  In this study we generated mice in which the native Bcl6 locus was engineered to produce a form of Bcl6 containing a mutant RD2 domain that disrupts its repressor function. We found that RD2 domain is essential for pre-GC B cell differentiation and clustering into nascent GC within follicles, in par

  Our finding that the ATRX-DAXX-H3.3 complex promotes a form of HR is likely to have important implications for our understanding of the ALT recombination process that takes place at telomeres. We were surprised to observe that ATRX promotes a form of HR, since loss of the ATRX-DAXX-H3.3 complex is

  Verapamil, a calcium channel blocker used clinically as a coronary vasodilator, was amongst the first compounds identified that could reverse MDR and potentiate the effects of MDR1 substrates such as vincristine [15], [16]. Verapamil, along with a number of other MDR1 blockers, have proved largely u

  Materials and methods Results Discussion We confirmed the published cDNA and protein sequence of feline CSF-1R and stably cloned the cat receptor into the Ba/F3 cell line. Activation of feline CSF-1R by recombinant human CSF-1 was previously tested by Woolford et al. [14]. Expression of onc

  The BDNF Val66Met polymorphism is also associated with decreased dendritic arborization and impaired long-term potentiation [25]. This is particularly important for the hippocampus, and healthy individuals with a BDNF Val66Met allele have decreased hippocampal volumes [30]. Hippocampal atrophy is co

  Introduction Breast cancer is the most common malignant tumor in women and the second leading cause of female death [1]. In recent years, with the improvement of early detection and the emergence of new treatment methods, the mortality rate of breast cancer has been greatly reduced. However, the

  A major open question in the field of lipid mediators is the molecular nature of the PLA2 enzyme involved in the release of DHA and related omega-3 fatty acids from phospholipids as a first committed step for the generation of SPMs. Although by analogy with AA it is often assumed that cPLA2α may ser

  Experimental procedures Introduction Perfluorooctane sulfonate (PFOS) is an anthropogenic compound with high thermal, chemical and biological stability, which makes it a perfect ingredient for many industrial applications (Kissa, 2001). Nevertheless, these characteristics also mean that PFOS i

  2020-07-13

  

  The growth inhibitory effect of PGE2 has been linked to the ability of Gs coupled PGE2 receptors EP2 and EP4 to mediate elevation of cAMP [22], [23]. Evidence suggests that this mechanism may not be the key cause of growth inhibition [24]. In various cell types, EP4 receptor has been shown to utiliz

  Many studies have documented that enolase acts as a plasminogen-binding protein and this interaction is involved in the tissue invasion and pathogenicity of the causative agents (Almeida et al., 2004; Avilan et al., 2000; Marcilla et al., 2007; Mundodi et al., 2008; Vanegas et al., 2007).

  EBI2 and its ligand(s) EBI2 was found in a screen of upregulated genes in human B cells upon infection with EBV [1]. EBI2 is a G-protein (Gαi type) coupled receptor [2] but as long as 18 years after its discovery the nature of its ligand remained undisclosed. With the help of transfected cell lines

  While SCF E3 ligase activity was reconstituted with recombinant proteins two decades ago, the ability to probe APC/C was limited until recently because of its behemoth size. Human APC/C is a 1.2-MDa assembly comprised of 19 core subunits (one each of nine different APC subunits, and two each of five

  Aspergillus nigerA. niger is another filamentous fungus, in which alternative dehydrogenases have been described. Filamentous fungi are a very important group of microorganisms that are used in industry (O’Donnell et al. 2011). Biotechnological production processes using these organisms are often hi

  Conclusions The PQQ-dependent CcPDH is the first PQQ-dependent enzyme identified in eukaryotes. The PQQ cofactor binds the enzyme with high affinity, reflected in a Kd of 1.1 nM, and the enzyme oxidizes 2KG, l-fucose, and rare sugars such as d-arabinose and l-galactose.
