Abstract
Protein expression and secretion in insect cells have been widely studied in the baculovirus-infected insect cell system. In directly transfected insect cells only intracellular expression and purification of recombinant proteins have been studied in detail. To examine multiple recombinant protein variants, easy and fast expression and a purification screening system are required. The aim of this study was to establish an effective and rapid secretion system for human azurocidin using directly transfected insect cells. We also constructed and tested expression vectors possessing heterologous signal peptides derived from human azurocidin, yellow lupin diphosphonucleotide phosphatase/phosphodiesterase (PPD1), and papaya papain IV to secrete yellow lupin and red kidney bean purple acid phosphatases, PPD1, and papain IV. Our results demonstrate that the secretion vectors used here can direct recombinant proteins to the culture medium very effectively, allowing their simple purification on a small/medium scale. Based on secretion and activity analyses it seems that the azurocidin signal peptide is one of the most potent secretion signals.

Abstract
Insect cell-based expression systems are prominent amongst current expression platforms for their ability to express virtually all types of heterologous recombinant proteins. Stably transformed insect cell lines represent an attractive alternative to the baculovirus expression system, particularly for the production of secreted and membrane-anchored proteins. For this reason, transformed insect cell systems are receiving increased attention from the research community and the biotechnology industry. In this article, we review recent developments in the field of insect cell-based expression from two main perspectives, the production of secreted and membrane-anchored proteins and the establishment of novel methodological tools for the identification of bioactive compounds that can be used as research reagents and leads for new pharmaceuticals and insecticides.

Abstract
The BEVS (baculovirus expression vector system) is widely used for the production of proteins. However, engineered proteins frequently experience the problem of degradation, possibly due to the lytic nature of the conventional BEVS (herein referred to as L-BEVS). In the present study, a non-lytic BEVS (N-BEVS) was established by random mutagenesis of viral genomes. At 5 days post-infection, N-BEVS showed only 7% cell lysis, whereas L-BEVS showed 60% lysis of cells. The quality of protein expressed in both N- and L-BEVSs was examined further using a novel FRET (fluorescence resonance energy transfer)-based assay. To achieve this, we constructed a concatenated fusion protein comprising LUC (luciferase) sandwiched between EYFP (enhanced yellow fluorescent protein) and ECFP (enhanced cyan fluorescent protein). The distance separating the two fluorescent proteins in the fusion protein EYFP-LUC-ECFP (designated hereafter as the YLC construct) governs energy transfer between EYFP and ECFP. FRET efficiency thus reflects the compactness of LUC, indicating its folding status. We found more efficient FRET in N-BEVS compared with that obtained in L-BEVS, suggesting that more tightly folded LUC was produced in N-BEVS. YLC expression was also analysed by Western blotting, revealing significantly less protein degradation in N-BEVS than in L-BEVS, in which extensive degradation was observed. This FRET-based in vivo folding technology showed that YLC produced in N-BEVS is more compact, correlating with improved resistance to degradation. N-BEVS is thus a convenient alternative for L-BEVS for the production of proteins vulnerable to degradation using baculoviruses.

Abstract
Active beta1,3-N-acetylglucosaminyltransferase 2 (beta3GnT2) was produced in the baculovirus expression system (BES) and in stably transformed insect Tn-5B1-4 cells. beta3GnT2 was expressed as a secreted fusion protein with GFP(UV) with three different types of signal sequence to enhance the secretion of the fusion protein. In the stably transformed cells, the maximal beta3GnT2 activity differed between isolates, but their secretion efficiencies were similar. The difference between the maximal beta3GnT activities of the isolates studied was considered to be due to the presence of a copy number of the fusion gene, as determined on the basis of the results of Southern blot analysis. The beta3GnT activities of the culture supernatant in BES (Tn-5B1-4 cells) without or with the addition of the protease inhibitor, leupeptin, were 0.68 and 2.01 mU/ml, respectively. The stably transformed Tn-5B1-4 cells (Tn-pXme11) exhibited a beta3GnT activity of 6.83 mU/ml, which was 3.4-fold higher than that observed for BES with the leupeptin addition. The purity of fusion protein purified from the culture supernatant of the Tn-pXme11 was higher than 95% on SDS-PAGE, in contrast with that purified from the culture supernatant of the baculovirus-infected cells which contained low-molecular-weight fragments of the fusion protein. The stably transformed cell line is more suitable than BES for the efficient production of the secretory protein, beta3GnT2.

Abstract
Human alpha3/4 fucosyltransferase III (FT3; EC 2.4.1.65) synthesizes fucosylated glycoconjugates, namely the Lewis (Le) determinants. FT3 is detected in milk, gastric mucosa, kidney and other organs, but is found in very low amounts in these native tissues. In this work, we describe the expression of a soluble secretory form of FT3 (SFT3) in Spodoptera frugiperda (Sf9) insect cells using a non-lytic vector system. The coding sequence was cloned into the expression vector pIB/V5-His-TOPO which contains the transcriptional control of the Orgyia pseudotsugata multicapsid nucleopolyhedrosis virus immediate-early 2 (OpIE2) promoter. Transfected cells were selected using blasticidin-HCl. It was observed that the secreted activity SFT3 increased until the sixth day of culture when it reached the value 1.9 mU x 10(-6) cells and 13.4 mg/l, whereas only 5% of activity was retained inside the cells. Western blot analysis of secreted and intracellularly retained SFT3 had a similar variation. Comparison of the stable with the lytic baculovirus expression system showed that the former yielded approx. 13-fold more active SFT3, which was possibly due to a lower accumulation of intracellular SFT3.

Abstract
The cDNA that encodes the human mu opioid receptor (hMOR) has been cloned and expressed in Spodoptera frugiperda (Sf9) cells using a nonlytic vector system. The coding sequence fused to the cleavable glycoprotein signal peptide gp 64, and a C-terminal histidine tag was placed under the transcriptional control of the Orgyia pseudotsugata multicapsid nucleopolyhedrosis virus immediate-early 2 (OpIE2) promoter. Transfected cells were selected using Zeocin resistance and the receptor was constitutively expressed at approximately 12000 receptors per cell. Immunofluorescence images illustrated that more than 75% of the Sf9 cells expressed hMOR at the plasma membrane. This is the first report of the constitutive and heterologous expression of a G protein-coupled receptor in a stably transfected Sf9 cell line, under the control of the OpIE2 promoter.
