  • Markedly Inhibited 7-Dehydrocholesterol-Delta 7-Reductase Activity in Liver Microsomes from Smith-Lemli-Opitz Homozygotes
    Markedly inhibited 7-dehydrocholesterol-delta 7-reductase activity in liver microsomes from Smith-Lemli-Opitz homozygotes. S Shefer, … , T C Chen, M F Holick J Clin Invest. 1995;96(4):1779-1785. https://doi.org/10.1172/JCI118223. Research Article We investigated the enzyme defect in late cholesterol biosynthesis in the Smith-Lemli-Opitz syndrome, a recessively inherited developmental disorder characterized by facial dysmorphism, mental retardation, and multiple organ congenital anomalies. Reduced plasma and tissue cholesterol with increased 7-dehydrocholesterol concentrations are biochemical features diagnostic of the inherited enzyme defect. Using isotope incorporation assays, we measured the transformation of the precursors, [3 alpha- 3H]lathosterol and [1,2-3H]7-dehydrocholesterol into cholesterol by liver microsomes from seven controls and four Smith-Lemli-Opitz homozygous subjects. The introduction of the double bond in lathosterol at C- 5[6] to form 7-dehydrocholesterol that is catalyzed by lathosterol-5-dehydrogenase was equally rapid in controls and homozygotes liver microsomes (120 +/- 8 vs 100 +/- 7 pmol/mg protein per min, P = NS). In distinction, the reduction of the double bond at C-7 [8] in 7-dehydrocholesterol to yield cholesterol catalyzed by 7-dehydrocholesterol-delta 7- reductase was nine times greater in controls than homozygotes microsomes (365 +/- 23 vs 40 +/- 4 pmol/mg protein per min, P < 0.0001). These results demonstrate that the pathway of lathosterol to cholesterol in human liver includes 7- dehydrocholesterol as a key intermediate. In Smith-Lemli-Opitz homozygotes, the transformation of 7-dehydrocholesterol to cholesterol by hepatic microsomes was blocked although 7-dehydrocholesterol was produced abundantly from lathosterol.

  • TRP Channel Transient Receptor Potential Channels
    TRP Channel Transient receptor potential channels TRP Channel (Transient receptor potential channel) is a group of ion channels located mostly on the plasma membrane of numerous human and animal cell types. There are about 28 TRP channels that share some structural similarity to each other. These are grouped into two broad groups: Group 1 includes TRPC ("C" for canonical), TRPV ("V" for vanilloid), TRPM ("M" for melastatin), TRPN, and TRPA. In group 2, there are TRPP ("P" for polycystic) and TRPML ("ML" for mucolipin). Many of these channels mediate a variety of sensations like the sensations of pain, hotness, warmth or coldness, different kinds of tastes, pressure, and vision. TRP channels are relatively non-selectively permeable to cations, including sodium, calcium and magnesium. TRP channels are initially discovered in trp-mutant strain of the fruit fly Drosophila. Later, TRP channels are found in vertebrates where they are ubiquitously expressed in many cell types and tissues. TRP channels are important for human health as mutations in at least four TRP channels underlie disease. www.MedChemExpress.com 1 TRP Channel Inhibitors, Antagonists, Agonists, Activators & Modulators (-)-Menthol (E)-Cardamonin Cat.

  • Role of Proaggregatory and Antiaggregatory Prostaglandins in Hemostasis
    Role of proaggregatory and antiaggregatory prostaglandins in hemostasis. Studies with combined thromboxane synthase inhibition and thromboxane receptor antagonism. P Gresele, … , G Pieters, J Vermylen J Clin Invest. 1987;80(5):1435-1445. https://doi.org/10.1172/JCI113223. Research Article Thromboxane synthase inhibition can lead to two opposing effects: accumulation of proaggregatory cyclic endoperoxides and increased formation of antiaggregatory PGI2 and PGD2. The elimination of the effects of the cyclic endoperoxides by an endoperoxide-thromboxane A2 receptor antagonist should enhance the inhibition of hemostasis by thromboxane synthase blockers. We have carried out a series of double-blind, placebo-controlled, crossover studies in healthy volunteers to check if this hypothesis may be operative in vivo in man. In a first study, in 10 healthy male volunteers, the combined administration of the thromboxane receptor antagonist BM 13.177 and the thromboxane synthase inhibitor dazoxiben gave stronger inhibition of platelet aggregation and prolonged the bleeding time more than either drug alone. In a second study, in 10 different healthy male volunteers, complete inhibition of cyclooxygenase with indomethacin reduced the prolongation of the bleeding time by the combination BM 13.177 plus dazoxiben. In a third study, in five volunteers, selective cumulative inhibition of platelet TXA2 synthesis by low-dose aspirin inhibited platelet aggregation and prolonged the bleeding time less than the combination BM 13.177 plus dazoxiben.

