This study investigated the effects of mycelia of Lentinus edodes mushroom-cultured Glycyrrihiza radix(LMG) on cancer cell lines and sarcoma 180(S-180), as well as on human mast cells. In an anti-cancer tests using Hep3B(hepatic cancer cell), MCF-7(breast cancer), and HeLa(uterine cancer) cells, LMG extract exhibited greater anti-proliferation effects than Glycyrrihiza glabra(GG) extract. LMG extract multiplication restraining effects were 60% that of ethanol at 3 mg/mL extract also displayed tumor suppressive effects in mice injected with S-180 cells. The growth-inhibition rates against tumor cells were 56% for LMG and 37% for GG. When LMG was added to human mast cells, the Intensity of RT-PCR products using primers($FC{\varepsilon}RI\;c-kit$) decreased. significantly compared with that of control. These results suggest that Lentinus edodes Mushroom-Cultured Glycyrrhiza glabra has an anti-proliferation effects against cancer cell lines(Hep3B, MCF-7 and HeLa) and S-180 tumors and will be also beneficial in treating allergic reactions.

Objectives : We selected three herb-combined remedies, Bigihwan (BGH), Daechilgitang (DCGT) and Mokwhyangbinranghwan (MHBRH), through Donguibogam text-mining analysis, and evaluated their anti-cancer effects on human hepatocellular carcinoma Hep3B cells. Methods : Cytotoxicity was assessed by an MTT assay. Apoptosis rate, autophagy and ROS level were detected by flow cytometry. The autophagy was also observed by Cyto-ID staining fluorescence microscopy. The expression of autophagy, mitophagy and pexophagy regulatory proteins was detected by Western blot analysis. Results : BGH showed the strongest effect among the three prescriptions in inhibiting Hep3B cell viability, which was associated with the induction of apoptosis and autophagy. Autophagy blockers improved cell viability and reduced apoptosis after BGH and DCGT treatments, indicating that autophagy by these prescriptions enhanced Hep3B cells against their cytotoxicity. However, MHBRH enhanced the reduction of cell viability and apoptosis by autophagy blockers. Induction of autophagy by BGH treatment was associated with mitophagy due to mitochondrial dysfunction than DCGT and MHBRH-treated cells. In addition, induction of apoptosis by BGH treatment was ROS-dependent and showed the possibility of pexophagy involvement. Conclusion : Although further studies need to be conducted to study the efficacy and mechanism of accurate anticancer activity, the present results will serve as important sources of understanding the mechanism of action of herbal remedies prescribed for liver disease as documented in Donguibogam.

This study aims to provide basic data on useful functional ingredients in red ginseng by studying the anti-inflammatory and anti-cancer effects of convergence of ginsenoside Rh2(Rh2) and compound K(CK) isolated from amplified red ginseng. Therefore we examined cytotoxicity in Hep3B, activity of IL-6 induced STAT3 luciferase and survival concentration of cells in B16F10 and HaCa T. According to the experimental results, when the Rh2 and CK mixture were 10 ug/ml, there was no cytotoxicity in Hep3B cells and the anti-inflammatory effect of IL-6 reduction ratio was 102%. In addition, Rh2 and CK mixture were observed to be toxic in melanoma cell line B16F10 and HaCa T (human keratinocyte) at 50 uM. FACS(fluorescence activated cell sorting) analysis showed that annexin V was not expressed and melanoma cells and keratinocyte were desorbed and killed. It can be assumed that the mechanism of killing through this phenomenon is due to the cell death of anoikis-type, and it is necessary to study the changes of cell adhesion proteins in the future in order to clarify the cell death signal system.

Lonicerae flos aqua-acupuncture solution (LFAS) and Lonicerae flos water-extracted solution (LFWS) were prepared and tested for chemopreventive potentials. Three biomarkers [quinone reductase (QR), ornithine decarboxylase (ODC), glutathione(GSH)] were used to test chemopreventive potential of LFAS. LFAS was potent inducer of QR activity in Hepa1c1c7 murine hepatoma cells, whereas LFWS is less potent. LFAS and LFWS were also induced QR activities in cultured human hepatoma Hep3B cells. The effect of LFAS and LFWS were tested on the growth of Acanthamoeba castellanii. Proliferation of Acanthamoeba castellanii was inhibited by LFAS and LFWS at concentrations of $0.1{\times},\;0.5{\times}\;1{\times},\;and\;3{\times}.$ In addition, GSH levels were increased about 2-fold with LFAS and 1.5-fold with LFWS in cultured murine hepa1c1c7 cells. LFAS and LFWS were also shown to increase GSH levels in human Hep3B cells. These results suggest that LFAS has chemopreventive potential by inducing QR activity, inhibition of ODC activity and increasing GSH levels.

