AUTOPHAGY

Autophagy goes nuclear

Sirtuins are highly conserved enzymes with key roles in life extension in multiple organisms. A study now describes selective autophagic degradation of nuclear SIRT1 in senescent cells. These observations suggest that blocking sirtuin degradation could be a potential approach for anti-ageing therapies.
