Abstract
- Cervical cancer is strongly associated with chronic human papillomavirus infections, among which HPV16 is the most common. Two commercial HPV vaccines, Gardasil and Cervarix are effective for preventing HPV infection, but cannot be used to treat existing HPV infections. Previously, we developed a human endogenous retrovirus (HERV)-enveloped recombinant baculovirus capable of delivering the L1 genes of HPV types 16, 18, and 58 (AcHERV-HP16/18/58L1, AcHERV-HPV). Intramuscular administration of AcHERVHPV vaccines induced a strong cellular immune response as well as a humoral immune response. In this study, to examine the therapeutic effect of AcHERV-HPV in a mouse model, we established an HPV16 L1 expressing tumor cell line. Compared to Cervarix, immunization with AcHERVHPV greatly enhanced HPV16 L1-specific cytotoxic T lymphocytes (CTL) in C57BL/6 mice. Although vaccination could not remove preexisting tumors, strong CTL activity retarded the growth of inoculated tumor cells. These results indicate that AcHERV-HPV could serve as a potential therapeutic DNA vaccine against concurrent infection with HPV 16, 18, and 58.

Abstract
- Methanol extract prepared from the fruitbody of Phellinus linteus (EPL) showed anti-tumor and immuno-stimulating activities. The invasion activity of B16-F10 melanoma cells through a reconstituted basement membrane to the collagen-coated lower surface of the filters was inhibited about 67% by EPL (100 ug/ml). Also, EPL inhibited the expression of the mRNA for MMP-2 and MMP-9. In vivo treatment of C57BL/6 mice (150 mg/kg) with EPL for 14 days, the pulmonary colonization was found to be inhibited about 75%. Using reverse transcriptionpolymerase chain reaction (RT-PCR) analysis, we found that cytokine IL-12 and INF-[gamma] genes were induced by EPL. Furthermore, EPL stimulated the proliferation of CD4^+ (33.5%) and CD8^+ (17.7%) in mouse splenocytes.
