Cancer cell-specific gene expression system

摘要

The present invention relates to a cancer-specific gene expression system, more particularly to a cancer-specific gene expression system characterized comprising a promoter with a binding site (E2Fbs) for E2F transcription factor expressed only in a cancerous cell and a structural gene. Said gene expression system thus can provide an effective way in conjunction with various combined structural genes to treat cancer by using the special feature of said system that specifically works on cancerous cells without affecting any normal cells.
