Abstract:
Werner syndrome is a premature aging disease caused by the mutation in the WRN gene. The cloning and characterization of the WRN gene and its product allows investigators to study the disease and the human aging process at molecular level. This review summarizes the recent progresses on various aspects of the WRN research including functional analysis of the protein, interactive cloning, complexes formation, mouse models, and SNPs (single nucleotide polymorphisms). These in depth investigations have greatly advanced our understanding of the disease and elucidated future research direction for Werner syndrome and the human aging process.Keywords:

Werner syndrome (WS) is a rare autosomal recessive disorder in humans characterized by segmental premature aging. Somatic cells from WS individuals show low replicative capacity, hypersensitivity to DNA-damaging agents, increased genome instability, and altered telomere maintenance (1). The incidence of sarcomas is significantly higher in WS patients than in normal individuals (1). Genetic evidence indicates that WS is caused by loss of function mutations in the WRN gene, which encodes a protein that belongs to the RecQ family of DNA helicases. Polymorphisms in WRN have been demonstrated to be associated with breast cancer (2) and soft tissue sarcomas (3,4). The WRN gene has been cloned and the properties of WS cells and WRN protein have been studied extensively. Nevertheless, the pathophysiology of WS and the cellular and molecular mechanisms involved in WS pathogenesis remain poorly understood. Because WS is a progerioid disease, it is used as a model system to better understand the process of aging in humans.
