cIAP1/TRAF2 interplay promotes tumor growth through the activation of STAT3

The cellular inhibitor of apoptosis-1 (cIAP1) is a signalling regulator with oncogenic properties. The present work strengthens the importance of TRAF2 in the oncogenic properties of cIAP1. The TRAF2 interactome analysis showed that cIAP1 was critical for TRAF2 to bind to its protein partners. Thus, cIAP1 and TRAF2 would be essential subunits of a signalling complex promoting a pro-tumoral signal. cIAP1/TRAF2 promoted the activation of the canonical NF-κB and ERK1/2 signalling pathways. NF-κB-dependent production of IL-6 triggered the activation of the JAK/STAT3 axis in an autocrine manner. The authors demonstrate that cIAP1/TRAF2 binding is essential to promote tumour growth via activating the JAK/STAT3 signalling pathway.