    International Journal of Molecular Sciences Review Effect of Prostanoids on Human Platelet Function: An Overview Steffen Braune, Jan-Heiner Küpper and Friedrich Jung * Institute of Biotechnology, Molecular Cell Biology, Brandenburg University of Technology, 01968 Senftenberg, Germany; steff[email protected] (S.B.); [email protected] (J.-H.K.) * Correspondence: [email protected] Received: 23 October 2020; Accepted: 23 November 2020; Published: 27 November 2020 Abstract: Prostanoids are bioactive lipid mediators and take part in many physiological and pathophysiological processes in practically every organ, tissue and cell, including the vascular, renal, gastrointestinal and reproductive systems. In this review, we focus on their influence on platelets, which are key elements in thrombosis and hemostasis. The function of platelets is influenced by mediators in the blood and the vascular wall. Activated platelets aggregate and release bioactive substances, thereby activating further neighbored platelets, which finally can lead to the formation of thrombi. Prostanoids regulate the function of blood platelets by both activating or inhibiting and so are involved in hemostasis. Each prostanoid has a unique activity profile and, thus, a specific profile of action. This article reviews the effects of the following prostanoids: prostaglandin-D2 (PGD2), prostaglandin-E1, -E2 and E3 (PGE1, PGE2, PGE3), prostaglandin F2α (PGF2α), prostacyclin (PGI2) and thromboxane-A2 (TXA2) on platelet activation and aggregation via their respective receptors. Keywords: prostacyclin; thromboxane; prostaglandin; platelets 1. Introduction Hemostasis is a complex process that requires the interplay of multiple physiological pathways. Cellular and molecular mechanisms interact to stop bleedings of injured blood vessels or to seal denuded sub-endothelium with localized clot formation (Figure1).

  • Structural Basis for Human Sterol Isomerase in Cholesterol Biosynthesis and Multidrug Recognition
    ARTICLE https://doi.org/10.1038/s41467-019-10279-w OPEN Structural basis for human sterol isomerase in cholesterol biosynthesis and multidrug recognition Tao Long 1, Abdirahman Hassan 1, Bonne M Thompson2, Jeffrey G McDonald1,2, Jiawei Wang3 & Xiaochun Li 1,4 3-β-hydroxysteroid-Δ8, Δ7-isomerase, known as Emopamil-Binding Protein (EBP), is an endoplasmic reticulum membrane protein involved in cholesterol biosynthesis, autophagy, 1234567890():,; oligodendrocyte formation. The mutation on EBP can cause Conradi-Hunermann syndrome, an inborn error. Interestingly, EBP binds an abundance of structurally diverse pharmacolo- gically active compounds, causing drug resistance. Here, we report two crystal structures of human EBP, one in complex with the anti-breast cancer drug tamoxifen and the other in complex with the cholesterol biosynthesis inhibitor U18666A. EBP adopts an unreported fold involving five transmembrane-helices (TMs) that creates a membrane cavity presenting a pharmacological binding site that accommodates multiple different ligands. The compounds exploit their positively-charged amine group to mimic the carbocationic sterol intermediate. Mutagenesis studies on specific residues abolish the isomerase activity and decrease the multidrug binding capacity. This work reveals the catalytic mechanism of EBP-mediated isomerization in cholesterol biosynthesis and how this protein may act as a multi-drug binder. 1 Department of Molecular Genetics, University of Texas Southwestern Medical Center, Dallas, TX 75390, USA. 2 Center for Human Nutrition, University of Texas Southwestern Medical Center, Dallas, TX 75390, USA. 3 State Key Laboratory of Membrane Biology, School of Life Sciences, Tsinghua University, Beijing 100084, China. 4 Department of Biophysics, University of Texas Southwestern Medical Center, Dallas, TX 75390, USA.

  • The Effects of Phytosterols Present in Natural Food Matrices on Cholesterol Metabolism and LDL-Cholesterol: a Controlled Feeding Trial
    European Journal of Clinical Nutrition (2010) 64, 1481–1487 & 2010 Macmillan Publishers Limited All rights reserved 0954-3007/10 www.nature.com/ejcn ORIGINAL ARTICLE The effects of phytosterols present in natural food matrices on cholesterol metabolism and LDL-cholesterol: a controlled feeding trial X Lin1, SB Racette2,1, M Lefevre3,5, CA Spearie4, M Most3,6,LMa1 and RE Ostlund Jr1 1Division of Endocrinology, Metabolism and Lipid Research, Department of Medicine, Washington University School of Medicine, St Louis, MO, USA; 2Program in Physical Therapy, Washington University School of Medicine, St Louis, MO, USA; 3Pennington Biomedical Research Center, Baton Rouge, LA, USA and 4Center for Applied Research Sciences, Washington University School of Medicine, St Louis, MO, USA Background/Objectives: Extrinsic phytosterols supplemented to the diet reduce intestinal cholesterol absorption and plasma low-density lipoprotein (LDL)-cholesterol. However, little is known about their effects on cholesterol metabolism when given in native, unpurified form and in amounts achievable in the diet. The objective of this investigation was to test the hypothesis that intrinsic phytosterols present in unmodified foods alter whole-body cholesterol metabolism. Subjects/Methods: In all, 20 out of 24 subjects completed a randomized, crossover feeding trial wherein all meals were provided by a metabolic kitchen. Each subject consumed two diets for 4 weeks each. The diets differed in phytosterol content (phytosterol-poor diet, 126 mg phytosterols/2000 kcal; phytosterol-abundant diet, 449 mg phytosterols/2000 kcal), but were otherwise matched for nutrient content. Cholesterol absorption and excretion were determined by gas chromatography/mass spectrometry after oral administration of stable isotopic tracers.
