  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

  Protein expression and purification. A 3 mL overnight culture of E. coli BL21 (DE3) pLysS pGEX-6P-3-A1S_0222 was grown in Luria-Bertani (LB)-Medium (10 g/L tryptone, 5 g/L yeast extract, 5 g/L NaCl, pH 7.4, 100 μg/mL Amp) at 37 °C and 160 rpm. The overnight culture was diluted 1:100 into 200 mL LB (

  In a recent study, Tomkins et al. [7] analyzed the protein-protein interaction network of ROCO proteins. Based on a database analysis, and only taking into account interactions reported in at least two peer-reviewed papers and/or confirmed by two different methods, 113 interactors were revealed for

  Plants Cp are widely distributed in the plant kingdom and are believed to act as virulence/defense factors for both hosts and pathogens. Cp are also found in plants, animals and bacteria and are known to be virulence factors involved in bacterial pathogenicity [29]. Further, Cp are involved in pepti

  Results and discussion Conclusions An optimization study of the dipeptidyl enoates was performed by chemical structure modifications (Fig. 5). Compound FGA50 displaying R configuration at C-3 was more active than its epimer FGA40. Two modifications of the chemical structure of FGA50 were done:

  As described above, when EGCG was orally administered, CYP3A expression in the liver decreased; however, the CYP3A expression level in the intestine was unchanged (Fig. 3). Although we remain speculative, one reason for this may be that because the level of intestinal bacteria in the upper part of t

  In mouse lung, arsenite enhances the formation of cigarette smoke-induced 8-oxodeoxyguanine (Hays et al., 2006) and BaP-induced DNA adducts (Evans et al., 2004). Moreover, arsenite inhibits the repair of BaP-induced DNA adducts in human lung carcinoma A549 Dp44mT australia (Schwerdtle et al., 2003)

  Introduction Ewing sarcomas/primitive neuroectodermal tumors (ES/PNETs) are relatively infrequent but the second most common sarcoma of the bone next to osteosarcoma. Nearly 80% of them occur in persons younger than 20years. Most of them arise from the bone, but 10 to 20% of them from soft tissue.

  In human neuroblastoma SH-SY5Y CA 074 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 them, in

  EBV Infection Epstein–Barr virus (EBV, human herpesvirus 4) was discovered 50 years ago, when Epstein, Achong, and Barr used electron microscopy to identify viral particles in Burkitt's lymphoma cells. It belongs to the lymphocryptovirus (LCV) genus of the gammaherpesvirus subfamily (Fig. 1A). Th

  Consistent with the known tolerance of the Suzuki–Miyaura reaction to a wide range of aryl substituents, we subsequently found that the commercially available 3-hydroxyphenylboronic Irinotecan pinacol ester () could be coupled to , to give directly and in comparable yield.

  The possibility that a carboxyl group attached to the or position of an -arylaminomethylenemalonate ester would lead to increased selectivity for DHODH has been tested and found not to be the case. Indeed, reduced selectivity compared with the corresponding ester is observed and is attributed to a

  In order to assess quantitatively the contribution of the ung, dug and dut Fmoc-Gln(Trt)-OPfp to uracil-DNA accumulation in E. coli, we have developed a novel method for measuring uracil residues in DNA that is based on the approach of Kow and co-workers [33] for measuring AP-sites in DNA.
