(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) 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) The premature aging disease Hutchinson-Gilford Progeria Syndrome (HGPS) is caused by constitutive production of progerin, a mutant form of the nuclear architectural protein lamin A1. Progerin is also sporadically expressed in wild type cells and has been linked to physiological aging. HGPS cells exhibit extensive nuclear defects including abnormal chromatin structure and increased DNA damage. At the organismal level, HGPS affects several tissues particularly of mesenchymal origin. 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.

Transformed cell lines were obtained by retroviral introduction of TERT (T), V12-HRAS (R) and SV40 large and small T antigens (S) of primary skin fibroblasts for HGPS patients (TRS-HGPS) and age-matched control wild-type individuals (TRS-WT) Abstract: Advanced age and DNA damage accumulation are strong risk factors for cancer. more...

Knock-down of BRD4 in this TRS-HGPS cell line (TRS-HGPS-shBRD4) was achieved by retroviral introduction of independent shRNAs (shBRD4-1 to -3) Abstract: Advanced age and DNA damage accumulation are strong risk factors for cancer. more...

TERT-Immortalized cell lines from the same sources were also generated. Abstract: Advanced age and DNA damage accumulation are strong risk factors for cancer. The premature-aging disorder Hutchinson Gilford Progeria Syndrome (HGPS) provides a unique opportunity to study the interplay between DNA damage and aging-associated tumor mechanisms, since HGPS patients do not develop tumors despite elevated levels of DNA damage. more...

(Submitter supplied) Aging increases the vulnerability to various diseases. The main goal of aging research is to find therapies that attenuate aging and alleviate aging-related diseases. In this study, we screened a nature product library for geroprotective compounds using Werner syndrome (WS) human mesenchymal stem cells (hMSCs), a premature aging model that we recently established. Ten candidate targets were identified and quercetin was further investigated due to its leading effects. more...

(Submitter supplied) Understanding the genetic and epigenetic bases of cellular senescence is instrumental to aging intervention. We performed genome-wide CRISPR/Cas9-based screens in two human mesenchymal precursor cell (hMPC) models of progeroid syndromes and identified hundreds of genes whose deficiency alleviated cellular senescence. Among them, KAT7, a histone acetyltransferase, ranked as a top hit in both models. Inactivation of KAT7 decreased H3 lysine 14 acetylation (H3K14ac), repressed p15INK4b transcription, and rejuvenated both physiologically and pathologically aged cells. Moreover, lentiviral vectors encoding Cas9/sg-Kat7 alleviated liver senescence and extended healthspan and lifespan of mice. Our findings demonstrate that CRISPR/Cas9-based genetic screening is a robust method for systematically uncovering unknown senescence genes, of which KAT7 may represent a new therapeutic target for aging intervention.
