Summary
Telomerase, an enzyme found in most cancers but not healthy cells, is a promising target for new anticancer drugs and diagnostics. Inhibiting telomerase disrupts cancer cell chromosome maintenance, offering therapeutic potential.
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- Telomerase is upregulated in 80-90% of human cancers, but absent in normal tissues.
- This differential expression highlights telomerase as a potential cancer biomarker and therapeutic target.
Purpose of the Study:
- To review interdisciplinary efforts targeting telomere maintenance, focusing on telomerase.
- To discuss the therapeutic potential of telomerase inhibition and related strategies.
Main Methods:
- Review of current research on telomerase inhibitors targeting enzymatic function.
- Exploration of immunotherapy approaches using human telomerase reverse transcriptase (hTERT) peptides.
- Discussion of hTERT-promoter driven gene therapy strategies.
Main Results:
- Significant advances have been made in developing telomerase inhibitors and immunotherapies.
- Telomerase inhibition disrupts telomere maintenance, impacting cancer cell viability.
- The elevated telomerase levels in cancer cells offer diagnostic possibilities.
Conclusions:
- Targeting telomere maintenance, particularly through telomerase inhibition, holds significant therapeutic promise for cancer treatment.
- Interdisciplinary approaches are crucial for realizing the full potential of telomerase-based cancer therapies.
- Telomerase presents a viable target for novel anticancer drug development and diagnostics.

02:41Telomeres and Telomerase
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 DNA.

01:29Pharmacogenomics: Identification of New Drug Targets
Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...
01:29Replication in Eukaryotes
In eukaryotic cells, DNA replication is highly conserved and tightly regulated. Multiple linear chromosomes must be duplicated with high fidelity before cell division, so there are many proteins that fulfill specialized roles in the replication process. Replication occurs in three phases: initiation, elongation, and termination, and ends with two complete sets of chromosomes in the nucleus.

02:15Replicative Cell Senescence
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 the telomeric...
