Taxol is a chemotherapeutic drug which acts by stabilizing microtubules, preventing normal mitosis and resulting in a block of the cell cycle at G2 and M. The drug is isolated from the yew, Taxus sp. l.., and is currently being evaluated in a series of Phase II and Phase III clinical trials. Taxol blocks cells in the most radiosensitive phases of the cell cycle and thus could act as a cell cycl...

Background and objectives: Modeling cancer in vivo is a very important tool to investigate cancer pathogenesis and molecular mechanisms involved in cancer progression. Laboratory mice are the most common animal used for rebuilding human cancer in vivo. Cancer stem cells (CSCs) are the main reason of failure in cancer therapy because of tumor relapse and metastasis. Isolation of cancer stem cell...

Previous reports indicate that the NIX/BNIP3L gene acts as a pro-apoptotic factor by interacting with BCL2 and BCL-XL, playing an important role in hypoxia-dependent cell death and acting as a tumor suppressor. However, many studies also showed that NIX is linked to a protective role and cell survival in cancer cells. Nuclear factor-κB (NF-κB) can attenuate apoptosis in human cancers in respons...

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...

Background: It seems that Vinca. herbacea has an anti-tumor effect. Here, the immunotherapeutic effect of this compound is assessed against human ovarian cancer (SKOV3) cells because of the high incidence of this tumor in women. Materials and Methods: The cytotoxic activity of V. herbacea extract against human ovarian cancer (SKOV3) cells was determined by MTT assay. The apoptosis-inducing pote...
