Many disease pathogeneses are contributed by multiple factors, involving a complex set of genes and pathways. Therefore, we believe that drug combination remedies can bring a larger therapeutic impact on patients. However, the conventional approaches for drug combination screens are not only expensive but also time-consuming; still, they only allow the testing of a limited number of drug combinations. The CombiGEM-CRISPR platform couples the versatile combinatorial genetics en masse technology and the programmable CRISPR-Cas9 system, and this allows high-throughput screening of genetic combinations mimicking the effect brought by drug combinations (Wong et al., Nature Biotechnology 2015; Wong et al., PNAS 2016; Zhou et al., Cell Reports 2020). This platform can rapidly assemble multiplex barcoded combinatorial genetic libraries, where each combination can be tracked based on their barcodes via high-throughput sequencing. To do drug combination screens, we select the guide RNAs (gRNA) targeting the drug-targeting genes and assigned a unique barcode to each of the gRNAs, then we build a multiplex barcoded gRNA library and identify the combined gRNA knockouts that give us the desired phenotype by doing a Next-Generation Sequencing (NGS) of the barcodes. Using this approach, our lab has successfully found synergistic drug combinations using the CombiGEM-CRISPR platform on various types of cancers and neurodegenerative diseases and is interested in improving this platform and screening for combination remedies in other complex genetic diseases.
The PhD project provides intensive training in high-throughput molecular biology, CRISPR-based genome editing, and NGS-based library screening and data analysis techniques.
