(Submitter supplied) Progeroid syndromes are rare genetic diseases with a majority of autosomal dominant transmission, the prevalence of which is less than 1 / 10,000,000. These syndromes caused by mutations in the LMNA gene encoding A-type Lamins belong to the group of disorders called laminopathies. Lamins are implicated in the architecture and function of the nucleus and  chromatin. Patients affected with progeroid laminopathies display accelerated ageing of mesenchymal stem cells (MSCs)-derived tissues associated with nuclear morphological abnormalities. more...

(Submitter supplied) HGPS is a rare premature ageing disease, caused by a mutation in the LMNA gene, which activates a cryptic splice site, resulting in the production of a mutant lamin A isoform, called progerin. Sporadic usage of the same cryptic splice site has been observed with normal physiological aging. As it is unknown how HGPS causes premature ageing defects, we set out to determine the gene signature of both young healthy individuals, old healthy individuals, as well as HGPS patients.

(Submitter supplied) Hutchinson Gilford Progeria Syndrome (HGPS) is a rare, sporadic genetic disease caused by mutations in the nuclear lamin A gene. In most cases the mutation creates an efficient donor-splice site that generates an altered transcript encoding a truncated lamin A protein, progerin. In vitro studies have indicated that progerin can disrupt nuclear function. HGPS affects mainly mesenchymal lineages but the shortage of patient material has precluded a tissue-wide molecular survey of progerin’s cellular impact. more...

(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...

(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...

(Submitter supplied) Analysis of serum starved prelamin A-accumulating hMSCs at gene expression level. The hypothesis tested in the present study was that prelamin A accumulation induces the dysregulation of genes that are essensial for cell survival under a stress condition such as serum starvation. The results provide important information about these genes and the functional categories that are dysregulated due to prelamin A accumulation in serum starved hMSCs.
