• Base catalysis as an alternative explanation for an apparent deuterium solvent isotope effect in the photochemical reactions of α,β-unsaturated esters
  作者：Alan C. Weedon

  DOI：10.1139/v84-332

  日期：1984.10.1

  conclusion is used to explain the apparently anomalous photochemistry of esters 1 and 5 in non-deuterated solvents. The results described also exemplify the use of a base to enhance the efficiency and to alter the direction of deconjugation in the photochemical conversion of α,β-unsaturated esters to their β,γ-unsaturated isomers.

  对 α,β-不饱和酯 3,4,4-三甲基-2-戊烯酸乙酯 1 和 3,4-二甲基-2-戊烯酸乙酯 4 的光化学反应的明显氘溶剂同位素效应是重新审查；得出的结论是，反应速率的变化可归因于所用溶剂中存在的碱性杂质对反应中间体（光化学产生的二烯醇）的拦截。该结论用于解释酯 1 和 5 在非氘化溶剂中明显异常的光化学。所描述的结果还举例说明了使用碱来提高效率并改变 α,β-不饱和酯到其 β,γ-不饱和异构体的光化学转化中的解偶联方向。

• Selenium Regulates Expression in Rat Liver of Genes for Proteins Involved in Iron Metabolism

  Suppression subtractive hybridization analysis in our laboratory recently revealed that transferrin mRNA may be elevated in Se-deficient rat liver. In this work, we compared expression in rat liver of genes for transferrin, transferrin receptor, ferritin light and heavy chains, and iron-regulatory proteins 1 and 2 in Se adequacy and deficiency. Weanling male Sprague-Dawley rats were fed Torula yeast diets supplemented with 0 or 0.15 mu g Se/kg diet as sodium selenite for 15 wk. Activity of cellular glutathione peroxidase was virtually abolished in Se-deficient rat liver, whereas activity of glutathione S-transferase was 43% higher than in Se-adequate liver. There were no differences in hematocrit, hemoglobin, or liver iron content. To examine differential gene expression, we used a multiplex relative reverse transcriptase-polymerase chain reaction method. Three of the six genes examined showed modest but consistent upregulation in Se deficiency. Transferrin mRNA was 30% more abundant in Se-deficient than in Se-adequate liver. For the transferrin receptor, the difference was 32%, and for iron regulatory protein 1, it was 63%. No consistent differences were observed for iron regulatory protein 2 or for ferritin light or heavy chain. These findings suggest a possible role for dietary Se in moderating iron metabolism.
