Summary
Telomeres protect chromosomes, but shorten with cell division. Reactivating telomerase in cancer cells offers a promising therapeutic target for novel anticancer drugs.
Area of Science:
- Genetics
- Molecular Biology
- Oncology
Background:
- Telomeres are protective caps on chromosomes, preventing DNA damage.
- Telomere shortening triggers cell senescence or death, but telomerase can confer immortality.
- Cancer cells often exhibit high telomerase activity, making it a cancer biomarker.
Purpose of the Study:
- To review novel anticancer targets focusing on telomere and telomerase function.
- To analyze the progress of telomere-related therapeutics in preclinical and clinical studies.
- To explore combination therapies involving telomere-targeting agents and traditional treatments.
Main Methods:
- Literature review of scientific publications and clinical trial data.
- Analysis of medicinal chemistry aspects, including drug delivery and structure-activity relationships.
- Discussion of a novel telomere assay for evaluating compounds.
Main Results:
- Telomerase is expressed in over 85% of human tumors, indicating its role in cancer.
- Telomere-related targets are actively being developed as anticancer therapeutics.
- Combination therapies show potential for enhanced cancer treatment efficacy.
Conclusions:
- Targeting telomere and telomerase function represents a promising strategy for cancer therapy.
- Ongoing research and clinical trials are advancing the development of these novel therapeutics.
- Medicinal chemistry plays a crucial role in optimizing drug bioavailability and efficacy for telomere-related treatments.

Telomeres and Telomerase
26.6K
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...

Replicative Cell Senescence
4.2K
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...

Replication in Eukaryotes
16.8K
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.

Targets for Drug Action: Overview

Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
