Research Object Crate for Use Case 13: Novel Cell Surface Targets for Individual Cancer Patients Analyzed with Common Fund Datasets

A file was first uploaded. The file was parsed as a gene count matrix. Significantly over-expressed genes when compared to tissue expression in GTEx[1] were identified. RNA-seq-like LINCS L1000 Signatures[3] which mimick or reverse the the expression of IMP3 were visualized. Drugs which down-regulate the expression of IMP3 were identified from the RNA-seq-like LINCS L1000 Chemical Perturbagens[3]. Genes which down-regulate the expression of IMP3 were identified from the RNA-seq-like LINCS L1000 CRISPR Knockouts[3]. Genes were filtered by IDG Understudied Proteins[8]. The gene was searched with the MetGENE tool providing pathways, reactions, metabolites, and studies from the Metabolomics Workbench[9]. IMP3 was then searched in the Metabolomics Workbench[11] to identify associated metabolites. IMP3 was then searched in the Metabolomics Workbench[11] to identify relevant reactions. A list of regulatory elements in the vicinity of the gene were retrieved from the CFDE Linked Data Hub[14]. The GlyGen database[18] was searched to identify a relevant set of protein products that originate from IMP3. 1. Lonsdale, J. et al. The Genotype-Tissue Expression (GTEx) project.
