Piri Welcsh et al.
Methods (San Diego, Calif.), 108, 99-110 (2016-05-01)
Functional studies of the roles that DNA helicases play in human cells have benefited immensely from DNA fiber (or single molecule) technologies, which enable us to discern minute differences in behaviors of individual replication forks in genomic DNA in vivo....
Werner complex deficiency in cells disrupts the nuclear pore complex and the distribution of lamin B1
Li Zhi, et al.
Biochimica et Biophysica Acta - Molecular Cell Research, 1833(12), 3338-3345 (2013)
S Deepak Amalnath et al.
Indian journal of gastroenterology : official journal of the Indian Society of Gastroenterology, 36(4), 323-325 (2017-08-11)
Werner syndrome is a rare progeroid syndrome caused by the WRN gene mutation. It is characterized by a general appearance of premature aging, diabetes mellitus, and atherosclerosis, and an increased risk of malignancies. We report a patient who presented with...
Edmond M Chan et al.
Nature, 568(7753), 551-556 (2019-04-12)
Synthetic lethality-an interaction between two genetic events through which the co-occurrence of these two genetic events leads to cell death, but each event alone does not-can be exploited for cancer therapeutics1. DNA repair processes represent attractive synthetic lethal targets, because...
Linda J W Bosch et al.
Clinical cancer research : an official journal of the American Association for Cancer Research, 22(18), 4612-4622 (2016-04-29)
WRN promoter CpG island hypermethylation in colorectal cancer has been reported to increase sensitivity to irinotecan-based therapies. We aimed to characterize methylation of the WRN promoter, determine the effect of WRN promoter hypermethylation upon expression, and validate a previous report...
Katrin Friedrich et al.
Human genetics, 128(1), 103-111 (2010-05-06)
Werner syndrome (WS) is an autosomal recessive segmental progeroid syndrome caused by null mutations at the WRN locus, which codes for a member of the RecQ family of DNA helicases. Since 1988, the International Registry of Werner syndrome had enrolled...
Keffy Kehrli et al.
The Journal of biological chemistry, 291(47), 24487-24503 (2016-09-28)
The WRN helicase/exonuclease is mutated in Werner syndrome of genomic instability and premature aging. WRN-depleted fibroblasts, although remaining largely viable, have a reduced capacity to maintain replication forks active during a transient hydroxyurea-induced arrest. A strand exchange protein, RAD51, is...
Enzymatic and DNA binding properties of purified WRN protein: high affinity binding to single-stranded DNA but not to DNA damage induced by 4NQO
Orren D K, et al.
Nucleic Acids Research, 27(17), 3557-3566 (1999)
A Pipier et al.
Scientific reports, 11(1), 13469-13469 (2021-07-01)
G-quadruplexes (G4) are non-canonical secondary structures consisting in stacked tetrads of hydrogen-bonded guanines bases. An essential feature of G4 is their intrinsic polymorphic nature, which is characterized by the equilibrium between several conformations (also called topologies) and the presence of...
Veronika A Glukhova et al.
Journal of proteome research, 12(7), 3246-3254 (2013-05-30)
We describe the use of a targeted proteomics approach, selected reaction monitoring (SRM) mass spectrometry, to detect and assess RNAi-mediated depletion or "knockdown" of specific proteins from human cells and from Drosophila flies. This label-free approach does not require any...
Bidisha Saha et al.
Molecular genetics & genomic medicine, 1(1), 7-14 (2013-08-13)
Werner syndrome is a rare autosomal recessive disorder characterized by multiple features consistent with accelerated aging. It is caused by mutations in the WRN gene, which encodes a RecQ type helicase. To date, more than 70 disease-causing mutations have been...
Class I histone deacetylase HDAC1 and WRN RECQ helicase contribute additively to protect replication forks upon hydroxyurea-induced arrest
Kehrli K, et al.
The Journal of Biological Chemistry, 291(47), 24487-24503 (2016)
Zhi Li et al.
Biochimica et biophysica acta, 1833(12), 3338-3345 (2013-09-21)
From the surrounding shell to the inner machinery, nuclear proteins provide the functional plasticity of the nucleus. This study highlights the nuclear association of Pore membrane (POM) protein NDC1 and Werner protein (WRN), a RecQ helicase responsible for the DNA...
Bárbara Alcaraz Silva et al.
The Journal of biological chemistry, 289(33), 22771-22784 (2014-07-02)
Chromosome ends contain nucleoprotein structures known as telomeres. Damage to chromosome ends during interphase elicits a DNA damage response (DDR) resulting in cell cycle arrest. However, little is known regarding the signaling from damaged chromosome ends (designated here as "TIPs")...
