A Case Report of Werner's Syndrome With a Novel Mutation From India.

Cureus 2020 May 8;12(5):e8025. Epub 2020 May 8.

Pathology, University of Washington, Seattle, USA.

Werner's syndrome (WS) or progeria adultorum is a heritable autosomal recessive disease in which the aging process is accelerated, just after puberty. It is caused by mutations in the WRN gene, which encodes a member of the RECQ family of DNA helicases and has a role in DNA repair. WS is being more appropriately recognized as a condition in which the lack of WRN protein results in an overall decline in the normal physiological functions of various organs rather than premature aging.

Sirtuin 1 and endothelial glycocalyx.

Pflugers Arch 2020 Jun 3. Epub 2020 Jun 3.

Renal Research Institute, New York Medical College at the Touro University, Valhalla, NY, USA.

Sirtuin1 deficiency or reduced activity comprises one of the hallmarks of diseases as diverse as chronic cardiovascular, renal, and metabolic, some malignancies, and infections, as well as aging-associated diseases. In a mouse model of endothelium-limited defect in sirtuin 1 deacetylase activity, we found a dramatic reduction in the volume of endothelial glycocalyx. This was associated with the surge in the levels of one of key scaffolding heparan sulfate proteoglycans of endothelial glycocalyx, syndecan-4, and specifically, its extracellular domain (ectodomain).

Genetic activation of Nrf2 reduces cutaneous symptoms in a murine model of Netherton syndrome.

Dis Model Mech 2020 Jun 1;13(5). Epub 2020 Jun 1.

Department of Biology, Institute of Molecular Health Sciences, ETH Zurich, 8093 Zurich, Switzerland

Netherton syndrome is a monogenic autosomal recessive disorder primarily characterized by the detachment of the uppermost layer of the epidermis, the It results from mutations in the gene, which codes for a kallikrein inhibitor. Uncontrolled kallikrein activity leads to premature desquamation, resulting in a severe epidermal barrier defect and subsequent life-threatening systemic infections and chronic cutaneous inflammation. Here, we show that genetic activation of the transcription factor nuclear factor (erythroid-derived 2)-like 2 (Nfe2l2/Nrf2) in keratinocytes of knockout mice, a model for Netherton syndrome, significantly alleviates their cutaneous phenotype.

Lamin A involvement in ageing processes.

Ageing Res Rev 2020 May 21;62:101073. Epub 2020 May 21.

CNR Institute of Molecular Genetics "Luigi Luca Cavalli-Sforza", Unit of Bologna, Bologna, Italy; IRCCS Istituto Ortopedico Rizzoli, Bologna, Italy. Electronic address:

Lamin A, a main constituent of the nuclear lamina, is the major splicing product of the LMNA gene, which also encodes lamin C, lamin A delta 10 and lamin C2. Involvement of lamin A in the ageing process became clear after the discovery that a group of progeroid syndromes, currently referred to as progeroid laminopathies, are caused by mutations in LMNA gene. Progeroid laminopathies include Hutchinson-Gilford Progeria, Mandibuloacral Dysplasia, Atypical Progeria and atypical-Werner syndrome, disabling and life-threatening diseases with accelerated ageing, bone resorption, lipodystrophy, skin abnormalities and cardiovascular disorders.

The molecular genetics of cellular senescence in the context of organismal aging.

Cas Lek Cesk 2020 ;159(2):88-92

Cellular senescence is a physiological state generally defined as a stable arrest of proliferation by preventing the cells from cycling. Unlike terminally differentiated cells, that also do not show proliferative activity, cellular senescence is stress induced and blocks the proliferation of cells with theoretical ability to divide (such as progenitor, stem or cancer cells) due to the activity of specific signaling pathways. The number of senescent cells increases during the ontogenesis of an organism. Read More

In contrast to the wealth of proven therapies for heart failure with reduced ejection fraction (HFrEF), therapeutic efforts in the past have failed to improve outcomes in heart failure with preserved ejection fraction (HFpEF). Moreover, to this day, diagnosis of HFpEF remains controversial. However, there is growing appreciation that HFpEF represents a heterogeneous syndrome with various phenotypes and comorbidities which are hardly to differentiate solely by LVEF and might benefit from individually tailored approaches.

