- the present invention relates to a method for improving protein expression and a composition for protein expression.
- Protein is extremely promising as a physiologically active substance. For example, protein replacement therapy is effective in treating diseases caused by a decrease in a particular protein. Therefore, techniques for producing a large amount of protein intracellularly or extracellularly have been developed so far.
- Protein is produced by transcription from DNA encoding the protein to mRNA and translation of the protein from the mRNA.
- Transcriptional regulators are involved in transcription of mRNA from DNA, and the amount of mRNA production is controlled by transcriptional regulation.
- protein translation from mRNA is thought to be controlled by the association of translation initiation factors to mRNA. It is also known that mRNA is unstable in cells and its stability varies depending on poly A added to the 3 'UTR of mRNA.
- Poly A is usually added to the 3 'UTR of mRNA by a poly A addition signal.
- a complex containing a cleavage / polyadenylation factor (CPSF) recognizes the poly A addition signal region of the 3′UTR of the mRNA, and 10 to 10 of the signal.
- MRNA is cleaved 30 bases downstream, and poly-A is initiated from the cleavage site. Then, it is considered that the synthesis of poly A is terminated when poly A reaches about 100 to 300 bases (Non-patent Document 1). However, the synthesis of poly A is not strictly controlled.

- PABP poly A binding protein
- mRNA with long poly A binds more strongly to PABP, while the complex formation between mRNA and eIF4E has a specific length of poly A (specifically 240 bases). Sometimes found to be significantly promoted. Further, when the poly A length exceeded a certain value, the binding to PABP was strengthened, while the binding to eIF4E was weakened. Since eIF4E is thought to bind to (or form a complex with) mRNA polyA via PABP, eIF4E binding to eIF4E is reduced in mRNA having a long polyA that increases the binding between mRNA and PABP. The result of weakening was very surprising.

- This protein expression plasmid was replicated in Escherichia coli by a conventional method, then purified and used in the following examples.
- Example 2 Protein binding ability of mRNA
- the ability of mRNA to bind to protein was confirmed.
- a plasmid having a 120, 180 or 210 base chain length poly A was converted to a linear DNA with typeIIS type restriction enzyme BsmBI and purified by agarose electrophoresis.
- the 240, 270 or 360 base chain length plasmid was converted into linear DNA using two types of restriction enzymes BsmBI and HpaI, and purified by agarose electrophoresis.
- the purified linear DNA has a luciferase gene under the control of the T7 promoter.
- mRNA was prepared by in vitro transcription according to the manufacturer's manual.
- FIG. 1 shows the results of electrophoresis of mRNA having A (120), A (240) and A (360).
- MRNA bound to nuclear protein was obtained as follows. That is, Huh7 cells were seeded at 5,000 cells / well in a 96-well plate and cultured for 24 hours. As the medium, DMEM containing 10% FBS was used. 190 ng of GLuc mRNA having various lengths of poly A purified in Example 1 was introduced into Huh7 cells using a gene introduction reagent LipofectamineLTX (Life Technologies). 24 hours after introduction, a cell lysis sample was obtained using Dynabeads Co-Immunoprecipitation Kit (Life Technologies, Inc.).
- the binding between mRNA and protein was confirmed by immunoprecipitation. That is, the amount of mRNA that was precipitated by precipitating mRNA that bound to these proteins and formed a complex using an antibody against PABP or eIF4E was used as an indicator of protein binding. Specifically, anti-PABP antibody (Abcam, catalog number ab21060) and anti-eIF4E antibody (Santacruz, catalog number sc-13963) were used as antibodies. In the immunoprecipitation reaction, the antibody and the protein were bound by incubating at 4 ° C. for 30 minutes using Dynabeads Co-Immunoprecipitation Kit (Life Technologies).
- RNA was collected using RNeasy® Mini® Kit (QIAGEN), and cDNA was prepared from mRNA contained in the total RNA by RevertraAce® qPCR® RT® Master® Mix® with “gDNA® Remover® (TOYOBO)”.
- the amount of GLuc® mRNA that bound to the protein and precipitated was quantified by quantitative polymerase chain reaction (quantitative PCR) using ABI® Prism® 7500® Sequence® Detector® (Applied® Biosystems). As primers, forward primer: 5'-TTGAACCCAGGAATCTCAGG-3 'and reverse primer: 5'-CACGCCCAAGATGAAGAAGT-3' were used. And the amount of mRNA in the case of poly A length 120 was set to 1, and the quantitative result was standardized. The result was as shown in FIG.

