Abstract:
ABSTRACT:Muscle biopsy provides the best tissue to confirm a mitochondrial cytopathy. Histochemical features often correlate with specific syndromes and facilitate the selection of biochemical and genetic studies. Ragged-red fibres nearly always indicate a combination defect of respiratory complexes I and IV. Increased punctate lipid within myofibers is a regular feature of Kearns-Sayre and PEO, but not of MELAS and MERRF. Total deficiency of succinate dehydrogenase indicates a severe defect in Complex II; total absence of cytochrome-c-oxidase activity in all myofibres correlates with a severe

Abstract:
Sensorineural hearing loss (SNHL) becomes an inevitable worldwide public health issue, and deafness treatment is urgently imperative; yet their current curative therapy is limited. Auditory neuropathies (AN) were proved to play a substantial role in SNHL recently, and spiral ganglion neuron (SGN) dysfunction is a dominant pathogenesis of AN. Auditory pathway is a high energy consumption system, and SGNs required sufficient mitochondria. Mitochondria are known treatment target of SNHL, but mitochondrion mechanism and pathology in SGNs are not valued. Mitochondrial dysfunction and pharmacologica

Abstract:
Mitochondria are dynamic ATP-generating organelle which contribute to many cellular functions including bioenergetics processes, intracellular calcium regulation, alteration of reduction-oxidation potential of cells, free radical scavenging, and activation of caspase mediated cell death. Mitochondrial functions can be negatively affected by amyloidβpeptide (Aβ), an important component in Alzheimer’s disease (AD) pathogenesis, and Aβcan interact with mitochondria and cause mitochondrial dysfunction. One of the most accepted hypotheses for AD onset implicates that mitochondrial dysfunction and o

Abstract:
Cardiovascular diseases take a leading position in the structure of mortality in modern society. Most diseases are characterized by uncontrolled processes of oxidative stress, proteolysis, tissue and cellular hypoxia, which cause endothelial dysfunction. Tissue and cellular hypoxia accumulated with mitochondrial reactive forms of oxygen damaging lipoproteins, proteins, nucleic acids plays an important role in the pathogenesis of vascular aging. Cellular aging is characterized by a decrease in the number of mitochondria, a decrease in the number of copies of mitochondrial DNA, and the loss of m

Abstract:
Mitochondria control vitally important functions in cells, including energy production, cell signalling and regulation of cell death. Considering this, any alteration in mitochondrial metabolism would lead to cellular dysfunction and the development of a disease. A large proportion of disorders associated with mitochondria are induced by mutations or chemical inhibition of the mitochondrial complex I — the entry point to the electron transport chain. Subunits of the enzyme NADH: ubiquinone oxidoreductase, are encoded by both nuclear and mitochondrial DNA and mutations in these genes lead to ca

Abstract:
An explosion of new information about mitochondria reveals that their importance extends well beyond their time-honored function as the “powerhouse of the cell.” In this Perspectives article, we summarize new evidence showing that mitochondria are at the center of a reactive oxygen species (ROS)-dependent pathway governing the response to hypoxia and to mitochondrial quality control. The potential role of the mitochondrial genome as a sentinel molecule governing cytotoxic responses of lung cells to ROS stress also is highlighted. Additional attention is devoted to the fate of damaged mitochond

Abnormal mitochondrial morphology, especially fragmented mitochondria, and mitochondrial dysfunction are hallmarks of a variety of human diseases including heart failure (HF). Although emerging evidence suggests a link between mitochondrial fragmentation and cardiac dysfunction, it is still not well described which cardiac signaling pathway regulates mitochondrial morphology and function under pathophysiological conditions such as HF. Mitochondria change their shape and location via the activity of mitochondrial fission and fusion proteins. This mechanism is suggested as an important modulator

Abstract:
Symbiosis between the mitochondrion and the ancestor of the eukaryotic cell allowed cellular complexity and supported life. Mitochondria have specialized in many key functions ensuring cell homeostasis and survival. Thus, proper communication between mitochondria and cell nucleus is paramount for cellular health. However, due to their archaebacterial origin, mitochondria possess a high immunogenic potential. Indeed, mitochondria have been identified as an intracellular source of molecules that can elicit cellular responses to pathogens. Compromised mitochondrial integrity leads to release of m

The production of reactive oxygen species by mitochondria is implicated in mitochondrial dysfunction associated with a range of diseases and ageing. In addition, reactive oxygen species produced by mitochondria are involved in redox signalling pathways that modulate a number of cell processes.

Elucidating the mechanisms for declining bone quality can lead to better therapeutics. A vital, yet overlooked aspect of bone health is the role of mitochondrial metabolism in both bone physiology and pathology. We have found that the ability of stem cells to differentiate into bone forming osteoblasts is sensitive to mitochondrial dysfunction, and therefore preserving mitochondrial function is essential to maintaining bone quality.
