Insights

Hypertrophic cardiomyopathy (HCM) involves cellular and mitochondrial dysfunction. Targeting these mitochondrial issues offers promising new treatments for this heart condition, as current options are limited.

Area of Science:

  • Cardiology
  • Mitochondrial Biology
  • Genetics

Background:

  • Hypertrophic cardiomyopathy (HCM) is a heart disease marked by cellular and metabolic issues.
  • Mitochondrial dysfunction is a key factor in HCM pathogenesis, irrespective of the underlying cause.
  • Current HCM treatments primarily manage symptoms and prevent complications, lacking disease-modifying therapies.

Purpose of the Study:

  • To review the role of mitochondrial dysfunction in hypertrophic cardiomyopathy.
  • To explore potential therapeutic strategies targeting mitochondrial pathways for HCM.
  • To understand the biomolecular and genetic underpinnings of HCM for novel treatment development.

Main Methods:

  • Systematic literature search adhering to PRISMA-ScR guidelines.
  • Searches conducted in PubMed, Embase, and Scopus databases up to September 2023.
  • Inclusion of bibliographic references from relevant articles.

Main Results:

  • Mitochondrial dysfunction is a common pathway in HCM, linked to calcium handling, energy production, and oxidative stress.
  • Genetic mutations contribute to HCM, but their direct link to mitochondrial dysfunction requires further clarification.
  • Emerging therapies focus on enhancing mitochondrial function, including coenzyme Q, elamipretide, and metabolic interventions like ketosis.

Conclusions:

  • Mitochondrial dysfunction is a central mechanism in hypertrophic cardiomyopathy.
  • Targeting mitochondrial bioenergetics and metabolic pathways presents a promising avenue for novel HCM therapies.
  • Further research into the genetic and molecular basis of HCM is essential for advancing treatment options.

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...

Mitochondrial Membranes01:45

Mitochondrial Membranes

A single mitochondrion is a bean-shaped organelle enclosed by a double-membrane system. The outer membrane of mitochondria is smooth and contains many porins - the integral membrane transporters. Porins enable free diffusion of ions and small uncharged molecules through the outer mitochondrial membrane but limit the transport of molecules larger than 5000 Daltons. Further, the outer mitochondrial membrane forms a unique structure called membrane contact sites with other subcellular organelles,...

Mitochondria

Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

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...

Translocation of Proteins into the Mitochondria01:19

Translocation of Proteins into the Mitochondria

Mitochondrial precursors are translocated to the internal subcompartments via independent mechanisms involving distinct protein machineries called translocases.
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
