  It has only recently been appreciated that antigen-activated 155 8 undertake two additional transient migrations during the early stages of T-dependent antibody responses. In the first of these, antigen-activated B cells migrate rapidly (within 2–3h) to the outer regions of the follicle before they

  2020-09-28

  

  The β strand domain swap in the UbV.XR dimer appears to be a unique arrangement for a Ub-based dimer. In solution, free Ub has a KD of ∼5 mM for the monomer-dimer equilibrium, and the two subunits in the dimer adopt a range of relative orientations involving residues from Ub’s β sheet (Liu et al., 2

  2020-09-28

  

  It is currently believed that acute morphine administration can impair learning and memory (Friswell et al., 2008). Chronic morphine treatment can also impair access to and retention of spatial memory (Spain and Newsom, 1991, Zheng et al., 2002). Using the Morris water maze experiment, we have previ

  DSBs can be repaired by two major pathways: canonical non-homologous end-joining (c-NHEJ) and homologous recombination (HR) (Chapman et al., 2012). c-NHEJ comprises two sub-pathways, a resection-independent process and a resection-dependent process, and can rejoin break ends with little or no sequen

  Phenotypic responses: alkylation-induced cell death and mutagenesis E. coli alkB mutants were isolated in a screen for strains specifically sensitive to the cytotoxicity of MMS but not UV-irradiation. This was the first indication that the AlkB protein is a primary cellular defence against alkyla

  2020-09-27

  

  This pathway appears to have importance in epilepsy. DGKε(−/−) mice had significantly fewer motor seizure and epileptic events compared with DGKε(+/+) mice [18]. This could be explained by the fact that in the knockout mice a greater fraction of the SAG would be converted to 2-AG. 2-AG itself is kno

  Results Discussion The importance of mitochondria for the initiation and progression of tumorigenesis is now emerging. It is evident that, despite the well-known Warburg effect, tumors have active mitochondrial bioenergetic metabolism (Marin-Valencia et al., 2012, Hensley et al., 2016). Disrup

  In solid tumors, such as those in breast and pancreatic cancer, infiltrating CD68+ or CD163+ tumor-associated macrophages (TAMs) correlate with poor outcome (DeNardo et al., 2011, Kurahara et al., 2011, Shabo et al., 2008). The tumor-promoting function of TAMs is based on their capacity to secrete p

  Haggar et al. reported the synthesis of two new series of 8-(2-imino/oxo/thioxo pyrimidin-4-yl)-4-methyl-6-nitro-2-oxo-2H-chromen-7-yl benzoates 56 (X=O, S, NH) and 8-(pyrazol-3-yl)-4-methyl-6-nitro-2-oxo-2H-chromen-7-yl benzoates 57 [Y=C(O)CH3, 2,4-(NO2)2C6H3]. The 8-acetyl-4-methyl-6-nitro-2-oxo-2

  Partial suppression of the cot-1 (ts) phenotype by deletion of gul-1 has been well documented (Seiler et al., 2006). This is now also very clearly evident in the transcriptional profile of the various strains (Fig. 2). Furthermore, the comparative analysis of the single and double mutants revealed,

  2020-09-27

  

  COMT expression, protein level and activity are down regulated by E2. Using estrogen receptor (ER) positive MCF-7 cells, Xie et al. demonstrated an E2 dose dependent (1, 10 and 100 nM) decrease in S-COMT 1.3 kb mRNA that was maximum after 48 h (Xie et al., 1999). A similar decrease was not observed

  SPR was used to measure biomolecular kinetic interactions between TERRA G-quadruplex and ligand in the present study. SPR is a widely used method, but cannot tell which specific type of interaction happened. Compounds with similar structures probably have similar mechanism of interaction, while comp

  Introduction Hepatocarcinoma is a common and aggressive form of cancer (Trad et al., 2017). Due to a high rate of postoperative recurrence and metastasis, the prognosis for HCC remains dismal (Wang et al., 2017a, 2017b). Subclinical metastasis is the major cause responsible for tumor recurrence and

  The Wnt/β-catenin signaling pathway is a downstream target of SOX9 and is involved in a variety of cellular responses, including cell migration, proliferation, and differentiation [14]. Several studies have identified the Wnt/β-catenin signaling pathway as essential for cartilage function, and it is
