Electron Transport Chain: Complex I and II01:46

Electron Transport Chain: Complex I and II

13.8K
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...

Animal Mitochondrial Genetics

7.6K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Mitochondrial Precursor Proteins01:39

Mitochondrial Precursor Proteins

2.6K
Mitochondrial precursors are partially unfolded or loosely folded polypeptide chains. Newly synthesized precursors are inhibited from spontaneously folding into their native conformation by the cytosolic chaperones, heat shock proteins 70 (Hsp70), and mitochondrial import stimulation factors (MSFs). Precursors bound to MSFs are guided to the TOM70-TOM37 receptors, while precursors bound to Hsp70  chaperones are targetted to TOM20-TOM22 receptor complexes.
Most of the mitochondrial...

Translocation of Proteins into the Mitochondria01:19

Translocation of Proteins into the Mitochondria

3.1K
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,...

Mitochondrial Membranes01:45

Mitochondrial Membranes

10.9K
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,...

Mitochondrial Protein Sorting01:39

Mitochondrial Protein Sorting

4.3K
Mitochondria are double-membrane organelles of the eukaryotes involved in cellular metabolism, signaling, ATP synthesis, and programmed cell death.  Each of these processes requires specific proteins and enzymes that must be correctly sorted to the right mitochondrial subcompartment for the proper functioning of the organelle.
Most of these mitochondrial proteins are encoded by the nucleus and imported to the mitochondria as unfolded or loosely folded precursors. Mitochondrial precursors...

Area of Science:

  • Biochemistry
  • Genetics
  • Cell Biology

Background:

  • Primary mitochondrial diseases (PMDs) are a heterogeneous group of genetic metabolic disorders.
  • These conditions stem from impaired mitochondrial oxidative phosphorylation (OXPHOS).
  • Mitochondrial genetics and cellular roles contribute to PMD complexity and diagnostic difficulties.

Purpose of the Study:

  • To outline characteristic features, or "red flags," indicative of primary mitochondrial diseases.
  • To provide physicians with an overview to navigate the complexities of diagnosing PMDs.
  • To simplify the understanding of mitochondrial medicine for clinical practice.

Main Methods:

  • This study is a narrative review.
  • It synthesizes information on common clinical indicators of PMDs.
  • Focuses on identifying diagnostic clues for physicians.

Main Results:

  • Identified peculiar clinical features ("red flags") that suggest PMDs.
  • These red flags aid in orienting diagnostic pathways.
  • The review offers a general overview of these indicators.

Conclusions:

  • Recognizing specific "red flags" is crucial for diagnosing primary mitochondrial diseases.
  • Understanding these features can simplify the diagnostic process for physicians.
  • This overview aims to demystify mitochondrial medicine and improve patient diagnosis.
