Rhizomes of Boesenbergia pandurata (Roxb.) Schlecht have been reported to contain active compounds with anticancer properties. This research was carried out to examine anti-proliferative and apoptotic induction against HeLa and Vero cells-line. Dried powder of B. pandurata rhizomes was extracted by a maceration method using 90% ethanol. Cytotoxic assays to determine $IC_{50}$ and anti-proliferative effects were carried out by MTT methods. Observation of apoptosis was achieved with double staining using acridine orange and ethidium bromide. The results showed that ethanolic extract of B. pandurata was more cytotoxic against HeLa cells ($IC_{50}$ of $60{\mu}g/mL$) than Vero cells ($IC_{50}$ of $125{\mu}g/mL$). The extract had higher anti-proliferative activity as well as apoptotic induction in HeLa than Vero cells. Therefore, it was concluded that the ethanolic extract of B. pandurata had anti-proliferative as well as apoptosis induction activity dependent on the cell type.

To compare functional Chinese cabbage('Amtak' baechu; F1 hybrid cultivar between Brassica rapa and B. perkinensis, AB) with general Chinese cabbage ('Chunkwang' baechu; general spring cultivar, CB), two kinds of kimchi(ABK and CBK) prepared with AB and CB cultivar were fermented at $10^{\circ}C$ for 10 days. Their fermentative characteristics and anti-proliferative activities against mouse carcinoma cell lines were investigated. General kimchi(CBK) showed mature pH on the $6^{th}$ day of fermentation, whereas functional kimchi(ABK) reached pH on the $9^{th}$ day. CBK also exhibited acidity of mature stage on the $6^{th}$ day, but ABK reached mature acidity on the $9^{th}$ day. Although ABK and CBK were salted in the same condition, ABK had lower salinity than CBK, throughout the fermentation time. The highest total bacterial and lactic bacterial counts of CBK showed on the $8^{th}$ day of fermentation, but ABK showed the highest total bacterial and lactic bacterial counts on the $10^{th}$ day. The texture of ABK was harder than CBK for fermentation time. This seems to be corrleated with the slower fermentation rate of ABK. ABK showed significantly higher anti-proliferative activity (54.6% cell viability of control) in B16BL6 at $1,000{\mu}g/mL$. ABK was also higher in anti-proliferative activity than CBK throughout the fermentation time. However, there was no significant difference in the anti-proliferative activity of ABK between the fermentation times. In conclusion, fermentation of ABK showed a better texture, due to the slow fermentation rate and more anti-proliferative activity against mouse carcinoma cell line than those of CBK.

Citrus macroptera (Rutaceae) has long been used in folk medicine in Bangladesh. Considering the folkloric context, this study was aimed to scrutinize anti-proliferative activity of C. macroptera fruit pulp juice (CMFPJ) against Ehrlich's ascites carcinoma (EAC). The anti-proliferative capacity of CMFPJ was investigated and confirmed primarily using MTT assay. In vivo anti-proliferative aptitude of CMFPJ was investigated with 25, 50, and 100 mg/kg/day intraperitoneal (i.p.) treatment. Anti-proliferative efficacy of CMFPJ was assessed based on EAC growth inhibition. CMFPJ inhibited EAC growth in vitro in a dose-dependent manner. And the percentages of in vivo EAC growth inhibition were 19.53, 49.2, and 68.9% at 25, 50, and 100 mg/kg CMFPJ respectively. CMFPJ significantly induced expression of apoptosis regulatory genes caspase-8, caspase-9, cytochrome-c, and caspase-3. This considerable anti-cancer activity was perhaps due to combinatorial effect of lectin, polyphenols, and flavonoids present in CMFPJ.

Purpose: This study was conducted to investigate the anti-proliferative effects of Ulmi Pumilae Cortex Extracts(UPCE) on MCF-7(human, breast, adenocaecinoma) and NIH3T3 (human, murine, fibroblast). Methods: MCF-7 cells and NIH3T3 cells were cultured and seeded in cell culture plates, respectively. UPC was extracted with hot water and then further fractionated it into five types: hexane, chloroform, ethyl acetate, butanol, and water soluable fractions. These five different fractions from UPCE were tested for their anti-proliferative effects on MCF-7 cells and NIH3T3 cells by MMT assay. Results: Among the five solvent-fractions of UPCE, n-hexane fraction and ethyl acetate fraction showed a strong anti-proliferative effects on MCF-7 cells but they displayed significant cytotoxicity on NIH3T3 cells, too. On the other hand, chloroform fraction showed a marked anti-proliferative effects on MCF-7 cells and low cytotoxicity on NIH3T3 cells. Conclusion: Chloloform fraction from UPCE showed selective anti-cancer activities on human breast cancer cell MCF-7 relatively to the other fractions.

