  In mammals, ribonucleotide reductase (RNR) is a unique enzyme that catalyzes the rate-limiting step of de novo synthesis of deoxyribonucleoside triphosphates (dNTPs).7, 8 Mammalian RNR consists of two homodimer subunits: the large catalytic dimer RRM1 and the small regulatory dimer RRM2 or RRM2B.

  It is noteworthy that little is known as to the role of autophagy in regulation of eNOS phosphorylation and eNOS uncoupling. eNOS monomers, but not eNOS dimers could be degraded by ubiquitination [39], harbingering the existence of protein degradation pathways in modulation of eNOS turnover and acti

  As with all meta-analysis, this study certainly has some limitations. First, our results were derived from unadjusted analyses due to lack of raw data, and lack of further adjusted analyses for age, gender and co-morbidity conditions may impact the reliability of our findings [63]. Second, obvious h

  Protein acetylation Several reports show that MTX is able to induce acetylation of histones and other proteins. Extensive studies have established that histone acetylation is primarily associated with gene activation. Acetylation occurs at lysine residues on the amino-terminal tail of the protein

  To determine direct DDR1-binding partners and to further connect to Akt and mTOR signaling, we performed mass spectrometry on DDR1 immunoprecipitates and found various candidates of the Akt and mTOR pathway such as LARP1 (La-related protein 1) and RPS6 (40S ribosomal protein S6/ S6). Most intriguing

  Proteolysis by CPs is crucially important for cereal seed development and germination. However, these enzymes must be tightly controlled. Pre-harvest sprouting is a phenomenon in which the control of CPs is disrupted. This disruption manifests in the premature synthesis and activation of CPs, leadin

  While several C-terminal peptides have been reported to have modest (astressin) or substantial (astressin2-B, antisauvagine-30) subtype selectivity for the CRF2 receptor (), [125I]YP20 is the first reported small analog of the C-terminus of CRF exhibiting subtype selectivity for the CRF1 receptor vs

  What does this mean for cancer therapy? We found that components of the de novo pyrimidine synthesis pathway rarely mutate in cancer, clearly showing its importance. In our experimental models, the pathway, including DHODH itself, was primed to respond when the block in CoQ redox-cycling was removed

  In a study on the time course of a mechanism-based inactivation of CYP3A by HIV protease inhibitors, Katzenmaier et al. [37] reported that the suppression of CYP3A activity continued for threedays after the discontinuation of ritonavir. In the present study, the CYP3A activity on day 28 after a seve

  DDX3 belongs to the DEAD-box family of proteins, ATP-dependent RNA helicases characterized by the presence of a highly conserved helicase core domain [13]. This catalytic core is composed of two RecA-like domains containing motifs involved in ATP binding/hydrolysis, RNA binding and helicase activity

  It should be noted that the long-lifetime binding-responsive luminescence of ARC-1528 and ARC-1530 becomes evident only upon illumination with radiation at near-UV range where the excitation of ATB or ASB moiety is possible. At higher wavelength range (visible light), the fluorophore (5-TAMRA) can b

  Replacement of the saturated -propoxy group in compound with the unsaturated allyloxy group to obtain compound resulted in 10-fold decrease in ET receptor antagonism and more than 20-fold decrease in ET-selectivity. Analogous unsaturated allyloxy compound in the tetrazole series was found to have di
