  2021-04-20

  

  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. An

  It has been reported that Eph/Ephrin are involved in the regulation of the tumor angiogenesis [10], [11], [12]. The distinct and specific involvement of cyclic amp function and veins in tumor angiogenesis is unclear. EphrinB2 is expressed in arteries and its receptor EphB4 is expressed in veins; th

  Mass spectrometry-based technologies Oxysterols tend not to be observed in global lipidomic analysis, whether shot-gun based electrospray ionisation – mass spectrometry (ESI-MS) or liquid chromatography (LC)-MS based. This is because of their comparatively low-abundance and poor ionisation charac

  In the SUMOylation pathway, SCE1 as an E2 enzyme has an important role in mediating the conjugation of SUMO to target proteins. The accumulated SUMO conjugates in plants are associated with abiotic stress responses (Castro et al, 2012). We performed a drought stress analysis on WT plants, induced by

  2021-04-20

  

  Many DNA repair pathways are candidates for DPC repair. Nucleotide excision repair (NER) is widely involved in both bacteria and eukaryotes in removing cross-linked protein with low molecular weights (11kDa) (Ide et al., 2011). The predominant pathway chosen by Pirarubicin may also depend on the ty

  Given the structural similarity of BMAA to other amino acids, our hypothesis was that N-nitrosation of BMAA might result in a toxic alkylating agent, providing a previously unrecognised mechanism for BMAA action. Materials and methods Results and discussion We first examined whether chemical

  2021-04-19

  

  One of the therapeutic proteins used in cancer therapy is glucarpidase, also known as Carboxypeptidase G2, CPG2, which originates from the bacterium Variovorax paradoxus (old name, Pseudomonas sp. strain RS-16). It has no mammalian equivalent (Thompson et al., 1994; Kamlage, 1994) and is a zinc-depe

  Tacrine (9-amino-1,2,3,4-tetrahydroacridine) (I, Fig. 1) was the first AChEI to be approved by the Food and Drug Administration (FDA) for the treatment of AD [25], [26], [27], [28]. However, despite its good AChE inhibitory activity, tacrine was far from ideal due to its low bioavailability and shor

  Introduction The cys-loop ligand gated ion channels (LGICs) are membrane-bound proteins mediating fast transduction from chemical to electrical signals at neuronal synapses and neuromuscular junctions [1], [2]. Each subunit that makes up the pentameric LGIC architecture possesses a dicysteine bri

  In recent years, there has been much interest within the endothelin community regarding the possibility that ETA and ETB receptors may form homo- and heterodimers. Heterodimerization of endothelin receptors may provide an explanation for the results mentioned in the previous paragraph and might also

  Among RAS mutant tumors analyzed, we found that the efficacy of either the SHP2 inhibitor SHP099, or combined MEK and SHP2 inhibition was best in those expressing RAS mutations at G12 (Figure 7B). Recent studies revealed that cellular RAS(G12C) activity depends on RTK-mediated nucleotide exchange, a

  In human neuroblastoma SH-SY5Y p2x receptors and in lymphoma Jurkat cells, Yamanaka et al. [56] showed that exogenously added 24(S)-hydroxycholesterol could be efficiently esterified by ACAT1. These results suggest that both ACAT1 and ACAT2 can control the oxysterol levels by directly esterifying th

  The elastase-induced injury model has been shown to produce airspace enlargement, and increases in lung volume and compliance that are similar to those observed in human patients (Hantos et al., 2008, Hamakawa et al., 2011). Thus, this model, which has been used to study emphysema, should be adequat
