The use of medicinal plants in the treatment of diseases has a long history dating back to the presence of humans on earth. Cancer has almost been an incurable disease, and among the various cancers, breast cancer is the most common type of cancer among women and imposes an enormous burden on patients. Although medical and surgical solutions have been proposed for the disease, it has not been successful enough to treat the disease in many patients. In recent years, more studies have been done on the effects of medicinal plants on breast cancer, and scientists are trying to find the exact mechanisms of action for these plants to find effective ways for controlling cancer cell growth. This article focuses on P53 and MDM2, two very important genes involved in regulation of cell growth and proliferation both in cancer and normal tissue, and we also gathered the list of natural compounds targeting the MDM2-p53 pathway. Our results provide a list of plant families that can influence this pathway and have great potential in designing treatments against cancers that encompass deregulation of the MDM2-p53 pathway.

Environmental stresses affect plant growth and cause losses worth hundreds of million dollars of agricultural industry each year. Many genes induced in response to environmental stresses. The DREB1A gene is a stress-inducible transcription factor that its overexpression increased tolerance to environmental stress in transgenic plants. DNA was extracted from Arabidopsis thaliana var. Col.0 plants and DREB1A gene amplified by particular primers. After purification, PCR products were cloned into pGEMT-EASY vector and transferred into E. coli strain DH5α competent cells. Blue/white colonies were analyzed and present of the DREB1A gene revealed by restriction analysis and sequencing test. A 668-bp XbaI/BamHI digested fragment of DREB1A gene from pGEMT::DREB1A construct cloned in pBI121 plasmid. The recombinant plasmids were transferred into Agrobacterium tumefaciens cells strain of LBA4404 and transformed cells were cultured on selective medium that supplied with kanamycin and rifampycin. As a result of gel electrophoresis of Agrobacterium colonies-PCR product, band existing on expected size show that the DREB1A gene was cloned in to pBI121 binary vector. At time, Agrobacterium cells containing of pBI121::DREB1A construct are using for product of environmental stress tolerant plants.
