A telomerase holoenzyme protein enhances telomerase RNA assembly with telomerase reverse transcriptase [PDF]
Nature Structural & Molecular Biology, 2005 Telomerase maintains the simple sequence repeats at chromosome ends, protecting cells from genomic rearrangement, proliferative senescence and death. The telomerase reverse transcriptase (TERT) and telomerase RNA (TER) alone can assemble into active enzyme in a heterologous cell extract, but the physiological process of telomerase biogenesis is more ...

The association between telomerase activity and expression of its RNA component (hTR) in breast cancer patients: the importance of DNase treatment [PDF]
Telomerase is a ribonucleoprotein enzyme that compensates for the telomere length shortening which occurs during the cell cycle. Telomerase activity has been detected in most tumours but not in somatic cells.

Telomere erosion in memory T cells induced by telomerase inhibition at the site of antigenic challenge in vivo. [PDF]
, 2004 The extent of human memory T cell proliferation, differentiation, and telomere erosion that occurs after a single episode of immune challenge in vivo is unclear.

How Structural Features Define Biogenesis and Function of Human Telomerase RNA Primary Transcript
Biomedicines, 2022 Telomerase RNA has been uncovered as a component of the telomerase enzyme, which acts as a reverse transcriptase and maintains the length of telomeres in proliferated eukaryotic cells.

The N Terminus of the OB Domain of Telomere Protein TPP1 Is Critical for Telomerase Action
Cell Reports, 2018 Summary: Telomerase recruitment to telomeres and enzymatic processivity are mediated by TPP1, an essential component of telomere integrity and telomerase function.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level
Aging and Cancer, EarlyView.This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Mice with Pulmonary Fibrosis Driven by Telomere Dysfunction
Cell Reports, 2015 Idiopathic pulmonary fibrosis (IPF) is a degenerative disease of the lungs with an average survival post-diagnosis of 2–3 years. New therapeutic targets and treatments are necessary.

Aging and Cancer, EarlyView.Cancer treatment is associated with measurable acceleration of biological aging across epigenetic, telomere, senescence, and immune biomarkers. However, biomarker validation and interventional strategies remain limited, especially in hematologic malignancies, underscoring the need for standardized multi‐omic aging assessments and adequately powered ...
