Insights into the control of geminiviral promoters.

abstract：:Prostaglandin E₂ (PGE₂) is an arachidonic acid (AA)-derived signaling molecule that can influence host immune responses to infection or vaccination. In this study, we investigated PGE₂ production in vitro by cells infected with the poxvirus vaccine strain, modified vaccinia Ankara virus (MVA). Human THP-1 cells, murin...

abstract：:The 5' leader region of the HIV-1 RNA contains the major 5' splice site (ss) that is used in the production of all spliced viral RNAs. This splice-donor (SD) region can fold a stem-loop structure. We demonstrate that whereas stabilization of this SD hairpin reduces splicing efficiency, destabilization increases splici...
