Objective: In the current work, we investigated the cytotoxic and apoptotic effects of Thymoquinone (TQ), an active compound of Nigella sativa (N. sativa) and Cis-platinum, on normal renal epithelial (GP-293) and human renal adenocarcinoma cell lines (ACHN). Methods: GP-293 and ACHN cell lines were cultured in Dulbecco's modified Eagle's medium (DMEM) with 10% Fetal bovine serum (FBS) and 1% penicillin plus streptomycin antibiotic. The MTT assay was used for cellular viability assessment. Viability of cells was observed using inverted light microscope 24, 48 and 72 h after exposure of the cells to various concentrations of TQ (1, 2.5, 5, 10, 50 and $100{\mu}g/ml$) and Cis-platinum (0.5, 1, 1.5, 2, 3, 6 and $12.5{\mu}g/ml$). Moreover, apoptosis was analyzed with a flow-cytometry method. The untreated cells were considered as control group. Results: Morphological changes such as reduced cell number and increased intercellular distance and reduced cell viability in ACHN and GP-293cell lines were observed in both TQ and Cis- platinum groups; however, Cis-platinum had greater effect on ACHN cell line than GP-293 cell line. In addition, GP-293 cell line was more sensitive to TQ compared to ACHN cell line. Furthermore, TQ and Cis-platinum had apoptotic effects on both ACHN and GP-293 cell lines. Conclusion: Our findings demonstrated that TQ and Cis-platinum had cytotoxic and apoptotic effects on both cell lines, However, GP-293 cell line was more sensitive to TQ. Additionally, Cis-platinum was more effective on ACHN cell line than on GP-293 cell line.

This study aimed to analyze the expression, clinical significance of filamin A (FLNA) in renal cell carcinoma (RCC) and biological effects in a cell line by regulating FLNA expression. Immunohistochemistry and Western blotting were used to analyze FLNA protein expression in 70 cases of RCC and normal tissues to study the relationship with clinical factors. FLNA lentiviral and empty vectors were transfected into RCC to study the influence of up-regulated expression of FLNA. FLNA siRNA was transiently transfected into ACHN kidney carcinoma cells by a liposome-mediated method and protein was detected by Western blotting. The level of expression was found to be significantly lower in RCC than normal tissues (p<0.05). No correlation was noted with gender, age, tumor size or pathological types (p>0.05), but links with lymph node metastasis, clinic stage and histological grade were noted (p<0.05). Loss of FLNA expression correlated significantly with poor overall survival time by Kaplan-Meier analysis (p<0.05). Results for biological function showed that ACHN cells transfected with FLNA had a lower survival fraction, significant decrease in migration and invasion, higher cell apoptosis, higher percentage of the G0/G1 phases, and lower MMP-9 protein expression compared with ACHN cells untransfected with FLNA (p<0.05). However, renal 786-0 cells transfected with FLNA siRNA had a higher survival fraction, significant increase in migration and invasion, and higher MMP-9 protein expression compared (p<0.05). In conclusion, FLNA expression was decreased in RCC and correlated significantly with lymph node metastasis, clinic stage, histological grade and poor overall survival, suggesting that FLNA may play important roles as a a tumor suppressor in RCC by promoting degradation of MMP-9.

Marine sponges have been a remarkably rich source of pharmacologically active and structurally diverse natural products. As a part of our continuing search for novel secondary metabolites of biomedical importance from marine invertebrate, we encountered the sponge Lipastrotethya sp. from Chuuk, Micronesia. The crude organic extract of this animal exhibited considerable cytotoxicity against the K562 cell line. Guided by the $^1H$ NMR analysis, flash chromatography of the crude extract followed by HPLC yielded a new triterpene glycoside, along with ten known saponins of the sarasinoside class. The structure of this new compound was determined by combined spectroscopic methods such as COSY, HSQC and HMBC experiment. Among these metabolites, six compounds exhibited moderate cytotoxicity against ACHN, MDA-MB-231, NCI-H23 and NUGC-3 cell lines.

An antitumor antibiotic named YS-1649 was isolated from the culture filtrate of a newly isolated fungus identified as Penicillium sp.. The fermentation yield reached about 40 mg per liter of the broth. YS-1649, a $\gamma$-Iactone - structured antibiotic, has the molecular fomular of $C_7H_6O_4$, Its structure was determined to be patulin by spectral analysis. It is active against some bacteria and showed cytotoxic effect on the proliferation of human breast cancer cell line, MCF-7, at concentrations of more than 0.048 $mu g/ml$. This compound also showed strong cytotoxic effect on the proliferation of human cancer cell lines, A549 and ACHN.

Objectives : This study was performed to efficiently make Black Panax Ginseng (BPG) and evaluate its antitumor activity. Methods : Panax ginseng was steamed at $95^{\circ}C$ for 3 h, dried and steamed again at $115^{\circ}C$ for 6 h. The main ginsenosides of BPG were $Rg_{3}$, $Rk_{1}$ and $Rg_{5}$. Results : Among the saponins in BPG, the amount of ginsenoside $Rg_{3}$ was determined by HPLC method. The 11.48 mg of ginsenoside $Rg_{3}$ was obtained from lg of dried BPG. The crude saponin fraction (CSF) of BPG was tested in vitro for its cytotoxic activities against various human cancer cell lines, such as ACHN, NCI-H23, HCT-15 and PC-3. The CSF of BPG exhibited stronger cytotoxic activity than that of red Panax ginsneng. CSF of BPG exhibited good cytotoxic activities against ACFIN, HCT-15, and PC-3 cell lines with $IC_{50}$ values of 60.3-90.8 ${\mu}g$/ml. However, CSF of BPG did not show any cytotoxic activity against NCI-H23 cell line. Conclusions : BPG produced by new manufacturing is more effective than BPG produced by existing processing in anticancer activity. And new BPG has a possibility of investigation because of high contents of Rg3, Rk1 and Rg5 that have various phisological activities.
