Abstract

The present invention provides, as a new anti-cancer agent obtained by combining HVJ-E and a molecule synergistically acting therewith, an anti-cancer agent containing the following (1) and (2):

• (1) HVJ-E (hemagglutinating virus of Japan envelope),
• (2) CXCL2, a nucleic acid comprising a base sequence encoding CXCL2 or a CXCL2 expression inducing agent.

Claims

1. A method for the prophylaxis or treatment of cancer, comprising administering an effective amount of a pharmaceutical composition comprising the following (1) and (2) to a subject:

(1) HVJ-E (hemagglutinating virus of Japan envelope),

(2) CXCL2 or a nucleic acid comprising a base sequence encoding CXCL2.

3. The method according to claim 1, wherein the cancer is selected from the group consisting of melanoma, lung cancer, mesothelioma, tongue cancer, esophagus cancer, gastric cancer, liver cancer, large intestine cancer, prostate cancer, kidney cancer, bladder cancer, breast cancer, uterine cancer, ovarian cancer, brain tumor, thyroid cancer, angiosarcoma, osteosarcoma, chondrosarcoma, rhabdomyosarcoma and leiomyosarcoma.

4. The method according to claim 1, wherein the nucleic acid comprising the base sequence encoding CXCL2 is an expression vector comprising a base sequence encoding CXCL2.

5. The method according to claim 4, wherein the cancer is selected from the group consisting of melanoma, lung cancer, mesothelioma, tongue cancer, esophagus cancer, gastric cancer, liver cancer, large intestine cancer, prostate cancer, kidney cancer, bladder cancer, breast cancer, uterine cancer, ovarian cancer, brain tumor, thyroid cancer, angiosarcoma, osteosarcoma, chondrosarcoma, rhabdomyosarcoma and leiomyosarcoma.

6. The method according to claim 4, wherein the nucleic acid comprising a base sequence encoding CXCL2 is encapsulated in HVJ-E.

7. The method according to claim 6, wherein the cancer is selected from the group consisting of melanoma, lung cancer, mesothelioma, tongue cancer, esophagus cancer, gastric cancer, liver cancer, large intestine cancer, prostate cancer, kidney cancer, bladder cancer, breast cancer, uterine cancer, ovarian cancer, brain tumor, thyroid cancer, angiosarcoma, osteosarcoma, chondrosarcoma, rhabdomyosarcoma and leiomyosarcoma.

8. The method according to claim 1, wherein the nucleic acid comprising a base sequence encoding CXCL2 is encapsulated in HVJ-E.

9. The method according to claim 8, wherein the cancer is selected from the group consisting of melanoma, lung cancer, mesothelioma, tongue cancer, esophagus cancer, gastric cancer, liver cancer, large intestine cancer, prostate cancer, kidney cancer, bladder cancer, breast cancer, uterine cancer, ovarian cancer, brain tumor, thyroid cancer, angiosarcoma, osteosarcoma, chondrosarcoma, rhabdomyosarcoma and leiomyosarcoma.

2. A method of inducing an N1 type neutrophil, comprising administering an effective amount a pharmaceutical composition comprising the following (1) and (2) to a subject:

(1) HVJ-E (hemagglutinating virus of Japan envelope),

(2) CXCL2 or a nucleic acid comprising a base sequence encoding CXCL2.

10. The method according to claim 2, wherein the nucleic acid comprising a base sequence encoding CXCL2 is an expression vector comprising a base sequence encoding CXCL2.

11. The method according to claim 10, wherein the nucleic acid comprising a base sequence encoding CXCL2 is encapsulated in HVJ-E.

12. The method according to claim 2, wherein the nucleic acid comprising a base sequence encoding CXCL2 is encapsulated in HVJ-E.
