Here, we put forth a speculative model that posits a connection linking telomere damage and p53 activation with stem-cell and mitochondrial dysfunction. This model offers a unifying explanation of how telomeres influence the health of the ageing organism across diverse tissues with wide-ranging proliferative profiles.

The results presented here demonstrate that activation
of p53 inhibits mTOR activity and regulates its downstream
targets, including autophagy, a tumor suppression process. Moreover,
the mechanisms by which p53 regulates mTOR involves AMP
kinase activation and requires the tuberous sclerosis (TSC) 1TSC2
complex, both of which respond to energy deprivation in cells. In
addition, glucose starvation not only signals to shut down mTOR,
but also results in the transient phosphorylation of the p53 protein.
Thus, p53 and mTOR signaling machineries can cross-talk and
coordinately regulate cell growth, proliferation, and death.
