Definitions
- the present invention relates to the production of recombinant human factor VII in the milk of transgenic rabbits.
- Factor VII is a plasma protein involved in the process of blood coagulation, and in particular in the initiation of the extrinsic coagulation pathway.
- Factor VII which is a vitamin K-dependent glycoprotein, is synthesized in the liver as a 466 amino acid precursor comprising a signal peptide (residues 1-20) and a propeptide (residues 21-60).
- Factor VII circulating in blood plasma is a zymogen (or proenzyme) consisting of a peptide chain of 53 kDa containing 406 residues.
- Factor VII is activated by factor VIIa by proteolytic cleavage between arginine at position 152 and isoleucine at position 153:
- Factor VIIa is composed of a 152 amino acid light chain derived from the N-terminus of a molecular weight of about 20 kDa and a 254 amino acid heavy chain derived from the C-terminus of a molecular weight of about 30 kDa, which are covalently linked together by a disulfide bridge between the cysteines in position 135 and 262.
- Circulating factor VII may complex with the tissue factor (TF) produced by subendothelial fibroblasts, when this is released during a breach in the vascular endothelium.
- TF tissue factor
- the formation of this complex is accompanied by the activation of factor VII factor VIIa.
- the TF-VIIa complex activates factors IX and X, resulting in the formation of factors IXa and Xa, which in turn activate the conversion of prothrombin to thrombin, which allows the conversion of fibrinogen to fibrin, resulting in clot formation.
- the factor VlI / VIIa has been used for many years to treat patients with different haemostasis disorders (for example hemophilia type A, which corresponds to a deficiency of factor VIII, haemophilia type B which corresponds to a deficiency in factor IX, or hereditary deficits in factor VlI / VIIa), as well as hemorrhagic accidents of various origins such as cerebrovascular accidents, or hemorrhagic traumas.
- haemostasis disorders for example hemophilia type A, which corresponds to a deficiency of factor VIII, haemophilia type B which corresponds to a deficiency in factor IX, or hereditary deficits in factor VlI / VIIa
- hemorrhagic accidents of various origins such as cerebrovascular accidents, or hemorrhagic traumas.
- the factor VII preparations used were obtained from human plasmas.
- recombinant factor VII preparations produced by transformed mammalian cells are presently preferred. for expressing human factor VII, as described, for example, in Application EP 0 200 421.
- An alternative to the production of proteins of therapeutic interest by transformed cell cultures is their production by transgenic animals, and in particular in milk of these. This approach theoretically has many advantages, including a higher yield, a lower production cost than cell culture production, and an increase in production more easily and more flexible at the industrial level.
- these factors include the ability of the host species to produce in industrializable quantities, proteins with post-translational modifications similar to those of the native human protein. This factor is particularly critical if it is envisaged to produce in recombinant form in milk proteins such as factor VII, whose post-translational modifications are multiple and varied (cleavage of the signal peptide and the propeptide, ⁇ -carboxylation, ⁇ - hydroxylation, O-glycosylation and N-glycosylation), which are naturally produced in the liver. Indeed, the cells of the mammary gland have different post-translational modification capacities than those of the liver cells.
- transgenic mice expressing human protein C in their mammary glands could not properly perform propeptide cleavage and gamma-carboxylation (Drohan et al., Transgenic Res., 355-64, 1994). . Similar observations have been made in transgenic pigs for both protein C and factor IX (Lee et al., J. Biochem., 118, 81-7, 1995, Van Cott et al, Genet Anal., 15, 155). -60, 1999).
- the O-glycosylation and the N-glycosylation of the proteins can vary, qualitatively and quantitatively depending on the mammalian species concerned.
- the human proteins do not comprise a galactose-galactose ⁇ (1-3) galactose unit (Gal ⁇ 1-3Gal motif), since the gene coding for alpha-1,3-galactosyltransferase, responsible for the synthesis of this motif, is inactivated in humans and Old World monkeys (Europe, Asia) while present in other mammals.
- This motif (also called ⁇ -Gal epitope) is consequently highly immunogenic in humans (GALILI et al, Blood, 82 (8): 2485-2493, 1993).
- a glycosylated human protein produced in recombinant form in mammals possessing an active alpha 1,3 galactosyltransferase is therefore likely to carry a large amount of Gal ⁇ 1-3Gal motifs and may cause significant undesirable immune reactions.
