Mitochondria and senescence: new actors for an old play

Nicolás Herranz et al. EMBO J. .

Abstract

Mitochondrial dysfunction has been linked to both cellular senescence and ageing. Despite the relationship, it is still unclear whether mitochondria have a causal role in senescence. In this issue of The EMBO Journal, Correia-Melo et al (2016) combine targeted depletion of mitochondria with impairment of their biogenesis to demonstrate that decreased numbers of mitochondria impair the senescence response. Their results suggest that targeting mitochondria could reduce the detrimental effects of senescence during ageing.

Figure 1. Mitochondria are important effectors of the senescence response
Passos and colleagues (Correia‐Melo et al, 2016) describe that mitochondria form part of an autoregulatory loop involving the DNA damage response (DDR), mTOR and the production of ROS that results in persistent DDR and has a stabilizing effect on senescence.
