  • Objectives : This study was performed to examine the anticancer effect of mountain ginseng Pharmacopuncture(MGP) to the nude mouse of lung carcinoma induced by NCI-H460 human nonsmall lung cancer cells. Methods : Human lung cancer (NCI-H460) cells were cultured and applied to evaluate anti-tumor activity in nude mice. After confirmed tumor growth in mice, MGP was treated per 0.1ml/kg dose to intraperitoneal and intravenous injection everyday for four weeks. And checked the changes in body weights, tumor volume, mean survival time and percent, increase in life span, histo-pathological findings, organ weights, and blood chemistry levels. Results : The results of in vivo study showed that MGP may have potential as growth inhibitor of solid tumor induced NCI-H460 without marked side effects. MGP inhibited dosage-dependently the growth of NCI-H460 cell-transplanted solid tumor compared with the control group. And mean survival time of MGP treated group was prolonged comparing with control group. Generally the group of intravenous injection is more effective than intraperitoneal injection. Conclusion : These results were suggested that MGP may be a useful anticancer agent for therapy of human lung cancer. And follow study need for the certain evidence.

  • Background : Anticancer effects of herbal medicine have been reported in various types of cancer, but the systematic approaches to explain molecular mechanism(s) are not established yet. Objective : The purpose of this study is to investigate the apoptotic cell death by Egg White combined Chalcanthite in NCI-H460 human lung cancer cells. Methods : Inhibitory effects were estimated by the MTT-assay. Cancer cells were stained with DAPI and showed condensed and fragmented nuclei. The expression of cleaved caspase-3, bcl-2, and bax was detected by western blotting. To establish a basis of understanding for anti-cancer mechanism, whole proteins have been obtained from NCI-H460 harvested at 24 hrs after the treatment of Egg White combined Chalcanthite, protein expression has been profiled by 2DE-based proteomic approach. Results : NCI-H460 human lung cancer cells were treated by three samples of IS3, IS4 and IS5. IS4 inhibited most effectively the growth of NCI-H460 human lung cancer cells. The expression of cleaved caspase-3 increased in IS4 in a concentration-dependent manner. Various changes of the protein expression have been monitored, and most frequent dysregulation was found in Vimentin, Lamin-A/C. Conclusion : Egg White combined-Chacanthite inhibited the growth of NCI-H460 human lung cancer cells by inducing the apoptotic cell death via caspase-3 activation. Based upon the present findings, the further study will focus on monitoring various cancer survival factors after artificial regulation of the proteins identified, and it would be the basis for the understanding of the Chacabthite anticancer effect(s) at the molecular level.

  • Objectives : I investigated whether bee venom inhibit cell growth through enhancement of death receptor expressions in the human lung cancer cells, NCI-H460. Methods : Bee venom(1-5 ${\mu}g/ml$) inhibited the growth of NCI-H460 lung cancer cells by the induction of apoptotic cell death in a dose dependent manner. Results : Consistent with apoptotic cell death, expression of TNF-R1, TNF-R2, FAS, death receptors(DR) 3, 4, 5 and 6 was increased in the cells. Expression of DR downstream pro-apoptotic proteins including Caspase-8, -3, -9 was upregulated and Bax was concomitantly overwhelmed the expression of Bcl-2. NF-kB were inhibited by treatment with bee venom in NCI-H460 cells through TNF response change led by TNF-R1 and TNF-R2. Conclusions : These results suggest that bee venom should exert anti-tumor effect through induction of apoptotic cell death in NCI-H460 human lung cancer cells via enhancement of death receptor expression, and that bee venom could be a promising agent for preventing and treating lung cancer.

  • Tumor growth and metastasis are dependent on angiogenesis, and endothelial cell invasion and migration are apparent means of regulating tumor progression. We report here that saxatilin, a snake venom-derived disintegrin, suppresses the angiogenesis-inducing properties of NCI-H460 human lung cancer cells. Culture supernatants of NCI-H460 cells are able to induce human umbilical vascular endothelial cell (HUVEC) invasion and tube formation. However, treatment of the cancer cells with saxatilin resulted in reduced angiogenic activity of the culture supernatant. This suppressed angiogenic property was found to be associated with the level of vascular endothelial growth factor (VEGF) in the culture supernatant. Further experimental evidence indicated that saxatilin inhibits VEGF production in NCI-H460 cells by affecting hypoxia induced factor-1$\alpha$ (HIF-1$\alpha$) expression via the Akt pathway.

