Insights

Oxidative stress from reactive oxygen species (ROS) and impaired energy metabolism contribute to cardiovascular diseases (CVD), particularly with metabolic disorders. Targeting NADPH oxidases (NOX) may offer new therapeutic strategies.

Area of Science:

  • Biochemistry
  • Cardiovascular Research
  • Metabolic Disorders

Background:

  • Reactive oxygen species (ROS) and antioxidant imbalance are linked to cardiovascular diseases (CVD), exacerbated by metabolic conditions like diabetes and hypercholesterolemia.
  • NADPH oxidases (NOX) are key sources of ROS, influencing redox signaling in physiological and pathological cardiovascular processes such as fibrosis and hypertrophy.
  • Mitochondria increase protein and energy production under stress, correlating with elevated superoxide radicals, highlighting a role in pathological states.

Purpose of the Study:

  • To review the interplay between oxidative stress and energy metabolism in CVD, especially in the context of metabolic disorders.
  • To elucidate the mechanisms underlying the increased incidence of CVD in individuals with metabolic disorders.
  • To explore the relationship between NOX, energy metabolism, and ferroptosis in CVD.

Main Methods:

  • Literature review integrating recent data on oxidative stress, energy metabolism, and NOX in CVD.
  • Analysis of NOX-mediated modulatory mechanisms in maintaining energy homeostasis during pathological conditions.
  • Preliminary discussion on the correlation between NOX, energy metabolism, and ferroptosis.

Main Results:

  • Sustained ROS production and imbalanced antioxidant systems are implicated in CVD development, particularly with metabolic disorders.
  • NOX enzymes are significant contributors to ROS, mediating redox signaling in cardiovascular pathophysiology.
  • NOX4 plays a crucial role in modulating energy metabolism homeostasis under pathological stress.

Conclusions:

  • Understanding the interaction between oxidative stress and energy metabolism is vital for explaining CVD incidence in metabolic disorders.
  • Further research into NOX and energy metabolism crosstalk, including ferroptosis, could lead to novel therapeutic targets.
  • Targeting NOX pathways offers potential for developing effective management strategies for CVD.

Electron Transport Chain: Complex III and IV01:43

Electron Transport Chain: Complex III and IV

During the electron transport chain, electrons from NADH and FADH2 are first transferred to complexes I and II, respectively. These two complexes then transfer the electrons to ubiquinol, which carries them further to complex III. Complex III passes the electrons across the intermembrane space to Cyt c, which carries them further to complex IV. Complex IV donates electrons to oxygen and reduces it to water. As electrons pass through complexes I, III, and IV, the energy released aids the pumping...

Role of Reduced Coenzymes NADH and FADH₂

The energy released from the breakdown of the chemical bonds within nutrients can be stored either through the reduction of electron carriers or in the bonds of adenosine triphosphate (ATP). In living systems, a small class of compounds functions as mobile electron carriers, molecules that bind to and shuttle high-energy electrons between compounds in pathways. The principal electron carriers that will be considered originate from the B vitamin group and are derivatives of nucleotides; they are...

Pathophysiology of Cardiac Performance01:29

Pathophysiology of Cardiac Performance

Typical heart performance is influenced by heart rate, rhythm, myocardial contraction, and metabolism or blood flow. The cardiac muscle exhibits distinct electrophysiological features, including pacemaker activity and calcium channel control, which play a vital role in the heart's response to various drugs. The autonomic nervous system, comprising the sympathetic and parasympathetic branches, regulates heart rate. Sympathetic activation increases heart rate, while parasympathetic activation...

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 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...

Pathophysiology of Heart Failure01:17

Pathophysiology of Heart Failure

Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...
