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.

Sperm Telomere Interactions Are Impaired in Testicular Cancer Before and After Adjuvant Therapy

Andrology, EarlyView.
ABSTRACT Background No study has yet explored telomere length or interaction in sperm nuclei of testicular cancer (TC) patients exposed to chemotherapy or radiotherapy. However, sperm telomere dynamics have emerged as a potential marker in male infertility.

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.

Integrating novel therapeutic strategies in myeloproliferative neoplasms: Driving disease‐directed progress

British Journal of Haematology, EarlyView.
Summary Over the past decade, there has been a substantial increase in the diversity and number of therapeutic options for myeloproliferative neoplasms (MPNs). While many remain within the clinical trial arena, the clinician and patient community have seen more approvals reaching the clinic and a rethink on how best we should be approaching these ...

circMAN1A2 as an Isoform‐Resolved Circular RNA Hub in Cancer

Cancer Science, EarlyView.
circMAN1A2 as an isoform‐resolved circular RNA hub in cancer. circMAN1A2 is generated by back‐splicing of MAN1A2 pre‐mRNA, with alternative circularization producing multiple isoforms, including the predominant circMAN1A2(2–5). Its mechanistic interfaces include miRNA‐associated regulation, RBP binding/proteostasis control, BSJ‐mediated RNA–RNA pairing,

An Alternate Splicing Variant of the Human Telomerase Catalytic Subunit Inhibits Telomerase Activity

Neoplasia: An International Journal for Oncology Research, 2000
Telomerase, a cellular reverse transcriptase, adds telomeric repeats to chromosome ends. In normal human somatic cells, telomerase is repressed and telomeres progressively shorten, leading to proliferative senescence.

Urinary Small Extracellular Vesicle DNA as a Biomarker for the Non‐Invasive Diagnosis of Bladder Cancer

Cancer Science, EarlyView.
Clinical application scenarios for the diagnosis of BC. A schematic diagram illustrating the use of sEV DNA liquid biopsy technology to differentiate between benign and bladder cancer patients. ABSTRACT Existing diagnostic technologies for bladder cancer (BC) suffer from low sensitivity, low specificity, or a lack of validation.

The role of telomere and telomerase in cancer and novel therapeutic target: narrative review

Frontiers in Oncology
Telomeres are dynamic complexes at the ends of chromosomes that are made up of protective proteins and tandem repeating DNA sequences. In the large majority of cancer cells, telomere length is maintained by telomerase, an enzyme that elongates telomeres.

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 ...

Splicing Factor Mutations in Clonal Hematopoiesis and Progression to Myeloid Neoplasms

Cancer Science, EarlyView.
Splicing factor (SF)‐mutant CH is characterized by relatively late emergence and accelerated clonal expansion in older individuals. This review summarizes its clonal dynamics, disease‐associated consequences of SF mutations in myeloid neoplasms, and candidate mechanisms that may contribute to age‐dependent selection.
