  Acknowledgements The study of RING-type E3s continues to grow extremely rapidly. We regret that it was possible to only cite a fraction of the outstanding primary publications in this field. This work was supported by the National Institute of General Medical Sciences grants R01 GM088055 and R01

  2019-09-10

  

  Introduction O6-Methylguanine-DNA methyltransferase (MGMT) is a DNA-repair enzyme that specifically transfers alkyl adducts from the O6 position of guanine to the cysteine residue (Cys145) in its active site. In cancer cells, this ability of MGMT disrupts the cytotoxic actions of alkylating antic

  However, not all inhibitory profiles by metals can be a priori considered artifacts of the methodology used to quantify the activity of such enzymes. Metals can indeed interfere with cholinesterases, and the mechanisms are varied. The inhibitory effect of specific metals may derive from their abilit

  Chk 1 and Chk 2 mediated signaling act as a barrier to tumorigenesis It was hypothesized recently that early events during tumorigenesis, such as the overexpression of oncogenes, lead to a DNA-damage response which, in turn halts tumor progression [44], [45], [46]. The DNA-damage response is prop

  2019-09-09

  

  Estrogen receptors (ERs) belong to the third class of nuclear receptors (NR3) [23]. Two different forms of ER have been described, ERα and ERβ. They are coded by two distinct genes (ESR1 and ESR2, respectively) containing 8 transcribed exons that give rise to six conserved protein domains: domains A

  Conflict of interest statement Introduction Endothelins (ETs) are a family of multifunctional, naturally occurring peptides with long-lasting vasoconstrictor and pressor effects (Zhou et al., 2004). They are synthesized as a large protein, the pre-proET-1 or Big ET-1, which is subsequently cle

  2019-09-09

  

  In mammals, NETs contain DNA and antimicrobial proteins composed mainly of nuclear histones, granule-derived neutrophil elastase, myeloperoxidase, lactoferrin, pentraxin, and gelatinase among others [11], [46], [47], [48]. In fish, NETs-like structures have been observed, and DNA staining and immuno

  Even more unambiguous was the relative contribution of Gq/11 signaling in AngII-mediated transactivation as measured by the ERK1/2 and the BRET-based readout. Although Gq/11 was absolutely required for ERK1/2 phosphorylation following AngII-stimulation, in contrast, we observed a sustained EGFR-Grb2

  Two-photon microscopy experiments demonstrated that most contacts between GC B and Tfh cells are of short duration (about 2 min), and only about 4% of these contacts lead to the formation of stable conjugates (5 to 60 min) (Allen et al., 2007). Similarly, during extrinsic peptide stimulation, some r

  GPR183 (also known as EBI2) is a Gαi-coupled seven-transmembrane chemotactic receptor. It is highly expressed on follicular B cells, CD4+ dendritic cells (DCs), and CD4+ T cells but is downregulated on germinal center (GC) Amoxapine in secondary lymphoid organs and controls cell migration to achieve

  Most of the data indicating that the six-ankyrin repeat domain-containing Asb genes drive compartment expansion come from zebrafish and concern Asb11. However, there is evidence to suggest that these data can be expanded to the entire vertebrate phylum and to all six-ankyrin repeat domain-containin

  Concerning family A GPCRs, although it has been described that several receptors are able to operate as monomers (Arcemisbéhère et al., 2010; Bayburt et al., 2011; Chabre & le Maire, 2005; Ernst, Gramse, Kolbe, Hofmann, & Heck, 2007; Hanson et al., 2007; Kuszak et al., 2009; Whorton et al., 2007), e

  Over the past decade, targeting DNA repair proteins has emerged as an effective tool to enhance chemosensitivity of malignant cells [9]. However, identification and selection of the proper target of DNA repair pathways is critical to increase cytotoxic activity of chemotherapeutic agents in cancer c

  Importantly, in genetic studies, Saccharomyces cerevisiae Pif1, a member of the SF1 family of helicases, has been implicated in BIR in conjunction with Pol δ (Chung et al., 2010, Saini et al., 2013, Wilson et al., 2013). Using highly purified S. cerevisiae proteins, a system that permits dissection
