“…There is slightly more diversity of approaches in this space as compared to drugs partially due to the use multiomic data which allow constructing graphs with heterogeneous node attributes. The multiomics can be utilized to encode gene relationships and attributes using one or more data modalities, including correlations between genes ( 109 , 111 , 115 , 116 ), known protein interactions (i.e., PPI) ( 109 , 111 , 117 , 118 ) using STRING database ( 119 ), and relationships based on known gene pathways ( 109 ) using GSEA dataset ( 120 ). Recently, novel approaches have been explored such as heterogeneous graphs where both cell lines and drugs are encoded as graph nodes ( 108 , 116 , 118 , 121 ), and a model that utilizes diverse data types for building graphs, including differential gene expressions, disease-gene association scores and kinase inhibitor profiling ( 111 ).…”