Objectives : In this study, it was investigated the anti-inflammatory, anticancer, and antioxidant effects of Jayangdaebo-tang (JDT) consisting of twelve herbs before and after fermentation. Methods : JDT extract was fermented using the Lactoplantibacillus plantanum (JDT-L), Bacillus subtilis (JDT-B), and L. plantanum plus B. subtilis (JDT-L+B). The effects of each extract were measured in LPS-stimulated RAW264.7 cells, MCF-7 breast cancer and A549 lung cancer cells, and H₂O₂-stimulated HepG2 cells. Results : The extracts of JDT-L, JDT-B and JDT-L+B at 1 ㎎/㎖ decreased significantly the levels of nitric oxide (NO) in LPS-treated RAW264.7 cells and also inhibited the expression of iNOS and COX-2, and the phosphorylation of ERK and NF-κB. The JDT-L+B extract decreased significantly the expression of apoptotic proteins, Bax, cleaved caspase-3, and PARP in MCF-7 and A549 cancer cells. The JDT-L, JDT-B and JDT-L+B extracts increased significantly the cell viability in H₂O₂-stimulated HepG2 cells and the JDT-L+B extract decreased significantly the expression of SOD, catalase, HO-1, and NRF-2. Among fermented JDT extracts, JDT-L+B was the best effective on response of macrophage inflammation, cancer cell apoptosis, and liver cell damage. Conclusions : Our results were suggested that the fermentation can be used as a useful way to enhance the biological activity of JDT.

In the present investigation, a series of some novel 1,3-diaryl/heteroarylprop-2-en-1-one derivatives (3a-j) have been synthesized and evaluated for their in vitro cytotoxicity against three cancer cell lines, two hepatocarcinoma cell lines HUH-7, Hep-3b and one leukemia cancer cell line MOLT-4. Based on these results, structure-activity relationship (SAR) was studied on modification of $R^1$ and $R^2$ to identify the compound with maximum potency. Amongst the compounds, 3b and 3d strongly inhibited the growth of Hep-3b and MOLT-4 cells with $IC_{50}$ value of 3.39 and $3.63{\mu}M$ respectively. The results obtained from the inhibitory study had further been supported by the reactive oxygen species (ROS) measurement using flow cytometry in MOLT-4 cells. These observations collectively reveal that compounds comprising 1,3-diarylprop-2-en-1-one framework with pyrazole ring at position-3 and heteroaryl/aryl substituents at position-1 can be used as promising anticancer agents.

Antiproliferative activity of the ethanol extract of Atractylodes japonica rhizomes (AJEX) was investigated using methyl thiazolyl tetrazolium (MTT) assays with various cancer cell lines (HL-60, MCF-7, SK-Br-3, MDA-MB-453, HepG2, Hep3B, PC-3, LNCaP, MKN 28, MKN 45, and HT-29 cells). Gastric carcinoma cell lines were the most responsive in terms of cell proliferation. The $IC_{50}$ of MKN 28 and MKN 45 cells were 35.98 and 27.57 ${\mu}g/mL$, respectively. Moreover, gastric carcinoma cells exposed to AJEX underwent apoptosis, as determined by Annexin V binding assay. Compared to respective control level, exposure to the AJEX at each $IC_{50}$ concentration resulted in a remarkable increase in the shift of cell populations. Present results suggest that AJEX possess potential anticancer properties.

Hepatocellular carcinoma (HCC) is a primary liver cancer with high global incidence and mortality rates. Current candidate drugs to treat HCC remain lacking and those in use possess undesirable side effects. In this investigation, the antiproliferative effects of dentatin (DTN), a natural coumarin, were evaluated on HepG2 cells and DTN's probable preliminary molecular mechanisms in apoptosis induction were further investigated. DTN significantly (p<0.05) suppressed proliferation of HepG2 cells with an $IC_{50}$ value of $12.0{\mu}g/mL$, without affecting human normal liver cells, WRL-68 ($IC_{50}$ > $50{\mu}g/mL$) causing $G_0/G_1$ cell cycle arrest via apoptosis induction. Caspase colorimetric assays showed markedly increased levels of caspase-3 and caspase-9 activities throughout the treatment period. Western blotting of treated HepG2 cells revealed inhibition of $NF-{\kappa}B$ that triggers the mitochondrial-mediated apoptotic signaling pathway by up-regulating cytoplasmic cytochrome c and Bax, and down-regulating Bcl-2 and Bcl-xL. The current findings suggest DTN has the potential to be developed further as an anticancer compound targeting human HCC.

Background: Ginsenoside F2 (GF2), a minor component of Panax ginseng, has been reported to possess a wide variety of pharmacological activities. However, its effects on glucose metabolism have not yet been reported. Here, we investigated the underlying signaling pathways involved in its effects on hepatic glucose. Methods: HepG2 cells were used to establish insulin-resistant (IR) model and treated with GF2. Cell viability and glucose uptake-related genes were also examined by real-time PCR and immunoblots. Results: Cell viability assays showed that GF2 up to 50 μM did not affect normal and IR-HepG2 cell viability. GF2 reduced oxidative stress by inhibiting phosphorylation of the mitogen-activated protein kinases (MAPK) signaling components such as c-Jun N-terminal kinase (JNK), extracellular signal-regulated kinase 1/2 (ERK1/2), and p38 MAPK, and reducing the nuclear translocation of NF-κB. Furthermore, GF2 activated PI3K/AKT signaling, upregulated the levels of glucose transporter 2 (GLUT-2) and GLUT-4 in IR-HepG2 cells, and promoted glucose absorption. At the same time, GF2 reduced phosphoenolpyruvate carboxykinase and glucose-6-phosphatase expression as well as inhibiting gluconeogenesis. Conclusion: Overall, GF2 improved glucose metabolism disorders by reducing cellular oxidative stress in IR-HepG2 cells via MAPK signaling, participating in the PI3K/AKT/GSK-3β signaling pathway, promoting glycogen synthesis, and inhibiting gluconeogenesis.
