SKOV3/neo group was used as control group and the rest groups were experimental groups. We injected GCV
75 mg/kg·d intraperitoneally for 5 days after tumor transplantation, then, observed the biologic characteristics of SCID, such as spirit, appetite and abdominal bulge. The survival periods of 4 SCID mice selected randomly from each groups were recorded from being successfully transplanted human ovarian carcinoma {Selleck Anti-diabetic Compound Library|Selleck Antidiabetic Compound Library|Selleck Anti-diabetic Compound Library|Selleck Antidiabetic Compound Library|Selleckchem Anti-diabetic Compound Library|Selleckchem Antidiabetic Compound Library|Selleckchem Anti-diabetic Compound Library|Selleckchem Antidiabetic Compound Library|Anti-diabetic Compound Library|Antidiabetic Compound Library|Anti-diabetic Compound Library|Antidiabetic Compound Library|Anti-diabetic Compound Library|Antidiabetic Compound Library|Anti-diabetic Compound Library|Antidiabetic Compound Library|Anti-diabetic Compound Library|Antidiabetic Compound Library|Anti-diabetic Compound Library|Antidiabetic Compound Library|Anti-diabetic Compound Library|Antidiabetic Compound Library|Anti-diabetic Compound Library|Antidiabetic Compound Library|Anti-diabetic Compound Library|Antidiabetic Compound Library|buy Anti-diabetic Compound Library|Anti-diabetic Compound Library ic50|Anti-diabetic Compound Library price|Anti-diabetic Compound Library cost|Anti-diabetic Compound Library solubility dmso|Anti-diabetic Compound Library purchase|Anti-diabetic Compound Library manufacturer|Anti-diabetic Compound Library research buy|Anti-diabetic Compound Library order|Anti-diabetic Compound Library mouse|Anti-diabetic Compound Library chemical structure|Anti-diabetic Compound Library mw|Anti-diabetic Compound Library molecular weight|Anti-diabetic Compound Library datasheet|Anti-diabetic Compound Library supplier|Anti-diabetic Compound Library in vitro|Anti-diabetic Compound Library cell line|Anti-diabetic Compound Library concentration|Anti-diabetic Compound Library nmr|Anti-diabetic Compound Library in vivo|Anti-diabetic Compound Library clinical trial|Anti-diabetic Compound Library cell assay|Anti-diabetic Compound Library screening|Anti-diabetic Compound Library high throughput|buy Antidiabetic Compound Library|Antidiabetic Compound Library ic50|Antidiabetic Compound Library price|Antidiabetic Compound Library cost|Antidiabetic Compound Library solubility dmso|Antidiabetic Compound Library purchase|Antidiabetic Compound Library manufacturer|Antidiabetic Compound Library research buy|Antidiabetic Compound Library order|Antidiabetic Compound Library chemical structure|Antidiabetic Compound Library datasheet|Antidiabetic Compound Library supplier|Antidiabetic Compound Library in vitro|Antidiabetic Compound Library cell line|Antidiabetic Compound Library concentration|Antidiabetic Compound Library clinical trial|Antidiabetic Compound Library cell assay|Antidiabetic Compound Library screening|Antidiabetic Compound Library high throughput|Anti-diabetic Compound high throughput screening| cells to natural death. The rest 6 SCID mice of each groups were sacrificed as soon as the appearance of death in the control group. The number of macrophages infiltrated the tumor sites was examined by flow cytometry. Briefly, monoplast suspension of tumor tissue was prepared by trituration. Cells were re-suspended in PBS at the density of 1 × 106 cells/ml followed by addition of 10 μl human CD14/PE (Pharmingen USA) antibody mixing thoroughly. After 30 min of activation away from light at 20°C-25°C, flow cytometry was
used to detect the amount of macrophages. The TNF-α protein level was analysised by western blot. The cell apoptosis rate, cell cycle and the expression of BIX 1294 solubility dmso CD25 (IL-2R) and CD44v6 in tumor cells were detected by flow cytometer. Statistical analysis The SPSS version 13.0 software was used for statistical analysis. Results were reported as means ± standard deviation (SD). The statistical differences between group was assessed by q test. Kaplan-Meier survival curves were generated with the use of SPSS 13.0. Comparisons of median survivals were performed using log-rank tests. Alpha (α) level was set at 0.05. Results Confirmation of plasmid Restriction enzyme analysis of plasmid DNA showed that tk and MCP-1 gene fragment were inserted in the proper many orientation in the vector of pLXSN named pLXSN/tk-MCP-1, so had pLXSN/tk, pLXSN/MCP-1 and pLXSN/neo (Figure 1-B). Packaging and transfection of pLXSN/tk, pLXSN/MCP-1, pLXSN/tk-MCP-1 and pLXSN recombinantretroviral vector The recombinant retroviral vectors including pLXSN/tk, pLXSN/MCP-1,
pLXSN/tk-MCP-1 and pLXSN/neo, were transfected into retroviral packaging cell line PA317 by DOTAP, respectively. Stable retroviral vector-produced lines were generated by expanding the G418-resistant (> 500 μg/ml) colonies, named PA317/tk (pLXSN/tk transferred), PA317/MCP-1 (pLXSN/MCP-1 transferred), PA317/tk-MCP-1(pLXSN/tk- MCP-1 transferred) and PA317/neo (pLXSN transferred) respectively. The supernatant containing the packaged retroviruses was Selleckchem CX 5461 harvested, filtered and titrated 4.5 × 105 CFU/ml-6.0 × 105 CFU/ml determined in NIH3T3 cells. SKOV3 cells were infected with the high titre recombinant retrovirus (pLXSN/tk, pLXSN/MCP-1, pLXSN/tk-MCP-1 and pLXSN/neo), while SKOV3 tansfected pLXSN/neo was used as the control group. Stable retroviral vector-produced cell lines were generated by expanding the G418-resistant (600 μg/ml) colonies, named SKOV3/neo, SKOV3/tk, SKOV3/MCP-1 and SKOV3/tk-MCP-1 respectively.
