Telomeres and Telomerase02:41

Telomeres and Telomerase

22.8K
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 Senescence02:15

Replicative Cell Senescence

3.6K
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...

Oogenesis02:07

Oogenesis

63.2K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Maintenance of the ES Cell State01:14

Maintenance of the ES Cell State

2.1K
The cells of the blastocyst inner cell mass only remain pluripotent for a short time. This state of pluripotency and self-renewal can be maintained in embryonic stem (ES) cell culture by adding specific chemicals or growth factors to ensure the cells can continue dividing and later differentiate into different cell types. In some cases, the cells are grown on a feeder layer of differentiated cells, which provides the growth factors and extracellular matrix components necessary for stem cell...

Cancer Stem Cells and Tumor Maintenance02:40

Cancer Stem Cells and Tumor Maintenance

4.6K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

The Tumor Microenvironment02:17

The Tumor Microenvironment

6.4K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Summary

Telomere length is longer in women with endometriosis, and inhibiting telomere maintenance reduces endometrial cell proliferation. These findings suggest telomere maintenance plays a role in endometriosis development.

Area of Science:

  • Reproductive biology
  • Molecular genetics
  • Cancer biology

Background:

  • Endometriosis affects reproductive-age women, causing pain and infertility.
  • Current treatments are limited, and the disease's cause remains unknown.
  • This study explores the link between telomere maintenance and endometriosis.

Purpose of the Study:

  • To investigate the association between telomere maintenance and endometriosis development.
  • To determine the effect of telomere length on endometrial cell proliferation.
  • To identify the role of telomere maintenance genes in endometriosis.

Main Methods:

  • Telomere length was measured using fluorescence in situ hybridization (FISH).
  • Endometrial cell proliferation was assessed via MTT assay with a telomerase inhibitor (BIBR1532).
  • Bioinformatics analysis of telomere maintenance genes from the Telnet database was performed.

Main Results:

  • Endometriotic patients showed longer telomeres in eutopic endometria during proliferative and secretory phases.
  • Telomerase inhibition reduced epithelial and stromal cell proliferation.
  • Telomere maintenance genes were linked to hormone pathways, with differential expression in endometriosis.

Conclusions:

  • Telomere maintenance is implicated in endometriosis development.
  • Specific telomere maintenance genes are involved in the disease process.
  • A nomogram based on these genes shows predictive value for endometriosis.
