2020-09-05
The pyrrolo[2,1-][1,4]benzodiazepines (PBDs) are a family of antitumour antibiotics that includes the natural products anthramycin and DC-81. They exert their cytotoxicity by covalently bonding to the exocyclic C2–NH group of guanine residues in the minor groove of DNA through their N10–C11 imine fu

2020-09-05
Similar to EGFR, another receptor tyrosine kinase (RTK), fibroblast growth factor receptor 4 (FGFR4), is gaining attention in the lung cancer setting. The protein expression of this receptor has been recently associated with a negative impact on lung cancer prognosis, supporting the idea that FGFR4

Crystallographic and NMR-based analyses have revealed that RINGs and U-boxes have a common mode of interaction with E2s (Fig. 2A). The key structural elements are two loop-like regions, which, in the case of RINGs, coordinate Zn. The loops surround a shallow groove formed by the central α-helix. Tog

Although shoulder dub-off on gun drills has significant influence on chip transportation behavior, most commercial gun drills adhere to a fixed design of 20° that has limited scientific basis. To determine the effects of shoulder dub-off on chip evacuation, 5 different angles ranging from 0° to 30°

The ribosomal synthesis of D-proteins is not currently feasible; the best effort undertaken so far was limited to the translational incorporation of two D-amino acids into the nascent protein chain by means of modified ribosomes (Dedkova et al., 2006). We therefore apply solid-phase peptide synthesi

Since Slaughter’s proposal of a genetic field defect concept for the explanation of the local relapse occurrence, much evidence has accumulated for its confirmation. The last ten years brought evidence that the genetic changes in the field are frequently accompanied by epigenetic aberrations. The ep

Yu et al. [24] also reported that extracting consortium of hydrolytic enzymes from sludge flocs performs better than costly single purified commercial enzyme. Thus, it is concluded from the above cited literature analysis that only few studies have been reported on extraction of enzymes from waste s

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

2020-09-04
The folate pathway plays an essential role in cell survival by generating 5, 10-methylene tetrahydrofolate as a one-carbon donor for the synthesis of deoxythymidine monophosphate (dTMP), purines, methionine and histidine. Disruption of this pathway leads to the critical deficiency of these key molec

The question remains, however as to the downstream signaling by Epacs that contributes to persistent sensitization of sensory neurons. Activation of the Ras family of GTPases by Epac1 (RapGEF3) or Epac2 (RapGEF4) (Bos, 2003, de Rooij et al., 1998) is linked to a number of downstream signaling effect

EP1–4 receptors belong to the family of G protein-coupled receptor (GPCR). Trafficking events such as externalization, internalization, recycling and degradation dynamically regulate GPCR cell surface density. A fast-rate of internalization and degradation reduces GPCR surface density to desensitize

Herein, in continuation of our interest in designing new DNA photocleavage agents [18], we report the synthesis, characterization and DNA binding and cleaving properties of a novel compound: trans-N,N-dimethyl-10,11-di(pyridin-4-ium)-10,11-dihydro-9,12-dioxobenzo[e]phenanthrene tetrafluoroborate (1)

The present study was the first to examine how COMT genotype and estradiol are associated with Imatinib functioning in healthy postmenopausal women. We hypothesized that with decreased circulating estradiol after menopause, the COMT genotype relationship to cognition would remain and perhaps become

2020-09-03
Gastrointestinal tone can be effectively modulated by cholinesterase inhibitors. As parasympathetic fibers release Thiorphan to contract the circular and longitudinal intestinal muscles, AChE inhibition can facilitate those actions. Postoperative ileus (delayed gastric emptying after surgery) can a
