Chaharmahal and Bakhtiari province is a most important endemism states of flora of Iran with a considerable plant species diversity in the country. In the present study the cytotoxic activity of 13 plant species grown in Chaharmahal and Bakhtiari have been evaluated on prostate (PC-3), breast (MCF-7), liver (HepG2), ovary (CHO) and melanoma (B16-F10) cancer cell lines. The cytotoxicity and apop...
Eukaryotic expression vectors have been used successfully in viral LT-expressing cell lines (ie. COS) to clone cDNAs encoding proteins that can be detected through their bio-activity or reactivity with specific antibodies. Since Chinese hamster ovary cells (CHO) have been used extensively for the isolation and characterization of somatic cell mutants, we felt it would be an advantage to develop...
Background and purpose: Today cancer is considered as one of the leading causes of death worldwide. An impressive number of modern drugs used in cancer treatment are isolated or derived from natural sources based on their use in traditional medicine. Cornus mas L. (Cornaceae) has medicinal applications in treating a wide range of diseases such as cancer. This study was designed to evaluate the ...
Mammalian cell lines are widely used to produce recombinant proteins. Stable transgenic cell lines usually contain many insertions of the expression vector in one genomic region. Transcription through transgene can be one of the reasons for target gene repression after prolonged cultivation of cell lines. In the present work, we used the known transcription terminators from the SV40 virus, as w...
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 ...
Studying the biophysical characteristics of glycosylated proteins and solving their three-dimensional structures requires homogeneous recombinant protein of high quality.We introduce here a new approach to produce glycoproteins in homogenous form with the well-established, glycosylation mutant CHO Lec3.2.8.1 cells. Using preparative cell sorting, stable, high-expressing GFP 'master' cell lines ...
ML236B is a potent competitive inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCoA reductase) (EC 1.1.1.34), the major regulatory enzyme in cholesterol biosynthesis. This compound inhibits cell growth when present in the culture medium of CHO-K1 cells at a concentration as low as 0.1 pg/ml. Addition of the product of the HMG-CoA reductase reaction, mevalonate, to the culture me...
Upon infection of Japanese encephalitis virus (JEV), baby hamster kidney (BHK-21) and Chinese hamster ovary (CHO) cells were killed by a mechanism involved in apoptosis. While readily established in a variety of cell lines, JEV persistence has never been successfully instituted in BHK-21 and CHO cells. Since stable expression of human bcl-2 in BHK-21 cells has been shown to delay JEV-induced ap...