Candesartan Neuroprotection in Rat Primary Neurons Negatively Correlates with Aging and Senescence: a Transcriptomic Analysis.

Mol Neurobiol 2020 Mar 7;57(3):1656-1673. Epub 2019 Dec 7.

Department of Pharmacology and Physiology, Georgetown University Medical Center, SE402 Med/Dent, 3900 Reservoir Road, Washington, DC, 20057, USA.

Preclinical experiments and clinical trials demonstrated that angiotensin II AT receptor overactivity associates with aging and cellular senescence and that AT receptor blockers (ARBs) protect from age-related brain disorders. In a primary neuronal culture submitted to glutamate excitotoxicity, gene set enrichment analysis (GSEA) revealed expression of several hundred genes altered by glutamate and normalized by candesartan correlated with changes in expression in Alzheimer's patient's hippocampus. To further establish whether our data correlated with gene expression alterations associated with aging and senescence, we compared our global transcriptional data with additional published datasets, including alterations in gene expression in the neocortex and cerebellum of old mice, human frontal cortex after age of 40, gene alterations in the Werner syndrome, rodent caloric restriction, Ras and oncogene-induced senescence in fibroblasts, and to tissues besides the brain such as the muscle and kidney.

Functional conservation of RecQ helicase BLM between humans and Drosophila melanogaster.

Sci Rep 2019 11 26;9(1):17527. Epub 2019 Nov 26.

Department of Human Science, Georgetown University Medical Center, Washington, DC, 20057, USA.

RecQ helicases are a family of proteins involved in maintaining genome integrity with functions in DNA repair, recombination, and replication. The human RecQ helicase family consists of five helicases: BLM, WRN, RECQL, RECQL4, and RECQL5. Inherited mutations in RecQ helicases result in Bloom Syndrome (BLM mutation), Werner Syndrome (WRN mutation), Rothmund-Thomson Syndrome (RECQL4 mutation), and other genetic diseases, including cancer.

NAD augmentation restores mitophagy and limits accelerated aging in Werner syndrome.

Nat Commun 2019 11 21;10(1):5284. Epub 2019 Nov 21.

Laboratory of Molecular Gerontology, National Institute on Aging, National Institutes of Health, Baltimore, MD, 21224, USA.

Metabolic dysfunction is a primary feature of Werner syndrome (WS), a human premature aging disease caused by mutations in the gene encoding the Werner (WRN) DNA helicase. WS patients exhibit severe metabolic phenotypes, but the underlying mechanisms are not understood, and whether the metabolic deficit can be targeted for therapeutic intervention has not been determined. Here we report impaired mitophagy and depletion of NAD, a fundamental ubiquitous molecule, in WS patient samples and WS invertebrate models. Read More

Ligand binding characteristics of the Ku80 von Willebrand domain.

DNA Repair (Amst) 2020 01 24;85:102739. Epub 2019 Oct 24.

Genome Integrity and Structural Biology Laboratory, National Institute of Environment and Health Sciences, National Institutes of Health, Research Triangle Park, NC, 27709, USA. Electronic address:

The N-terminal von Willebrand domain of Ku80 supports interactions with a Ku binding motif (KBM) that has been identified in at least three other DNA repair proteins: the non-homologous end joining (NHEJ) scaffold APLF, the modulator of retrovirus infection, MRI, and the Werner syndrome protein (WRN). A second, more recently identified Ku binding motif present in XLF and several other proteins (KBMX) has also been reported to interact with this domain. The isolated Ku80 von Willebrand antigen domain (vWA) from Xenopus laevis has a sequence that is 60% identical with the human domain, is readily expressed and has been used to investigate these interactions.
