  We also show that in both ATM proficient and deficient/mutant p m x the activation of ATR signaling is DSB complexity-dependent (Figs. 1, 4A, C and E, 6A and B). Wang et al. have also reported that the effects of ATR and CHK1 on radiosensitivity are independent of the NHEJ repair pathway [41], [42].

• A third motif involves the toggle switch

  2023-08-14

  

  A third motif involves the toggle switch and consists of the conserved FxxCWxP sequence in TM6 of class A GPCRs (Hofmann et al., 2009, Rosenbaum et al., 2009). Rotamerization of Trp in combination with a kink caused by Pro facilitates the outward movement of TM6 upon activation (Hofmann et al., 2009

  2023-08-14

  

  The growth of cancer can control by inhibiting the rate of cell proliferation or increasing the rate of selective apoptosis and effectiveness of anticancer agents varies according to genetic constitution of cancer. Hence, we investigated the anticancer activity of arginase against different kinds of

• Mitochondrial dysfunction resulting from mtDNA abnormalities

  2023-08-14

  

  Mitochondrial dysfunction resulting from mtDNA abnormalities may trigger retrograde signaling pathways from the mitochondrion to the nucleus, which regulate the expression of genes involved in diverse cellular processes, including metabolism, stress responses, tumor progression, nutrient sensing, li

• Once apoptosis has been initiated the HMGA proteins

  2023-08-14

  

  Once apoptosis has been initiated the HMGA proteins themselves undergo marked changes in both the types and extent of their post-translational modifications (PTMs; review in [149,175]), some of which are likely correlated with alterations in chromatin structure. For example, the early stages of apop

  2023-08-14

  

  We made a number of choices in the original design of our experiments. First, we used only portions of the 5′ and 3′ regulatory elements from S. cerevisiae. The sequences of these regions were known [32] and our goal was to express the Pf-DHFR at low levels. In fact, our choice of only 600 bp of the

• The fluorescence in a fluorescent antibiotic

  2023-08-14

  

  The fluorescence in a fluorescent antibiotic can be derived either from functional groups with intrinsic fluorescence in an existing antibiotic, or via synthetic conjugation of a fluorophore to an antibiotic core to enable visualisation. Attachment of fluorophore to an antibiotic should ideally not

• Pregnane X receptor PXR is a nuclear receptor

  2023-08-14

  

  Pregnane X receptor (PXR) is a nuclear receptor that plays an important role in regulation of metabolism and disposition of structurally diverse xenobiotics as well as endogenous steroids and bile acids (Bertilsson et al., 1998, Kliewer et al., 1998, Lehmann et al., 1998). PXR regulates the metabol

  There is a growing literature on ABCA2 expression in human biopsies, where it has been described as a potential biomarker of leukemias. In childhood T-cell acute lymphoblastic leukemia, ABCA2 and ABCA3 were expressed at high levels, which upon treatment with methotrexate, vinblastine and doxorubicin

  2023-08-14

  

  In the vasculature, it is known that A2A and A2B adenosine receptors are stimulatory for adenylyl-cyclase, leading to cyclic-AMP (cAMP) production and vasodilation, while the A1 and A3 adenosine receptors are linked to the inhibitory Gi, suppressing adenylyl-cyclase and favoring contraction. However

  As noted earlier, the PfkB family of carbohydrate kinases can phosphorylate the hydroxymethyl group of a wide variety of sugar moieties [1], [3]. Recent searches of the Swiss-Prot database with the two conserved sequence motifs found in these proteins (Accession nos. PS00583 and PS00584) identified

  The small fishers with little or no quota who remained relied on quota leasing arrangements to continue their fishing operations. Such arrangements had relatively high transaction costs and by early 2000 it appeared that the demise of the small fisher was imminent [2]. The introduction in 2001 of t

  Macrophage polarization is linked to activation of the ligand-dependent transcription factor PPARγ. Recently, Odegaard et al. demonstrated with a macrophage-specific deletion of PPARγ in mice that alternative macrophage activation is impaired [14]. We provided evidence that contact to apoptotic pp3
