20090203055 | Compositions and methods for RNA interference with sialidase expression and uses thereof - The present invention provides RNAi agents targeted to sialidase. The RNAi agents include siRNA, shRNA, and expression vectors that comprise a template for transcription of an siRNA or shRNA. The invention further provides cells and cell lines that comprise an RNAi agent targeted to sialidase. The cells and cell lines exhibit reduced sialidase activity relative to control cells that do not comprise an RNAi agent targeted to sialidase. Certain of the cell lines stably express the RNAi agent. The invention further provides methods of producing the cells and cell lines. The invention further provides methods for producing a glycoprotein in cells that comprise an RNAi agent targeted to sialidase. The glycoproteins exhibit an improved sialic acid profile relative to glycoproteins produced by cells that do not comprise an RNAi agent targeted to sialidase. The invention further provides glycoproteins, e.g., therapeutic glycoproteins, produced in the cells. | 08-13-2009 |
