Abstract
- Epigenome contains a lot of information about cell state. Epigenetic analysis includes primarily sequence-based methods, which provide detailed data on distribution of modifications along the genome, but are poorly applicable for screenings. Specific fluorescence labeling and imaging of epigenetic modifications is an attractive complementary approach. It is currently based mainly on histone modifications study. We expect that inclusion of DNA modifications into imaging-based study would empower the method. In this review we discuss methods for fluorescence imaging of DNA modifications (mainly 5-methylcytosine). It opens an easy way to single cell analysis and high-throughput screening. Moreover, tracking epigenome changes in live cells becomes possible with genetically encoded probes. • Genomic DNA modification profile reflects a state of the cell. • Specific probes enable fluorescence imaging of DNA methylation. • Genetically encoded probes can be used to track epigenome changes in live cells.
