Progeroid laminopathies are accelerated aging syndromes caused by defects in nuclear envelope proteins. Accordingly, mutations in the LMNA gene and functionally related genes have been described to cause HGPS (Hutchinson-Gilford progeria syndrome), MAD (mandibuloacral dysplasia) or RD (restrictive dermopathy). Functional studies with animal and cellular models of these syndromes have facilitate...
A de novo G608G mutation in LMNA gene leads to Hutchinson-Gilford progeria syndrome. Mice lacking the prelamin A-processing metalloprotease, Zmpste24, recapitulate many of the progeroid features of Hutchinson-Gilford progeria syndrome. Here we show that A-type lamins interact with SUV39H1, and prelamin A/progerin exhibits enhanced binding capacity to SUV39H1, protecting it from proteasomal degr...
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 ...
Defining the relationship between ageing and cancer is a crucial but challenging task. Mice deficient in Zmpste24, a metalloproteinase mutated in human progeria and involved in nuclear prelamin A maturation, recapitulate multiple features of ageing. However, their short lifespan and serious cell-intrinsic and cell-extrinsic alterations restrict the application and interpretation of carcinogenes...
Progeria also known Hutchinson–Gilford progeria syndrome (HGPS), is an extremely rare genetic disorder. The prevalence of HGPS is 1 in 4-8 million newborns. Progeria causes premature, rapid aging shortly after birth present within the first year of life. Recently, de novo point mutations in the Lmna gene at position 1824 of the coding sequence have been found in persons with HGPS. Lmna encodes ...
Macnamara, B. G. P., Farn, K. T., Mitra, A. K., Lloyd, J. K., and Fosbrooke, A. S. (1970). Archives of Disease in Childhood, 45, 553. Progeria: case report with long-term studies of serum lipids. A girl with the typical features of progeria died at the age of 10 years from cardiac failure following repeated myocardial infarctions. Serial studies of the serum lipids were made from the age of 2 y...
