Telomeres and Cancer

Life, 2021
Telomeres cap the ends of eukaryotic chromosomes and are indispensable chromatin structures for genome protection and replication. Telomere length maintenance has been attributed to several functional modulators, including telomerase, the shelterin ...

The structural biology of the shelterin complex [PDF]

Biological Chemistry, 2018
Abstract The shelterin complex protects telomeric DNA and plays critical roles in maintaining chromosome stability. The structures and functions of the shelterin complex have been extensively explored in the past decades. This review summarizes the current progress on structural studies of shelterin complexes from different species.

Characterization of the DNA binding specificity of Shelterin complexes [PDF]

Nucleic Acids Research, 2011
The Shelterin complex associates with telomeres and plays an essential role in telomere protection and telomerase regulation. In its most abundant form, the complex is composed of six core components: TRF1, TRF2, POT1, TIN2, TPP1 and RAP1. Of these subunits, three can interact directly with either single-stranded (POT1) or double-stranded (TRF1, TRF2 ...

Shelterin complex and associated factors at human telomeres [PDF]

Nucleus, 2011
The processes regulating telomere function have major impacts on fundamental issues in human cancer biology. First, active telomere maintenance is almost always required for full oncogenic transformation of human cells, through cellular immortalization by endowment of an infinite replicative potential.

Protection of the Telomeric Junction by the Shelterin Complex. [PDF]

J Am Chem Soc
Abstract Shelterin serves critical roles in suppressing superfluous DNA damage repair pathways on telomeres. The junction between double-stranded telomeric tracts (dsTEL) and single-stranded telomeric overhang (ssTEL) is the most accessible region of the telomeric DNA.

Shelterin Complex at Telomeres: Implications in Ageing.

Clinical interventions in aging, 2020
Different factors influence the development‎ and control of ageing. It is well known that progressive telomere shorting is one of the molecular mechanisms underlying ageing. The shelterin complex consists of six telomere-specific proteins which are involved in the protection of chromosome ends.

Staging concept for aging management: Definition, mechanism, and coping strategies

VIEW, EarlyView.
We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...

The WHO Classification of Genetic Tumour Syndromes: Considerations for Genetics

Clinical Genetics, EarlyView.
The WHO Classification of Tumours underpins the diagnosis of neoplastic conditions. The new WHO classification of genetic tumour syndromes (GTS) provides international standards for their diagnosis. This diagram highlights the chromosomal distribution of the genes involved in the GTS covered in this classification.

The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome

Biological Reviews, Volume 101, Issue 4, Page 1877-1903, August 2026.
ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

Essential Role for Telomeric Repeat‐Binding Factor 2 in Cardiac Development and Function

FASEB BioAdvances, Volume 8, Issue 7, July 2026.
This schematic illustrates a paradigm shift in telomere biology, demonstrating that Trf2 is a mandatory orchestrator of heart development and function through pathways distinct from its canonical telomere protective role. ABSTRACT Telomere repeat‐binding factor 2 (Trf2) is essential for protecting our telomeres.