  • Objectives : I investigated whether Bee Venom can synergistically strengthen the cytotoxic effects of NK-92 cells, enhancing the inhibition of the growth of Lung Cancer Cells including A549 and NCI-H460 through induction of death receptor dependent extrinsic apoptosis and NO generation in the Nitro-oxide pathway. Methods : Bee Venom inhibited cell proliferation of A549 or NCI-H460 Human Lung Cancer Cells as well as NK-92 Cells. Moreover, when they were co-punctured with NK cells and concomitantly treated by 3 ${\mu}g/ml$ of Bee Venom, more influence was exerted on inhibition of proliferation of A549 or NCI-H460 Human Lung Cancer Cells than BV or NK cell co-culture alone. Results : The expression of Fas, TNFR2, DR3, DR6 in A549 Lung Cancer Cells was significantly increased by co-culture of NK-92 cells and treatment of 3 ${\mu}g/ml$ of Bee Venom, compared to co-culture of NK-92 cells alone, whereas the expression of Fas, TNFR2, DR6 in NCI-H460 Lung Cancer Cells was significantly increased by co-culture of NK-92 cells, representing no synergistic effects in the co-culture of NK-92 cell and concomitant treatment of 3 ${\mu}g/ml$ of Bee Venom. Coincidently, caspase-8, a expression of pro-apoptotic proteins in the extrinsic apoptosis pathway demonstrated same results as the above. Meanwhile, In NO generation, there is little change of NO generation in co-culture of NK-92 cells with A549 cells as well as the co-culture of NK-92 cell with them and concomitant treatment of 3 ${\mu}g/ml$ of Bee Venom, whereas increase of NO generation was shown in co-culture of NK-92 cells with NCI-H460 cells as well as the co-culture of NK-92 cell with them and concomitant treatment of 3 ${\mu}g/ml$ of Bee Venom, although synergistic effects by Bee Venom was not found. Conclusions : These present data provide that Bee Venom could be useful candidate compounds to enhance lung cancer growth inhibiting ability of NK-92 cells through DR expression and the related apoptosis.

  • Objectives : This study was designed to investigate the antiproliferative activity of the water extract of Samgibopae-tang (SGBPT) in NCI-H460 and A549 non-small-cell lung cancer cell lines Methods : In this study, we measured the subsistence, form of NCI-H460 and A549 non-small-cell lung cancer cell by hemocytometer and DAPI staining. In each cell, we analyzed DNA fragmentation. reverse transcription-polymerase chain reaction and measured activity of caspase-3, caspase-8 and caspase-9. Results and Conclusions : We found that exposure of A549 cells to SGBPT resulted in growth inhibition in a dose-dependent manner. butSGBPT did not affect the growth of NCI-H460 cells. The antiproliferative effect by SGBPT treatment in A549 cells was associated with morphological changes. SGBPT treatment partially induced the expression of DR5 cells and the expression of Faswas markedly increased in both transcriptional and translational levels in A549 cells. SGBPT treatment partially induced the expression of Bcl-2, Bcl-XL and the expression of Bid was markedly decreased in translational levels in A549 cells. However, SGBPT treatment did not affect the expression of IAP family in A549 orNCI-H460 cells. SGBPT treatment partially induced the expression of caspase-3, caspase-8, caspase-9 activity which markedly increased in a dose-dependent manners in A549 cells. The fragmental development of PARP and ${\beta}$-catenin protein was observed in A549 cells by SGBPT treatment. SGBPT treatment induced the expression of PLC-${\gamma}1$ protein which decreased in A549 cells. SGBPT treatment partially induced the expression of DFF45/ICAD which markedly increased in a dose-dependent manner in A549 cells. Taken together. these findings suggested that SGBPT-induced inhibition of human lung carcinoma did not affect NCI-H460 cell growth. However, SGBPT-induced inhibition of human lung carcinoma A549 cell growth was associated with the induction of death receptor and mitochondrial pathway. The results provided important new insights into the possible molecular mechanisms of the anti-cancer activity of SGBPT.

  • Human NK cells, identified 30 years ago based on their ability to spontaneously kill tumor cells, constitute a subset of lymphocytes, which play an important role in the first line of immune defense and the effective function of these cells are enhanced by cytokines. Lung carcinoma has been one of the most commonly diagonosed cancer as well as the leading cause of cancer death in male. Here we provide the evidence that human natural killer cells has inhibitory effects on tumor growth of human lung cancer cell NCI-H460 (non-small cell lung cancer). Enriched NK cell population was obtained by 2 weeks cultivation in interleukin-2(IL-2)-containing medium. The resulting population comprised 26% CD3$^+$ cells, 9% CD3$^+$CD4$^+$ cells, 16% CD3$^+$CD8$^+$ cells, 76% CD56$^+$ cells, 6% CD3$^+$CD56$^+$ cells and 70% CD3$^-$CD56$^+$ cells. Activated NK cells at doese of 2.5, 5, and 10 million cells per mouse inhibited 2%, 12% and 45% of NCI-H460-induced tumor growth in nude mouse xenograft assays, repectively. This result suggests that NK cell-based immunotherapy may be used as an adoptive immunotherapy for lung cancer patients.

