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. The gene discussed is CTAG1B; the disease is cancer.
