    摘要: Methods for altering the N-glycosylation pattern of proteins in higher plants are provided. The methods comprise introducing into the plant a recombinant construct that provides for the inhibition of expression of α1,3-fucosyltransferase (FucT) and β1,2-xylosyltransferase (XylT) in a plant. Use of these constructs to inhibit or suppress expression of both of these enzymes, and isoforms thereof, advantageously provides for the production of endogenous and heterologous proteins having a “humanized” N-glycosylation pattern without impacting plant growth and development. Stably transformed higher plants having this protein N-glycosylation pattern are provided. Glycoprotein compositions, including monoclonal antibody compositions, having substantially homogeneous glycosylation profiles, and which are substantially homogeneous for the G0 glycoform, are also provided.

    摘要: The present invention provides methods and compositions for the production of recombinant plasminogen, microplasminogen, and fragments thereof in a duckweed expression system. It is the novel finding of the present invention that a duckweed expression system may be used to produce high levels of plasminogen and microplasminogen. The duckweed-produced plasminogen and microplasminogen can be activated to produce a polypeptide having protease activity. Thus, the invention encompasses methods for the expression of plasminogen, microplasminogen, and fragments thereof in duckweed, duckweed plants that are transformed with expression cassettes for the expression of plasminogen, microplasminogen, and fragments thereof, and nucleic acids comprising nucleotide sequences encoding plasminogen, microplasminogen, and fragments thereof, where these nucleotide sequences are modified to enhance their expression in duckweed.

    摘要: Glycan-optimized monoclonal antibodies that specifically bind CD20 antigen and which have improved effector function are provided. The anti-CD20 antibodies of the invention have a glycosylation pattern that results in an antibody composition having predominately the G0 glycoform, and thus comprise N-glycans that lack fucose (i.e., afucosylated) and galactose residues attached thereto. In some embodiments, these anti-CD20 antibodies comprise the light chain and heavy chain sequences of the rituximab anti-CD20 antibody, and thus represent afucosylated rituximab. Methods for producing these glycan-optimized anti-CD20 antibodies are also provided.

    摘要: Compositions and methods for producing aglycosylated plasminogen (PLG) polypeptides and fragments and variants thereof are provided. Compositions of the invention include isolated nucleic acid molecules encoding aglycosylated PLG polypeptides in which the asparagine (Asn) residue corresponding to residue Asn-289 of the mature human PLG polypeptide has been substituted with an amino acid residue that does not support N-linked glycosylation at that position of the PLG polypeptide, as well as the aglycosylated PLG polypeptides encoded thereby. Expression constructs comprising these PLG-encoding nucleic acid molecules and transgenic plants comprising these expression constructs are also provided. Methods of the invention comprise introducing a PLG-encoding nucleic acid molecule of the invention into a plant of interest and culturing the plant under conditions to produce the aglycosylated PLG polypeptide. The aglycosylated PLG polypeptide allows for significant increases in production and yield of PLG from a plant-based expression system without comprising the ability of the PLG product to be activated to a polypeptide capable of binding fibrin and having serine protease activity, including biologically active plasmin that is also glycosylated. The activated aglycosylated plasmin is useful to treat diseases or conditions associated with a thrombus.
