The chromatin-modifying protein SIRT6 has previously been shown to have anti-aging properties. Sundaresan et al. now show that SIRT6 expression is low in failing human hearts and SIRT6 in mice protects the heart by suppressing the activity of the c-Jun transcription factor, which acts as a global regulator of genes encoding components of the IGF-Akt signaling pathway.