  • Ceramides are well-known second messengers that induce apoptosis in various kinds of cancer cells, and their effects are closely related to radiation sensitivity. Phytoceramides, the yeast counterparts of the mammalian ceramides, are also reported to induce apoptosis. We investigated the effect of a novel ceramide derivative, N-acetylphytosphingosine (NAPS), on the radiosensitivity of NCI-H460 human lung carcinoma cells and its differential cytotoxicity in tumor and normal cells. The combination of NAPS with radiation significantly increased clonogenic cell death and caspase-dependent apoptosis. The combined treatment greatly increased Bax expression and Bid cleavage, but not Bcl-2 expression. However, there was no effect on radiosensitivity and apoptosis in BEAS2B cells, which derive from normal human bronchial epithelium. Cell proliferation and DNA synthesis were significantly inhibited by NAPS in both NCI-H460 and BEAS2B cells, but only the BEAS2B cells recovered by 48h after removal of the NAPS. Furthermore, the NCI-H460 cells underwent more DNA fragmentation than the BEAS2B cells in response to NAPS. Our results indicate that NAPS may be a potential radiosensitizing agent with differential effects on tumor vs. normal cells.

  • Objective : This study was designed to investigate the effect of the water extract of Gamisamgibopae-tang(GMSGBPT), an oriental herbal formulation, on the growth of NCI-H460 and A549 human non-small-cell lung cancer cell lines. Methods : Cytotoxicity and cell morphology were evaluated by MTT assay and inverted microscope, respectively. Apoptosis was detected using agarose gel electrophoresis and flow cytometer. The expression levels of mRNAs and proteins of target genes were determined by RT-PCR and western blot analyses, respectively Result and Conclusion : We found that exposure of A549 cells to GMSGBPT resulted in the growth inhibition in a dose-dependent manner as measured by MTT assay, but GMSGBPTdid not affect the growth of NCI-H460 cells. The anti-proliferative effect of GMSGBPT treatment in A549 cells was associated with morphological changes, formation of apoptotic bodies and DNA fragmentation, and flow cytometry analysis confirmed that GMSGBPT treatment increased the populations of apoptotic-sub G1 phase. Growth inhibition and apoptotic cell death by GMSGBPT were connected with a up-regulation of cyclin-dependent kinase inhibitor p21 (WAF1/CIP1) mRNA and protein in a tumor suppressor p53-independent fashion. However GMSGBPT treatment did not affect other growth regulation-related genes such as early growth response-1 (Egr-1), nonsteroidal anti-inflammatory drug (NSAID)-activated gene-1 (NAG-1), inducible nitric oxide synthase (iNOS), cyclooxygenases (COXs), telomere-regulatory factors in A549 orNCI-H460 cells. Taken together, these findings partially provide novel insights into the possible molecular mechanism of the anti-cancer activity of GMSGBPT.

  • In the present study, we investigated the antiproliferative activity of the water extract of Samgibopae-tang (SGBPT) in NCI-H460 and A549 non-small-cell lung cancer cell lines. We found that exposure of A549 cells to SGBPT resulted in the growth inhibition in a dose-dependent manner as measured by MTT assay, however SGBPT did not affect the growth of NCI-H460 cells. The antiproliferative effect by SGBPT treatment in A549 cells was associated with morphological changes such as membrane shrinking and cell rounding up. SGBPT treatment did not induce the cell cycle arrest in both cell lines, however the frequency of sub-G1 population was concentration-dependently increased by SGBPT treatment in A549 cells. SGBPT treatment partially induced the expression of tumor suppressor p53 in A549 cells and the expression of cyclin-dependent kinase inhibitor p21(WAF1/CIP1) was markedly increased in both transcriptional and translational levels in A549 cells. The up-regulation of p21 by SGBPT occurred in a similar a concentration dependent manner to that observed with the inhibition of cell viability and induction of sub-G1 population of the cell cycle. However SGBPT treatment did not affect other growth regulation-related genes such as early growth response-1 (Egr-1), nonsteroidal anti-inflammatory drug-activated gene-1 (NAG-1), inducible nitric oxide synthease (iNOS), cyclooxygenases (COXs), telomere-regulatory factors in A549 as well as NCI-H460 cells. Taken together, these findings suggested that SGBPT-induced inhibition of human lung carcinoma A549 cell growth was aoosciated with the induction of p21 and the results provided important new insights into the possible molecular mechanisms of the anti-cancer activity of SGBPT.
