- the specifically amplified 661 bp band was separated by electrophoresis and extracted. This was further cut with EcoR I and Sal I, and the resulting 564 bp band was separated and extracted. This was inserted into a pMEXneo expression vector (5916 base pairs) double-cut with EcoR I and Sal I to obtain trunc.
- PG-FGF-1 / pMEXneo This expression vector contains the nucleotide sequence of SEQ ID NO: 5, which encodes a protein having the amino acid sequence of SEQ ID NO: 6 in mammalian cells.
- the obtained trunc. PG-FGF-1 / pMEXneo was transfected into COS-1 cells (monkey kidney-derived cell line) by the lipofection method. By culturing in a serum-free medium, the protein synthesized in the medium was secreted, and the culture supernatant was collected 3 days later. The obtained conditioned medium was centrifuged at low speed, and the supernatant was stored at 4 ° C.
- the conditioned medium of trunc. PG-FGF-1 protein secreting cells was dialyzed against distilled water and concentrated by freeze-drying. Add this to the electrophoresis buffer (containing SDS, 2-mercaptoethanol). Boiled together to prepare a sample for electrophoresis. Perform electrophoresis using 12.5% acrylamide gel in the presence of SDS and 2-mercaptoethanol.Transfer electrically to nitrocellulose membrane, anti-FGF-1 monoclonal antibody, horseradish peroxidase-labeled anti-mouse. The cells were stained with an IgG antibody and detected by a chemiluminescence method. The results are shown in Figure 1.
- the left line shows the migration position of the standard protein with a known molecular weight and its molecular weight (unit: dalton).
- the migration position of the molecular weight marker is shown on the left.
- PG-FGF-1 protein is a protein with 183 amino acid residues as shown in SEQ ID NO: 6. It is expressed as an unmodified simple protein.If secreted, it should give a band around 20 kDa. It is. However, it was actually detected as a smear band around 40 to 100 kDa. This is a characteristic pattern for proteins modified with glycosaminodalican sugar chains. It is considered that the smear is caused by the uneven length of glycosaminodalican sugar chains.
- PG-FGF-1 treated with a mixture of heparanase and heparitinase HP, ase & HS, ase
- HP, ase & HS, ase completely eliminates the smear band and gives two bands at 21 kDa and 25 kDa.
- S / FGF-la-II is a mixture of heparanase and heparitinase (HP 'ase &HS' ase) alone, and although some of the molecules are reduced in molecular weight, it is not possible to completely eliminate the smear band.
- the physiological activity of trunc. PG-FGF-1 protein as a growth factor was evaluated.
- FGF-1 binds to a target cell receptor and exerts its biological activity, coexistence of heparin or heparan sulfate is essential. Therefore, we targeted a cell line that expressed the FGF receptor (Rlc type) on mouse Ba / F3 cells (a cell line derived from pro B cells), which are known not to express endogenous heparan sulfate.
- the cell growth promoting activity of trunc. PG-FGF-1 protein was evaluated in the presence or absence of heparin. The evaluation of the cell growth promoting activity was based on the measurement of the number of living cells using Tetracolor One.
- Ba / F3 cells expressing the FGF receptor were seeded on a 96-well plate, and at the same time, crudely purified trunc. PG-FGF-1 protein was added at various concentrations. At this time, 10 ug (microgram) co-existing and non-co-existing heparin were prepared. Forty-eight hours later, Tetracolor One was added with 10 ⁇ l (micro-liter) of casket, and the mixture was kept warm for 4 hours, and then the absorbance at 450 nm was measured.
- the cell growth promoting activity is represented by the ratio of the absorbance at 450 nm in the presence of each growth factor, with the absorbance at 450 nm when the cells are cultured in a growth medium (containing IL-3) of Ba / F3 cells.
- the S / FGF-la-II protein shows activity at high concentrations (10-100 ng / ml) even without heparin (triangular dashed line).
- PG-FGF-1 protein exhibits activity even at a low concentration of 1 to 10 ng / ml without coexisting with henolin (circled line). Its activity is comparable to the case where heparin coexists with simple protein FGF-1 (solid line) and has a higher specific activity than S / FGF-la-II. Based on the above results, the S / FGF-la-II protein and trunc.
- PG-FGF-1 protein have a heparan sulfate sugar chain in their own molecules (see Fig. 2), which substitutes for the function of heparin. It is thought that it is.
- the S / FGF-la-II protein has not only a heparan sulfate sugar chain but also a chondroitin sulfate sugar chain, which is thought to contribute to exerting its activity. Specific activity is not very high.
- PG-FGF-1 protein is almost exclusively modified with heparan sulfate sugar chain, it is considered that high specific activity was obtained.
- the novel heparan sulfate sugar chain-added henon-binding protein of the present invention has excellent stability such as heat resistance, acid resistance, alkali resistance, and protease resistance, and has high biological activity. Therefore, the use of the heparan sulfate sugar chain-added heparin-binding protein of the present invention in pharmaceuticals provides excellent in vivo stability, especially acid resistance, alkali resistance, and immature stability. Drugs that can be applied to medicines and have high medicinal effects can be designed.
