Distribution of total creatine (free creatine + phosphocreatine) between two subcellular macrocompartments – mitochondrial matrix space and cytoplasm – in heart and skeletal muscle cells was reinvestigated by using a permeabilized cell technique.

2,4 dinitrophenol-uncoupling effect on ?? in living hepatocytes depends on reducing-equivalent supply

Autor: Xavier Ronot, C. Keriel, Céline Filippi, Véronique Nogueira, Brigitte Sibille, Xavier Leverve

Publikováno v: Cytometry. 32:102-108

Mitochondrial uncouplers, such as 2,4 dinitrophenol (DNP), increase the cellular respiration by decreasing mitochondrial membrane potential (delta psi). We show that this respiratory effect can be transient or even prevented in isolated liver cells d

Is oxygen supply sufficient to induce normoxic conditions in isolated rat heart?

Autor: Coralie Poizat, P. Cuchet, C. Keriel

Publikováno v: Basic Research in Cardiology. 89:535-544

The aim of this study is to assess whether oxygen supply is sufficient to induce normoxic conditions in isolated rat hearts. Hearts are perfused with a Krebs medium supplemented with 11 mM glucose, 0.6 mM lactate, 0.06 mM pyruvate, non delipidated al

Modulation of fatty acid-binding protein content of adult rat heart in response to chronic changes in plasma lipid levels

Autor: Coralie Poizat, Y. F. De Jong, C. Keriel, M. M. Vork, P. Cuchet, A. Garnier, J. F. C. Glatz

Publikováno v: Molecular and Cellular Biochemistry. 123:107-112

The aim of this work was to study in the adult rat heart the effect of modifications of fatty acid (FA) supply on the content of cytoplasmic fatty acid-binding protein (H-FABPc). To modify the amount of circulating lipids, three different treatments

Influence of fatty acid backdiffusion on compartmental analysis of external detection curves obtained with 123-iodohexadecenoic acid in isolated rat heart

Autor: Coralie Poizat, F. Cand, P. Cuchet, C. Keriel, F. Dubois, A. Garnier

Publikováno v: Nuclear Medicine and Biology. 20:297-306

In isolated rat hearts, we investigated a possible backdiffusion of fatty acids and tried to determine whether it impaired our compartmental analysis of myocardial time-radioactivity curves obtained with an iodinated fatty acid, 16-iodo-9-hexadecenoi

An experimental model of hypoxia on isolated rat heart in recirculating system: study of fatty acid metabolism with an iodinated fatty acid

Autor: F. Dubois, P. Cuchet, F. Cand, Coralie Poizat, A. Garnier, C. Keriel

Publikováno v: Archives Internationales de Physiologie, de Biochimie et de Biophysique. 101:347-356

An experimental model of hypoxia was developed on isolated rat heart to study the effects of hypoxia on cardiac performance and metabolism. Fatty acid (FA) metabolism was explored by external detection with a labelled FA, iodohexadecenoic acid (IHA).

The intramyocardial fate of [1-14C] palmitate, iodopalmitate and iodophenylpentadecanoate in isolated rat hearts. A contribution to the choice of an iodinated fatty acid as a tracer of myocardial metabolism
