Understanding the regulation mechanism of radiation sensitivity is still a research hotspot. Increased sensitivity to ionizing radiati

  Introduction Coping with DNA damage is possible thanks to surveillance mechanisms (checkpoints), that detect the problem and promote its solution [1], [2], and to repair and tolerance pathways that remove the lesions or reduce the damage consequences [3], [4]. Failures in these processes have a h

  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

  The interaction of EPAC2 with Rim1 has an important role in regulating neurotransmitter release. In addition, a recent EPAC2 knockout mice model study provides evidence that EPAC2 promotes transmitter release by maintaining the readily releasable pool (RRP) at mossy fiber (MF) synapses in the hippo

  Results Discussion Many studies have shown that intrinsic properties of the E2 enzyme govern the nature of the Ub modification, including both the multiplicity of the Ub modification and the specific Nalidixic acid type in the case of polyubiquitin chains [3], [4], [9], [14]. Whereas previous

  Everolimus treatment showed an increase in the number of plaques and a reduction in plaque size, depending on concentration and treatment time (Fig. 1, Fig. 2). Everolimus-pretreated Reutericyclin mg adsorbed less virus with more plaque formation in the initial phase of infection (Fig. 3). The abil

  In order to validate the ATP competitive mode of inhibition, compound 12 was selected as a representative inhibitor of this series, and the IC50 values were determined at eight different concentrations of compound 12 ranging from 0.001 to 100 μM, and repeated four times using different ATP concentra

  Based on the above, we hypothesized that a PROTAC strategy would be effective to induce CK2 protein degradation. Herein reported is an approach for the preparation of novel PROTACs via “click reaction” for degradation of CK2 protein (Fig. 2). Importantly, “click reaction” is a very facile, selective

  Recently, pharmacological studies have revealed that natural compounds achieve increasing attention due to its high therapeutic effectiveness and low adverse effect, compared with the chemically synthesized compounds. Emodin is a kind of natural anthraquinone derivative enriched in traditional Chine

  Estrogen receptors (ERs) belong to the third class of nuclear receptors (NR3) [23]. Two different forms of ER have been described, ERα and ERβ. They are coded by two distinct genes (ESR1 and ESR2, respectively) containing 8 transcribed exons that give rise to six conserved protein domains: domains A

  Introduction Protein modification by ubiquitin and ubiquitin-like proteins is one of the most common and important regulatory mechanisms in biology (Finley et al., 2004, Pickart, 2004). Ubiquitination is carried out by an enzymatic cascade consisting of three steps. In the first step, ubiquitin i

  Our results demonstrate that 17-pt-PGE2 - in addition to its described effects on EP1 and EP3 receptors - also acts as an EP4 agonist and thereby enhances vascular barrier function. Materials and methods Results Discussion In this study we demonstrate that the purported EP1/EP3 receptor ag

  Some family I DNA ligases can use dATP as nucleotide cofactor. For instance, human 4-Aminobutyric acid receptor I uses dATP with a catalytic efficiency that is only 36-fold lower in comparison to ATP [9]. EhDNAlig is unable to use dATP as a nucleotide cofactor, indicating a more constrained active
