In order to map ctag1b/a to cancer pathways and to discover co-expressed genes in its network neighborhood, we exploited its re-activation in synovial and myxoid liposarcomas but not in dedifferentiated liposarcomas or myofibrosarcomas and leiomysosarcomas (Figure 1) and mined its physical and genetic interactions. This evidence concerns the gene CTAG1B and myxoid liposarcoma.
