Summary
Mitochondrial biogenesis, the creation of new mitochondria, is crucial in muscle. This review explores its molecular regulation in striated muscles, highlighting areas for future research in aging and exercise.
Area of Science:
- Biochemistry
- Molecular Biology
- Cellular Biology
Background:
- Mitochondrial biogenesis occurs in skeletal muscle with chronic use and cardiac muscle during growth.
- This process may be impaired with aging.
- Striated muscles exhibit changes in mitochondrial content during altered physiological states.
Purpose of the Study:
- To review the biochemical and molecular processes of mitochondrial biogenesis.
- To emphasize the regulation of mitochondrial biogenesis in striated muscles.
- To identify future research directions in the field.
Main Methods:
- Literature review of biochemical and molecular biology studies.
- Analysis of gene expression (nuclear and mitochondrial).
- Examination of protein and phospholipid synthesis and import.
Main Results:
- Mitochondrial biogenesis involves coordinated expression of nuclear and mitochondrial genomes.
- Protein and phospholipid synthesis, import, and integration are key steps.
- Regulation of these events is complex and requires further investigation.
Conclusions:
- Understanding mitochondrial biogenesis requires knowledge of biochemical and molecular techniques.
- Further research is needed at the molecular level to elucidate regulatory processes.
- This is a promising area with potential for new discoveries in muscle physiology.

Animal Mitochondrial Genetics
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 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,...
The Inner Mitochondrial Membrane
The inner mitochondrial membrane is the primary site of ATP synthesis. The inner membrane domain that forms a smooth layer adjacent to the outer membrane is called the inner boundary membrane. This domain contains membrane transporters that drive metabolites in and out of the mitochondria. In contrast, the inner membrane network that invaginates into the matrix space is called the cristae membrane. This domain accounts for principle mitochondrial function as it accommodates the protein...
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,...

Porin Insertion in the Outer Mitochondrial Membrane
Porins are beta-barrel proteins translocated to the mitochondrial outer membrane through the TOM complex into the intermembrane space. Porin precursors bind TIM chaperones within the intermembrane space and are guided to the Sorting and Assembly Machinery complex or SAM complex on the outer mitochondrial membrane.
Three models describe the assembly of porins by the SAM complex and their insertion into the outer membrane. Model 1 suggests that porins are assembled outside the SAM channel as the...

Formation of Muscle Fibers from Myoblasts
De novo myogenesis, or the formation of muscle fibers, begins during the early embryonic stages. The skeletal muscle is formed from somites– blocks of embryonic cell layers. The somites are further divided into dermatomes, myotomes, sclerotomes, and syndetomes. Among these, the myotomes give rise to muscle fibers.
Muscle progenitor cells (MPCs) are formed from the myotomes. MPCs express genes that encode the transcription factors Pax3 and Pax7. Along with Pax 3/7, other transcription factors...
