Abstract:
PURPOSE: A composition containing miRNA for controlling pigmentation gene expression is provided to suppress tyrosinase, tyrosinase-related proteins, and melan-A expression. CONSTITUTION: A composition for controlling pigmentation gene expression contains miRNA containing a base of sequence number 1 as an active ingredient. The miRNA has continuous 27 bases containing ccuucuu of sequence number 1 and a base which suppresses pigmentation gene expression. The pigmentation gene is tyrosinase, tyrosinase-related protein 1, or melan-A gene. The miRNA targets 909-915th nucleic acids of melan A mRNA 3'-UTR. The composition is a cosmetic or pharmaceutical composition for skin whitening. A composition for controlling pigmentation gene expression contains a complementary base with miRNA of sequence number 1.

Abstract:
PURPOSE: A composition containing an oligonucleotide or mimic acting as an inhibitor of miRNA-526b is provided to control collagen generation and to prevent or treat aging. CONSTITUTION: A composition for controlling collagen contains 15-23 serial nucleotides of sequence number 1. The collagen is controlled by regulating the expression of matrix metalloproteinase 1(MMP1). The oligonucleotide reduces or suppresses the expression of MMP1 by hybridization with MMP1 mRNA. The composition is used for anti-aging.

Abstract:
A transgenic mouse is provided to show obese-inhibiting characteristic by over-express an isocitrate dehydrogenase 3 alpha(IDH3A), there by being used as a model animal for treating and studying obesity. An expression vector pcDNA-IDH3A comprises: a CMV promoter; an IDH3A gene; and a polyadenylated sequence. A method for preparing a transgenic Mus musculus comprises the steps of: (a) preparing the expression vector pcDNA-IDH3A; and (b) micro-injecting the expression vector into a pronucleus of a Mus musculus fertilized egg. Further, the IDH3A gene is cDNA synthesized from mRNA derived form human heart.
