| Research Abstract |
Lipofection is the most versatile transfection methods to transfect genes into mammalian cells, because of its safety and its handiness. However, the expression efficiency of the transfected genes with this method is much lower than that with viral vector. We therefore attempted to develop highly efficient enhancer for lipofection. According to this objective, we accomplished the development of lipofection enhancers which enhance the expression of genes up to 23 times more than that of control. Structure of the enhancer is based on histone deacetylase(HDAC) inhibitors, which increase acetylation level of histone in nucleus resulting in the enhancement of transcription efficiencies. HDAC inhibitors also inhibit a cytosolic isozyme of HDAC_s, HDAC6, to facilitate transportation of transfected genes to the nucleus. This may also contribute to the enhancement of the transfected gene expression.
