Assessing the effects of mitofusin 2 deficiency in the adult heart using 3D electron tomography [PDF]
The effects of mitofusin 2 (MFN2) deficiency, on mitochondrial morphology and the mitochondria-junctional sarcoplasmic reticulum (jSR) complex in the adult heart, have been previously investigated using 2D electron microscopy, an approach which is unable

The Mitochondrial Ca(2+) Uniporter: Structure, Function, and Pharmacology. [PDF]
Mitochondrial Ca(2+) uptake is crucial for an array of cellular functions while an imbalance can elicit cell death. In this chapter, we briefly reviewed the various modes of mitochondrial Ca(2+) uptake and our current understanding of mitochondrial Ca(2+)

Mitochondrial dysfunction: roles in skeletal muscle atrophy
Mitochondria play important roles in maintaining cellular homeostasis and skeletal muscle health, and damage to mitochondria can lead to a series of pathophysiological changes.

Smooth Muscle Cells Move With Mitochondria [PDF]
Vascular smooth muscle cells (SMCs) are essential components in blood vessel walls and responsible for maintenance of blood vessel structure and function. Normally, SMCs reside in medial layers of blood vessels and do not exhibit migration potential. Under pathological conditions, however, medial SMCs migrate to intimal space where they proliferate and

Impaired mitochondrial dynamics and bioenergetics in diabetic skeletal muscle. [PDF]
In most cells, mitochondria are highly dynamic organelles that constantly fuse, divide and move. These processes allow mitochondria to redistribute in a cell and exchange contents among the mitochondrial population, and subsequently repair damaged ...

Nitric oxide regulates skeletal muscle fatigue, fiber type, microtubule organization, and mitochondrial ATP synthesis efficiency through cGMP-dependent mechanisms [PDF]
Aim: Skeletal muscle nitric oxide–cyclic guanosine monophosphate (NO-cGMP) pathways are impaired in Duchenne and Becker muscular dystrophy partly because of reduced nNOSμ and soluble guanylate cyclase (GC) activity.

Mitochondrial content is regarded a useful feature to distinguish muscle-fiber types in terms of energy metabolism in skeletal muscles. Increasing evidence suggests that specific mitochondrial bioenergetic phenotypes exist in metabolically different ...

Flux control of cytochrome c oxidase in human skeletal muscle [PDF]
In the present work, by titrating cytochrome c oxidase (COX) with the specific inhibitor KCN, the flux control coefficient and the metabolic reserve capacity of COX have been determined in human saponin-permeabilized muscle fibers. In the presence of the

Mitochondrial dynamics–fusion, fission, movement, and mitophagy–in neurodegenerative diseases [PDF]
Neurons are metabolically active cells with high energy demands at locations distant from the cell body. As a result, these cells are particularly dependent on mitochondrial function, as reflected by the observation that diseases of mitochondrial ...

A histochemical study of the red and white muscle fibers Part III. Activity of the diphosphopyridine nucleotide diaphorase and triphosphopyridine nucleotide diaphorase in muscle fibers [PDF]
From the histochemical study of DPN and TPN diaphorase on the striated muscles of the cats, the following results were obtained. 1. M. gastrocnemius, which belongs to the white muscle by naked eye, consists of three types of muscle fibers distinguished ...
