(Submitter supplied) The A-type lamins (lamin A/C), encoded by the Lmna gene, are important structural components of the nuclear lamina. Lmna mutations lead to degenerative disorders, including the premature aging disease Hutchinson-Gilford progeria syndrome (HGPS). In addition, altered lamin A/C expression is found in various cancers. Reports indicate that lamin A/C plays a role in DNA double strand break repair, but a role in DNA base excision repair (BER) has not been described. more...

(Submitter supplied) Using ATAC seq analysis, we showed that the MEFs with a knockout of Lmna gene (i.e., missing the lamin A/C nuclear scaffolding protein) (Lmna-/- MEFs) display a striking change in chromatin accessibility landscape (peak signals that are both up and down), both within and outside lamina-associated domains (LADs); moreover, there was a clear overrepresentation of peaks with a gain in chromatin accessibility (within and outside LADs) in the Lmna-/- MEFs, and within LADs compared to outside LADs.

(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) LMNA encodes nuclear Lamin A/C that tethers lamina-associated domains (LADs) to the nuclear periphery. Mutations in LMNA cause degenerative disorders including the premature aging disorder Hutchinson-Gilford progeria, but the mechanisms are unknown. We report that Ser22-phosphorylated (pS22) Lamin A/C was localized to the nuclear interior in human fibroblasts throughout the cell cycle. pS22-Lamin A/C interacted with a subset of putative active enhancers, not LADs, at locations co-bound by the transcriptional activator c-Jun. more...

(Submitter supplied) Hutchinson-Gilford Progeria Syndrome (HGPS) is a progeroid disease characterized by the early onset of some classically age-related phenotypes including arthritis, loss of body fat and hair and atherosclerosis. Cells from affected individuals express a mutant version of the nuclear envelope protein Lamin A (termed Progerin) and have previously been shown to exhibit prominent chromatin changes. Here, we identify epigenetic deregulation of lamina-associated domains (LADs) as a central feature in the molecular pathology of HGPS. 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...
