  Importantly, in genetic studies, Saccharomyces cerevisiae Pif1, a member of the SF1 family of helicases, has been implicated in BIR in conjunction with Pol δ (Chung et al., 2010, Saini et al., 2013, Wilson et al., 2013). Using highly purified S. cerevisiae proteins, a system that permits dissection

  The unique property of mutant IDH1/2 in producing an oncometabolite that has no known physiological function makes mutant IDH enzymes as obvious potential therapeutic targets for the treatment of IDH-mutated tumors (Rohle et al., 2013, Wang et al., 2013). Clinical studies have also suggested the pre

  2021-07-15

  

  Predictions of enzyme topology for DGAT2 are more difficult since the DGAT2 polypeptide sequences are more diverse across species than those of DGAT1. The length and function of the hydrophilic N-terminus preceding the first hydrophobic segment varies with species – for example, segments in fungi ar

  Several single nucleotide polymorphisms (SNPs) in humans affect CYP3A expression and activity (Lamba et al., 2002). The CYP3A4 SNP rs2740574 (also referred to as CYP3A4*1B, by The Human Cytochrome P450 (CYP) Allele Nomenclature Database, http://www.cypalleles.ki.se/) is a change in the promoter regi

  In the present study, cells were exposed to a low level of arsenite and a low cytotoxic concentration of BaP. Thus, γ-H2AX loss correlated with repair of DNA damage in cells co-exposed to arsenite and BaP. These results show that arsenite inhibits repair of BaP-induced DNA damage. In a previous stu

  Acknowledgements Introduction Ischemic retinopathy is common to the major causes of blindness, including proliferative diabetic retinopathy, venous occlusion, and retinopathy of prematurity. The hypoxia that follows retinal capillary obliteration drives deregulated growth of new blood vessels

  2021-07-14

  

  Mammalian cells contain significant amounts of a relatively lesser known enzyme that shows marked specifity for ether lipids containing AA and other 20–22 carbon fatty acids. This enzyme is called CoA-independent transacylase (CoA-IT), and transfers polyunsaturated moieties of 20–22 carbons, typical

  Previously, we showed that MS-10, a combined extract of Cirsium japonicum var. Maackii (Maxim.) Matsum. (Korean milk thistle) and Thymus vulgaris L., increases the efficiency of estrogen in the estrogen-deficient state by activating the estrogen receptor (ER). MS-10 increased bone mineral density (B

  2021-07-14

  

  HCV has evolved mechanisms to evade humoral immune responses including high functional flexibility and variability of immunogenic portions of its envelope proteins. The highest sequence variability occurs in the first 27 am 580 of the N-terminus of E2, which is referred to as the hypervariable regi

  The expression of cytokine-inducible genes is mediated by a number of components within the cell. It has been shown that Jak2 and the Ras/Raf/MAP kinase signaling cascades are required for the expression of DUB-1[9], [29]. However, the enhancer domain of DUB-1 lacks a consensus sequence for Stat bin

  Conclusion The results of the current study show that boldness is associated with higher gene expression of drd2a, drd2b and oprd1b in zebrafish males. The results are correlational and additional experiments are needed to clarify the causal role of these receptors in zebrafish behavior. Confl

  2021-07-13

  

  P4H is a nonheme iron(II) dioxygenase that uses O2 and α-ketoglutarate as co-substrates (Fig. 1A). The three-dimensional structure of mammalian P4H is unknown. We reasoned that an electrophilic analog of α-ketoglutarate could serve as an irreversible inhibitor of the enzyme and, hence, a useful prob

  In the present study, we have examined, an alternative approach for introduction of Hyp into bacterial, non-animal collagens. Previously, Gruskin and colleagues [27] had shown that Hyp could be introduced into recombinant mammalian collagen sequences in E. coli through a mechanism of co-translationa

  However, not all inhibitory profiles by metals can be a priori considered artifacts of the methodology used to quantify the activity of such enzymes. Metals can indeed interfere with cholinesterases, and the mechanisms are varied. The inhibitory effect of specific metals may derive from their abilit

  Soon after the discovery of ET1 and the cloning of its ETA and ETB receptors, low-molecular-weight compounds were identified that can prevent the binding and effects of radioactively labeled ET1 3, 5, 6, 8. Initially, these ERAs resulted from screening efforts (e.g. BQ123 39, 49 and bosentan [50]).
