  • Delphinidin, an aglycone form of anthocyanins, was demonstrated to have anti-carcinogenic potential. The compound at $50\;{\mu}g/mL$ caused a significant increase of quinone reductase activity, an anti-carcinogenic marker enzyme, in mouse hepatoma cell lines (Hepa1c1c7 and BPRc1). Delphinidin enhanced the expression of other detoxifying or antioxidant enzymes including glutathione s-transferase, gamma-glutamylcysteine synthetase, heme oxygenase 1, and glutathione reductase. It suppressed the proliferation of murine hepatoma cells in a dose-dependent manner, with approximately $IC_{50}$ of $70\;{\mu}g/mL$. These results suggest that delphinidin might be useful for cancer prevention.

  • The purpose of this research was to investigate the immuno-modulatory effect and anti-carcinogenic property of Cordyceps militaris(CM) and/or Paecilomyces japonicus (PJ). The proliferation of cultured splenocytes and thymocytes were enhanced by the addition of 10 ㎍/ml of CM and/or PJ. B lymphocytes subpopulation in splenocytes were increased both CM and/or PJ administered(p.o. for 7 days)-mice. Thymic T lymphocytes, especially TH cells were significantly increased in CM-administered mice. CM and/or PJ treatment inhibited the cell viability of L 1210 mouse leukemia and HL60 human leukemia cells and induced the apoptosis of L1210 and HL60 cells. In addition, CM and/or PJ increased the hemaggutination(HA) titer against SRBC. These results suggest that CM and/or PJ have an immuno-modulatory action and anti-carcinogenic property.

  • The purpose of this research was to investigate the effects of Chungjokupye-tang(CJKPT) on the anti-carcinogenic action. The cell viability of mouse spienocytes and thymocytes were enhanced by the addition of CJKPT. CJKPT were increased of splenic and thymic T lymphocytes, such as T/sub H/ cells were markedly increased by the treatment of CJKPT in vivo. CJKPT treatment induced the apoptotic cell death of Jurkat and HL60 leukemia cells. CJKPT reduced mitochondrial transmembrane potential and increased the expression of ICE, c-myc and p53 gene in Molt-4cells dose dependant manner. These results suggest that CJKPT have an anti-carcinogenic action via immunoregulatory mechanism.

  • Isothiocyanates are naturally occurring small molecules that are formed from glucosinolate precursors of cruciferous vegetables. Many isothiocyanates, both natural and synthetic, display anti-carcinogenic activity because they reduce activation of carcinogens and increase their detoxification. This minireview summarizes the current knowledge on isothiocyanates and focuses on their role as potential anti-cancer agents.

  • In this study, potato kimchi was prepared by applying heat to raw potatoes, and then the physico-chemical properties and anti-cancer effects of the kimchi were analyzed. The texture results indicated the potato kimchi had very good hardness and springiness attributes. During th late storage period, total vitamin C content of the kimchi slowly increased. In addition, the potato kimchi had non-volatile organic acid changes that promoted early aging; however, after the complete aging period, it was comparatively similar to other types of kimchi. Using the methanol extracts of various kimchi samples, the potato kimchi(solid 100%) showed the highest anti-carcinogenic effects in terms of anti-tumor activity in tumor bearing Balb/c mice with sarcoma-180 cells. In addition, the effects of the methanol extracts on hepatic glutathione S-transferase content were $289.76\;{\mu}mol/mg$ protein/min, $250.97\;{\mu}mol/mg$ protein/min, $251.20\;{\mu}mol/mg$ protein/min, $219.53\;{\mu}mol/mg$ protein/min, $183.79\;{\mu}mol/mg$ protein/min, for control kimchi, mul kimchi, and two potato kimchis [(solid 100%) and(solid 60%+kimchi juice 40%)], respectively. The in vivo anti-cancer effects of the potato kimchi were investigated using AGS human gastric adenocarcionoma cells and HT-29 human colon adenocarcionoma cells. Overall, an MTT assay revealed that the methanol extract of the potato kimchi showed the highest anti-carcinogenic effects.

