And H4 acetylation patterns across the DES locus and surrounding 500 kb region, we next sought to obtain a more detailed map of epigenetic status specifically across the DES LCR, as this constitutes a crucial regulatory element. Chromatin used for the microarray analysis was analysed by Q-PCR to assess enrichment for selected regions within DES and the DES LCR.The ENCODE region ENr331 which spans

Streptococcal plasminogen activator, triggers the activation of the human contact system. Activation of contact system factors at the surface of the Streptococcus pyogenes serotype M49 is dependent on streptokinase and plasminogen. Our results also show that secreted streptokinase is an efficient contact system activator, independent from a contact surface. This results in the processing of high-m

N of the mAb were shown to be able to discriminate a thermally degraded sample (data not shown), demonstrating that the utilized assays are sensitive to detect differences in activity, if they did exist. It is well established that IgG1 mAbs are efficient mediators of effector function, and are able to bind to many of the known FccRs. A sensitive comparison of these Fcdependent activities is impor

Nhibitor TSA on the mRNA expression of MAGE-A1 gene and the other family members (MAGE-A2, -A3 and -A12) in different cell lines. Moreover, we assessed the methylation status of the MAGE-A promoters by sodium bisulfite mappingbefore and after stimulation with the demethylating agent 5-aza-CdR and/or TSA. While the methylation patterns clearly correlated with the basal MAGE RNA transcript levels, u

Oteobacteria). The evolutionary history deduced here based on signature sequences in some of the most highly conserved protein sequences in the biota is in contrast to the rather confusing picture that seems to be emerging from other analyses of the completed bacterial genomes (21, 50, 68, 130, 143, 144, 182, 191, 255). However, as has been pointed out (50, 143, 144, 182), of the large number of s
