Abstract:	Physiological and premature ageing are characterized by multiple defects in chromatin structure and accumulation of persistent DNA damage. Here we identify the NURD chromatin remodelling complex as a key modulator of these ageing-associated chromatin defects. We demonstrate loss of several NURD components during premature and normal ageing and we find an ageing-associated reduction in HDAC1 activity. Silencing of individual NURD subunits recapitulated chromatin defects associated with ageing and we provide evidence that structural chromatin defects precede DNA damage accumulation. These results outline a molecular mechanism for chromatin defects during ageing.
