(Submitter supplied) Vascular dysfunction is one of the typical characteristics of aging, but its contributing roles to systemic aging and the therapeutic potential is lacking experimental evidence. Accumulating data suggest that the mechanisms underlying aging are similar to those governing Hutchinson-Gilford progeria syndrome (HGPS), a premature aging disease, in which affected patients succumb to cardiovascular diseases (CVDs). 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) To gain further insight into the biological effects of JH4, we investigated its impact on gene expression profiles. We defined a set of genes such as IL33, BRCA1, BLM, Rad51, IL6, IL8, and TNFSF18 whose expression is restored by JH4 treatment

(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) Our goal was to identify gene expression and functional differences between directly reprogrammed vascular cells derived from young and old individuals, as wells as from healthy and Hutchinson-Gilford Progeria Syndrome (HGPS) donors. We provided a full characterization of reprogrammed endothelial and smooth muscle cells by comparing their gene expression with both the original fibroblasts and primary vascular cells, showing that reprogrammed cells express key vascular cell-identity genes and contribute to the formation of in vitro 3D vascular structures. 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) Dietary intervention constitutes a feasible approach for modulating metabolism and improving healthspan and lifespan. Methionine restriction (MR) delays the appearance of age-related diseases and increases longevity in normal mice. However, the effect of MR on premature aging remains to be elucidated. Here, we describe that MR extends lifespan in two different mouse models of Hutchinson-Gilford progeria syndrome (HGPS) by reversing the transcriptome alterations in inflammation and DNA-damage response genes present in this condition. more...

(Submitter supplied) Protein deacetylase SIRT6 and protein kinase ATM both decline during aging, which are of importance in regualtion of glucose metabolism . To explore the mechnisms of SIRT6 and ATM in glycolysis, we analysed the gene expressions in murine embryonic fibroblast cells generated from wildtype, Sirt6-/-, or Atm-/- mice.

(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.
