  • In order to investigate the anticancer activity of an anti-yeast substance (AYS), a proteoglycan produced by Rhanella aquatilis AY2000, the cytotoxicity of the AYS against cancer cells was determined in vitro. The AYS was not cytotoxic to the human Jurkat T cell or the mouse sarcoma 180 cell, but was cytotoxic to the human colon cancer TH20 cell. The AYS was increasingly cytotoxic against human colon cancer cells in a dose-dependent manner at range from 62.5 to 500 ${\mu}g/ml$. Anticancer activity by combination of the AYS and an anticancer agent was also determined. The anticancer agent combined with the AYS was shown to possess greater synergistic anticancer activity against human colon cancer cells, as compared with the anticancer agent alone.

  • Cancer is the most deadly disease that causes the serious health problems, physical disabilities, mortalities, and morbidities around the world. It is the second leading cause of death all over the world. Although great advancement have been made in the treatment of cancer progression, still significant deficiencies and room for improvement remain. Chemotherapy produced a number of undesired and toxic side effects. Natural therapies, such as the use of plant-derived products in the treatment of cancer, may reduce adverse and toxic side effects. However, many plants exist that have shown very promising anticancer activities in vitro and in vivo but their active anticancer principle have yet to be evaluated. Combined efforts of botanist, pharmacologist and chemists are required to find new lead anticancer constituent to fight disease. This review will help researchers in the finding of new bioactive molecules as it will focus on various plants evaluated for anticancer properties in vitro and in vivo.

  • It is demonstrated that phenolic compound has cytotoxic effect on cancer cells. Recently, ferulic acid is involved in anticancer activity by showing the decrease of cell viability in cancer cells. But, the anticancer mechanism of ferulic acid is left unknown. The purpose of this study was to examine the anticancer activity of ferulic acid on NIH3T3 fibroblasts and human skin melanoma cells (SK-MEL-3). The anticancer activity was measured by determining the cytotoxicy of ferulic acid on these cells. The cytotoxicity was measured by cell viability via XTT assay in these cells. In this study, ferulic acid decreased cell viability according to the dose-dependent manners after human skin melanoma cells were treated with various concentrations of ferulic acid for 48 hours. especially, ferulic acid remarkably decreased cell viability at a concentration of $120{\mu}M$ compared with control in human skin melanoma cells. While, ferulic acid did not show the significant decrease of cell viability at concentrations of $30{\sim}120{\mu}M$ in NIH3T3 fibroblasts. These results suggest that ferulic acid showed anticancer activity in cancer cells such as human skin melanoma cells by the decrease of cell viability significantly.

  • This study identified the actual conditions for safe anticancer drug management among nurses and the relationship between level of awareness and performance of anticancer drug safety regulations in terms of preparation, administration, and disposal. The respondents were 236 nurses working with chemotherapy in wards and outpatient clinics in five hospitals in and near Seoul. Safety regulations provided for the anticancer drug the Occupational Safety Health Administration (OSHA, 1999), as modified for an earlier study, were used. The results showed that the level of awareness and performance on the anticancer drug safety regulations indicate their preparation ($3.38{\pm}0.55$, $2.38{\pm}0.98$), administration ($3.52{\pm}0.46$, $3.17{\pm}0.70$), general handling and disposal ($3.33{\pm}0.54$, $2.42{\pm}0.90$) on a scale 0 to 5. Also, there were significant differences in job positions, work experience, type of preparation, and continuing education and a positive relationship between the level of awareness and nursing performance. Thus, nurses should receive continuing education on the handling of anticancer drugs to improve the level of performance following safety regulations.

