Summary
The telomere-telomerase system is crucial for cancer cell survival. Targeting telomere maintenance offers a promising anticancer therapy strategy, but potential side effects require further investigation for clinical relevance.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- The telomere-telomerase system plays a vital role in cancer cell biology.
- Telomere maintenance, often via upregulated telomerase activity, is essential for malignant cell perpetuation.
- This makes telomere maintenance a significant therapeutic target in oncology.
Purpose of the Study:
- To review critical aspects of telomere biology concerning anticancer therapy.
- To discuss the impact of conventional treatments on the telomere-telomerase system.
- To explore the combination of telomerase-directed therapy with existing cancer treatments.
Main Methods:
- Literature review focusing on telomere biology and cancer.
- Analysis of the effects of cytotoxic drugs, targeted agents, and radiotherapy on the telomere-telomerase system.
- Examination of potential combination therapies involving telomerase inhibition.
Main Results:
- Telomere maintenance is a fundamental characteristic enabling cancer cell immortality.
- Conventional anticancer treatments can affect the telomere-telomerase system.
- Combining telomerase-directed therapies with conventional treatments presents potential benefits and challenges.
Conclusions:
- Perturbing telomere biology, while a promising therapeutic avenue, carries risks of side effects in normal cells.
- Further research is needed to fully characterize the advantages and disadvantages of telomerase-directed therapies.
- Resolving these issues is crucial for establishing the clinical relevance of telomerase-targeted cancer treatments.

3.5K
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...

23.0K
In eukaryotic DNA replication, a single-stranded DNA fragment remains at the end of a chromosome after the removal of the final primer. This section of DNA cannot be replicated in the same manner as the rest of the strand because there is no 3’ end to which the newly synthesized DNA can attach. This non-replicated fragment results in gradual loss of the chromosomal DNA during each cell duplication. Additionally, it can induce a DNA damage response by enzymes that recognize single-stranded...

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
