Cisplatin, as a chemotherapy drug, causes serious side effects in the advanced stages of the cancer. Recently, Artemisia has been considered for its bioactive compounds, anti-proliferative and anti-inflammatory effects. The aim of this study was to evaluate the anti-cancer and anti-metastatic effects of the methanolic extract of aerial organs of Artemisia and cisplatin, either alone or in combination, in human ovarian cancer cell line A2780. The viability of A2780 cells after treatment with Artemisia extract, cisplatin and their combination was evaluated by MTT assay and the alterations in the morphology of the cell nuclei were examined by DAPI staining. The induction of apoptosis was assessed by Annexin V test, cell migration and changes in expression levels of apoptotic genes (Bax and P53) and metastasis (MMP2 and MMP9) using real-time PCR. MTT test data showed that Artemisia extract, cisplatin and their combination decreased the viability of ovarian cancer cells. DAPI and Annexin V indicated the DNA fragmentation and increased percentage of cellular apoptosis in comparison with the control group. The migration and real-time PCR data showed a decline in thr cell invasion and expression of genes involved in metastasis (MMP2 and MMP9) in cancer cells while the expression of apoptotic genes (Bax and P53) was increased in the treated groups. The results of this study showed that while both Artemisia extract and cisplatin posses anti-proliferative effect, apoptotic and suitable anti-metastatic effects on their own in A2780 cell line, their combination have synergic effects and posses those desired properties in lower concentration of cisplatin, which can reduce the side effects of cisplatin in cancer treatment.

Pancreatic cancer is one of the most deadly and aggressive cancers; Fluorouracil induces apoptosis and cell cycle arrest in cancer cells. In the present study; the effect of Fluorouracil on different stages of the cell cycle and the expression of genes involved in the internal pathway of apoptosis in the AsPC-1 cell line (human pancreatic cancer) were investigated. In order to do so, MTT assay was used to evaluate the cytotoxic effect of Fluorouracil on AsPC-1 cell proliferation; The type of induced cell death and cell cycle changes were investigated by flow cytometry; changes in the expression level of genes (BAX, Bcl-2, APAF-1, Caspase-3, Caspase-9, p53, p21) were examined by Real-time PCR. Quantitative data were analyzed at the significant level of (p<0.05). The MTT assay results showed that Fluorouracil decreased AsPC-1 cell proliferation in a concentration-dependent manner. The results of flow cytometry analysis showed that increased percentage of apoptotic cells in the treated cells; Fluorouracil induces S phase cell cycle arrest in AsPC-1 cells and reduced distribution in the G1 phase. The Real-time PCR results in treated cells showed an increase in the expression of genes in the mitochondrial apoptotic pathway as well as genes effective in regulating the cell cycle. Fluorouracil reduces cell proliferation and induces apoptosis by increasing the expression of genes involved in the Intrinsic apoptotic pathway in AsPC-1 cells; Fluorouracil also caused cell cycle arrest in these cells by regulating the (p53, p21) genes.
