Abstract

Progression towards cellular senescence is associated with a marked accumulation of a senescent cell derived inhibitor of DNA replication called p21Sdi1. In the proposed project, transcriptional induction and protein stabilisation will be analysed as possible mechanisms to account for age-related increases in p21 protein levels. In particular, pathways affecting the proteosomal degradation of p21 in induction of cellular senescence. Finally, the impact of p21 on replication during cellular ageing in vitro will be studied, particularly focusing on pathway of Okazaki fragment processing, and examining possible involvement of the RecQ helicase implicated in the progeroid Werner's syndrome.
