A possible role of palmitic acid/Ca2+ (PA/Ca2+) complexes in the cyclosporin-insensitive permeability transition in mitochondria has been studied. It has been shown that in the presence of Ca2+, PA induces a swelling of mitochondria, which is not inh

From the hypothesis that in TNF-alpha-resistant cells the activity of mitochondrial phospholipase A2 could be reversed by a lysophospholipid acyltransferase, we report that the mitochondrial reacylation of phosphatidylcholine as phosphatidylethanolam

A mitochondrial hydrophobic component that forms Ca2+-induced nonspecific ion channels in black-lipid membranes (Mironova et al., 1997) has been purified and its nature elucidated. It consists of long-chain saturated fatty acids--mainly palmitic and

A hydrophobic, low-molecular weight component extracted from mitochondria forms aCa2+-activated ion channel in black-lipid membranes (Mironova et al., 1997). At pH 8.3–8.5, thecomponent has a high-affinity binding site for Ca2+ with a Kd of 8 × 10

We have previously reported that TNF induced changes in mitochondrial enzymes, one of which, succinate-dehydrogenase, is specifically activated in various TNF-sensitive cell lines. In an attempt to further characterize the mechanism of trans-membrane

We have studied TNF-induced changes in mitochondrial enzymes. One enzyme, succinate dehydrogenase (SDH), is specifically activated in TNF sensitive cells including U937 (human monocytic), WEHI-164 (murine fibrosarcoma), and ME-180 (human cervical car

Two membrane fractions of intermediate density between inner and outer mitochondrial membranes were isolated by density gradient centrifugation from osmotically lysed mitochondria and mitoplasts of liver. These fractions were characterized by the pre

Mitochondria were fractionated according to a procedure which allowed to get free outer and inner membrane plus two distinct contact sites between the two membranes. The data indicate that phospholipase A2 is localized in outer membrane contact sites
