The targets of these molecules were related to cell proliferation (X-linked inhibitor of apoptosis protein, XIAP [40]; Protein Kinase A, PKA [41]), cell signaling (HRAS) [42], resistance to chemotherapy (heat shock protein 27, Hsp27) [43], or cancer stroma (TGFβ2) [44]. The gene discussed is XIAP; the disease is cancer.
