26724531BACKGROUND: Some LMNA mutations responsible for lipodystrophies, and some HIV-protease inhibitors (PIs) induce accumulation of farnesylated prelamin A and premature senescence in some cell types
26724531Patients with LMNA mutations or under PI-based therapy suffer from early atherosclerosis
26724531AIM: We studied whether altered expression of ZMPSTE24 could contribute to vascular cell dysfunction in response to LMNA mutations or PI treatments
26724531RESULTS: Fibroblasts from LMNA-mutated lipodystrophic patients (mutations R482W, D47Y or R133L) and peripheral blood mononuclear cells from PI-treated-HIV-infected patients expressed increased prelamin A and decreased ZMPSTE24, which was also observed in VSMCs overexpressing mutant LMNA or treated with PIs
26724531ZMPSTE24 silencing in native VSMCs recapitulated the mutant LMNA- and PI-induced accumulation of farnesylated prelamin A, oxidative stress, inflammation, senescence and calcification
26724531CONCLUSIONS: ZMPSTE24 downregulation is a major contributor in VSMC dysfunctions resulting from LMNA mutations or PI treatments that could translate in early atherosclerosis at the clinical level
26354777Depletion of LMNB1 or LMNA/C was sufficient to recapitulate some OIS features, including cell cycle exit and downregulation of NE proteins
25961132These structures are also dependent on association of lamin A/C, a canonical component of the nucleoskeleton that is mutated in myriad human diseases, including human segmental progeroid syndromes
25961132Since ITLs are associated with telomere stability and require functional lamin A/C, our study suggests a mechanistic link between cellular aging (replicative senescence induced by telomere shortening) and organismal aging (modeled by Hutchinson Gilford Progeria Syndrome)
24603298The LMNA gene codes for lamin-A and lamin-C proteins, which are structural components of the nuclear lamina

22541428Like HGPS cells, Lmna(-/-) and LmnaDelta9 fibroblasts have typically misshapen nuclei
22541428Unexpectedly, Lmna(-/-) or LmnaDelta9 mice that are also deficient for the inner nuclear membrane protein Sun1 show markedly reduced tissue pathologies and enhanced longevity
22470345Based on its senescence-dependent involvement in alternative splicing, we postulate that SRSF1 is a key marker of EC senescence, regulating the expression of alternative isoforms of target genes such as endoglin (ENG), vascular endothelial growth factor A (VEGFA), tissue factor (T3), or lamin A (LMNA) that integrate in a common molecular senescence program
22340368Human longevity and common variations in the LMNA gene: a meta-analysis
223403684 kb of the LMNA gene on a sample of long-lived individuals (LLI) (US Caucasians with age >/= 95 years, N=873) and genetically matched younger controls (N=443)
22340368These results suggest that LMNA variants may play a role in human lifespan
22297442Knowledge of the mechanism underlying prelamin A turnover is critical for the development of clinically effective protein inhibitors that can avoid accumulation to toxic levels without impairing lamin A/C expression, which is essential for normal biological functions
21535365The expression of E2F target genes, normally required for cell cycle progression, was downregulated after lamin A/C depletion but restored after the inactivation of p53
21208065Phenotypic changes in nuclear structure and heterochromatin, resulting from increased progerin production following overuse of a cryptic splice site in the LMNA gene have profound effects on cell cycle progression and DNA repair mechanisms
20819672Candidate genes including LMNA, ZMPSTE24, PPAR G, INSR and WRN were sequenced to screen for DNA variants
20819672The mRNA and protein expression levels of LMNA were examined in primary fibroblasts
20819672Nuclear abnormalities including nuclear blebs, mislocalization of lamin A/C were evident in the patient fibroblasts
20458013BACKGROUND: Hutchinson-Gilford progeria syndrome is a rare inherited disorder of premature aging caused by mutations in LMNA or Zmpste24 that disrupt nuclear lamin A processing, leading to the accumulation of prelamin A
20069564This nuclear arrangement was influenced by deficiency of the histone methyltransferase SUV39h, LMNA deficiency, and the histone deacetylase inhibitor Trichostatin A (TSA)
20069564This association was increased by SUV39h deficiency and decreased by LMNA deficiency
20021393In both syndromes, alterations in specific genes have been identified, with mutations in the WRN and LMNA genes respectively being the most closely associated with each syndrome

19589617The organization of both lamin A/C and its inner nuclear membrane partner emerin are altered, eventually showing a honeycomb pattern upon immunofluorescence microscopy
19589617Altogether, these data suggest that the LMNA mutation p
19172989The LMNA gene encodes two major proteins of the inner nuclear lamina, lamins A and C, but not much is known about their expression levels
17612587Lipodystrophic syndromes associated with mutations in LMNA, encoding A-type lamins, and with HIV antiretroviral treatments share several clinical characteristics
17612587Nuclear alterations and prelamin A accumulation have been reported in fibroblasts from patients with LMNA mutations and adipocytes exposed to protease inhibitors (PI)
17612587As genetically altered lamin A maturation also results in premature ageing syndromes with lipodystrophy, we studied prelamin A expression and senescence markers in cultured human fibroblasts bearing six different LMNA mutations or treated with PIs
17612587As compared to control cells, fibroblasts with LMNA mutations or treated with PIs had nuclear shape abnormalities and reduced proliferative activity that worsened with increasing cellular passages
17612587Adipose tissue samples from patients with LMNA mutations or treated with PIs also showed retention of prelamin A, overexpression of the cell cycle checkpoint inhibitor p16 and altered mitochondrial markers
17612587Thus, both LMNA mutations and PI treatment result in accumulation of farnesylated prelamin A and oxidative stress that trigger premature cellular senescence
17415412Finally, we showed that EWS interacts with lamin A/C and that loss of EWS results in a reduced lamin A/C expression
17415412Furthermore, we demonstrate a novel role of EWS in cellular senescence, possibly through its interaction and modulation of lamin A/C
17274801The most extreme cases of apoptosis occur in cells derived from diseases with mutations in the tail region of the LMNA gene, such as Dunningan-type familial partial lipodystrophy and mandibuloacral dysplasia, and this correlates with a significant level of micronucleation in these cells
16816143The family of laminopathies is a fast-growing group of diseases caused by abnormalities in the structure or processing of the lamin A/C (LMNA) gene
16816143This review gives an overview of current knowledge on lamin structure and function and all known diseases associated with LMNA abnormalities
