Description

Telomerase repairs/elongates the telomeres and is crucial in cellular proliferation. TERT expression is sufficient to overcome cellular senescence in culture [24], but overexpression of TERT in mice does not extend longevity [30]. Most human cell lines have low or insignificant levels of TERT while cancer cells often have high levels [102]. TERT expression in primary human fibroblasts results in a linear increase in DNA methylation age with cell population doubling number, indicating that TERT may also play a role in regulating the epigenetic clock [4504].

Cardiac-specific Tert activation after myocardial infarction in adult mice results in attenuated cardiac dilation, improved ventricular function, smaller infarct scars and increased mouse survival [3624]. Tert expression in a mouse model of pulmonary fibrosis improved lung function and lowered inflammation and fibrosis in addition to lowering DNA damage, apoptosis and senescence [4505]. In humans, mutations in TERT have been linked to aplastic anaemia [1465]. As such, TERT appears to be an important player in cellular proliferation, even if its relation to human ageing remains obscure.
