  2019-10-17

  

  DNA replication checkpoint kinases in both yeast and human Leupeptin pathway upregulate dNTP levels under replication stress to mediate their essential function at replication forks (Yeeles et al., 2013). It is possible that upregulation of dNTP levels under replication stress helps fork restart on

  2019-10-17

  

  In this study, using REMD with the crystal environment, we investigate the effect of cryo-cooling on the crystal structure of Escherichia coli DHFR. DHFR is an important model enzyme (for review, see, e.g., (30)), and has been studied for decades (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43).

  2019-10-17

  

  Pathological changes in animal are powerful indicators of the exposure to environmental stressors. The liver serves as an appropriate organ for the study of pollutant effects because of its high capacity to accumulate pollutant and its susceptibility to histopathological damage by pollutants (Padmin

  2019-10-17

  

  Assessment of the activity of native and denatured TAT-CPG2 after penetration suggests that TAT-CPG2 has been successfully delivered into the cells, and the transduced enzyme is functional inside the cells. The enzyme activity of both native and denatured TAT-fusion proteins in the cultured HepG2 nh

  Conclusion In this study, we have shown the construction, expression and purification of CPG2 fused to the HIV-1 TAT peptide (TAT–CPG2). We have demonstrated for the first time that TAT-CPG2 in both native and denatured forms could be efficiently transduced into the HepG2 cells. Also, we have pro

  Introduction Breast cancer is a highly prevalent malignancy. There are some recognized risk factors for breast cancer, like early menarche or late menopause, which increase the length of the exposure to hormones, as a result of a higher number of ovarian cycles [1]. Moreover, there is evidence supp

  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

  Conclusions and future directions In recent years we saw major advances in our knowledge of H2A-DUB biology, with discovery of novel mammalian H2A-DUBs, better understanding of their biochemical properties, and development of several animal models to address their in vivo functions. However at pr

  Given the fact that most criticism on genetic association studies is the lack of replicability (Hirschhorn, Lohmueller, Byrne, & Hirschhorn, 2002), the aim of the present study is to investigate the influence of the DBH polymorphism rs1611115 (C-970T) on RD in two independent samples of healthy part

  Introduction Structure of the Ku heterodimer associated to DNA The atomic structure of the Ku heterodimer, alone and bound to a small DNA fragment, was recently determined (Walker et al., 2001) and has significantly improved our understanding of DNA recognition by DNA-PK holoenzyme (Fig. 3). B

  2019-10-16

  

  The occurrence of three Ag-NORs per metaphase and/or a maximum of three nucleoli per nucleus in most of the varieties may be explained by chromosomal rearrangements or unequal crossing-over events that induce the deletion of the fourth active rDNA loci. Also, the chromosome pair that showed less int

  The knockout mice models of the DNMTs gene shed light on understanding the molecular background of male infertility development. Dnmt1−/− causes demethylation of the genome (Lei et al, 1996, Li et al, 1992) (). The Dnmt3a conditional knockout mouse models exhibit spermatogenic arrest at the spermato

  Even though Et743 modification of DNA delayed the progress of the translocating enzyme significantly, it did not trap RecBCD on DNA, nor did it alter the activity of the enzyme significantly. Under catalytic conditions, no loss of enzyme activity was observed (Table 2), nor were stable unwinding int

  Previous synthetic lethal screening efforts (Cox et al., 2014) have mainly used RNAi as a means of identifying potential targets (Barbie et al., 2009, Kim et al., 2016, Luo et al., 2009, Scholl et al., 2009), although a few screens (Shaw et al., 2011, Steckel et al., 2012) have been performed with
