1. An isolated nucleic acid composition for inducing microRNA mir-434-associated gene silencing effects against tyrosinase, comprising:
- a SpRNAi-RGFP expression vector capable of expressing an intronic RNA molecule having a sequence which contains the sequence of SEQ.ID.NO;
8, wherein the intronic RNA molecule having the sequence of SEQ.ID.NO.8 targets tyrosinase gene.

Abstract
The present invention relates to a method and composition for generating a non-naturally occurring intron and its components capable of being processed into small hairpin RNA (shRNA) and/or microRNA (miRNA) molecules by skin cells and thus inducing specific gene silencing effects on skin pigment-related genes and/or aging-causing genes in the cells. The gene silencing effects so obtained are not only useful for lightening and whitening skin colors but also useful for suppressing unwanted aging gene activities in skins.
