  In mammals, ribonucleotide reductase (RNR) is a unique enzyme that catalyzes the rate-limiting step of de novo synthesis of deoxyribonucleoside triphosphates (dNTPs).7, 8 Mammalian RNR consists of two homodimer subunits: the large catalytic dimer RRM1 and the small regulatory dimer RRM2 or RRM2B.

  Clinical potential of ET receptor biased ligands Is there a clinical need for ET receptor biased ligands? Evidence is strongest from research in epithelial ovarian cancer demonstrating that ET-1 stimulated ETA-mediated β-arrestin signalling leads to activation of the oncogenic mediator NF-κB [21]

  The hepatic cytochrome P450 (CYP450) superfamily is essential for metabolising foreign chemicals, fatty acids, vitamins, hormones and other compounds and consists of 18 subfamilies (Uno et al., 2012). The number of discovered CYP genes is increasing as a result of intense work with CYP450 gene struc

  The biological significance of DNA ligases is attributed to their function in DNA replication, recombination and/or DNA repair [1], [2]. In vertebrates, three different DNA ligases I, III and IV are recognized. DNA ligase I is essential for the Okazaki fragments’ ligation during lagging-strand DNA s

  G3DH has gained interest because of its broad substrate specificity and site-selective oxidation properties [9,10]. The conversion product, 3-ketoglycoside, possesses potential as a starting material for the chemical industry such as in polymer and surfactants because the keto group becomes a specif

  Acknowledgements The oxygenation level has an impact on various aspects of skin physiology, but mechanisms of these effects, including the role of hypoxia in epidermal differentiation, are still poorly understood. The main components of the hypoxia pathway are short-lived transcription factor H

  The Eph–ephrin signaling system has the ability to elicit bidirectional signaling, classical forward signaling by both Eph receptor via its intrinsic tyrosine kinase activity and reverse signaling by the transmembrane ephrin ligand via its cytoplasmic domain [38], [39]. Thus when EphB4 binds with ep

  Results Discussion Repair by NHEJ implicitly requires the pairing together of broken chromosome ends. A complex of Ku, XRCC4, DNA ligase IV, and XLF (PEC) is necessary and sufficient for this purpose (Reid et al., 2015). Here, we describe dynamic changes in this complex that are triggered by d

  Cell lines which possess microglial or neuronal properties are uncomplicated and convenient in vitro models for studying Leupeptin injury at the cellular and molecular levels. Microglial BV-2 cells are derived from the immortalized mouse microglia and exhibit many of the morphological, phenotypical

  Nearly 60years ago, the first two Wang Resin which catalyze the phosphorylation of proteins were discovered [1]. Protein phosphorylation was originally identified as a regulatory mechanism for the control of glycogen metabolism. Today it is clear that protein phosphorylation regulates most aspects o

Furthermore, a comparison of enzyme acti