- transgenic rabbits expressing in their mammary glands a sequence coding for human factor VII produced in their milk a correctly cleaved recombinant factor VII, and furthermore not containing or containing only very few Gal ⁇ l-3Gal patterns.
- the present invention therefore relates to a transgenic rabbit expressing a human factor VII in its milk.
- a transgenic rabbit according to the invention contains in its genome one or more copies of a transgene comprising a polynucleotide encoding a human factor VII, placed under the transcriptional control of a promoter allowing its specific expression in the mammary gland cells of said rabbit. .
- transgene is meant a nucleic acid construct stably inserted into the genome of a host organism, which is transmitted to its offspring from generation to generation.
- the transgene allows expression of a protein of interest (factor VII) in the transgenic host animal milk.
- Promoters for the specific expression in mammary gland cells of the rabbit are known per se.
- they may be promoters of casein genes or milk serum proteins: mention will be made in particular of the ⁇ , ⁇ , or K casein promoters, the ⁇ -lactoglobin promoter, the P-lactalbumin promoter and the WAP (whey acidic protein) promoter; , or that of lactoferrin.
- It may be a promoter from the rabbit, such as the WAP promoter described in Application EP0527063, or a promoter from another mammalian species.
- the polynucleotide encoding human factor VII is preferably a cDNA, or the coding portion (ORF) thereof. It can be the natural cDNA of factor VII, the sequence of which is known per se, and available on the databases, for example under accession number Ml 3232, or a sequence coding for a modified human factor VII variant in particular to increase its activity and / or to eliminate its undesirable effects; by way of examples, mention may be made of the variants described in Application 2008/0010693 or that described in the publication by Sorensen et al. (Br. J. HaematoL, 137 (2): 158-65, 2007). It is advantageous to use a DNA sequence optimized for expression in the mammary glands of rabbits.
- Such a sequence can be obtained in silico by techniques well known to those skilled in the art, in order to eliminate cryptic splice sites, A / T rich sequences, destabilizing mRNAs, polyadenylation sites as well as that potentially parasitic TATA boxes, and CpG islands, and optimize the codons to reflect the preferences of the mammary gland cells of rabbits to produce milk proteins.
- the transgene contains, besides the promoter and the coding sequence for factor VII, other elements intended to optimize the transcription and / or the translation of the recombinant protein.
- elements are known in themselves to those skilled in the art (see, for example, Houdebine et ah, in: Cari A. Pinkert (ed), Vector Design for Transgene Transgenic Expression Animal Technology, 2nd edn, New York Academy Press, 419-458, 2002).
- a strong isolator placed at 5 'of the promoter, guaranteeing a level of expression of the protein dependent on the number of transgene copies integrated and independent of the site of integration of the transgene into the genome of the animal: for example the 5 ⁇ S4 region of the chicken beta-globin gene (Taboit-Dameron et al., Transgenic Res., 8: 223-235, 1999; Rival-Gervier et al., Transgenic Res., 12: 723). - 730, 2003).
- exon / intron pairs which may contain one or more transcription or translation enhancers: by way of examples, mention may be made of: the introns of the late and early genomes of the SV40 virus genome, the first intron of a beta-globin gene, EF1 alpha gene introns, Palpha-sl casein introns, WAP gene introns, human and bovine growth hormone genes introns; the "enhancer” sequences can in particular be chosen from those present in the LTR sequences of the HTLV virus, or the MMTV virus (murine mammary tumor virus), the "enhancer” sequence of the immunoglobin gene, the “enhancer” sequence of the gene alpha-1 casein, the "enhancer” sequence of beta-globin.
- the "enhancer” sequence may also be the distal region upstream (up to 140 kbp) of the WAP gene or the downstream distal region (at least 10 kbp) of the WAP gene, as described by Rival-Gervier and al. (Mol Reprod Develop, 63: 161-167, 2002), in Application EP 1 217 071
- terminators of the SV40 early or late genes those of the beta-globin genes, WAP genes, human or bovine growth.
- Transgenesis can be carried out by conventional methods known per se.
- the transgene is introduced by micro-injection into the pronuclei of fertilized embryos which are then reimplanted in carrier females.
- transgenic animals is also possible by cloning by nuclear transfer followed by embryo transfer in recipient females.
