  2020-09-23

  

  To study the role of DNA–PK in the response to replication arrest, we used the DNA replication inhibitor aphidicolin (APH). APH, a mycotoxin isolated from Cephalosporium aphidicola, inhibits DNA replication by interacting with the replicating DNA polymerase α (pol α). APH specifically inhibits the a

  2020-09-23

  

  The inhibition of DNMT1 using 5-AZA-dC or DNMT1 siRNA increased TIMP2 protein and mRNA expression, suggesting that TIMP2 expression is down-regulated by DNA methylation in the HDFs. In addition, 5-AZA-dC treatment led to a dose-dependent decrease of DNMT1 protein expression. 5-AZA-dC is a cytosine a

  The 8 members in apple are similar in number to the 7 in Arabidopsis and the 8 in rice, but fewer than the 10 found in mammalian species. GenBank numbers have also been reported for DGK homologues from tomato (AW035995), maize (AY106320), wheat (BT009326), a Populus cross (BU828590), grape (CB981130

  The authentic PPase was purified from B. subtilis as described previously [21], whereas the recombinant enzyme was purified to homogeneity from E. coli by a simplified procedure including only phenyl-Sepharose CL-4B column chromatography and DEAE-HPLC [21]. About 26 mg of pure enzyme was obtained fr

  Conclusion The results of the present study demonstrate that cysteinyl leukotrienes LTC4, LTD4 and LTE4 cause moderate to marked whereas the dihydroxy leukotriene LTB4 causes small muscle contraction in the stomach in vitro. The LTD4-induced contraction is mediated by CysLT1 in fundus but by Cys

  In the course of our program, which was aimed at developing CRTH2 antagonists for the treatment of allergic diseases, we have been pursuing a new class of potent and selective CRTH2 antagonist lead based on the structures of CRTH2 antagonists known to date (, , ). Using a fused 6–6-membered ring sys

  Although CK2 phosphorylated Msn4 as well as Msn2 (Fig. 1A), the two CK2-dependent phosphorylation sites in Msn2 are not conserved in Msn4. Thus, Msn2 and Msn4 might be differently regulated by CK2-dependent phosphorylation. Msn2 and Msn4, which have 41% identity and similarity in size and amino Sulf

  Materials and methods Results Discussion Human Chk, a member of the Csk-family, was initially cloned from two different megakaryocytic cell lines [2], [3]. Structural comparison of human Chk with human Csk shows that human Chk has the additional N-terminal unique domain [2], [3], [25]. Chk

  2020-09-22

  

  Impulsive burying and freezing behaviors in response to aversive stimuli may represent attempts to avoid novel and/or aversive stimuli. These behaviors can be assessed utilizing the marble burying and conditioned fear tasks, respectively. For example, Wistar rats in proestrus and ovariectomized rats

  Introduction Enzymes have higher selectivity, specificity and efficiency than chemical catalysts. Due to their properties and their green chemistry, biocatalysts are widely used in food, textile and pharmaceutical industry [1], [2]. A high efficient biocatalyst for industrial applications must be s

  According to the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (NC-IUBMB, 1992), peptidases are divided into two classes, namely exopeptidases and endopeptidases, based on their actions on substrates and their active sites, respectively. Endopeptidases inclu

  Structure similarity searches were conducted using the standalone version of the DALI program with the query structures scanned against a local current version of the PDB that has all chains as separate entries (Holm and Sander, 1995). The structural hits for each query were collected, even if the D

  Concholepas concholepas, our model species for this study, is a marine gastropod found along the Chilean coast that has become commercially important [25], [26], [27]. Until now, the main focus of immunology related to C. concholepas is the production of a novel hemocyanin that has been useful for t
