background: nigella sativa has been a nutritional flavoring factor and natural treatment for many ailments for so many years in medical science. earlier studies have been reported that thymoquinone (tq), an active compound of its seed, contains anticancer properties. previous studies have shown that tq induces apoptosis in breast cancer cells but it is unclear the role of p53 in the apoptotic p...

background: p19 cells are mouse embryonic carcinoma cells which contain pluripotent ability, like stem cells, to differentiate into different cell lines. there are several properties for this cell line that make it a valuable cell model for study of developmental stages. methods: at the first step, pts2-egfp coding sequence which was cloned in pucd2.hygro vector was used for transfection in to ...

recent evidences suggest that multiple myeloma phenotypes (mmps) are involved in the infiltration of multiple myeloma-affected marrow foci. in this study, the effects of arsenic trioxide on the invasive and angiogenic phenotypes of multiple myeloma (mm) cell line were assessed on a dose-response and time-course basis. multiple myeloma cell line, karpas 707, was treated with step-wise elevated c...

   The aerial parts of Stachys laxa Boiss. and Buhse.from Siah-bishe in Mazandaran province, Stachys trinervis Aitch. and Hemsl. from Karaj in Alborz province, Stachys subaphylla Rech. F. and Stachys turcomanica Trautv. from Golestan province have been collected in May 2008. Total extracts were obtained through MeOH/H2O (80/20) and then partitioned between CHCl3, EtOAc and MeOH. These fractions...

Background and objectives: ZatariamultifloraBioss. (ZM) has shown several effects in gastrointestinal, respiratory and nervous system. In this study, the effect of Z. multiflora was examined in colon cancer cell lines of Caco-2. Methods: Total extract and petroleum ether, chloroform and methanol fractions of the plant were prepared us...

There are considerable efforts to identify naturally occurring substances as new drugs in cancer therapy. Many components of medicinal plants have been identified that possess substantial anticancerous properties. This prompted us to investigate the effect of Scrophularia striata (an Iranian species belonging to the Scrophulariace family) extract on the growth of astrocyte cancer cell line (132...
