|January 31, 1998
Summary
Mitochondrial insufficiency causes widespread structural and functional issues across multiple organ systems. Skeletal muscle changes, particularly "ragged red fibres," are key diagnostic indicators for pathologists.
Area of Science:
- Mitochondrial biology and pathology
- Genetics and molecular biology
- Organ system physiology
Context:
- Mitochondrial insufficiency affects numerous tissues including the nervous system, muscles, and organs like the liver and kidneys.
- Pathologies arise from mutations in mitochondrial or nuclear DNA.
- Disease variants can be symptomatic or secondary to other conditions.
Purpose:
- To characterize nosological and syndromic forms of mitochondrial pathology.
- To analyze disease variants with symptomatic or presumed mitochondrial involvement.
- To highlight diagnostic criteria for pathologists.
Summary:
- Structural and functional disturbances linked to mitochondrial insufficiency are prevalent in various body systems.
- Key diagnostic features for pathologists include specific skeletal muscle changes, notably the "ragged red fibres" phenomenon.
- Clinicobiochemical and morphological data comparison is crucial for accurate diagnosis.
Impact:
- Provides a comprehensive overview of mitochondrial pathology across different organ systems.
- Emphasizes the diagnostic significance of skeletal muscle morphology.
- Underscores the importance of integrating clinical, biochemical, and morphological findings for diagnosis.

02:59Animal 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...
01:37Mitochondria
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,...
01:45Mitochondrial 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,...
01:28The 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...
01:48ATP Synthase: Mechanism
In animals, the mitochondrial F1F0 ATP synthase is the key protein that synthesizes ATP molecules through a complex catalytic mechanism. While the nuclear genome encodes the majority of ATP synthase subunits, the mitochondrial genome encodes some of the enzyme's most critical components. The formation of this multi-subunit enzyme is a complex multi-step process regulated at the level of transcription, translation, and assembly. Defects in one or more of these steps can result in decreased ATP...
01:20Inborn Errors of Metabolism
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...