- the subject of the present invention is also the milk produced by the transgenic rabbits in accordance with the invention, and the use of this milk as a raw material for the purification of recombinant human factor VII.
- Recombinant human factor VII can be purified from this milk by methods known per se, for example as described in US Pat. No. 6,268,487.
- the transgenesis vector used for cloning is derived from the plasmid pPolylII, having an ampicillin resistance gene as well as the bacterial origin of replication Col El.
- This transgenesis vector contains an expression cassette comprising: a dimer of the sequence of the 5 ⁇ S4 isolator of the chicken beta-globin gene (Genbank U78775) (Recillas-Targa et al, Proc Natl Acad ScL 5 : 6883-6888, 2002) upstream of the WAP promoter (whey acidic protein; Genbank X52564) of 6.3 kbp rabbit (Rival-Gervier et al, Transgenic Res., 6: 723-730, 2003), the first intron of the rabbit beta-globin gene (Genbank V00882) containing a transcription enhancer ; a second transcription amplifier (SUR 1.2.3) containing the 5 'UTR sequence of the SV40 early genes fused with the R region and the beginning of the U5 region of HT
- the FVII encoding DNA insert recovered by MlullNhel digestion from the intermediate vector, was inserted between the MwI and NheI sites of the expression cassette.
- the resulting transgenesis vector is shown in Figure 1. It contains an insert which is constituted in its 5 'to 3' orientation by i) the dimer of the 5 ⁇ S4 isolator sequence of the chicken beta-globin gene, ii) the 6.3 kbp rabbit WAP (whey acidic protein) promoter, iii) the intron containing the first transcription enhancer, iv) the second transcription enhancer, v) the human factor VII cDNA, vi) the third transcriptional amplifier; and vii) the transcription terminator.
- the colonies containing the recombinant vector are selected on the basis of their resistance to ampicillin, and then the presence of the insert is monitored by restriction fragment analysis, followed by sequencing.
- Transgenic rabbits were obtained by the conventional microinjection technique (Brinster et al, Proc Natl Acad Soi 82: 4438-4442, 1985).
- transgenesis vector containing the recombinant factor VII coding sequence was digested with the NotI restriction enzyme and the insert containing the transgene was isolated on agarose gel and then purified on ElutipD (Schleicher-Schuell,
- Microinjection of oocytes taken and implantation On the 4th day, 18-19h after the mating, the embryos are taken from the donor rabbits to carry out microinjection of DNA: the microinjection of DNA takes place just after samples (15-25 h after mating).
- the one-cell stage embryos are placed in a micro-drop of medium under an inverted microscope equipped with Normarsky objectives and micro-manipulators. Individual embryos are positioned and secured using a pipette.
- Intact unicellular embryos are then reimplanted under general anesthesia into the lumen of the oviducts of the synchronized recipient rabbits (10 embryos in each oviduct), using a surgical procedure (the oviducts are externalised by laparotomy). Parturition may occur naturally 29-31 days after embryo transfer. If necessary, oxytocin injection is initiated on the 31st day. The number of rabbits born in relation to the number of reimplanted embryos is of the order of 5 to 20%. EXAMPLE 3 SELECTION AND CHARACTERIZATION OF TRANSGENIC RABBITS
- the microinjected recombinant DNA integrates the genome randomly. Newborn rabbits (10 days) are tested for the presence of the transgene by an ear biopsy. The genomic DNA is extracted and PCR (Polymerase Chain Reaction) analysis is performed using primers specific for the recombinant insert.
- PCR Polymerase Chain Reaction
- the lineages of the FO founders were further characterized by i) analyzing the number of transgene copies integrated into their genome, and ii) determining the number of integration sites.
- the number of copies of the transgene integrated into the genome of each FO founder line was determined by quantitative PCR and Southern blotting. This number varies, depending on the line, from 1 copy per cell to more than 200 copies per cell.
- the number of integration sites has also been determined by Southern blotting. This number varies, depending on the line, from 1 to more than 5 sites per genome.
- Detection was performed by chemiluminescence (Amersham Biosciences) to determine the human factor VII concentration for each of the milks obtained. An expression level of factor VII varying between 90 ⁇ g / ml and 11 mg / ml was observed. The influence of the number of copies of the transgene on the level of expression has also been sought. The results are illustrated in Figure 2, and show a correlation between the transgene copy number and the expression level of factor VII in the milk of transgenic animals.
