Scientists have created a new tool called Corgi that can predict how DNA sequences work in different cell types. This could help us understand diseases and develop new treatments.
Deep learning approaches have changed the way scientists study DNA sequences. A team of researchers at the Max Planck Institute for Molecular Genetics has developed an AI tool called Corgi (Context-aware Regulatory Genomics Inference). Corgi can predict how the genome behaves in different cell types, which is important because each person's cells are unique due to small genetic variations.
These variations can affect gene expression in cells. Researchers want to understand these variations because they may be linked to diseases and could help with personalized medicine. However, it's hard to figure out which variations are important. AI-based tools have been developed to predict the effects of these variations from DNA sequence data. But these tools often have limitations.
Corgi is different because it considers the cellular context that determines how genes are turned on or off. This means it can correctly predict measurements related to genome activity, including gene expression and chromatin accessibility. The researchers created an architecture for Corgi that resembles real biological processes in cells by integrating data from regulatory genes.
An improved version of the tool, called Corgi+, can even infer epigenetic information from RNA sequencing data. This could help fill gaps in data sets without conducting every experiment directly. The scientists hope their approach will also improve virtual cell models, which are systems that mimic the effects of gene perturbations at a cellular level.
