the high metastatic growth potential of LNM35 cells. Consistent with previous microarray analysis data, neither tumor necrosis factor-a nor macrophage-colony-stimulating factor expression was detected in our microarray analyses of LNM35 and N15 cells. By contrast, the mRNA levels of the inflammatory cytokines IL-1a and IL-1b were much higher in LNM35 cells. The in vitro expression of human IL-1a, measured by ELISA, was also about 20-fold higher in the highly metastatic cells . IL-1b protein expression was not detectable by either ELISA or western blotting, while expression of the chemokines CXCL1/Groa, CXCL5/ENA-78, CXCL8/IL-8, and IL-6 was three- to five-fold higher and that of VEGF-C was 1.4-fold higher in LNM35 cells than in N15 cells . By contrast, there was no difference in the cellular VEGF-A levels between the two cell lines, and CCL2/MCP-1, a representative CC chemokine, was not detectable in either cell line by ELISA. Western blot analysis showed markedly higher IL-1a expression by the highly metastatic Oritavancin (diphosphate) chemical information cancer cells, while IL1RI expression in the two cell lines was similar. Results Highly metastatic cancer cells show enhanced macrophage and neutrophil infiltration and lymph node metastasis in vivo The highly metastatic cancer cell line NCI-H460-LNM35 and its lower metastatic counterpart NCI-H460-N15 were originally established from metastatic foci in lymph nodes of mice after subcutaneous injection of cells from the human lung cancer cell line NCI-H460. Under basal growth conditions, the two cell lines have similar proliferation rates, with a doubling time of,16 h. However, in an in vivo xenograft model, their tumor growth rates differed markedly. Therefore, we used these two cell lines as a model system to compare the angiogenesis, lymphangiogenesis, macrophage and neutrophil infiltration, and lymph node weight in the respective tumors evaluated at 35 days after subcutaneous injection of these cells. IHC analysis revealed important differences between N15 and LNM35 tumors in the development of hemangiogenic microvessels and lymphatic vessels, and the extent of macrophage and neutrophil infiltration. Quantitative analyses confirmed that the angiogenesis, lymphangiogenesis, and macrophage and neutrophil infiltration were significantly greater in the LNM35 tumors. 13679187 target=_blank”>17594192 Consistent with these findings, the lymph nodes of mice bearing LNM35 tumors were more than three-fold larger and heavier than the lymph nodes of mice bearing N15 tumors and comprised human cancer cells, stromal cells, and lymphatic vessels. Furthermore, the incidence of lymph node metastasis was increased in all mice with subcutaneous implantations of LNM35 cells, compared with mice implanted with N15 cells. The lymph nodes of the LNM35implanted mice were almost completely occupied by cancer cells. Expression of IL-1, CXCL8/IL-8, and VEGF family proteins is enhanced in highly metastatic cancer cells and tumor macrophages in vivo We then measured the expression of IL-1 proteins, CXCL8/IL-8, and VEGF family proteins Antitumor effect of Cl2MDP-LIP on tumor growth by LNM35 xenografts. Mice were subcutaneously inoculated with LNM35 cells at day 0, and tumor growth was followed until day 35 in animals intravenously injected twice weekly with PBS-LIP or Cl2MDP-LIP. p,0.05 between PBS-LIP and Cl2MDPLIP-treated groups.