A series of new 3-alkylamino-6-allylthio-pyridazine derivatives was synthesized through allythiolation and amino-de-halogenation and were expected to have anti-proliferative activity. 6-Allylthio-3-chloropyridazine was prepared from the reaction of 3,6-dichloropyridazine with allylmercaptan and sodium hydroxide. The alkylamines such as methylamine and the dialkylamines such as dimethylamine were introduced into the 3-position of the pyridazine ring. These new compounds showed anti-proliferative activities against MCF-7 human breast cancer cells in CCK-8 assays. These compounds are thus promising candidates for chemotherapy of breast cancer. Two compounds, 14 and 15, showed higher potencies for inhibiting growth of breast cancer cells than did 5FU. This suggests the potential anti-proliferative activity of these compounds.

Our aim was to explore anti-cell proliferative and anti-angiogenic potential of andrographolide by analyzing the expression pattern of cell proliferative (PCNA, Cyclin D1) and angiogenic (VEGF) markers during 7, 12-dimethylbenz(a)anthracene (DMBA) induced hamster buccal pouch carcinogenesis. DMBA painting three times a week for 14 weeks in the buccal pouch of golden Syrian hamsters resulted in oral tumors which were histopathologically diagnosed as well differentiated squamous cell carcinoma. Immunohistochemical (PCNA, VEGF) and RT-PCR (Cyclin D1) studies revealed over expression of PCNA, VEGF and Cyclin D1 in the buccal mucosa of hamsters treated with DMBA alone. Oral administration of andrographolide at a dose of 50 mg/kg bw to hamsters treated with DMBA not only suppressed the histological abnormalities but also down regulated the expression of PCNA, VEGF and Cyclin D1. The results of the present study suggest that andrographolide suppressed tumor formation in the buccal mucosa of hamsters treated with DMBA through its anti-cell proliferative and anti-angiogenic potential.

Treatment of oral cancers with chemotherapeutic agents become evaluated as an effective method to reduce cancer cell proliferation. Anti-proliferative and anti-oral cancer activities of momordin I on oral cancer cells were evaluated in this study. Momordin I was originally purified from a natural product, Ampelopsis radix and showed the antiproliferative activity against oral carcinoma, KB cells. Obtained $IC_{50}$ value was approximately $10.4{\mu}g/ml$. Time-and dose-dependent chromosomal DNA fragmentations were observed in momordin I-treated KB cells. Flow cytometry analysis showed time-dependent apoptotic cell appearance after treatment of momordin I. Approximately 18.6% apoptotic cells were observed at 72 hours after $20{\mu}g/ml$ of momordin I treatment. These observation were consistent with the results obtained in DNA fragmentation analysis. These data suggest that momordin I has anti-proliferative effect and induces cell death in KB cells through apoptosis.

Honokiol, a naturally occurring neolignan mainly found in Magnolia species, has exhibited a potential anti-proliferative activity in human cancer cells. However, the growth inhibitory activity against hepatocellular carcinoma cells and the underlying molecular mechanisms has been poorly determined. The present study was designed to examine the anti-proliferative effect of honokiol in SK-HEP-1 human hepatocellular cancer cells. Honokiol exerted anti-proliferative activity with cell-cycle arrest at the G0/G1 phase and sequential induction of apoptotic cell death. The cell-cycle arrest was well correlated with the down-regulation of checkpoint proteins including cyclin D1, cyclin A, cyclin E, CDK4, PCNA, retinoblastoma protein (Rb), and c-Myc. The increase of sub-G1 peak by the higher concentration of honokiol ($75{\mu}M$) was closely related to the induction of apoptosis, which was evidenced by decreased expression of Bcl-2, Bid, and caspase-9. Hohokiol was also found to attenuate the activation of signaling proteins in the Akt/mTOR and ERK pathways. These findings suggest that the anti-proliferative effect of honokiol was associated in part with the induction of cell-cycle arrest, apoptosis, and dow-nregulation of Akt/mTOR signaling pathways in human hepatocellular cancer cells.

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.
