Báo cáo khoa học: The transcriptome of the colonial marine hydroid Hydractinia echinata ppt

... most of its members are colonial and marine. Therefore, we analy- sed the transcriptome of a more typical member of this class, the colonial marine hydroid Hydractinia echinata. This animal offers ... easy access and handling of the existing Hydractinia data. Results Generation of the Hydractinia echinata ESTs To generate a representative EST dataset of...

... [26]. These findings lead to the hypothesis that Fe-bound ApeSOD mimics the product-inhibited form and the shift of Tyr39 sup- presses the release of the peroxide product. This may be one of the ... inhibi- tion of the binding of the superoxide substrate and the other to product inhibition by hydrogen peroxide. There are two mechanisms proposed for the reaction cy...

... that the activation of IRF-3 by M-pIC treatment is mediated by the TLR3 ⁄ TRIF signaling pathway. We obtained further evidence by examining the status of the phos- phorylation and dimerization of ... cells. First, we confirmed the effect of NS3-4A on the activation of the IFN-b gene promoter by the Cardif exogenously expressed in PH5CH8 cells. The results of the...
