Definitions
- the invention relates to the field of biochemistry, cell biology and medicine. More specifically, the invention relates to a molecular tool, hereinafter called
- vector intended to be used for the introduction of all types of molecules into eukaryotic cells.
- the invention particularly finds its application for the intracellular incorporation of amino acids, or peptides of any size and sequence (dipeptides, tripeptides, polypeptides, proteins, etc.), which can be chemically modified.
- the invention also relates to any molecule vectorized by such a vector.
- vectorized molecule are understood to refer to the assembly constituted by the vector fused with the molecule to be transported in the cell.
- the supply of molecules into eukaryotic cells can be carried out by fusing the molecule to be transported with cellular incorporation modules ("cell-permeable modules” CPM), such as membrane translocation polypeptides, capable of cross cell membranes and gain direct access to the cytoplasmic compartment of cells.
- CPM cellular incorporation modules
- membrane translocation polypeptides capable of cross cell membranes and gain direct access to the cytoplasmic compartment of cells.
- CPMs are already known and used to introduce peptides and proteins, which do not spontaneously cross the membranes of eukaryotic cells.
- CPMs can correspond to natural protein domains (Schwarze et al. 2000. Trends Cell Biol. 10, 290-295, Fujihara and Nadler 1999. EMBO J. 18, 411-419) or to peptides of artificial sequences ( Futaki et al. 2000. J. Biol. Chem. 276, 5836-5840; Ho et al. 2001. Cancer Res. 61, 474-477).
- MDR drug resistance system
- the main application of this prior art is the introduction of proteins or peptides into cells, by means of CPM consisting of translocation peptides.
- the proteins or peptides (X) to be introduced into the cells are prepared in fusion with the CPMs via a peptide bond, in the form of recombinant CPM-X proteins.
- These proteins are produced in appropriate expression systems, for example in bacteria, or else synthesized using peptide synthesizers.
- the recombinant proteins CPM-X are fully incorporated by these cells, and part X can exercise the biological activity for which it is designed (Schwarze et al. 2000. Trends Cell Biol. 10 , 290-295).
- the fact that the CPM remains associated with the molecule X after cellular incorporation can also prevent the appropriate subcellular locahsation of X.
- many translocation peptides currently known have tendencies to accumulate in certain subcellular compartments (linked nuclear localization to an activity "NLS", re secretion etc.), bringing with them the molecule X.
- fusion with a vector can prevent the functioning of certain localization sequences which would have been provided for in the transported molecule X, such as for example a N-terminal mitochondrial addressing signal.
- - CPMs can present, beyond a certain concentration, a certain degree of toxicity for cells and the organism, so as to limit their use in cell and medical biology.
- the possible toxicity can come from the destabilizing properties of the membranes of certain translocation peptides, such as for example fragments of viral envelope proteins or bacterial toxins, or else from the presence of electrically charged domains such as for example the translocation peptides rich in basic amino acids, or polyhistidine sequences, labeling and affinity purification for metals.
- the various modules of the vectorized molecule other than the transported molecule X may present risks of immunogenicity. Such limitations of the state of the art constitute the drawbacks thereof.
- the objective of the present invention is to propose a technique for introducing molecules into eukaryotic cells, using CPMs but presenting new advantages compared to the techniques of the prior art.
- an objective of the present invention is to propose a vector making it possible to transport into eukaryotic cells any type of molecule and in particular any type of peptide, including very short peptides such as simple amino acids, dipeptides or tripeptides, and peptides whose first amino acid is not methionine.
- a vector for the introduction into a eukaryotic cell of a molecule (X) having at least one amino-terminal end characterized in that it is constituted by the association of a cellular incorporation module allowing the membrane translocation, and an ubiquitin or other related conjugable peptide module, said vector having a carboxy-terminal end intended to be fused by peptide reason at the amino-terminal end of said molecule ( X).
- UBL ubiquitin or other related conjugable peptides
- SUMO Small Ubiquitin-related MOdifier
- UCRP Ubiquitin Cross-Reacting Protein
- RUB Related to UBiquitin
- UBL is ubiquitin.
- UBLs are naturally synthesized in fusion with carboxyl terminal extensions, consisting of simple amino acids, polypeptides or proteins. There are cellular enzymatic activities capable of cleaving precisely between the UBL domains and their C-terminal extensions.
- the present invention takes advantage of the natural existence of these enzymes in cells for a new and original objective: the intracellular cleavage of molecules pre-synthesized outside the cells, after incorporation by the cells.
- the presence of a UBL module at the N-terminal part of the transported molecule X in fact allows the cleavage between UBL and X, and therefore the release of the molecule X from the rest of the vector.
- the C-terminal cleavage of UBL is only conditioned by the recognition of the amino acid sequence of the UBL module, located exclusively on the NH2 side of the cleavage site, which makes it possible to introduce any sequence on the COOH side.
- This property makes it possible to impose no condition or restriction as to the nature of the X peptides.
- very short peptides such as dipeptides, can be as efficiently transported according to this invention.
