  • Publication number: 20110212455
    Abstract: A method of screening a material for improving skin functions includes: (a) treating a skin cell with a candidate material; (b) detecting a change in a relative expression level of membrane-associated protein 17 (MAP17) gene; and (c) selecting a candidate material inducing the change in the expression level of the gene as a material for improving skin functions. That is to say, a material for improving skin functions is screened using MAP17 gene as a marker, on the basis of the change in the expression level of the MAP17 gene. A material for improving skin functions, which is useful in improving skin barrier function, promoting skin moisturization, preventing skin aging, or ameliorating skin troubles, may be effectively screened.

  • Publication number: 20100130348
    Abstract: Disclosed herein is an antireflective photocatalyst composition including a titanium dioxide-based photocatalyst, a binder, water, and alcohol, and a substrate using the composition. The antireflective photocatalyst composition is advantageous in that, when it is applied to a glass substrate, such as a glass antireflective film for a solar cell or a glass illuminator, it can prevent incident light energy from scattering and improve optical transmissivity, and in that it decomposes pollutants due to the dual action of harmful gas decomposition and self-purification, which are specific characteristics of a photocatalyst.

  • Publication number: 20060258609
    Abstract: The downregulation of PRP 19 (precursor RNA processing 19) protein expression results in effectively reducing the expression of SCD1 (stearyl CoA desaturase-1), the key lipogenic enzyme, and its down-stream triacylglycerol synthesis enzymes, DGAT-1 (diacyglycerol acyltransferase-1) and GPAT (glycerol-phosphate acyltransferase), as well as the intracellular content of neutral lipids, the major target for treating obesity.