- mRNA having A (240) ie, poly A length is 240 bases
- mRNA having A (120) ie, poly A length is 120 bases
- mRNA with A (360) bound more PABP than mRNA with A (240). From this, it was confirmed that mRNA having a long poly A length can be advantageously bound to PABP.
- FIG. 2B mRNA with A (240) was shown to bind significantly more eIF4E than mRNA with A (120) or A (360). It was revealed that a specific length of poly A was suitable for binding to eIF4E, suggesting that too long poly A may inhibit binding to eIF4E.
- PABP is known to bind to poly A of mRNA, and the result that it binds favorably to mRNA having a long poly A was an expected result. Since eIF4E was also thought to bind to polyA of mRNA via PABP, it was similarly expected to bind favorably to mRNA with long polyA. However, according to the above results, eIF4E binds strongly to mRNA having a specific length of poly A (specifically, mRNA having A (240)), while A (120) or A (360) It was shown to bind significantly more strongly than mRNA with That is, in the mRNA having A (360), the binding to eIF4E was unexpectedly weakened despite the strong binding to PABP.
- Example 3 Translation efficiency of protein from mRNA in vitro
- the translation efficiency of protein from the obtained mRNA was examined.
- Huh7 cells were seeded in a 96-well plate at 5,000 cells / well and cultured for 24 hours.
- DMEM containing 10% FBS was used as the medium.
- 190 ng of GLuc mRNA having various lengths of poly A purified in Example 1 was introduced into Huh7 cells using the gene introduction reagent Lipofectamine LTX (Life technologies). Further, as a control, mRNA to which poly A was enzymatically added using a poly A addition signal was prepared.
- the pSP73-Luc plasmid obtained in Example 1 was digested with the restriction enzyme NdeI.
- Quantification was performed based on the amount of luminescence from luciferase. Specifically, the amount of luciferase luminescence from each mRNA was measured with GloMax TM 96 microplate luminometer (Promega) using Renilla® Luciferase assay system (Promega). The amount of luminescence was determined as relative luciferase units (RLU). The result was as shown in FIG.
- mRNA having A (120), A (180) or A (210) showed almost the same level of protein expression.
- mRNA with A (240) showed significantly higher levels of protein expression compared to these. This increase in expression was statistically significant.
- mRNA with A (270) or A (360) was statistically significantly lower in protein expression compared to mRNA with A (240). From this result, it was revealed that when the poly A length is 240, the protein expression is significantly enhanced as compared with the case where the poly A length is 210 or 270. And that the translation efficiency was remarkably reduced by mRNA having A (27) suggests that poly A having 270 bases or more has an activity to inhibit translation.
- MRNA with A (90) showed the same level of protein expression as mRNA with A (120) (data not shown).
- AATAAA poly A addition signal
- the control only an RLU equivalent to mRNA having A (360) was shown. That is, the expression level of the target protein from the mRNA having A (240) far exceeded the expression level from the mRNA with poly A added enzymatically similar to natural mRNA.
- a (180), A (210), A (240), A (270), and A (360) include a restriction enzyme site-derived intervening sequence (GAUG sequence) between poly A and poly A. .
- GAUG sequence a restriction enzyme site-derived intervening sequence between poly A and poly A.
- a (120) and A (60) -GAUG-A (60) were prepared in the same manner as described above, and the expression levels were compared.
- a (60) -GAUG -A (60) showed an expression level of about 80% of A (120), and it was revealed that the influence of the intervening sequence was limited (data not shown).
- Example 4 Efficiency of protein translation from mRNA in vivo
- the expression efficiency of luciferase protein in mouse skeletal muscle was examined.
- the NLuc mRNA having A (120), A (240) or A (360) obtained in Example 1 was used. For administration, it was encapsulated in a nanomicelle type carrier (PLoS One 8 (2): e56220, 2013) encapsulating mRNA. Specifically, as the block copolymer constituting the nano micelle, the number average molecular weight of the PEG block portion is 12,000, and the number average degree of polymerization of the Asp (DET) block portion is 65.

- PEG-PAsp (DET) and mRNA were each dissolved in 10 mM HEPES buffer, and both were mixed to prepare a nanomicelle solution.
- a nano micelle solution having an N / P ratio of 8 was prepared by setting the molar ratio of the amino group (N) of PEG-PAsp (DET) to the phosphate group (P) of mRNA as the N / P ratio.
- mice were administered to the lower limb skeletal muscles of mice by the hydrodynamics method. Specifically, after anesthetizing the mouse with 3% isoflurane (Abbott Japan), a tourniquet was placed in the proximal part of the thigh to temporarily block the circulation of the lower limbs. Then, 300 ⁇ L of a nano micelle solution containing 5 ⁇ g of mRNA was administered over 5 seconds from the great saphenous vein behind the ankle condyle, and the tourniquet was removed 5 minutes later.
- the amount of luciferase protein expressed in skeletal muscle 72 hours after administration was quantified. Specifically, the lower limb skeletal muscle 72 hours after administration was collected, and the tissue was homogenized using a multi-bead shocker (Yasui Kikai). The luciferase protein was quantified based on the amount of light emitted from the lucifer back. The amount of luminescence was quantified using a Nano-GLoiferLuciferase assay system (Promega) and a Lumat LB9507 luminometer (Berthold), and the amount of luminescence was standardized by the protein concentration in the cell lysate.
- the mRNA having A (240) showed a protein expression at a significantly higher level than the mRNA having A (120) or A (360).
- Example 5 Treatment of Sciatic Nerve Injury Model Mice
- IGF-1-expressing mRNAs having different lengths of poly A were administered to sciatic nerve injury model mice to confirm the therapeutic effect.
