Aging: Progeria and the Lamin Connection
The relationship between progerias--diseases that resemble premature aging--and the normal aging process has been a source of debate in the aging research community. A recent study finds that LMNA, a gene targeted for mutation in Hutchinson Gilford Progeria Syndrome, may control the onset of aging-associated decline in normal fibroblasts.
متن کاملProgeria: a cell culture study on aging.
Progeria is an autosomal recessive disorder showing precocious senility. The cultured skin fibroblast from both the homozygous affected individual and the heterozygous parents can be distinguished from normals by decreased cell growth in culture. Mitotic activity, DNA synthesis, and cloning efficiency are markedly reduced.
متن کاملProgeria Syndrome Mechanisms of Premature Vascular Aging in Children With Hutchinson-Gilford Progeria Syndrome
Hutchinson-Gilford progeria syndrome is a rare, segmental premature aging syndrome of accelerated atherosclerosis and early death from myocardial infarction or stroke. This study sought to establish comprehensive characterization of the fatal vasculopathy in Hutchinson-Gilford progeria syndrome and its relevance to normal aging. We performed cardiovascular assessments at a single clinical site ...
متن کاملAging of Hutchinson-Gilford progeria syndrome fibroblasts is characterised by hyperproliferation and increased apoptosis.
Hutchinson-Gilford progeria syndrome is a rare genetic disorder that mimics certain aspects of aging prematurely. Recent work has revealed that mutations in the lamin A gene are a cause of the disease. We show here that cellular aging of Hutchinson-Gilford progeria syndrome fibroblasts is characterised by a period of hyperproliferation and terminates with a large increase in the rate of apoptos...
متن کاملHomozygous missense mutation in the lamin A/C gene causes autosomal recessive Hutchinson-Gilford progeria syndrome.
H utchinson-Gilford progeria syndrome (HGPS; MIM 176670) is an extremely rare genetic disorder displaying features reminiscent of premature senescence. 2 Typically, affected children appear normal at birth, but begin to develop characteristic symptoms within the first years of life such as failure to thrive, alopecia, lipodystrophy, and scleroderma-like skin changes. Though the first HGPS cases...