  • Anticancer effect of methanol extract of Caesalpinia sappan L. on oral carcinoma (KB) and osteosarcoma (HOS) cells were investigated in this study. In order to elucidate the anticancer mechanism of Caesalpinia sappan L, we analyzed telomerase inhibitory effect of the methanol extract of Caesalpinia sappan L. In addition we prepared 5 fraction samples according to its polarity differences and analyzed anticancer effects on oral carcinoma and osteosarcoma cells. Following results are obtained in this study. 1. 50% cell proliferation inhibitory value ($IC_{50}$) of the methanol extract of Caesalpinia sappan L. against oral carcinoma (KB) cells and osteosarcoma (HOS) cells were $9.0{\mu}g/ml$ and $10.9{\mu}g/ml$, respectively. 2. The methanol extract of Caesalpinia sappan L. showed inhibitory effect of telomerase which is required for cancer cell immortality. Therefore, it seems that the anticancer effect of methanol extract of Caesalpinia sappan is at least partially due to telomerase inhibitory effect. 3. Five fraction samples were prepared according to its polarity and 88.7% of ingredient of total methanol extract was transferred to ethylacetate fraction. Thin layer chromatography analysis showed that dichloromethane fraction contained ingredient with relatively high polarity and ethylacetate fraction contained similar ingredient found in total methanol extract. 4. Anticancer effect was observed in n-hexane, dichloromethane, and ethylacetate fractions. The highest anticancer effect was found in dichloromethane fraction which had $IC_{50}$ value of 4.4 and $>4.0{\mu}g/ml$ against oral carcinoma (KB) cells and osteosarcoma (HOS) cells, respectively.

  • The identification of tumor antigens is essential for the development of anticancer therapeutic vaccines and clinical diagnosis of cancer. SEREX (serological analysis of recombinant cDNA expression libraries) has been used to identify such tumor antigens by screening sera of patients with cDNA expression libraries. SEREX-defined antigens provide markers for the diagnosis of cancers. Potential diagnostic values of these SEREX-defined antigens have been evaluated. SEREX is also a powerful method for the development of anticancer therapeutics. The development of anticancer vaccines requires that tumor antigens can elicit antigen-specific antibodies or T lymphocytes. More than 2,000 antigens have been discovered by SEFEX. Peptides derived from some of these antigens have been evaluated in clinical trials. This review provides information on the application of SEREX for identification of tumor-associated antigens (TAA) for the development of cancer diagnostics and anticancer therapeutics.

  • Cytotoxic test was performed by SRB assay on human epidermoid carcinoma HEp-2 cell line for screening the soil microorganism, secreting anticancer agent. One microorganism was selected among two thousand microorganisms for its highest cytotoxicity. And this microorganism was identified with Streptomyces species after performing of diaminopimeric acid and reducing sugar analysis of cell wall and analysing the cultural characteristics and named Streptomyces sp. SM 1119. The effect of anticancer agent in SM 1119 culture extract on the cell cycle was studied by using GG$_{o}$ synchronized NIH 3T3 cells. The extract inhibited the serum stimulation of GG$_{o}$ NIH 3T3 cell only within 1 hour after serum stimulation but not after 6 hours. The extract also reduced the amount of c-myc mRNA in Colo 320 cell. These results suggest that the anticancer agent in the extract inhibits the progression of cell cycle very early stages, probably from G$_{0}$ to G$_{1}$.

  • Lipiodol-anticancer suspensions containing fluorouracil, tegafur, mitomycin C, methotrexate, or adriamycin were prepared by Shinohara method using aluminum monostearate as a dispersing stabilizer. Lipiodol-suspension showed thixotropic property when the concentration of aluminum monostearate was above 2%. Observed thixotropic area which reflects the extent of thixotropic breakdown indicated that the thixotropic property of Lipiodol-suspensions maintained for six weeks in a refrigerator$(4^{\circ}C)$. Lipiodol-anticancer suspensions containing 2% aluminum monostearate maintained a more stable suspension system compared with simple mixtures and Lipiodol-anticancer suspensions without aluminum monostearate. As the concentration of aluminum monostearate increased, the drug release from Lipiodol-anticancer suspensions was more retarded.
