- GGA treatment (-) NP synthesis was significantly enhanced over 24 hours after infection, while with GGA treatment (+), the enhancement of HS P70 synthesis ability was observed at the early stage of infection, and NP The synthesis power of S 12 started after 2 hours. However, it was found that the synthesis ability was suppressed as compared with the GGA treatment (-).
- FIG. 9 shows that the ability of PR8 to synthesize viral proteins such as HA (influenza hemagglutinin protein), NP, Ml (matrix protein), and NS1 (nonstructural protein) is remarkable compared to the control. It is evident that it has been suppressed. The inhibitory effect was strongly correlated with the expression time of HSP70.
- FIG. 10 is a diagram showing the results of densitometry analysis of the protein amount of the sample used in FIG. 9 at 3, 6, 12, and 24 hours after infection. From the results of FIG. 10, expression of HSP70 was observed up to 12 hours after infection with PR8.
- FIG. 11 shows the results of Western blot analysis of the accumulation of HSP70 and NP proteins in cells 12 hours after infection with PR8 according to the present invention. The results confirmed that NP synthesis was not observed in the virus-uninfected mock, and that GGA treatment induced HSP70 and inhibited NP expression 12 hours after infection. Was significantly suppressed by the synthesis of HSP70.
- FIGS. 12 and 13 the effect of GGA treatment on the expression of antiviral genes during PR8 infection was examined, and the results are shown in FIGS. 12 and 13. From Fig. 12, GGA treatment of A549 cells by the Northern blot method resulted in PR8 infection. At times, the expression of HSP mRNA was enhanced, and with it, it was confirmed from FIG. 12 that the expression of the MxA gene, which is an antiviral gene (particularly, orthomyxovirus), was also increased. GAPDH in FIG. 12 was used as a control, as in FIG. 5 described above.
- FIG. 13 shows the results of quantifying the mRNA expression of an interferon-inducible double-stranded RNA-activating protein kinase (hereinafter referred to as “PKR”) having an antiviral effect by the RT-PCR method. From the results, it was found that the expression of PKR in A549 cells was increased by GGA treatment, and its mRNA was also up-regulated. In this figure,
- GGA acts on the MxA gene and PKR. It strongly indicates in terms of the mechanism of action that it is effective in the prevention and treatment of viral infections, especially influenza virus infection, and at the same time, GGA is an antiviral factor activity enhancer or protein kinase inducer. It indicates that there is.
- GGA has an inhibitory effect on influenza virus in in vivo and remarkably improves the clinical symptom of weight loss. It was suggested that synthesis promotion was deeply involved.
- GGA strongly induced HSP70 expression and inhibited influenza virus replication at the same time as the induction. Furthermore, GGA activates the antiviral genes MxA and PKR on the host side in viral infectious diseases, and is found to enhance the host's host defense ability against virus infection. It is effective in preventing and treating influenza virus. It turned out to be. Industrial applicability
