37 kDa LRP::FLAG enhances telomerase activity and reduces ageing markers in vivo.

ABSTRACT: Ageing is a degenerative process characterised by a decline in physiological functioning of the organism. One of the core regulators of cellular ageing are telomeres, repetitive DNA sequences of TTAGGG that cap the ends of chromosomes and are maintained by the ribonucleoprotein complex, telomerase. Age-dependent progressive loss of the telomere ends eventually induces cell cycle arrest for the induction of either replicative senescence or apoptosis. It was previously established that overexpression of the 37 kDa/ 67 kDa laminin receptor (LRP/LR) increased telomerase activity and telomere length while concomitantly reducing senescence markers in aged normal cells in vitro. Therefore, it was hypothesized that elevating LRP/LR in vivo may increase telomerase activity and hinder the ageing pro
