The present disclosure relates to developing cell lines where specific biological pathways are modified, particularly by modifications in the enzymes of the cell. The present disclosure develops protein expression systems wherein specific modification of glycan chain of the protein is achieved, which produces non-fucosylated proteins, including non-fucosylated antibodies. The non-fucosylated proteins are used in developing therapeutic monoclonal antibodies and biomarkers, and in diagnosis and prognosis of various diseases. The present disclosure employs the Transcription Activator like Effector Nuclease (TALEN) technology for inactivating fucosylation in a cell. |
