Oxidative stress, telomeres and cellular senescence: What non-drug interventions might break the link? [PDF]
, 2020 Telomeres are higher order structures that cap and protect chromosome ends. Telomeric DNA naturally shortens during somatic cell division and as a result of oxidative stress.

Oncogene, 2019 Long-lived species Homo sapiens have evolved robust protection mechanisms against cancer by repressing telomerase and maintaining short telomeres, thereby delaying the onset of the majority of cancer types until post-reproductive age.

TP53 R249S mutation in hepatic organoids captures the predisposing cancer risk
Hepatology, EarlyView., 2022 The systematic approach in elucidating the gain‐of‐function (GOF) roles of TP53 mutations in early liver carcinogenesis. Unique downstream targets of TP53 L3 mutations were identified from chormatin immunoprecipitation sequencing in HCC cell lines, followed by a series of validation assays to substantiate the exclusive transcriptional regulations ...

Mice with hyper-long telomeres show less metabolic aging and longer lifespans
Nature Communications, 2019 Telomere shortening is associated with aging. Here the authors analyze mice with hyperlong telomeres and demonstrate that longer telomeres than normal have beneficial effects such as delayed metabolic aging, increased longevity and less incidence of ...

F1000Research, 2016 Telomeres, the protective ends of linear chromosomes, shorten throughout an individual’s lifetime. Telomere shortening is a hallmark of molecular aging and is associated with premature appearance of diseases associated with aging.

Multiple cancer pathways regulate telomere protection
EMBO Molecular Medicine, 2019 Telomeres are considered as universal anti‐cancer targets, as telomere maintenance is essential to sustain indefinite cancer growth. Mutations in telomerase, the enzyme that maintains telomeres, are among the most frequently found in cancer. In addition,

Extra-telomeric functions of telomerase in the pathogenesis of Epstein-Barr virus-driven B-cell malignancies and potential therapeutic implications [PDF]
, 2018 The Epstein-Barr virus (EBV) is a ubiquitous human \u3b3-herpesvirus causally linked to a broad spectrum of both lymphoid and epithelial malignancies.

Telomeric RNAs are essential to maintain telomeres
Nature Communications, 2016 The telomeric long-non coding RNA, TERRA, has been proposed in the past to modulate different telomeric functions based on in vitrostudies. Here the authors show, using a genetic deletion approach, that TERRA is transcribed from the 20q subtelomere and ...

Haematologica, 2015 Aplastic anemia is a rare but life-threatening disorder characterized by cytopenia in at least two of the three blood lineages. A frequent feature of patients with aplastic anemia is that they have shorter telomeres than those of age-matched controls ...

Tianshengyuan-1 (TSY-1) regulates cellular Telomerase activity by methylation of TERT promoter. [PDF]
, 2016 Telomere and Telomerase have recently been explored as anti-aging and anti-cancer drug targets with only limited success. Previously we showed that the Chinese herbal medicine Tianshengyuan-1 (TSY-1), an agent used to treat bone marrow deficiency, has a ...
