Abstract:
PURPOSE: A method for screening a gene which characteristically developing aging is provided to control gene expression and to suppress aging on the skin. CONSTITUTION: A method for screening a gene associated with skin aging comprises: a step of extracting total RNA from skin tissue and performing microarray; a step of analyzing genes which are changed by aging using bioinformatics; a step of selecting a candidate gene relating to skin aging; and a step of determining a candidate gene. The skin aging includes intrinsic aging or menopause aging.
Abstract:
PURPOSE: A composition for skin whitening containing a material which suppresses expression or activation of alpha-synuclein gene is provided to ensure skin whitening activity without citotoxicity. CONSTITUTION: A composition for skin whitening contains a material which suppresses expression or activation of alpha-synuclein gene. A pharmaceutical composition for skin whitening contains the composition. The alpha-synuclein gene encodes alpha-synuclein protein with an amino acid sequence of sequence number 1. The alpha-synuclein gene has a base sequence of sequence number 2. The material is an antibody or antibody fragment which specifically binds to the protein.
