Synthetic ligand promotes gene expression by affecting GC sequence in promoter.

ABSTRACT

A naphthyridine carbamate tetramer (NCT8) is a synthetic compound, which selectively binds to nucleic acids containing CGG/CGG sequence. Although NCT8 is a promising compound for a wide range of DNA and RNA based biotechnology such as modulation of specific gene expression, little is known about its behavior in human cells. In the present study, we investigated the changes induced in gene expression by NCT8. Genes differentially expressed in the presence of NCT8 in HeLa cells were identified by whole-transcriptome analysis. The whole-transcriptome analysis showed that NCT8 significantly induced up-regulation of specific genes, whose promoter region has GC-rich sequence.