- this amino acid may be different from a methionine, which is not the case for peptides synthesized from transgenes, after transcription and intracellular translation.
- modified or shortened versions of UBL is possible if their ability to induce cleavage at their C-terminal end is preserved.
- Very many types of molecules can be vectorized by the vector according to the invention and in particular simple amino acids and peptides of any size, and independently of any constraint of composition and sequence.
- the vector according to the invention also makes it possible to vectorize chemically modified peptides.
- the vector according to the invention can also be used for the cellular incorporation of non-peptide molecules, such as for example oligonucleotides or hydrophilic chemical compounds which will have been grafted beforehand at the carboxy-terminal end of an oligopeptide. It will also be noted that it will be possible to chemically modify the vector molecules, provided that the peptide bond between the vector molecule and the vector remains accessible for C-terminal hydrolases from PUBL. For example, a C-terminal acylation of the molecule (X) will allow its intracellular membrane anchoring.
- the vector according to the present invention also has advantages compared to the peptides simply associated with membrane translocation peptides as stated previously.
- the present invention allows the intracellular release of the molecules (X) transported, in a form completely free of any fusion after cleavage between UBL and X.
- the physical dissociation between molecule X and the rest of the vector according to the present invention has several advantages: a- The absence of functional interference between the vector and molecule X. If molecule X must ensure a biological function in cells, the efficiency of this function can be considerably reduced if the other modules of the vectorized molecule remain associated with it (CPM, UBL and others). By steric hindrance, these modules can hinder:
- the intracellular release mechanism induced by the UBL module makes it possible to deliver peptides of any size, composition and sequence into cells, in particular having the desired amino- and carboxy-terminal regions, including having an amino acid amino-terminal other than methionine.
- peptides synthesized in situ from transgenes are necessarily synthesized with an initiating methionine in the amino-terminal position, and that the transgenes do not lend themselves well to the synthesis of small proteins and peptides.
- the intracellular dissociation between the molecule X and the vector modules makes it possible to introduce an additional device into this vectorization system: the subsequent destruction of all the modules of the vectorized molecule other than the transported molecule X ( CPM, UBL and others).
- the scheduled destruction of these modules is the second objective of the present invention. In the simplest case where all of the vector components are peptide in nature, this objective is achieved by the introduction of a module into the vectorized molecule.
- destabilization modules can be used for this system, in particular destruction boxes ("destruction boxes”) present in certain naturally unstable proteins such as, for example, swans (Glotzer et al.
- the N-terminal destabilization module (DN, "Destabilizing N-end") is located at the amino-terminal end of the vectorized molecule.
- N-terminal destabilization module The nature of this type of N-terminal destabilization module is based on the observation that the half-life of intracellular proteins is very precisely determined by the nature of the N-terminal sequences and mainly by the nature of the first N-terminal amino acid (Bachmair et al. 1986. Science 234, 179-186). We propose to exploit this natural activity of eukaryotic cells in a new and original way, to program the intracellular destruction of a protein pre-synthesized outside the cells, then incorporated by the cells.
- DN destabilization signals only take effect in the intracellular context, and therefore in no way affect the stability of the recombinant protein in extracellular fluids. This point is demonstrated by the existence of many extracellular proteins which are naturally very stable although having a destabilizing amino acid at their amino-terminal end, exposed after the chvage of the signal peptide secretion.
- A- By enzymatic cleavage of the recombinant protein by a protease: - Or a protease, the recognition site of which is located exclusively on the NH 2 side of the storage site (such as factor Xa for example), having provided a destabilizing residue just downstream from its cleavage site (FIG. 3 A).
- This method is complex but offers the advantage of guaranteeing that the destruction of the vector module will only occur after the C-terminal chvage of UBL, and therefore after the release of the transported molecule X.
- a destabilizing amino acid dictating a very short protein half-life such as arginine for example.
- methods A, B and D are used.
- method B the presence of internal methionines in the recombinant protein must first be avoided.
- the methionine corresponding to the first amino acid of UBL is replaced by a leucine.
- UBL module Several molecules are known that can be used in the context of the present invention to constitute the UBL module, such as ubiquitin, SUMO, NEDD-8, UCRP, RUB or others (see Jentsch and Pyrowolakis, 2000. Trends Coll Biol. 10, 335-342).
- modified or shortened versions of UBL in the context of the present invention is also possible if their capacity to induce cleavage at their C-terminal end is preserved.
- this module is ubiquitin.
- Several methods are known that can be used to constitute the intracellular destabilization module of the vector.
- this module consists of an amino-terminal destabilizing acid followed by a region comprising one or more lysine residues.
- the amino-terminal amino acid destabilizer is glutamine.
- said incorporation module is preferably a membrane translocation peptide such as a peptide derived from the TAT protein of the AIDS virus (HIV), of natural or modified sequence.
- the invention also relates to any vectorized molecule, characterized in that it is constituted by the fusion of a molecule (X) having at least one amino-terminal end of which said amino-terminal end is fused by peptide bond at the end carboxy-terminal of the vector as described above.
