  Introduction A variety of means, including UV irradiation, dNTP depletion, and oncogene activation at precancerous lesions, induce replication stress, which causes replication errors if left undealt with (Hills and Diffley, 2014, Zeman and Cimprich, 2014). Eukaryotic cells have developed the DNA

• Expression of MGMT in human cells

  2021-04-02

  

  Expression of MGMT in human Blebbistatin can be switched off by enzymatic methylation of a cytosine residue in the MGMT promoter sequence. In this regard, both MGMT and the mismatch repair function MLH1 belong to a subset of DNA repair genes that are subjected to epigenetic control. In consequence,

  2021-04-02

  

  Each nsP plays a distinct, defined and indispensable role in the replication of viral genome. nsP1 is a membrane associated protein which possesses S-adenosyl-L-methionine (SAM)-dependent methyltransferase (MTase) and guanylyltransferase (GTase) activities to catalyze the viral RNA capping reaction

  Our structures also provide new insights into CRTH2 drug development. The ligand binding pocket revealed by our structures comprises many aromatic residues and a few polar residues at the distal end. Correspondingly, most CRTH2 antagonists share a similar structural feature characterized by an aceta

  2021-04-02

  

  The quantification and monitoring of ChEs enzymatic activities have traditionally been associated to environmental studies in order to diagnose the exposure of non-target organisms to specific anti-cholinesterasic agents (Nunes, 2011). The importance of these enzymes as biomarkers of environmental c

  2021-04-01

  

  Fisetin (3,3′,4′,7-tetrahydroxyflavone) is a flavonol present in several fruits and vegetables such as grape, persimmon, strawberry, apple, and onion at concentrations rangeing from 2 to 160 μg/g. Fisetin is a well–known bioflavonoid with remarkable biological effects including chemopreventive/chem

  2021-04-01

  

  To study the effect of DDR inhibition by imatinib, nilotinib and dasatinib in a cellular environment we generated DDR1 and DDR2 expressing HEK293 cell lines by stable transfection. Of the five DDR1 splice variants we focused on the 1b variant whose over-expression has been associated with pulmonary

  2021-04-01

  

  Other GPCRs notable for changes in expression on CLL cells include upregulation of the thromboxane A2 receptor TBXA2R mRNA [61] and up and downregulation of mRNA and protein from the neurotensin receptors NTSR2 and NTSR1, respectively [62]. The Eμ-TCL1 mouse model of CLL has been used to study mult

  2021-04-01

  

  Introduction Melatonin mainly originates from the pineal gland (Reiter, 1991) and is well known for its physiological functions in the regulation of circadian rhythms (Cajochen et al., 2003) and as a potent free radical scavenger and broad-spectrum antioxidant in mammals (Paradies et al., 2010, T

  2021-04-01

  

  Protein degradation via UPP involves two steps. One step is the conjugation of multiple ubiquitin to a substrate. The other step is the degradation of tagged protein by the downstream 26S proteasome complex. Protein ubiquitination is the E1–E2–E3 enzymatic cascade (Hershko & Ciechanover, 1998). E1-a

  2021-04-01

  

  In the present study, we used linagliptin, one of the commercially available DPP-4 inhibitors, because it has more long-lasting inhibition of DPP-4 activity than other drugs of this class. We hypothesized that linagliptin may interact with intercellular components, not only with DPP-4 on the plasma

  2021-04-01

  

  AAG has a broad substrate specificity and besides 3-methyladenine can excise other altered purine residues, such as the minor lesions hypoxanthine and 1, N6-ethenoadenine from DNA. AAG initially activates these neutral base lesions by protonation of the base to allow for general S63845 catalysis [1

• Lymphocyte mobility and homing is modulated

  2021-03-30

  

  Lymphocyte mobility and homing is modulated by the chemoattractant receptor subfamily of G protein-coupled receptors (GPCRs) (Campbell et al., 2003, Rot and von Andrian, 2004). B cell migration and position are controlled to a large extent by the lymphoid chemokines CXCL13, CXCL12, CCL19, and CCL21

  TRAF1 and TRAF2 were initially identified as tumor necrosis factor receptor 2 (TNRF2)-associated components, TRAF4 was overexpressed in breast carcinoma cells, whereas TRAF3, TRAF5 and TRAF6 were discovered by their interaction with specific domains in the cytoplasmic tails of trans-membrane recepto

  The thermal behavior of the UV-sensitive nanocomposites was investigated by DSC before and after irradiation in an extended temperature range (from −40 to 250 °C). Fig. 4a shows the thermograms of the non-irradiated GNP-DNA/PDMS nanocomposites in comparison with a neat PDMS sample. The filler-loaded
