  2021-02-08

  

  Two nutrient-sensing pathways, the cAMP-protein kinase A (PKA) pathway and the target of rapamycin complex 1 (TORC1) pathway, are implicated in Msn2/4 regulation. Under non-stress conditions, Msn2 localizes in the cytoplasm and is inactivated by both PKA-dependent phosphorylation of the nuclear loca

  Acknowledgements Introduction α-L-Rhamnosidases (EC 3.2.1.40) are glycosyl hydrolases (GHs) that cleave terminal α-l-rhamnose from a large number of natural products [1]. The action of α-L-rhamnosidases (α-RHAs) has been reported, among others, on different complex substrates such as heteropol

  2021-02-08

  

  The assembly and maturation of invadopodia can be initiated by chemical stimuli such as the epidermal growth factor (EGF), as well as the mechanical signals from extracellular matrix (ECM). Upon binding, EGF activates the EGF receptor (EGFR), which further activates several intracellular signaling p

  Herbal products may alter the metabolism of certain drugs and, likewise, the metabolism of components of herbal products may be altered by some drugs, specifically those that affect cytochrome P450 ApoBrdU DNA Fragmentation Assay Kit (CYP). These can bring about an alteration of the pharmacokinetics

  The expression of EBI2 has been found to be dysregulated in several types of B cell malignancies and is thus reduced in e.g. diffuse large B-cell lymphomas [12] and chronic lymphocytic leukemia [13] and increased in post-transplantation lymphoproliferative disorders (PTLDs) [14]. EBI2 is also highly

  2021-02-08

  

  All known vertebrate TRIMs are categorized in 11 distinct subclasses depending on the types of domains present at their carboxyl-terminals (Fig. 3) [29], [35]. Beyond conserved N-terminal domains, it is the C-terminal that provides specificity of interactions with other proteins. The subclass IV for

  Materials and methods Results Discussion Ubiquitination is an important eukaryotic process that defines the fate of proteins and their functionality. It has multiple roles in cell survival, differentiation and development (Glickman and Ciechanover, 2002). Ubiquitination is usually known as

  The molecular mechanism by which CRM1 regulates IEC apoptosis in CD remains to be explored. As an inhibitor of cyclin E-Cdk2, p27kip1 plays a pivotal role in controlling cell proliferation, S phase entry, and G1 phase exit during development and tumorigenesis [38]. As previously reported, p27kip1 is

  Since the aggregation of neurotoxic forms of Aβ plays a pivotal role in AD pathogenesis, an approach that using small molecules to bind Aβ monomers and prevent their assembly into cytotoxic oligomers attracts great interest for the development of AD drugs. Therefore, the potential inhibitory activit

  Our data demonstrate that MPO increased ETRB mRNA expression, which translated into an increase in ETRB protein expression, which proved to be dependent on the enzyme's catalytic activity. Of importance, addition of MPO was sufficient to increase ETRB expression, revealing that endogenous (endotheli

  More unusual modifications also regulate DUBs. Recent reports have illustrated how reactive oxygen species (ROS) can regulate DUB activity 87, 88, 89, 90. ROS can serve as potent signaling molecules by reacting with active site cysteines of tyrosine phosphatases and some cysteine peptidases to form

  Although PQQ has nutritional importance and pharmacological effects in higher organisms, including humans [15], until recently, there was no clear evidence for the use of PQQ as a co-factor in a eukaryotic enzyme. This review presents a novel eukaryotic PQQ-dependent quinohemoprotein recently discov

  Our previous studies have demonstrated that the DDR2 discoidin domain fully contains the binding site(s) for the fibrillar collagens I and II (Leitinger, 2003, Leitinger et al., 2004). The binding site for collagen I was mapped to three spatially adjacent surface loops within the DDR2 discoidin doma