  • BACKGROUND/OBJECTIVE: Licorice has been shown to possess cancer chemopreventive effects. However, glycyrrhizin, a major component in licorice, was found to interfere with steroid metabolism and cause edema and hypertension. The roasting process of licorice modifies the chemical composition and converts glycyrrhizin to glycyrrhetinic acid. The purpose of this study was to examine the anti-carcinogenic effects of the ethanol extract of roasted licorice (EERL) and to identify the active compound in EERL. MATERIALS/METHODS: Ethanol and aqueous extracts of roasted and un-roasted licorice were prepared. The active fraction was separated from the methylene chloride (MC)-soluble fraction of EERL and the structure of the purified compound was determined by nuclear magnetic resonance spectroscopy. The anti-carcinogenic effects of licorice extracts and licochalcone A was evaluated using a MTT assay, Western blot, flow cytometry, and two-stage skin carcinogenesis model. RESULTS: EERL was determined to be more potent and efficacious than the ethanol extract of un-roasted licorice in inhibiting the growth of DU145 and MLL prostate cancer cells, as well as HT-29 colon cancer cells. The aqueous extracts of un-roasted and roasted licorice showed minimal effects on cell growth. EERL potently inhibited growth of MCF-7 and MDA-MB-231 breast, B16-F10 melanoma, and A375 and A2058 skin cancer cells, whereas EERL slightly stimulated the growth of normal IEC-6 intestinal epithelial cells and CCD118SK fibroblasts. The MC-soluble fraction was more efficacious than EERL in inhibiting DU145 cell growth. Licochalcone A was isolated from the MC fraction and identified as the active compound of EERL. Both EERL and licochalcone A induced apoptosis of DU145 cells. EERL potently inhibited chemically-induced skin papilloma formation in mice. CONCLUSIONS: Non-polar compounds in EERL exert potent anti-carcinogenic effects, and that roasted rather than un-roasted licorice should be favored as a cancer preventive agent, whether being used as an additive to food or medicine preparations.

  • Rutin is one of the major flavonoids found in buckwheat (Fagopyrum esculentum Moench). While rutin is already known to exhibit anti-oxidative, anti-inflammatory, and anti-carcinogenic activities. However, the health beneficial function of rutin metabolites is not well understood. In DPPH radical scavenging assays, the present study found that 3,4-dihydroxyphenyl acetic acid had the highest total anti-oxidant activity, followed by 3,4-dihydroxyphenylacetic acid, rutin, homovanillic acid, and 3-hydroxyphenyl acetic acid. Further, 3,4-dihydroxyphenylacetic acid strongly reduced LPS-induced IL-6 production in RAW 264.7 cells, compared with other metabolites. Therefore, these results suggest that rutin metabolites have potential to be utilized as food ingredients with anti-oxidant and anti-inflammatory activities.

  • Conjugated linoleic acids (CLA) were identified in 1980's, since then it has been intensively studied due to its various beneficial health effects such as anti-inflammatory, anti-atherogenic, anti-carcinogenic and anti-diabetic/obesity effects. Isomer specificity of a number of CLA isomers, especially predominant isomer 9Z,11E- and 10E,12Z-CLA, is now recognized. However, the less prevalent CLA isomers have not been well characterized. Recently, studies have reported the distinctively different effects of 9E, 11E-CLA in colon cancer cells, endothelial cells, and macrophage cells compared to the rest of CLA isomers. In this review, various effects of CLAs, especially anti-inflammatory and anti-atherogenic effects, will be discussed with focusing on the isomer-specific effects and potential mechanism of action of CLA. At last, recent studies about 9E,11E-CLA in in vitro and animal models will be discussed.

  • Hwang Chil (Dendropanax morbifera Lev.) belongs to Aralia elata group. This plant is only found in Korea and is considered to be along with ginseng. The physiological activities of it have been reported as having scavenging effect on oxygen free radicals and anti-carcinogenic effect. As most of the anti-oxidants were effective on protecting hepatotoxicity from alcohol, hard tissues restoring and skin whitening, the effectiveness of Hwang Chil extracts was screened. (omitted)
