Abnormal mRNA Expression Levels of Telomere-Binding Proteins Represent Biomarkers in Myelodysplastic Syndromes: A Case-Control Study

open access: yesTurkish Journal of Hematology, 2017
Objective: As evidence was shown that abnormal shortening of telomeres begins to accumulate in myelodysplastic syndrome (MDS) patients, this study was conducted to determine the relationship between the mRNA expression levels of telomere-binding proteins

Consequences of telomere dysfunction in fibroblasts, club and basal cells for lung fibrosis development

open access: yesNature Communications, 2022
Telomere dysfunction induced by TRF1 depletion in fibroblasts, club and basal cells did not lead to interstitial lung fibrosis, underscoring alveolar type II cells as the relevant cell type in pulmonary fibrosis.

Oleanolic acid inhibits mercury chloride induced-liver ferroptosis by regulating ROS/iron overload

open access: yesEcotoxicology and Environmental Safety, 2023
Mercury chloride can cause severe liver injury, which involves multiple mechanisms. Ferroptosis plays an important role in regulating the development and progression of liver pathology. Oleanolic acid (OA), a triterpenoid compound widely exists in fruits,

TRF1 and TRF2 binding to telomeres is modulated by nucleosomal organization [PDF]

open access: yesNucleic Acids Research, 2015
The ends of eukaryotic chromosomes need to be protected from the activation of a DNA damage response that leads the cell to replicative senescence or apoptosis. In mammals, protection is accomplished by a six-factor complex named shelterin, which organizes the terminal TTAGGG repeats in a still ill-defined structure, the telomere.

TRF1 uses a noncanonical function of TFIIH to promote telomere replication

open access: yesGenes & Development, 2022
Telomeric DNA challenges the replisome and requires TRF1 for efficient duplication. TRF1 recruits the BLM helicase, but BLM loss does not explain the extensive telomere fragility, ATR signaling, and sister telomere associations (STAs) induced by TRF1 deletion.

Therapeutic inhibition of TRF1 impairs the growth of p53‐deficient K‐RasG12V‐induced lung cancer by induction of telomeric DNA damage

open access: yesEMBO Molecular Medicine, 2015
Telomeres are considered anti‐cancer targets, as telomere maintenance above a minimum length is necessary for cancer growth. Telomerase abrogation in cancer‐prone mouse models, however, only decreased tumor growth after several mouse generations when ...

A siRNA-based screen for genes involved in chromosome end protection. [PDF]

open access: yesPLoS ONE, 2011
Telomeres are nucleoprotein complexes which protect the ends of linear chromosomes from detection as DNA damage and provide a sequence buffer against replication-associated shortening. In mammals, telomeres consist of repetitive DNA sequence (TTAGGG) and

TRF1 Controls Telomere Length and Mitotic Fidelity in Epithelial Homeostasis [PDF]

open access: yesMolecular and Cellular Biology, 2009
TRF1 is a component of the shelterin complex at mammalian telomeres; however, a role for TRF1 in telomere biology in the context of the organism is unclear. In this study, we generated mice with transgenic TRF1 expression targeted to epithelial tissues (K5TRF1 mice).

Creation of a novel telomere-cutting endonuclease based on the EN domain of telomere-specific non-long terminal repeat retrotransposon, TRAS1

open access: yesMobile DNA, 2010
Background The ends of chromosomes, termed telomeres consist of repetitive DNA. The telomeric sequences shorten with cell division and, when telomeres are critically abbreviated, cells stop proliferating.

Molecular Interplay of PARN and Telomerase: Tail Modifiers and Disease Implications

open access: yesWIREs RNA, Volume 17, Issue 4, July/August 2026.
Schematic representation of the molecular interplay between PARN, telomerase‐associated, and the involvement of p53 in regulating telomere maintenance and genome stability. The top panel shows how normal PARN levels are involved in regulating p53 levels and balanced telomerase activity through their regulatory interaction with TERC and TERRA, thus ...
