CaMKII induces permeability transition through Drp1 phosphorylation during chronic β-AR stimulation
β-adrenergic receptor signaling induces mitochondrial permeability transition pore (mPTP) opening. Here, Xuet al. show that this effect is mediated by phosphorylation of mitochondrial fission protein Drp1 by CamKII, which increases the frequency of ...

A new limit for blood metabolite analysis using 1H NMR spectroscopy
Human blood is the most widely used biospecimen in the clinic and the metabolomics field. While both mass spectrometry and NMR spectroscopy are the two premier analytical platforms in the metabolomics field, NMR exhibits several unsurpassed ...

Glucose promotes cell growth by suppressing branched-chain amino acid degradation
Hypertrophic cardiomyocytes switch their metabolism from fatty acid oxidation to glucose use, but the functional role of this change is unclear. Here the authors show that high intracellular glucose inhibits the degradation of branched-chain amino acids,

Ltc1 is an ER-localized sterol transporter and a component of ER-mitochondria and ER-vacuole contacts. [PDF]
Organelle contact sites perform fundamental functions in cells, including lipid and ion homeostasis, membrane dynamics, and signaling. Using a forward proteomics approach in yeast, we identified new ER-mitochondria and ER-vacuole contacts specified by an

Sarcopenia and cardiovascular diseases: A systematic review and meta‐analysis
Sarcopenia is an age‐related disease and is often accompanied by other diseases. Now, many studies have shown that cardiovascular diseases (CVDs) may raise the incidence rate of sarcopenia. Therefore, the purpose of this study was to conduct a systematic

Localization of TCA cycle dehydrogenases in the mitochondria [PDF]
The site of localization of TCA cycle dehydrogenases in mitochondria has been investigated by observing the dehydrogenase activities and fine structure of the fractionated samples after freezing and thawing or sonication of beef heart and rat liver ...

Humanin G (HNG) protects age-related macular degeneration (AMD) transmitochondrial ARPE-19 cybrids from mitochondrial and cellular damage. [PDF]
Age-related macular degeneration (AMD) ranks third among the leading causes of visual impairment with a blindness prevalence rate of 8.7%. Despite several treatment regimens, such as anti-angiogenic drugs, laser therapy, and vitamin supplementation ...

A crucial role of the mitochondrial protein import receptor MOM19 for the biogenesis of mitochondria [PDF]
The novel genetic method of "sheltered RIP" (repeat induced point mutation) was used to generate a Neurospora crassa mutant in which MOM19, a component of the protein import machinery of the mitochondrial outer membrane, can be depleted.

Decades ago, Otto Warburg observed that cancers ferment glucose in the presence of oxygen, suggesting that defects in mitochondrial respiration may be the underlying cause of cancer. We now know that the genetic events that drive aberrant cancer cell proliferation also alter biochemical metabolism, including promoting aerobic glycolysis, but do not ...

Mice Hemizygous for a Pathogenic Mitofusin-2 Allele Exhibit Hind Limb/Foot Gait Deficits and Phenotypic Perturbations in Nerve and Muscle. [PDF]
Charcot-Marie-Tooth disease type 2A (CMT2A), the most common axonal form of hereditary sensory motor neuropathy, is caused by mutations of mitofusin-2 (MFN2). Mitofusin-2 is a GTPase required for fusion of mitochondrial outer membranes, repair of damaged
