A stably transformed insect cell expression system is superior to a baculovirus expression system, since the expression system is sustained and there is no cell lysis, but the isolation of cell lines producing recombinant proteins is time-consuming and laborious. In this study, we developed a technique for the rapid isolation and efficient cultivation of sorted cells in a 24 well deep plate Bio...

Baculoviruses are insect viruses extensively exploited as eukaryotic protein expression vectors. Molecular biology studies have provided exciting discoveries on virus-host interactions, but the application of omic high-throughput techniques on the baculovirus-insect cell system has been hampered by the lack of host genome sequencing. While a broader, systems-level analysis of biological respons...

Recent successes in the pharmacotherapeutic treatment of breast cancer are associated with the use of selective estrogen receptor modulators. Two commonly prescribed pharmaceuticals in this class, tamoxifen and raloxifene, have been shown to have effects through estrogen receptor (ER)-independent mechanisms. Hyperactivation of phospholipase D (PLD) in certain tumor-derived cell lines have been ...

background: the poor permeability of the plasma and nuclear membranes to dna plasmids are two major barriers for the development of these therapeutic molecules. therefore, success in gene therapy approaches depends on the development of efficient and safe non-viral delivery systems. objectives: the aim of this study was to investigate the in vitro delivery of plasmid dna encoding hpv16 e7 gene ...

cholera toxin b subunit (ctb) has been extensively studied as an immunogen, adjuvant, and inducer of oral tolerance in many investigations. production of ctb has been carried out in the bacterial, plant, insect and yeast expression systems. in this study the expression of the ctb containing a 6xhis-tagged was performed by escherichia coli (e.coli) m15. the yield of purified pentameric recombina...

Recombinant protein expression often presents a bottleneck for the production of proteins for use in many areas of animal-cell biotechnology. Difficult-to-express proteins require the generation of numerous expression constructs, where popular prokaryotic screening systems often fail to identify expression of multi domain or full-length protein constructs. Post-translational modified mammalian ...

The cytochrome P450 superfamily encompasses a diverse group of enzymes that catalyze the oxidation of various substrates. The mouse CYP2J subfamily includes members that have wide tissue distribution and are active in the metabolism of arachidonic acid (AA), linoleic acid (LA), and other lipids and xenobiotics. The mouse Cyp2j locus contains seven genes and three pseudogenes located in a contig...
