Cell-Seq – a unique tool to find new drug targets for unmet medical needs

Modifier genes — compensatory genes that counteract the effect of a disease-causing gene

Modifier genes explain why some people with genetic mutations linked to severe disease have only mild or no symptoms. Modifier genes therefore positively influence the severity of disease and act as a ‘natural form of protection’. To date, modifier genes or compensatory genes have been difficult to identify, especially for genetic disorders. Now, for the first time, Scenic is systemically exploring modifier genes using its proprietary platform technology for a large variety of disorders, including inherited diseases.

Our Cell-Seq™ platform enables high-resolution mapping of modifier genes for novel target discovery

Scenic Biotech has overcome the technical challenges of reliably finding modifier genes or the “hidden disease protection factors” using Cell-Seq, its unique discovery platform. Using functional genomics, Cell-Seq can create high-resolution disease maps that profile previously uncharted biological pathways and disease biology in an unprecedented fashion. This allows to uncover completely novel, potent drug targets that form the basis for Scenic’s rapidly growing pipeline of novel disease therapeutics. We also leverage the power of Cell-Seq and its associated data warehouse in collaborations with pharma partners.

Our platform, Cell-Seq, enables a comprehensive overview beyond modifier genes for many different disease phenotypes to select the best targets.

Cell-Seq uses special human cells that carry only a single copy of every gene (haploid), instead of the usual two (diploid) In addition to the primary disease-causing mutation, individual genes in billions of these haploid human cells are inactivated to create a very large library of mutant cells. This inactivation involves a process called gene-trap mutagenesis so that nearly every gene in the genome is inactivated/disabled, often several thousands of times.

The library of mutant cells is then stained using fluorescent labelling for a specific disease/pathway marker, such as a disease-associated process, to quantify how the gene mutation affects the cell’s health.

Cells with the cellular phenotype of interest are isolated using a FACS (fluorescent activated cell sorter) and the experimentally introduced mutations are determined using modern DNA sequencing technology.

Bioinformatics analysis then identifies every gene that modifies the cellular phenotype to enable high resolution “disease maps” to be generated so that the best disease modifiers can be viewed and then selected for target validation and drug development. Hundreds of these “maps” have been generated to date.

The Cell-Seq platform is used on healthy and diseased cells in parallel to unlock disease-specific modifier genes, including disease suppressors. In addition, our proprietary data-mining tools allow to map previously uncharted biological pathways and interrogate disease biology in an unprecedented fashion.

We are building the largest proprietary data warehouse of modifier genes.

We have identified novel modifier genes for over a dozen diseases and built a robust pipeline of first-in-class small molecule inhibitors based on these new drug targets. Discover our ongoing programs of discovery, development and collaborations!