- said molecule (X) is an amino acid or a peptide, optionally chemically modified. According to another variant, said molecule (X) is a non-peptide molecule grafted to the carboxy-terminal end of an oligopeptide.
- an N-terminal protein destabilization module can be added to the amino-terminal end of the vectorized protein.
- the modules of the system are of a polypeptide nature
- bacteria bacteria
- eukaryotes for example bacculovirus
- the use of a eukaryotic production system requires ensuring that it does not include the enzymatic activities leading to the C-terminal chvage of UBL. Eventually, these activities, if they exist, must be deactivated beforehand. These problems do not arise for bacterial systems, predominantly lacking these enzymatic activities.
- said vectorized molecule also comprises at least one labeling module.
- this labeling module is a polypeptide such as poly-histidine.
- Such a labeling module could in particular be used to facilitate the purification of the vectorized polypeptide, for example by affinity for metals in the case of polyhistidine.
- said vectorized molecule additionally comprises at least one cell addressing module. It is indeed often desirable to vectorize molecules only in certain specific cell types. Translocation peptides are already known to be preferentially incorporated by certain cell types (Fujihara and Nadler, 1999), but most of the translocation peptides appear to be effective in all tissues (Schwarze et al. 2000. Trends Cell Biol. 10 , 290-295). However, even in this case, addressing to certain defined cells can be specified for this vectorization system, by adding additional modules to the vectorized molecule. For example, it has been shown that the presence of a tripeptide RGD (Arginine - Glycine - Aspartate), allows preferential addressing of metastatic cancer cells, overexpressing ⁇ v / ⁇ 3 integrins.
- RGD Arginine - Glycine - Aspartate
- FIG. 1 shows a vector molecule according to the invention
- FIG. 2 schematically shows the operation of the invention
- FIG. 3 schematically represents methods A B, C and D to expose an amino acid particuher at the N-terminal end of the vectorized molecule (see above);
- a vectorized molecule is constituted by the fusion, of NH2 into COOH, of an intracellular destabilization module 2, of a cellular incorporation module 3 which can for example be constituted by peptide derived from the protein TAT of the AIDS virus (HIV), of an ubiquitin module or other related conjugable peptide (UBL) 4 and of a molecule to be transported 5.
- the vectorized molecule is cleaved between 4 and 5 by a specific hydrolase 6.
- the molecule to be transported 5 can then exercise the biological activity for which it was designed. After release of the molecule to be transported 5, the rest of the vectorized molecule 2-3-4 is destroyed by an intracellular enzymatic system 7 recognizing the destabilization module 2.
- the vectorized molecule 1 is introduced into the extracellular medium A. Thanks to the module of cellular incorporation module 2 which it contains, this molecule crosses the cell membrane C and is found in cytoplasm B. Thanks to a specific hydrolase 6, the peptide bond between molecule 5 and UBL 4 is broken and molecule 5 is released with its free amino-terminal end. This molecule can exert there the biological activity for which it was designed 8.
- the future of the vector l ' constituted by the fusion of the modules 2,3,4, does not have any more influence on the function the transported molecule 5.
- the presence of a destabilization module 2 induces the destruction of the vector l 'by intracellular machinery.
- the invention offers a wide range of applications, from basic research to therapy. Since it does not impose any conditions on the nature of molecule X, it allows the introduction into polypeptides of both natural and artificial sequences. Natural sequence polypeptides can for example correspond to domains of existing proteins. Peptides of artificial sequences can be selected as specific ligands of known regulatory proteins, through screening strategies for random peptide banks, direct or reverse double hybrid, or even computer-aided modeling.
- the UBL module provided in the vector can be used, in which case its C-terminal extension can be any.
- the invention is also directly adaptable to the screening of random peptide banks, which offer billions of possible configurations.
- a library can be constructed by directly using the vector described above, by inserting random nucleotide sequences 3 'to the region encoding the UBL.
- the molecular tools defined in the present invention intracellular release of the transported molecule X and programmed destruction of the other modules of the molecule vectorized, are adaptable to already identified translocation modules or in future developments. They are also adaptable to the administration modalities which will be defined for the cellular incorporation modules.
- the present invention is adaptable to the treatment of any type of pathology, from the moment when effective transported X molecules can be defined for these pathologies.
- the present invention takes advantage of duly confirmed cellular activities in various fields of biology, so that its functionality is largely assured.
- the functionalities of the present invention are set out below. Exposure of any amino acid after cleavage by factor Xa:
- factor Xa The possibility of using factor Xa to expose the desired amino acid at the N-terminal end of a recombinant protein, is guaranteed by its specificity of chvage of this protease.
- the cleavage of FXa is directed by the recognition of a sequence of four amino acids (preferably IEGR) entirely contained on the NH2 side of its cleavage site, which does not impose any condition on the nature of the next amino acid.
- Factor Xa is commercially available and widely used. Release of the molecule transported X inside the eukaryotic cells:
- intracellular ligases graft a destabilizing supernumerary amino acid (often arginine) to the N-terminal end of the proteins to be destroyed.
- transmembrane transport properties are also duly confirmed for numerous translocation peptides according to the prior art.
