  Future advances in the in vivo molecular imaging of enzyme activity will greatly benefit from the progress towards the quantitative detection of enzymes. Quantitative imaging requires knowledge of both the location and concentration of a specific enzyme, which is dependent on the simultaneous measur

  2020-01-06

  

  The activity of cysteine endopeptidases involved in the germination of caryopses is generally regulated at two levels: the hormonal induction of synthesis by gibberellins (Drzymała et al., 2008) and a putative regulation of activity by phytocystatines (Kiyosaki et al., 2007, Martinez et al., 2009),

  2020-01-06

  

  Results Discussion PKR is activated by viral dsRNA and exerts its antiviral effect through phosphorylation of eIF2a. Because eIF2a phosphorylation leads to attenuation of protein synthesis, many viruses have evolved mechanisms to block or suppress PKR activation. Some viruses use alternative t

  2020-01-06

  

  Errors are detected by comparing the output data against an error free reference. After error detection, the process is restarted so that only one error is accounted. The susceptibility is inferred by the ratio between injected events and detected errors: = 100×errors÷events%. Error rates are obtai

  In the present study we investigated the effect of morphine withdrawal on G-protein coupling to opioid and ET receptors in neonatal rats. Morphine-induced G-protein activation was significantly higher in neonatal rats undergoing morphine withdrawal; suggesting enhanced coupling of the receptors to G

  Although many of the genetic changes remain to be elucidated, there is evidence to support a difference in incidence and rate of rupture of cerebral aneurysms between men and women, and between pre- and postmenopausal women, suggesting that aneurysm formation may be affected by hormonal changes.18,

  Lymphoplasmacytic lymphoma/Waldenstrom macroglobulinemia Lymphoplasmacytic lymphoma (LPL) and its subgroup Waldenstrom macroglobulinemia (WM) are rare and indolent lymphomas that arise from fully differentiated B cells. The only family of GPCRs that has been well studied in LPL/WM is the chemokin

  Increasing evidence supports that the B-cell lymphoid malignancies develop from various stages of B-cells, hijacking the mechanisms that drive B-cell differentiation and activation [27]. For instance, mantle cell lymphoma (MCL) and chronic lymphocytic leukemia (CLL) originate from the pre-germinal c

  2020-01-06

  

  The fact that the mean tumor size of the E1202-654 + α-GalCer group was much smaller than that of the α-GalCer inoculated group in both protocols indicates that immunization with E1202-654 plus α-GalCer, which induces a strong CD8+ T cell E1 antigen-specific immune response, is involved in the elimi

  An ideal CHK-1 inhibitor would be minimally cytotoxic, while enhancing the anti-tumor effect of a real cytotoxic agent that would be used in combination with the inhibitor. Our CHK-1 inhibitors have shown excellent selectivity over a panel of kinases including those regulating the cell cycle, but th

  From an industrial perspective, the low turnover numbers and limited substrate scope of α-KG halogenases still represents a significant challenge. However, in light of the fact that currently no chemical processes are available for the selective halogenation of aliphatic carbon centers in complex mo

  2020-01-06

  

  We first confirmed LPS-induction of markers known to induce NF-κB signaling in Caco2BB cells, as established for numerous other cell types [31]. We initially selected this approach to monitor NF-κB activation instead of directly monitoring p65 as it is technically straightforward and provides both u

  DNA damage represents a persistent threat to genomic stability. A critical link exists between DNA mutation, chromosomal rearrangement and cancer development. In myeloid malignancies, various chromosomal translocations and/or mutations increased cellular reactive oxygen species (ROS), followed by DS

  In addition to demonstrating the importance of DNMTs, we show that TGFβ1 differentially regulated DNMTs, and that TGFβ1 is both necessary and sufficient to induce lineage conversion of hepatocytes into MLCs with phenotypes and multipotency resembling MSCs. Upon withdrawal of TGFβ1 on day 28, we obse

  One step in pyrimidine biosynthesis is conversion of l-dihydroorotate (DHO) to orotate (ORO), under action of the enzyme dihydroorotate dehydrogenase (DHODH, EC 1.3.99.11), which contains a flavine (FMN) as redox cofactor [1]. In this transformation, electrons resulting from DHO oxidation are transf
