In humic substances, fulvic acid (FA) is a subclass of diverse compounds known as humic substances, which are by-products of organic degradation from microorganisms. FA can suppress the proliferation of tumor cells. Despite numerous studies, the exact mechanism for the various effects of FA is not clearly understood. Based on results demonstrating anti-proliferation effects on human cancer, we investigated whether FA has similar effects on lung cancer in this study. Firstly, the anti-cancer effect of FA in pulmonary epithelial tumor cell lines (TC-1 cells) was examined by confirming its inhibitory effect on the cell proliferation of TC-1 cells. TC-1 cell proliferation was reduced by FA on a dose-dependent and time-dependent manner. After 24 hours of FA treatment, cell morphological changes such as cell volume decrease, non-adherence and increased number of apoptotic cells were clearly observed. In addition, FA induced a DNA ladder pattern by increased of DNA fragments in TC-1 cells. In the intracellular regulatory pathway by FA, we confirmed that FA induced the reduction of the anti-apoptotic protein, Bcl-2 protein levels. These results indicate that FA has anticancer effect by inducing intracellular apoptotic pathway. Further research on the mechanism of anticancer effects will be basic data for the development of potential anticancer drugs.

Objectives : This study was carried out to investigate the inhibitive effects of cotton plant sectional extracts in cancer cell lines, Calu-6(human, Caucasian, lung, adenocarcinoma) and MCF-7(human, Caucasian, breast, adenocarcinoma). The incidence of cancer has been increasing even in korea due to the change of dietary life and westernization and becoming conspicuous as the disease threatening health. But cancer treatment have not been fully effective against the high incidence or low survival rate of most cancer. Methods : Calu-6 and MCF-7 cells were cultured and seeded in cell culture plates, respectively. And sectional extracts of cotton plant were treated to MCF-7 cells. Results and Conclusion : Sectional extracts of cotton plant showed no anti-proliferative effect on MCF-7 cells, but root and stem extracts showed strong anti-proliferative effects on Calu-6 cells. Fruit, leaf and flower extracts also showed anti-proliferative effects on Calu-6 cells but not so much like root and stem extracts. But seed extract showed no anti-proliferative effect on Calu-6 cells.

Kaempferol, a component of Polygonati rhizoma, is one of the herbal flavonoids, which is used in therapeutic agent for anti-hypercholesterol, anti-hypertension and anti-diabetes. And it is also known to be effective in anti-cancer therapy for breast, prostate and other type of cancers. However, the anti-cancer therapeutic mechanisms are pooly understood. To address molecular mechanism underlying kaempferol-induced anti-cancer effects, we determined the effect of kaempferol on cell growth of the lung cancer cell lines, A549, H1299 and H460. From the FACS analysis, measurement of caspase activity, DAPI and tryptophan blue staining, and DNA fragmentation assay, we found that kaempferol induces apoptosis and H460 cells are most sensitive among the tested cell lines. In addition, we performed microarray to identify the genome-wide expression profiling regulated by kaempferol. Lots of cell cycle-related genes were under-expressed, whereas the genes related to TGF-beta/SMAD pathway were over-expressed in kaempferol-treated H460 cells. Additionally, kaempferol also increased expression levels of apoptosis related genes such as death receptors, FAS, TRAIL-R and TNF-R, and casepase-8 and caspase-10. Overall, our results suggest that kaempferol promotes anti-lung cancer therapeutic effects by inducing G1 arrest and apoptosis through TGF-beta/SMAD pathway and death receptors/caspase pathway, respectively.

Objectives : The aim of this study was to verify anti-cancer and anti-oxidant efficacies of Korean wild ginseng and cultivated wild ginseng of Korea and China. Methods : For the measurement of anti-oxidation, SOD-like activity was evaluated using xanthine oxidase reduction method under in vitro environment. Subcutaneous and abdominal cancer were induced using CT-26 human colon cancer cells for the measurement of growth inhibition of cancer cells and differences in survival rate. Results : 1. Measurement of anti-oxidant activity of ginseng, Chinese and Korean cultivated wild ginseng, and natural wild ginseng samples showed concentration dependent anti-oxidant activity in HX/XOD system. Anti-oxidant activity showed drastic increase at 1mg/ml in all samples. 2. For the evaluation of growth inhibition of cancer cells after hypodermic implantation of CT-26 cancer cells in the peritoneal cavity of mice, Chinese and Korean cultivated wild ginseng and natural wild ginseng groups showed significant inhibition of tumor growth from the 12th day compared to the control group. Similar inhibitory effects were also shown on the 15th and 18th days. But there was no significant difference between the experiment groups. 3. For the observation of increase in survival rate of the natural wild ginseng group, CT-26 cancer cells were implanted in the peritoneal cavity of mice.

