  • Biochemical Mechanisms of Thyroid Hormone Deiodination
    THYROID Volume 15, Number 8, 2005 © Mary Ann Liebert, Inc. Biochemical Mechanisms of Thyroid Hormone Deiodination George G.J.M. Kuiper, Monique H.A. Kester, Robin P. Peeters, and Theo J. Visser Deiodination is the foremost pathway of thyroid hormone metabolism not only in quantitative terms but also because thyroxine (T4) is activated by outer ring deiodination (ORD) to 3,3’,5-triiodothyronine (T3), whereas both T4 and T3 are inactivated by inner ring deiodination (IRD) to 3,3’,5-triiodothyronine and 3,3’- diiodothyronine, respectively. These reactions are catalyzed by three iodothyronine deiodinases, D1-3. Although they are homologous selenoproteins, they differ in important respects such as catalysis of ORD and/or IRD, deiodination of sulfated iodothyronines, inhibition by the thyrostatic drug propylthiouracil, and regulation during fetal and neonatal development, by thyroid state, and during illness. In this review we will briefly discuss recent developments in these different areas. These have resulted in the emerging view that the biological activity of thyroid hormone is regulated locally by tissue-specific regulation of the different deiodinases.

  • A Machine Learning Tool for Predicting Protein Function Anna
    The Woolf Classifier Building Pipeline: A Machine Learning Tool for Predicting Protein Function Anna Farrell-Sherman Submitted in Partial Fulfillment of the Prerequisite for Honors in Computer Science under the advisement of Eni Mustafaraj and Vanja Klepac-Ceraj May 2019 © 2019 Anna Farrell-Sherman Abstract Proteins are the machinery that allow cells to grow, reproduce, communicate, and create multicellular organisms. For all of their importance, scientists still have a hard time understanding the function of a protein based on its sequence alone. For my honors thesis in computer science, I created a machine learning tool that can predict the function of a protein based solely on its amino acid sequence. My tool gives scientists a structure in which to build a � Nearest Neighbor or random forest classifier to distinguish between proteins that can and cannot perform a given function. Using default Min-Max scaling, and the Matthews Correlation Coefficient for accuracy assessment, the Woolf Pipeline is built with simplified choices to guide users to success. i Acknowledgments There are so many people who made this thesis possible. First, thank you to my wonderful advisors, Eni and Vanja, who never gave up on me, and always pushed me to try my hardest. Thank you also to the other members of my committee, Sohie Lee, Shikha Singh, and Rosanna Hertz for supporting me through this process. To Kevin, Sophie R, Sophie E, and my sister Phoebe, thank you for reading my drafts, and advising me when the going got tough. To all my wonderful friends, who were always there with encouraging words, warm hugs, and many congratulations, I cannot thank you enough.

Abstract: Olive oil, which is commonly used in the Mediterranean diet, is known for its health benefits related to the reduction of the risks of cancer, coronary heart disease, hypertension, and neurodegenerative disease. These unique properties are attributed to the phytochemicals with potent antioxidant activities in olive oil. Olive leaf also harbours similar bioactive compounds. Several studies have reported the effects of olive phenolics, olive oil, and leaf extract in the modulation of thyroid activities. A systematic review of the literature was conducted to identify relevant studies on the effects of olive derivatives on thyroid function. A comprehensive search was conducted in October 2020 using the PubMed, Scopus, and Web of Science databases. Cellular, animal, and human studies reporting the effects of olive derivatives, including olive phenolics, olive oil, and leaf extracts on thyroid function were considered. The literature search found 445 articles on this topic, but only nine articles were included based on the inclusion and exclusion criteria. All included articles were animal studies involving the administration of olive oil, olive leaf extract, or olive pomace residues orally.

They are present in tissues throughout mental stages and tissues. This is especially true for 0 the body where they catalyse 3,5,3 -triiodothyronine (T3) amphibians, where the impact of D1 may be minimal. D2 production and degradation via, respectively, outer and inner and D3 expression and activity respond to thyroid status in ring deiodination. Three different types of iodothyronine an opposite and conserved way, while the response of D1 is deiodinases (D1, D2 and D3) have been identified in variable, especially in fish. Recently, a number of deiodinases vertebrates from fish to mammals. They share several have been cloned from lower chordates.

These specific characteristics seem very well In addition, the cephalochordate amphioxus also expresses conserved for D2 and D3, while D1 shows more evolutionary a non-selenodeiodinase.

  • Type 3 Lodothyronine Deiodinase: Cloning, in Vitro Expression, and Functional Analysis of the Placental Selenoenzyme
    Type 3 lodothyronine deiodinase: cloning, in vitro expression, and functional analysis of the placental selenoenzyme. D Salvatore, … , D L St Germain, P R Larsen J Clin Invest. 1995;96(5):2421-2430. https://doi.org/10.1172/JCI118299. Research Article Type 3 iodothyronine deiodinase (D3) catalyzes the conversion of T4 and T3 to inactive metabolites. It is highly expressed in placenta and thus can regulate circulating fetal thyroid hormone concentrations throughout gestation. We have cloned and expressed a 2.1-kb human placental D3 cDNA which encodes a 32-kD protein with a Km of 1.2 nM for 5 deiodination of T3 and 340 nM for 5' deiodination of reverse T3. The reaction requires DTT and is not inhibited by 6n- propylthiouracil. We quantitated transiently expressed D3 by specifically labeling the protein with bromoacetyl [125I]T3. The Kcat/Km ratio for 5 deiodination of T3 was over 1,000-fold that for 5' deiodination of reverse T3. Human D3 is a selenoenzyme as evidenced by (a) the presence of an in frame UGA codon at position 144, (b) the synthesis of a 32-kD 75Se-labeled protein in D3 cDNA transfected cells, and (c) the presence of a selenocysteine insertion sequence element in the 3' untranslated region of the mRNA which is required for its expression. The D3 selenocysteine insertion sequence element is more potent than that in the type 1 deiodinase or glutathione peroxidase gene, suggesting a high priority for selenocysteine incorporation into this enzyme. The conservation of this enzyme from Xenopus laevis tadpoles to humans implies an essential role for regulation of thyroid hormone inactivation during embryological development.
