PDCD1 and systemic lupus erythematosus: For example, one of the associations with shortest path between Tamoxifen and SLE is via a common biological process of apoptosis (GO_0006915) and T cell receptor signaling pathway (KEGG: hsa04660) that are traversed by two genes: PDCD1 (Gene_5133, programmed cell death 1) that is associated with SLE via property of "associates_with", and gene AKT1 (Gene_207, v-akt murine thymoma viral oncogene homolog 1) that is found to be associated with known indication of Tamoxifen (Figure 7a).