Doenjang is a major fermented soy-based food in Korea. Recent investigations have shown that fermented soybean foods have immunity-enhancing, anti-cancer, anti-obesity and anti-diabetic effects. Several studies also have reported that genistein and daidzein, which are easily absorbed in the body are produced in larger quantities in aged doenjang. The purpose of this study was to evaluate the variations in the anti-cancer effects of commercialized doenjang as it ages. Four groups were formed for this study according to aging periods of doenjang, namely short (under 5 years, S group), mid (under 10 years, M group), long (under 15 years, L group) and very long (over 15 years, E group). The anti-cancer effects of doenjang were determined by cell cytotoxicity assays in A549, YAC-1, and HepG2 cancer cell lines. Also, NK cell activity and splenocyte proliferation were assayed for cancer immunotherapy. The quantities of phenolic compounds in doenjang at different ages were also measured. The results showed that the anti-cancer effects increased in the S and M groups for all three cancer cell lines. Interestingly, similar to this result, splenocyte proliferation and NK activity were also the highest in the S and M groups. In contrast, the E group showed significantly reduced splenocyte proliferation. The quantity of phenolic compounds was similar to that of the anti-cancer results. Collectively, these results suggest that the fermentation period of doenjang plays a very important role in determining its anti-cancer effects.

This study was designed to investigate the anti-tumor effects of fresh carrot juice, methanol-extracts, and $\beta$-carotene on the human lung cancer cell line NCI-H1299. The anti-tumor effect was evaluated by the MTT assay in vitro. The anti-tumor effect of fresh carrot juice against NCI-H1299 lasted up to 96 hours after exposure; the viability rate of lung cancer cells decreased below 50% after 48 hours, and further after 72 hours. The strongest propagation inhibition effect of fresh carrot juice was shown at the concentration of 2000 $\mu\textrm{g}$/$m\ell$ after 72 hours and the viability rates was 45.98% even at the concentration of 25 $\mu\textrm{g}$/$m\ell$. The value of $IC_{50}$/ was 23.1$\mu\textrm{g}$/$m\ell$ when the elapsed time was 72 hours. The viability rate of methanol-extract was 52.4% under the concentration of 2000 $\mu\textrm{g}$/$m\ell$ and the elapsed time of 72 hours. Under the concentration of 1000 $\mu\textrm{g}$/$m\ell$ and the elapsed time of 48 hours, $\beta$ -carotene decreased the viability rate to 29.99%. The $IC_{50}$/ value of $\beta$-carotene was 691.2$\mu\textrm{g}$/$m\ell$ after 72 hours. According to the above results, the anti-tumor effect arose in NCI-H1299 when the concentration of the fresh carrot juice or the $\beta$-carotene was more than 25 $\mu\textrm{g}$/$m\ell$ or 1000 $\mu\textrm{g}$/$m\ell$, respectively. On the other hand, the methanol-extracts showed a weak anti-tumor effect even at a concentration as high as 2000 $\mu\textrm{g}$/$m\ell$.

At once Medicine of East and West have the same purpose in treating, but there is a difference between the method of medical care and the view/slant on a disease each other. In the East Medicine, It is very difficult to explain the concept of Hwalhyulhwau but it is one of the way to cure cancer for long time. Be based on the theory of the East Medicine, research single medicine's anti-cancer effect among the natural products that has anti-cancer function. Moreover, for the purpose of finding new way to cure and prevent against cancer, we, the researchers, divided into four groups for this research: Group one: survey new substance with anti-cancer effects from natural products. Group two: research of anti-cancer mechanism through the experimental studies. Group three: research of immune responses in anti-canncer effects from natural products. Group four: research of the inhibitory effect on metastasis through the anti-angiogenesis. From the above results, we blended efficacious medidcines against cancer and made new prescriptions of Soam-I and Soam-II. Now, we are studying on these new prescriptions. We speculate that Soam-I and Soam-II may be used for a new conceptional anticancer therapy.
