Rejuvenation Research, 2006
Given the constitutive expression of telomerase in the majority of human tumors, telomerase inhibition is an attractive, broad-spectrum therapeutic target for cancer treatment. Therapeutic strategies for inhibiting telomerase activity have included both targeting components of telomerase (the protein component, TERT, or the RNA component, TERC) or by ...

Trends in Biotechnology, 2001
There has been a vast increase in telomerase research over the past several years, with many different pre-clinical approaches being tested for inhibiting the activity of this enzyme as a novel therapeutic modality to treat malignancy. In this review, we will provide some basic background information about telomeres and telomerase and then discuss the ...

The unique biology of telomeres and telomerase plays important roles in many aspects of mammalian cell physiology. Over the past decade, several lines of evidence have confirmed that the maintenance of telomeres and telomerase participate actively in the pathogenesis of human cancer.

Science, 1995
The ribonucleoprotein enzyme telomerase synthesizes telomeric DNA by copying an internal RNA template sequence. The telomerase activities of the yeasts Saccharomyces castellii and Saccharomyces cerevisiae —with regular and irregular telomeric sequences, respectively—have now been identified ...

TELOMERASE IN UROLOGICAL MALIGNANCY
The Journal of Urology, 2001Telomerase is a ribonucleoprotein enzyme that compensates for the progressive erosion of chromosomal ends, called telomeres. In most somatic cells telomerase expression is repressed and telomeres progressively shorten after each cell division, causing cell senescence.

The past few years have brought a flood of new information to the telomerase field. The identification of multiple components of both the telomere and telomerase, the understanding of the importance of telomere maintenance to the long term viability of cells, and the demonstration of the utility of telomerase inhibition in limiting tumor cell growth ...

Trends in Biochemical Sciences, 2003
Recent data indicates that controlled in vivo synthesis of telomeric DNA is a 'ménage à trois', in which sister chromatid termini paired by telomere end-binding protein constitute a core substrate for a telomerase dimer. Such an arrangement could serve to fine tune synthesis of telomeric DNA and might ensure similar telomerase processivity for paired ...

Current Opinion in Genetics & Development, 1993
The ends of eukaryotic chromosomes are defined by specialized nucleoprotein complexes called telomeres. Telomeres impart stability to the genome and are of general interest due to their unique structure and unconventional mode of synthesis. Recent work has identified new components of the telomere complex and expanded our understanding of the role of ...

Telomeres, telomerase, and apoptosis
Biochemistry and Cell Biology, 2004Telomeres are specialized high-order chromatin structures that cap the ends of eukaryotic chromosomes. In vertebrates, telomeric DNA is composed of repetitions of the TTAGGG hexanucleotide, is bound to a set of specific proteins, and is elongated by the reverse transcriptase enzyme telomerase.

Introduction to Telomeres and Telomerase
2011Telomeres are ends of chromosomes that play an important part in the biology of eukaryotic cells. Through the coordinated action of the telomerase and networks of other proteins and factors, the length and integrity of telomeres are maintained to prevent telomere dysfunction that has been linked to senescence, aging, diseases, and cancer. The tools and
