  Introduction Structure of the Ku heterodimer associated to DNA The atomic structure of the Ku heterodimer, alone and bound to a small DNA fragment, was recently determined (Walker et al., 2001) and has significantly improved our understanding of DNA recognition by DNA-PK holoenzyme (Fig. 3). B

  Then what is the solution to tackle DNA damage-induced metabolic decline? The culprit here may be not DNA damage signaling per se, but rather the persistent activation of the DNA damage signaling pathways due to age-related accumulation of DNA damage. DNA repair, including repair by NHEJ, is an esse

  Results To understand how Rad53 functions to maintain replisome integrity, we first analyzed newly synthesized leading- and lagging-strand DNA in wild-type (WT) and rad53-1 mutant cells using BrdU-IP-ssSeq, a method that detects synthesis of both leading and lagging strands (Yu et al., 2014).

  In this report, we present spectroscopic evidence on the effect of different solvents having proton acceptor and proton donor ability and pH of the medium on the abstraction of amino proton of PI (Scheme 1) for controlling the nonradiative rates. Despite the general utility of PI as a DNA intercalat

  2020-12-22

  

  In contrast to the methylation that is catalyzed exclusively by DNMTs, there have been suggested several pathways that could induce demethylation (Watt & Molloy, 1988). However, the existence and influencing of enzymes that promote active demethylation remains elusive. Studies aiming to gain more in

  2020-12-22

  

  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

  The only reported synthesis of the aminobicyclic core of is based on bis-alkylation of a 4-amino-5,6-dihydroxypyrmidine with dibromoethane. The likelihood of poor regiocontrol/reactivity in utilizing such a transformation for the synthesis of compounds with a substituent on the dioxinyl ring led us

  Several of the plant extracts that showed interaction with ERα and ERβ have differing reports concerning estrogenicity and receptor binding. Extracts of dong quai stimulated MCF-7 proliferation but failed to increase uterine weight or transactivate either ERα or ERβ in a cell assay (Amato et al., 20

  Compared to ET-1, all agonists tested showed a 2–4 fold bias for the G protein constrictor assay compared to the β-arrestin assay (Table 1). This preliminary analysis indicated that at least modest pathway bias for endogenous ET peptides is possible, however the physiological significance of this, i

  Primary renal PNET was first reported by Seemayer et al in 1975. The possible etiology of rPNET is based on the theory of neural cell intussusception in the kidney during development that initiates the tumorigenesis. rPNET most commonly affects young adults, with a mean age of 30.4 years and male pr

  Introduction Rhabdomyosarcoma (RMS) is a myogenic tumor that accounts for approximately 50% of all pediatric soft tissue sarcomas. Diagnostic criteria for RMS 16,16-Dimethyl Prostaglandin E2 on the validation of proteins of the skeletal muscle lineage, such as Desmin, MyoD or Myogenin [1]. RMS c

  As illustrated in Table 3, monocyclic PMX 205 receptor analogs were synthesized and evaluated. 2-Oxido-3H-1,2,3,5-oxathiadiazol analog 8 showed 15-fold less potent EP1 receptor affinity relative to 2b, while it showed 2.2-fold more potent antagonist activity. Oxadiazole-5-one analog 9 exhibited near

  Upon Edn ligand binding, endothelin receptors can induce a variety of intracellular signaling cascades leading to diverse cellular responses such as contraction in the case of smooth muscle cells, or cell growth and mitogenesis. Ednrs are expressed in a variety of cell types and tissues, for example

  TraM is one of two transfer proteins from pIP501 T4SS that have structural similarity to the A. tumefaciens VirB8 protein (Fercher et al., 2016, Goessweiner-Mohr et al., 2013), a central member of the inner membrane complex (Bailey et al., 2006, Guglielmini et al., 2014, Trokter et al., 2014).
