Development of a microarray based telomerase binding assay reveals unusual binding of a cytochalasin derivative

Scientific Reports
Telomerase reverse transcriptase is crucial for cellular development, regeneration, and disease processes. Strategies for both telomerase activation and inhibition have been intensively explored in the past decades.

Radiolabeled oligonucleotides targeting the RNA subunit of telomerase inhibit telomerase and induce DNA damage in telomerase-positive cancer cells [PDF]

, 2019
Telomerase is expressed in the majority (>85%) of tumours, but has restricted expression in normal tissues. Long-term telomerase inhibition in malignant cells results in progressive telomere shortening and reduction in cell proliferation.

Senotherapeutics for Knee Osteoarthritis

Medicinal Research Reviews, EarlyView.
ABSTRACT Osteoarthritis (OA) is a chronic disease that imposes a significant economic burden and deteriorates quality of life. Nevertheless, current therapeutic options for OA are limited to symptomatic remedies. As such, there is a high interest in novel methods for treating or preventing OA.

Immunohistochemical Detection of Telomerase (hTERT) Protein in Human Cancer Tissues and a Subset of Cells in Normal Tissues

Neoplasia: An International Journal for Oncology Research, 2001
We examined human telomerase reverse transcriptase (hTERT) protein distribution by immunohistochemistry in cultured cells and tissue sections. Cells with telomerase activity had nuclear positive signals whereas cells without telomerase activity did not ...

Catechins and Their Effect on the Gut Microbiome in Health and Cancer

Phytotherapy Research, EarlyView.
ABSTRACT Catechins are a group of flavonoids found primarily in green tea, fruits, and berries; they play a significant role in the modulation of the gut microbiota, thereby having an impact on gut health and cancer prevention. Owing to their low bioavailability, catechins are transformed by the gut microbiota into various bioactive metabolites such as

Minimized human telomerase maintains telomeres and resolves endogenous roles of H/ACA proteins, TCAB1, and Cajal bodies

eLife, 2016
We dissected the importance of human telomerase biogenesis and trafficking pathways for telomere maintenance. Biological stability of human telomerase RNA (hTR) relies on H/ACA proteins, but other eukaryotes use other RNP assembly pathways.

Early‐Life Telomere Length Negatively Covaries With Brood Size and Father Age, and Predicts Long‐Term Survival in Male Barn Swallows (Hirundo rustica)

Integrative Zoology, EarlyView.
In barn swallows, nestlings raised in larger broods or by older social fathers have shorter telomeres, and those with longer telomeres tend to live longer, suggesting that early‐life conditions may shape individual lifespan through telomere dynamics. ABSTRACT Parental decisions on breeding, such as brood size and timing of reproduction, influence the ...

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

EMBO 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 ...

The Regulation of Telomerase in Oncogenesis

Acta Naturae, 2009
The influence that the expression of the human (glial-derived neurotrophic factor (GDNF)) neurotrophic factor has on the morphology and proliferative activity of embryonic stem cells (SC) of a mouse with R1 lineage, as well as their ability to form embroid bodies (EB), has been studied.

Mepolizumab Modifies Blood Eosinophil Proteome and Transcriptome in Severe Eosinophilic Asthma

Allergy, EarlyView.
This study investigates the effect of mepolizumab on the proteomic and transcriptomic profile of blood eosinophils in SEA patients. Mepolizumab reduces the migratory capacity and effector‐related molecular signatures of circulating eosinophils in SEA patients.
