Telomeres and Telomerase02:41

Telomeres 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.

Coronary Artery Disease I: Introduction

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...
Replicative Cell Senescence02:15

Replicative 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...
Longitudinal Studies01:26

Longitudinal Studies

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...
Psychoneuroimmunology: Cardiovascular Disease01:27

Psychoneuroimmunology: Cardiovascular Disease

Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

Area of Science:

  • Cardiovascular Science
  • Genetics
  • Cell Biology

Background:

  • Telomeres, protective DNA structures at chromosome ends, shorten with cell division.
  • Telomere length is a marker of cellular senescence and organismal aging.
  • Growing evidence suggests telomere attrition is involved in cardiovascular disease (CVD) pathogenesis.

Purpose of the Study:

  • To review recent data on telomere length and cardiovascular disease.
  • To assess telomere length as a potential novel cardiovascular risk marker.

Main Methods:

  • Literature review of studies investigating telomere length in cardiovascular disease.
  • Analysis of factors influencing telomere length, including cardiovascular risk factors.

Main Results:

  • Telomere shortening is observed in conditions such as atherosclerosis, hypertension, and myocardial infarction.
  • Telomere length may serve as a prognostic indicator for cardiovascular events.
  • Cardiovascular risk factors like smoking, obesity, and oxidative stress influence telomere length.

Conclusions:

  • Telomere length is significantly associated with cardiovascular disease onset, progression, and prognosis.
  • Telomere length warrants further investigation as a valuable biomarker for cardiovascular risk assessment.
