Glucocorticoids and Fat Mobilisation a Response to Stress

We can more easily understand the logic of the synergistic interactions of the GR and PPAR RXR signal pathways on mHS gene expression, when we realise that one of the functions of glucocorticoid release into the blood is in the response of starvation stress.21 Starvation partly parallels the situations of the suckling neonate or the adult on a high fat low carbohydrate diet in that all three situations result in elevated plasma free fatty acid concentrations.22,23 In the case of starvation,...

Roelofsen1, K. E. Niezen-Koning, E. A. A. Nollen2, and J. R. G. Kuipers Department of Pediatrics department of Internal Medicine Department of Radiobiology Groningen Utrecht Institute for Drug Exploration Groningen University, Groningen The Netherlands The mitochondrial outer membrane enzyme carnitine palmitoyltransferase 1 CPT1 is a main site of regulation of intracellular long-chain fatty acid transport. At least two isoforms of CPT1 are expressed in the body L-CPT1...

Recent Studies on the Possible Identity of Microsomal CATa

Although CATA can be solubilized from rat liver microsomes using mild detergents such as deoxycholate5 and reconstituted into liposomes of known phospholipid compo-sition10 without loss of activity, further purification of the enzyme away from other membrane components requires harsher conditions, which inactivate the enzyme. For example, substantial further purification can be achieved by extraction into 8mM CHAPS with 4 M urea followed by anion-exchange chromatography and gel filtration N. M....

Preface

In September 1991, Victor Zammit and I were in the Department of Biochemistry, the University of Cambridge, discussing our collaborative research project when we realized the potential value and need for a conference specifically concerned with fatty acid oxidation and ketogenesis. The idea, once seeded, was indulged and flourished into the first Fatty Acid Oxidation amp Ketogenesis FAOx amp K Conference that was held in the Department at Eastertime, 1992. It was attended by colleagues mainly...
