Oxidative stress and antioxidant response in fibroblasts from Werner and Atypical Werner Syndromes

Oxidative stress and antioxidant response in fibroblasts from Werner and Atypical Werner Syndromes

Werner Syndrome (WS, ICD-10 E34.8, ORPHA902) and Atypical Werner Syndrome (AWS, ICD-10 E34.8, ORPHA79474) are very rare inherited syndromes characterized by premature aging. While approximately 90% of WS individuals have any of a range of mutations in theWRN gene, there exists a clinical subgroup in which the mutation occurs in the LMNA/C gene in heterozygosity. Although both syndromes exhibit ...

DNA damage accumulation and TRF2 degradation in atypical Werner syndrome fibroblasts with LMNA mutations

Segmental progeroid syndromes are groups of disorders with multiple features suggestive of accelerated aging. One subset of adult-onset progeroid syndromes, referred to as atypical Werner syndrome, is caused by mutations in the LMNA gene, which encodes a class of nuclear intermediate filaments, lamin A/C. We previously described rapid telomere attrition and accelerated replicative senescence in...

Werner Syndrome

Werner Syndrome (WS) is an autosomal recessive disease that leads to the premature manifestation of clinical symptoms associated with normal aging. Clinical symptoms include: short stature, graying/loss of hair, osteoporosis, cataracts, atherosclerosis, type II diabetes, hypogonadism, skin ulcers, reduced fertility, and high incidence of malignant neoplasms. They appear in one’s 20’s and 30’s, ...

Werner Syndrome

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, comple...
