  2020-06-03

  

  Another example of negative regulation is the inhibition of the yeast endosome-associated DUB Doa4 by Rfu1 (free ubiquitin chains 1). In a yeast genetics screen, deletion of Rfu1 was serendipitously found to alter global ubiquitin levels [69]. DUBs can regulate these levels by liberating conjugated

• The important role of miRNAs in cellular differentiation

  2020-06-03

  

  The important role of miRNAs in cellular differentiation has been proposed recently. Previous studies had suggested roles for different miRNAs during osteogenesis [20]. Certain miRNAs could promote osteoblast differentiation, such as miR-194 [20], whereas others could inhibit the cell differentiatio

  2020-06-03

  

  Another pathway that requires proper DUB recruitment is the DNA damage response (DDR). After ultraviolet (UV)-induced DNA damage, monoubiquitylated proliferating cell nuclear antigen (PCNA) mediates signaling that leads to repair. The DUB complex USP1/USP1-associated factor 1 (UAF1) deubiquitylates

  Abbreviations Acknowledgements Introduction Dopamine β-hydroxylase (DbH) is the enzyme catalysing the conversion of dopamine to norepinephrine, two important neurotransmitters involved in the central nervous system [1]. This enzyme has been isolated from bovine chromaffin granules as a tetr

  Does a universal mechanism for TLS exist? Our previous studies using the bacteriophage T4 DNA polymerase generated the model provided in Fig. 7 that quantifies the molecular forces influencing key steps in the polymerization pathway during the replication of a non-instructional versus miscoding DNA

  2020-06-03

  

  Expression of MGMT in human Sephin1 can be switched off by enzymatic methylation of a cytosine residue in the MGMT promoter sequence. In this regard, both MGMT and the mismatch repair function MLH1 belong to a subset of DNA repair genes that are subjected to epigenetic control. In consequence, abou

  2020-06-02

  

  Metal ions are known not to be necessary for catalytic activity of serine proteinases. Nevertheless, Co2+ and Ca2+ ions were found to stabilize glutamyl endopeptidase molecule [1], [7], [19]. In our previous study, we have described significant stimulating effect of Ca2+, Mg2+, and Co2+ on biosynthe

  2020-06-02

  

  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),

  2020-06-02

  

  Our previous studies indicate that EBI2 is involved in the regulation of pro-inflammatory responses and inter-cellular communication under pathophysiological conditions such as LPS challenge (Rutkowska et al., 2016b). The data showed that media taken from LPS stimulated astrocytes induces macrophage

  Results and discussion In the present study, we used a set of compounds (Fig. 2) consisting of ATP (a), dATP (b), an ATP analog containing β,γ-nonhydrolyzable hypophosphate P-P bond (c), and three pairs of P-diastereoisomers of α-thio-ATP analogs (d,e,f) containing a sulfur angiotensin receptor b

  The effect of the simple dopaminergic tonic/phasic model on cognitive processing has been investigated by a few studies (Nolan et al., 2004; Rosa et al., 2010). Rosa et al. (2010), using a Stroop task that requires different levels of cognitive flexibility and stability, observed an association betw

  Introduction We have recently identified that caseinkinase 2 (CK2) inhibition protects white matter (WM) from ischemic injury. We focused our research on CK2 because upregulation of CK2 activity is associated with many diseases, including ischemic injury [1,[6], [7], [8]]. This review highlights a

  2020-06-02

  

  EP1, EP3 and EP4 receptor expression on HMVEC-L was shown recently by flow cytometry [14]. However, only EP4 mRNA expression was previously described in these cells [49]. Our data obtained with RT-PCR showed EP4 mRNA and very low levels of EP1 mRNA, but no EP2 and EP3 mRNA expression was detectable

  Results from experiments in model systems have suggested that the DPRs translated from the HRE of C9ORF72 are toxic and play a role in disease pathogenesis (reviewed in Taylor et al. (2016)). Although the DPRs are present in neurons and glia in various regions of the central nervous system (CNS) ear
