Preclinical evaluation of herpes simplex virus armed with granulocyte-macrophage colony-stimulating factor in pancreatic carcinoma

AIM: To investigate the therapeutic efficacy and mechanisms of action of oncolytic-herpes-simplex-virus encoding granulocyte-macrophage colony-stimulating factor(HSVGM-CSF) in pancreatic carcinoma.METHODS: Tumor blocks were homogenized in a sterile grinder in saline.The homogenate was injected into the right armpit of each mouse.After vaccination,the mice were randomly assigned into four groups: a control group,a high dose HSVGM-CSFgroup [1 × 107plaque forming units(pfu)/tumor],a medium dose HSVGM-CSF group(5 × 106pfu/tumor) and a low dose HSVGM-CSF group(5 × 105pfu/tumor).After initiation of drug administration,body weights and tumor diameters were measured every 3 d.Fifteen days later,after decapitation of the animal by cervical dislocation,each tumor was isolated,weighed and stored in 10% formaldehyde solution.The drug effectiveness was evaluated according to the weight,volume and relative volume change of each tumor.Furthermore,GM-CSF protein levels in serum were assayed by enzyme-linked immunosorbent assays at 1,2,3 and 4 d after injection of HSVGM-CSF.RESULTS: Injection of the recombinant mouse HSV encoding GM-CSF resulted in a significant reduction in tumor growth compared to the control group,and dosedependent effects were observed: the relative tumor proliferation rates of the low dose,medium dose and high dose groups on 15 d after injection were 45.5%,55.2% and 65.5%,respectively.The inhibition rates of the tumor weights of the low,middle,and high dose groups were 41.4%,46.7% and 50.5%,respectively.Furthermore,the production of GM-CSF was significantly increased in the mice infected with HSVGM-CSF.The increase in the GM-CSF level was more pronounced in the high dose group compared to the other two dose groups.CONCLUSION: Our study provides the first evidence that HSVGM-CSFcould inhibit the growth of pancreatic cancer.The enhanced GM-CSF expression might be responsible for the phenomenon.

EFFECTS OF GRANULOCYTE-MACROPHAGE COLONY STIMULATING FACTOR GENE ENCODED VACCINIA VIRUS VECTOR ON MURINE PULMONARY METASTATIC MELANOMA

A recombinant vaccinia virus expressing murine granulocyte-macrophage colony-stimulating factor (VVGM-CSF) was tested for its antitumor activity.Murine pulmonary metastasis was established by injecting 20×10~5 B16F10 melanoma cells into the tail vein of C57BL/6 mice. Three days after B16F10 inoculation,WGM-CSF or VVTK, a thymidine kinase gene deficient control vaccinia virus, were injected intraperitoneally twice weekly for 2 weeks. Two weeks later, the mice were sacrificed and pulmonary metastasis fool counted.The results demonstrated that VVGM-CSF treatment significantly decreased the number of pulmonary metastasis and prolonged the survival time of tumorbearing mice. Cytotoxic and phagocytic activities of the peritoncal macrophages were found to be markedly elevated in mice treated with WGM-CSF. Nitric oxide released from the macrophages was also found to be increased. These data, together with our other results,strongly demonstrated that continuous secretion of GMCSF and activation of macrophages might pal-tially explain the therapeutic effects of VVGM-CSF on murine pulmonary metastasis.

CO-EXPRESSION OF MACROPHAGE COLONY-STIMULATING FACTOR WITH ITS RECEPTOR IN HUMAN HEPATOMA CELLS AND ITS POTENTIAL ROLES

Objective: To investigate the potential role of macrophage colony-stimulating factor (M-CSF) and macrophage colony-stimulating factor receptor (M-CSF-R) on the growth of human hepatoma cells. Methods: Specimens of different origin, including tissues of human hepatocellular carcinoma (HCC), human fetal liver (FL) and normal liver (NL), the hepatoma cell lines, as well as the peripheral blood mononuclear cells (PBMC) from patients with HCC or liver metastatic tumor (LMT), were used to detect the expression levels of M-CSF and M-CSF-R by ABC immunohistochemistry staining and reverse transcription polymerase chain reaction methods the expression levels of M-CSF and M-CSF-R. Influence of monoclonal antibody against M-CSF (B5) or M-CSF-R (RE2) on proliferation ability of hepatoma cell linesin vitro was also studied. Results: The results showed that hepatoma tissues produced elevated levels of both M-CSF and M-CSF-R compared with those of fetal liver (P<0.001). The M-CSF/M-CSF-R expression levels of PBMC from hepatoma patients were higher than those of LMT patients (P<0.01,P<0.05) and the normal people (P<0.001). The hepatoma cell lines showed strong positive for M-CSF and M-CSF-R production. Both B5 and RE2 displayed a dose-dependent inhibitory effect on the growth and proliferation of hepatoma cells. Conclusion: The study indicates a co-expression model for M-CSF-R in hepatoma cells, suggesting an involvement of M-CSF/M-CSF-R in growth signaling of those malignant cells. The M-CSF/M-CSF-R seems to function through an autonomy mechanism in human hepatoma.

Granulocyte Colony-Stimulating Factor Enhances the Anticancer Effects of Cisplatin against Lung Cancer by Promoting Angiogenesis

The G-CSF is used as a therapeutic drug of the febrile neutropenia in lung cancer chemotherapy, however, there were few reports that showed the effects of combination effects of G-CSF and anticancer drugs against lung cancer. In the present study, we investigated the effects of G-CSF and the combination effects of G-CSF and cisplatin on lung cancer growth. We investigated the effect of G-CSF against the LL-2 and KLN-205 cells by MTT assay and tried to detect the G-CSF receptor by RT-PCR. Next, to analyze the G-CSF effects in vivo, we transplanted the LL-2 into C57BL/6 mice, intraperitoneally administered G-CSF (30 micro/kg/day) with or without cisplatin (5 mg/kg), measured the tumor size and analyzed pathologically by HE and immunostaining. In vitro analyses, G-CSF showed no effects in LL-2 and KLN-205 cells, and RT-PCR revealed no G-CSF receptor mRNA. In vivo analyses, G-CSF alone did not significantly suppress tumor growth. However, concurrent G-CSF administration with cisplatin significantly enhanced the tumor suppressing effect of cisplatin in early stage of tumor growth. The analysis data of vWF immunostaining indicated that the neovascularization in the peripheral region of the tumors was more enhanced in G-CSF treatment mice. ELISA assay revealed that G-CSF did not influence the serum concentration of TNF-alpha and IL-12 in tumor-bearing mice. This study suggests that concurrent (combination) administration of cisplatin with G-CSF is a safe and effective method for enhancing anticancer effects and reducing chemotherapeutic agent-induced myelosuppression.
