Insights

Reactive oxygen species (ROS) play a dual role in cell signaling and disease. This review explores ROS in cardiovascular disease, focusing on cell death and potential antioxidant therapies.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Cardiology

Background:

  • Reactive oxygen species (ROS) act as crucial second messengers in physiological signaling.
  • Excessive ROS accumulation damages cellular components, contributing to various human diseases, including cardiovascular diseases.
  • Cardiovascular diseases pose significant health risks due to high morbidity and mortality rates.

Purpose of the Study:

  • To review the regulation of intracellular ROS.
  • To elucidate the role of ROS in the pathogenesis of cardiovascular diseases.
  • To examine ROS-induced programmed cell death and explore antioxidant strategies for cardiovascular disease treatment.

Main Methods:

  • Literature review and synthesis of existing research on ROS.
  • Analysis of signaling pathways modulated by ROS.
  • Investigation of the link between ROS, cell death, and cardiovascular pathology.

Main Results:

  • ROS are integral to cellular signaling but excessive levels induce molecular damage.
  • ROS production is closely implicated in the development and progression of cardiovascular diseases.
  • ROS-mediated cell death pathways are key contributors to cardiovascular pathogenesis.

Conclusions:

  • Understanding ROS regulation is critical for cardiovascular health.
  • Targeting ROS pathways offers potential therapeutic strategies for cardiovascular diseases.
  • Antioxidant interventions show promise in managing ROS-related cardiovascular conditions.

Necrosis01:16

Necrosis

Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...

Peroxisomes01:24

Peroxisomes

Peroxisomes are specialized organelles present in fungi, plant, and animal cells. It can vary in number, size, morphology, and activity depending on the type of tissue and the nutritional state of the cell. For example, cells with active lipid metabolism, such as adipocytes, neurons, and hepatocytes, have more peroxisomes than other cells in the body. Besides their primary role in breaking down complex organic molecules, peroxisomes can also synthesize specific macromolecules and participate in...

Electron Transport Chain: Complex I and II01:46

Electron Transport Chain: Complex I and II

The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...

Overview of Cell Death01:30

Overview of Cell Death

Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

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...

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...
