Synergistic interaction of fatty acids and oxysterols impairs mitochondrial function and limits liver adaptation during nafld progression [PDF]

, 2018
The complete mechanism accounting for the progression from simple steatosis to steatohepatitis in nonalcoholic fatty liver disease (NAFLD) has not been elucidated.

Germinal proto-mitochondria from rat liver

Biochemistry and Biophysics Reports, 2019
A number of properties of the smallest (less than 0.2 μm) germinal proto-mitochondria (PRMC) from rat liver have been studied. These PRMC were obtained by filtering the light fraction of hepatic mitochondria (MC) through calibrated millipore membranes. Germinal PRMC contain in general the same proteins as MC.

Phosphatidylserine biosynthesis in mitochondria from the Morris 7777 hepatoma.

Journal of Lipid Research, 1979
Mitochondria from the 7777 hepatoma incorporate substantial amounts of l-[U-(14)C]serine into phospholipid by a Ca(2+)-dependent base-exchange reaction. This reaction is virtually absent in normal liver mitochondria.

Ethanol Consumption and Liver Mitochondria Function

Neurosignals, 2001
The mitochondrion is the subcellular organelle affected earliest during the development of alcoholic liver disease. As a result of chronic ethanol consumption mitochondrial protein synthesis is decreased significantly due to a depression in the functioning of the mitochondrial ribosome.

Alanine Metabolism in Rat Liver Mitochondria [PDF]

European Journal of Biochemistry, 1978
In the presence of 2‐oxoglutarate, bicarbonate, Pi and ATP, rat liver mitochondria were found to metabolize alanine. The main products were glutamate, aspartate, malate and citrate. Pyruvate did not accumulate but reached a low steady‐state concentration. Addition of octanoate caused a strong stimulation of alanine metabolism and a concomitant decrease

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

The clinical significance of the arterial ketone body ratio as an early indicator of graft viabilityin human liver transplantation [PDF]

, 1991
Arterial ketone body ratio (AKBR) was measured sequentially in 84 liver transplantations (OLTx). These transplantation procedures were classified into 3 groups with respect to graft survival and patient condition at the end of the first month (Group A ...

The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Living unicellular eukaryote Tetrahymena pyriformis as a model for study of mitochondrial energetics in mammalian cells under conditions of reduced oxidative metabolism. [PDF]

, 2010
Some “animal-like” protozoa are used instead of mammalian cells in diverse investigations. _Tetrahymena pyriformis_ cells in stationary phase of growth and washed from oxidative substrates (_T.pyriformis_) function under conditions of ...

Coming together to define membrane contact sites. [PDF]

, 2019
Close proximities between organelles have been described for decades. However, only recently a specific field dealing with organelle communication at membrane contact sites has gained wide acceptance, attracting scientists from multiple areas of cell ...
