  2020-05-14

  

  The combination of brequinar and 5-fluorouracil (5-FU) has been evaluated to assess whether brequinar-induced uridine depletion would improve 5-FU activity. In cells, 5-FU is metabolized into FdUMP and inhibits thymidylate synthetase, which catalyzes the formation of thymidine monophosphate from deo

  2020-05-13

  

  Liver metabolic programming begins in utero. Aiming to find a reason for the decreased lipid catabolism enzyme expression observed in fetuses and offspring from SFD rats, we studied the effect of leptin on liver catabolism in fetuses from control and SFD rats. Livers from control fetuses responded t

  2020-05-13

  

  Synthetic progestogens (also known as ‘synthetic gestagens’, ‘synthetic progestins’ or simply ‘progestins’) are designed to mimic the effects of progesterone (P4) and are the active pharmaceutical ingredient in many contraceptives and hormone replacement therapies. Since most progestins are derived

  Coactivator Binding Sets APC/C Catalytic Core in Motion A coactivator not only recruits substrates to APC/C [18] (Figure 3B), but also stimulates repositioning of the catalytic core 19, 24. High-resolution cryo-EM maps of apo forms of APC/C without a coactivator show the catalytic core and platfo

  Results To understand how Rad53 functions to maintain replisome integrity, we first analyzed newly synthesized leading- and lagging-strand DNA in wild-type (WT) and rad53-1 mutant cells using BrdU-IP-ssSeq, a method that detects synthesis of both leading and lagging strands (Yu et al., 2014). Bri

• Most enzymes involved in the addition

  2020-05-13

  

  Most CORM-3 involved in the addition and removal of ubiquitin bind weakly to an overlapping surface on ubiquitin. Previously, Sidhu and colleagues diversified this surface and then used phage display to screen these libraries of ubiquitin variants (UbVs) for binding to DUBs and E3 ligases (Ernst et

  2020-05-13

  

  As the primary model we selected LDL-receptor knockout mice because these resemble the human plasma lipoprotein profile more closely. Currently, genetic models with reduced milk cholesterol content, which mimic cholesterol-free formula feeding, are unavailable. Thus, instead of modifying milk choles

  2020-05-13

  

  An additional difference in ACC-1 between H. contortus and C. elegans is the results from the oocyte expression experiments. Here we found that unlike Cel-ACC-1 that was reported to form a functional homomeric channel (Putrenko et al., 2005), Hco-ACC-1 does not. However, we have observed that in gen

  2020-05-13

  

  In principle, in vitro techniques for assessing enzyme induction might include the use of cultured hepatocytes, precision-cut liver slices, immortalized LY 303511 lines (such as those derived from hepatomas) and reporter gene constructs (where appropriate cells are transfected with recombinant DNA

• The DDR mediated lysyl oxidase induction in osteoblasts

  2020-05-13

  

  The DDR2-mediated lysyl oxidase induction in osteoblasts reported here is a novel function for this receptor. Various functions have been reported for DDR2. In an in-vitro study, Zhang and colleagues showed that DDR2 activation leads to Runx2 phosphorylation, which regulates osteoblast differentiati

  2020-05-12

  

  CXCR5 is not only critical in the B cell lineage in FL. A high proportion of CXCR5-expressing follicular helper T cells (TFH) were observed in FL but not in closely related DLBCL [141] and further investigation revealed that FL regulatory T cells (Tregs) used a CXCL13-CXCR5 autocrine loop for positi

  Although our knowledge of the biochemical and biological functions of E3 ubiquitin ligases has increased in B-cell malignancies, a deeper characterization of cell-context dependent substrate regulation and biological relevance is needed. The recent approval of a general proteasome inhibitor, VELCADE

  2020-05-12

  

  Mulan is one of three E3 ubiquitin ligases that are present in the mitochondria along with MARCH5/MITOL (membrane associated RING-CH5) and RNF185 [14], [15], [16], [17]. Mulan is a 352-residue polypeptide that crosses the mitochondrial outer membrane (OMM) twice, its amino-terminus, which includes t

  2020-05-12

  

  Ubiquitination is a covalent attachment of 76 amino Dryocrassin ABBA ubiquitin molecules to target proteins, either as single moieties (mono-ubiquitination) or as poly-ubiquitin chains of different structures, formed through isopeptide bonds between specific lysines of one ubiquitin residue (for exa

  Substituents at the C11 position — An oxygen-containing substituent at the C11 position also affects the catalytic activity of Δ1-KSTDs. The Δ1-KSTDs from the Gram-positive bacteria R. equi [29], N. simplex ATCC 6946 and IFO 12069 [48,49,52], and R. rhodochrous IFO 3338 [27] were able to 1(2)-dehydr
