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 ...

Unlocking the potential of stimuli‐responsive liquid crystal polymer bio‐interfaces for adaptive cell modulation

Responsive Materials, EarlyView.
This Perspective discusses the potential of stimuli‐responsive liquid crystal polymer bio‐interfaces in modulating cell behavior as next generation dynamic artificial scaffolds. Unlike current artificial biomaterials that have static properties, LCPs offer fast, reversible, and spatially programmable deformation that reflects the dynamic properties of ...

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 ...

Telomerase Is Processive [PDF]

Molecular and Cellular Biology, 1991
Telomerase synthesizes tandem repeats of the sequence d(TTGGGG) onto input d(TTGGGG)n primer oligonucleotides (C. W. Greider and E. H. Blackburn, Cell 43:405-413). An intrinsic RNA component of the enzyme provides the template for d(TTGGGG)n repeat synthesis [C. W. Greider and E. H. Blackburn, Nature (London) 337:331-337, 1989; G.-L. Lu, J. D. Bradley,

Liquid biopsy in genitourinary oncology: Current clinical applications and future prospects across prostate, bladder, and renal cancers

UroPrecision, EarlyView.
Abstract Liquid biopsy has emerged as a transformative approach in oncology, providing minimally invasive access to tumor‐derived biomarkers with applications across diagnosis, prognosis, therapeutic guidance, and disease monitoring. This literature review synthesizes evidence from 125 studies evaluating circulating tumor DNA, circulating tumor cells ...

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.

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.

Three‐dimensional patient‐derived endometriosis model for drug evaluation

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
In this study, we developed a coculturing model with stromal cells and epithelial organoids to mimic the endometriotic lesion and for further evaluation of drug effects. Abstract Introduction Endometriomsis (EMs) is a complex and chronic gynecological disease characterized by distressing symptoms.

Clinical and Genetic Landscape of Glioblastoma, IDH‐Wildtype With FGFR Gene Family Alterations

Cancer Science, EarlyView.
We analyzed 1076 cases of glioblastoma, IDH‐wildtype (GBM, IDH‐wt) using the C‐CAT genomic database to clarify the clinical and genetic features of FGFR alterations. FGFR::TACC fusions and FGFR1 mutations were identified in distinct subsets and were associated with unique co‐mutation patterns.

Phosphatase PPP1CC Regulates the First Lineage Segregation by GAS5 in Mouse Preimplantation Embryos

Cell Proliferation, EarlyView.
Subcortical GAS5 directs PPP1CC phosphatase spatiotemporal positioning during mouse morula‐blastocyst transition, controlling YAP dephosphorylation to drive first embryonic lineage specification. ABSTRACT The transcriptional effector of the Hippo signalling pathway, YAP, regulates the first lineage specification in mouse preimplantation embryos ...
