at least one ethylene oxide group, amine group, amide group, ester group or carbonyl group.
Abstract:
PURPOSE: A composition containing miRNA molecule or mimic of DUOX2 for controlling skin cell differentiation is provided to regulate DUOX2, filagrin, loricrin, keratin 1, and keratin 10 genes. CONSTITUTION: A composition for controlling skin cell differentiation contains miRNA molecule or mimic of DUOX2 having 7-25 bases with a base sequence of sequence number 1. The miRNA molecule or mimic targets 1358th to 1364th nucleic acids of DUOX2 mRNA 3'-UTR. The composition promotes skin cell differentiation. A miRNA inhibitor of DUOX2 targets 1358th to 1364th nucleic acids of DUOX2 mRNA 3'-UTR. The composition suppresses skin cell differentiation. The skin cell is keratinocytes.
Abstract:
PURPOSE: A composition for suppressing differentiation and growth of adipocytes is provided to treat or prevent circulatory system disease or ischemic heart disease. CONSTITUTION: A composition for suppressing differentiation or growth of adipocytes contains 0.00001 to 15 weight% of chemerin. The adipocyte is human bone marrow mesenchymal stem cell. A pharmaceutical composition is used in the form of oral administration formulation or injection. The oral administration formulation is formulated in capsule, tablet, suspension, syrup or powder. A functional health food composition for preventing or treating diabetes, hyperlipidemia, hypercholesterolemia, circulatory system diseases contains 0.00001-10 weight% of chemerin. The health food is used in the form of caramel, chocolate, diet bar or snack. A cosmetic composition for treating obesity contains 0.00001-10 weight% of chemerin as an active ingredient. The cosmetic composition is used in the form of massage cream, body lotion, body cream, body oil, or body essence.
Abstract:
PURPOSE: A method and a kit for screening a material which promotes skin cell differentiation is provided to quickly and simply screen the material. CONSTITUTION: A method for screening a material which promotes skin cell differentiation comprises: a step of treating a test material to skin cells; a step of identifying relative expression level of DUOX1(dual oxidase 1) gene(Genebank Accession No.: NM_017434) in the skin cells; and a step of determining a material which enhances the expression level is the material which promotes skin cell differentiation. The skin cells are keratinocytes. A composition for skin moisturizing, skin barrier function strengthening, or atopic dermatitis relief contains the material as an active ingredient.
Abstract:
PURPOSE: A composition containing octyl salicylate or phenylbenaimidazole sulfonic acid is provided to effectively block UVC and UVB. CONSTITUTION: A composition for blocking UVC contains one or more selected from the group consisting of octyl salicylate or phenylbenzimidazole sulfonic acid as an active ingredient. The composition is used in the form of solution, suspension, emulsion, paste, gel, cream, lotion, powder, soap, surfactant-containing cleansing, oil, foundation, oil-in-water, or water-in-oil. The maximum absorbance is in the wavelength of 200-290 nm.
