(Submitter supplied) Progerin-expressing mice (HGPS-like) demonstrated increased energy metabolism and lipodystrophy. Increased mitochondrial biogenesis was found in adipose tissue from HGPS-like mice, whereas lamin C-only mice had fewer mitochondria. Thus we analyse which molecular pathways mediated the changes in adipose tissue caused by lamin C and progerin expression and the roles of these pathways in energy metabolism and aging.

(Submitter supplied) Hutchinson-Gilford progeria syndrome (HGPS) is a rare and fatal human premature aging disease1-5, characterized by premature atherosclerosis and degeneration of vascular smooth muscle cells (SMCs)6-8. HGPS is caused by a single-point mutation in the LMNA gene, resulting in the generation of progerin, a truncated mutant of lamin A. Accumulation of progerin leads to various aging-associated nuclear defects including disorganization of nuclear lamina and loss of heterochromatin9-12. more...

Analysis of iPSCs generated from fibroblasts from patients with Hutchinson-Gilford progeria syndrome (HGPS), a rare and fatal premature aging disease. Premature aging was recapitulated by differentiation of the HGPS-iPSCs. Results provide insight into molecular mechanisms underlying premature aging.

(Submitter supplied) Hutchinson-Gilford Progeria Syndrome (HGPS) is caused by a point mutation in the LMNA gene that activates a cryptic donor splice site and yields a truncated form of prelamin A called progerin. Small amounts of progerin are also produced during normal aging. Studies with mouse models of HGPS have allowed the recent development of the first therapeutic approaches for this disease. However, none of these earlier works have addressed the aberrant and pathogenic LMNA splicing observed in HGPS patients because of the lack of an appropriate mouse model. more...

(Submitter supplied) Hutchinson-Gilford Progeria Syndrome (HGPS) is a premature aging disorder that affects tissues of mesenchymal origin. Most individuals with HGPS harbor a de novo c.1824C>T (p.G608G) mutation in the gene encoding lamin A (LMNA), which activates a cryptic splice donor site resulting in production of a toxic protein termed “progerin”. Clinical manifestations include growth deficiency, lipodystrophy, sclerotic dermis, cardiovascular defects and bone dysplasia. more...

(Submitter supplied) Hutchinson-Gilford Progeria Syndrome (HGPS) is a segmental premature aging disorder caused by the accumulation of the truncated form of Lamin A known as Progerin within the nuclear lamina. Cellular hallmarks of HGPS include nuclear blebbing, loss of peripheral heterochromatin, defective epigenetic inheritance, altered gene expression, and senescence. To model HGPS using iPSCs, detailed genome-wide and structural analysis of the epigenetic landscape is required to assess the initiation and progression of the disease.

(Submitter supplied) Regular nuclear structure is critical for genome maintenance and proper gene expression, disorder of which has a causal role in aging. Accumulation of Progerin in Hutchinson-Gilford progeria syndrome (HGPS) disrupts the integrity of nuclear lamina and causes nuclear structure abnormalities, leading to premature aging. However, the nuclear structure/function relationships in HGPS cells have not been well addressed, and roles of nuclear sub-compartments for HGPS pathogenesis are rarely reported. more...

(Submitter supplied) Endothelial defects significantly contribute to cardiovascular pathology in the premature aging disease Hutchinson-Gilford progeria syndrome (HGPS). Using an endothelium-specific progeria mouse model, we identify a novel, endothelium-specific microRNA (miR) signature linked to the p53-senescence pathway and a senescence-associated secretory phenotype (SASP). Progerin-expressing endothelial cells exert profound cell-non-autonomous effects initiating senescence in non-endothelial cell populations and causing immune cell infiltrates around blood vessels. more...

(Submitter supplied) Hutchinson-Gilford progeria syndrome (HGPS) is a premature aging disease that is frequently caused by a de novo point mutation at position 1824 in LMNA. This mutation activates a cryptic splice donor site in exon 11, and leads to an in-frame deletion within the prelamin A mRNA and the production of a dominant negative lamin A protein, known as progerin. Here we show that HGPS cells experience genome-wide alterations in patterns of H3K27me3 deposition, changes in the associations of genomic loci with nuclear lamin A/C, and, at late passages, genome-wide loss of spatial compartmentalization of active and inactive chromatin domains that characterizes chromosome folding in normal cells. more...
