Mitochondrial DNA copy number (mtDNA-CN) has been associated with a variety of aging-related diseases, including all-cause mortality. However, the mechanism by which mtDNA-CN influences disease is not currently understood. One such mechanism may be through regulation of nuclear gene expression via the modification of nuclear DNA (nDNA) methylation.

In ebook "Mitochondria: The dynamic organelle" the term mitochondrion is derived from Latin, with mitos meaning thread and chondrion meaning granules. Indeed, under the light microscope, mitochondria often appear as rods or granules within the cytoplasm. For decades after initial visualization of mitochondria by light microscopy, mitochondrial function remained clouded.

Nsa cytoplasmic male sterility (CMS) is a novel alloplasmic male sterility system derived from somatic hybridization between Brassica napus and Sinapis arvensis. Identification of the CMS-associated gene is a prerequisite for a better understanding of the origin and molecular mechanism of this CMS.

The genus Hosta is a group of economically appreciated perennial herbs consisting of approximately 25 species that is endemic to eastern Asia. Due to considerable morphological variability, the genus has been well recognized as a group with taxonomic problems. Chloroplast is a cytoplasmic organelle with its own genome, which is the most commonly used for phylogenetic and genetic diversity analyses for land plants.

Autophagy is a catabolic process to maintain intracellular homeostasis via removal of cytoplasmic macromolecules and damaged cellular organelles through lysosome-mediated degradation. Trehalose is often regarded as an autophagy inducer, but we reported previously that it could prevent ischemic insults-induced autophagic death in neurons.

Autophagy is an evolutionary conserved intracellular degradation and stress response mechanism that is mainly responsible for the breakdown and recycling of cytoplasmic materials, including long-lived proteins, protein aggregates, and damaged organelles.

Chapter 3 (part c) provides knowledge of the cytoplasm. This chapter describe the composition of the cytosol; discuss the structure and function of mitochondria; discuss the structure and function of ribosomes, the endoplasmic reticulum, and the Golgi apparatus, including functional interrelationships among these organelles; compare the functions of lysosomes and peroxisomes.

The vacuolar H + -ATPase (V-ATPase) is a multimeric enzyme complex that acidi®es organelles of the vacuolar system in eukaryotic cells. Proteins that interact with the V-ATPase may play an important role in controlling the intracellular localization and activity of the proton pump. The neuroendocrine-enriched V-ATPase accessory subunit Ac45 may represent such a protein as it has been shown to interactwith themembrane sector of theV-ATPase inonlya subset of organelles.

The development of targeted probes (based on the molecular engineering of luminescent or fluorescent proteins) has allowed the specific measure-ment of [Ca 2+ ] in intracellular organelles or cytoplasmic subdomains. This approach gave novel information on different aspects of cellular Ca 2+ homeostasis. Regarding mitochondria, it was possible to demonstrate that, upon physiological stimulation of cells, Ca 2+ is rapidly accumulated in the matrix.

We have investigated the direct effect of arachidonic acid on cholesterol transport in intact cells or isolated mitochondria from steroidogenic cells and the effect of cyclic-AMP on the specific release of this fatty acid inside the mitochondria. We show for the first time that cyclic-AMP can regulate the release of arachidonic acid in a specialized compartment of MA-10 Leydig cells, e.g.

It is widely accepted that chloroplasts derived from an endosymbiotic event in which an early eukaryotic cell engulfed an ancient cyanobacterial pro-karyote. During subsequent evolution, this new organelle lost its autonomy by transferring most of its genetic information to the host cell nucleus and therefore became dependent on protein import from the cytoplasm.

Ca 2+ regulates a multitude of cellular processes and does so by partition-ing its actions in space and time. In this review, we discuss how Ca 2+ responses are constructed from small quantal (elementary) events that have the potential to propagate to produce large pan-cellular responses. We review how Ca 2+ is compartmentalized both physically and functionally, and describe how each organelle has its own distinct Ca 2+ -handling prop-erties.

Adequate transport of large proteins that function in the nucleus is indis-pensable for cognate molecular events within this organelle. Selective pro-tein import into the nucleus requires nuclear localization signals (NLS) that are recognized by importin receptors in the cytoplasm.

Autophagy is an evolutionarily conserved lysosomal pathway used to degrade and recycle long-lived proteins and cytoplasmic organelles. This homeostatic ability makes autophagy an important pro-survival mechanism in response to several stresses, such as nutrient starvation, hypoxia, dam-aged mitochondria, protein aggregation and pathogens.

The endoplasmic reticulum (ER) and the Golgi apparatus both maintain their specific morphology, composition, and function in spite of the exchange of proteins and lipids between the two organelles through membrane trafficking. The morphology of the Golgi apparatus is closely linked to the balance between anterograde (ER-to-Golgi) and retrograde (Golgi-to-ER) transport. It has been reported that the inhibition of anterograde transport leads to the redistribution of Golgi components to the cytoplasm or the ER (Storrie et al., 1998; Ward et al., 2001; Miles et al., 2001).

By exchanging cytoplasmic proteins with exogenously added proteins, antibodies or cytosol that has been prepared from cells at distinct stages of the cell cycle or differentiation, or from disease states, we can modulate the intracellular environment and reconstitute various physiological phenomena in semi-intact cells. The semi-intact cell method was originally established by Dr. Simons’ group to study polarized vesicular trafficking in Madin-Darby canine kidney (MDCK) cells (Ikonen et al., 1995).
