Abstract:
PURPOSE: A method for screening a material which enhances a skin barrier function is provided to effectively screening the material, and to diagnose diseases related to the skin barrier function. CONSTITUTION: A method for screening a material which enhances a skin barrier function comprises a step of determining a material which suppresses the expression of PDZK1 genes as the material which enhances the skin barrier function by screening the material which suppresses the expression of the PDZK1 genes. The method comprises a step of treating a nucleic acid molecule of PDZK1 with a candidate material, and a step of detecting expression change. The treatment with the candidate material comprises a step of treating a skin cell which is transformed with a vector containing the nucleic acid molecule with the candidate material. The skin cell is keratinocyte. The vector is adenovirus. A composition for enhancing the skin barrier function contains the material which suppresses the expression of the PDZK1 genes as an active ingredient.

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 method for evaluating the efficiency of a sun screen is provided to accurately evaluate efficiency of blocking blue/violet light. CONSTITUTION: A method for evaluating the efficiency of a sun screen comprises: a step of applying a subject on a sunlight permeable material; a step of irradiating skin cells with the sunlight; and a step of collecting the skin cells and measuring gene expression level in the cells. The sunlight is UV ray with 290-400 nm of wavelength or blue/violet light with 400-500 nm of wavelength. The sunlight permeable material is a quartz plate or band pass filter. The skin cells include keratinocytes, fibroblast, or melanocytes.
