Abstract:
The present invention relates to a method and a kit for predicting chloasma. More specifically, in order to diagnose possibility of forming the chloasma by checking expression amount of genes which are differently expressed between chloasma tissues and normal skin tissues, a method and a kit for predicting chloasma comprise: one or more polynucleotides or complementary polynucleotides as probes which hybridize with polynucleotides of the sequence of the genes; a pair of polynucleotide primers of the sequence of the genes; or one or more monoclonal antibodies having amino acid sequences coded by the genes as a variable region. According to the present invention, the possibility of forming the chloasma on skin can be sensitively and rapidly diagnosed by using 23 kinds of highly expressed genes and 5 kinds of down regulated genes, which are specific to chloasma lesion area, as chloasma marker genes. [Reference numerals] (AA) Relative mRNA expression amount in melasma regions compare to normal region; (BB) Normal region
Abstract:
The present invention relates to a composition for skin whitening comprising ARP101. The composition for skin whitening, as one aspect of the present invention, reduces the amount of melanin by reducing the expression of melanogenesis-related proteins, thereby having whitening effects without cytotoxicity.
Abstract:
The present invention relates to a method for predicting chloasma formation and a diagnostic kit for chloasma formation and, more specifically, to a method for predicting chloasma formation and a diagnostic kit for chloasma formation, capable of diagnosing the possibility of chloasma formation on the skin by confirming the expression levels of genes which are differently expressed between the chloasma tissue and the normal skin tissue, wherein the diagnostic kit comprises: at least one polynucleotide sequence or its complementary polynucleotide as a probe hybridizing with polynucleotide of the gene sequence; a primer pair of the polynucleotide of the gene sequence; or at least one monoclonal antibody having, as a variable region, an amino acid sequence coded by the gene. According to the present invention, 23 high-expression genes and five low-expression genes, which are specific to a chloasma lesion, are used as a chloasma marker gene, thereby precisely and promptly diagnosing the possibility of chloasma formation on the skin. [Reference numerals] (AA) Relative mRNA expression level of a chloasma region as compared with a normal region; (BBC) Normal region

Abstract:
A method for inhibiting melanosome migration by using prohibitin siRNA(small interference RNA) is provided to inhibit expression of prohibitin in a melanin synthesis cell and uniformed distribution of melanosome in the melanin synthesis cell, so that the skin is whitened. The melanosome migration to the end of melanin synthesis cell is inhibited by administering prohibitin siRNA into the melanin synthesis cell, melan-a, thereby inhibiting binding of prohibitin to melanophilin as a melanosome vehicle and uniformed distribution of melanosome in the melanin synthesis cell.
