Tumour necrosis factor receptor-associated factor 6 (TRAF6) is a ubiquitin E3
ligase that regulates important biological processes. However, the role of TRAF6
in cardiac hypertrophy remains unknown. Here, we show that TRAF6 levels are
increased in human and murine hypertrophied hearts, which is regulated by
reactive oxygen species (ROS) production. Cardiac-specific Traf6 overexpression
exacerbates cardiac hypertrophy in response to pressure overload or angiotensin
II (Ang II) challenge, whereas Traf6 deficiency causes an alleviated hypertrophic
phenotype in mice. Mechanistically, we show that ROS, generated during
hypertrophic progression, triggers TRAF6 auto-ubiquitination that facilitates
recruitment of TAB2 and its binding to transforming growth factor beta-activated
kinase 1 (TAK1), which, in turn, enables the direct TRAF6-TAK1 interaction and
promotes TAK1 ubiquitination. The binding of TRAF6 to TAK1 and the induction of
TAK1 ubiquitination and activation are indispensable for TRAF6-regulated cardiac
remodelling. Taken together, we define TRAF6 as an essential molecular switch
leading to cardiac hypertrophy in a TAK1-dependent manner.
