High-throughput, micro-droplet based screening platform for the evaluation of G-quadruplex binders

DNA is a major target of anti-cancer drugs. However, efforts have been made to increase the selectivity. Consequently, non-canonical sequences with unique structures are a major focus of research. Guanine-rich sequences self-assemble into G-quadruplex structures which are likely to play an indispensable role in various cellular processes like telomere maintenance, genomic stability and regulation of DNA replication and transcription. A considerable proportion of potential quadruplex sequences is located in the promoter regions of genes that play an important role in cell signalling. G-rich repetitive sequences were also identified in the telomeric region. Several compounds including metal complexes have been identified to be good G-quadruplex binders. Their medicinal significance led to the need for a rapid and efficient screening method to identify the best potential binders for a physiologically relevant G-quadruplex DNA/RNA.

My project aims at developing a high throughput, real-time micro-droplet based platform for the evaluation of quadruplex binders exploiting microfluidics technology. The idea is to perform FRET melting assays with optically labelled quadruplex sequences in micro-droplets. We also envisage to gauge the cytotoxicity of quadruplex binders against a number of different cell lines in a similar platform.
