Telomeres and Telomerase02:41

Telomeres and Telomerase

23.9K
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...

Replication in Eukaryotes

14.2K
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.

Replicative Cell Senescence02:15

Replicative Cell Senescence

3.7K
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...

Translesion DNA Polymerases02:10

Translesion DNA Polymerases

10.1K
Translesion (TLS) polymerases rescue stalled DNA polymerases at sites of damaged bases by replacing the replicative polymerase and installing a nucleotide across the damaged site. Doing so, TLS allows additional time for the cell to repair the damage before resuming regular DNA replication.
TLS polymerases are found in all three domains of life - archaea, bacteria, and eukaryotes. Of the different classes of TLS polymerases, members of the Y family are fitted with specialized structures that...

Spreading of Chromatin Modifications02:25

Spreading of Chromatin Modifications

8.5K
The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.

Background:

  • Telomeres are protective DNA caps at chromosome ends, crucial for preventing DNA shortening during cell division.
  • Telomere biology disorders arise from pathogenic germline variants in genes regulating telomere maintenance.
  • Recent technological advancements facilitate the identification of more patients with these rare disorders.

Purpose of the Study:

  • To highlight the expanding understanding of telomere biology disorders.
  • To emphasize the broadened phenotypic spectrum associated with these conditions.
  • To underscore the importance of considering telomere biology disorders in patients with unexplained symptoms like lung fibrosis.

Main Methods:

  • Leveraging new technologies for genetic variant identification.
  • Clinical phenotyping of patients with suspected telomere biology disorders.
  • Analysis of genotype-phenotype correlations.

Main Results:

  • Increased identification of patients with telomere biology disorders due to technological progress.
