The human multidrug resistance protein (MRP1) contributes to drug resistance in cancer cells. In addition to an MDR1-like core, MRP1 contains an N-terminal membrane-bound (TMD(0)) region and a cytoplasmic linker (L(0)), both characteristic of several members of the MRP family. In order to study the role of the TMD(0) and L(0) regions, we constructed various truncated and mutated MRP1, and chime...
BACKGROUND Various protein expression systems, such as Escherichia coli (E. coli), Saccharomyces cerevisiae (S. cerevisiae), Pichia pastoris (P. pastoris), insect cells and mammalian cell lines, have been developed for the synthesis of G protein-coupled receptors (GPCRs) for structural studies. Recently, the crystal structures of four recombinant human GPCRs, namely β2 adrenergic receptor, aden...
Mosquito iridescent viruses (MIV) are members of the genus Chloriridovirus that currently contains only the type IIV-3 from Aedestaeniorhynchus. The complete genome of invertebrate iridescent virus -3 (IIV-3) has been sequenced and the availability of a tissue culture system would facilitate functional genomic studies. This investigation, using quantitative PCR and electron microscopy, has dete...
Agonist-independent properties of the human f32-adrenergic receptor (fl2AR) were studied using the baculovirus expression system in Sf9 cells. In the absence of agonist but in the presence of GTP, membranes from cells expressing the fl2AR exhibited higher levels of cAMP production than did membranes from uninfected cells or from cells infected with wild-type baculovirus. The increase in cAMP pr...
Background and aims The nine-item Internet Gaming Disorder Scale - Short Form (IGDS-SF9) is brief and effective to evaluate Internet Gaming Disorder (IGD) severity. Although its scores show promising psychometric properties, less is known about whether different groups of gamers interpret the items similarly. This study aimed to verify the construct validity of the Persian IGDS-SF9 and examine ...
Nosema bombycis is a destructive, obligate intracellular parasite of the Bombyx mori. In this study, a single-chain variable fragment (scFv) dependent technology is developed for the purpose of inhibiting parasite proliferation in insect cells. The scFv-G4, which we prepared from a mouse G4 monoclonal antibody, can target the N. bombycis spore wall protein 12 (NbSWP12). Indirect immunofluoresce...
DNA encoding ricin B chain was derived from preproricin genomic DNA and ligated into the baculovirus transfer vector, pAcGP67A. Co-transfection of Spodoptera frugiperda Sf9 cells with BaculoGold DNA was followed by limiting dilution purification of recombinant baculovirus. Infection of SF9 cells at a multiplicity of infection of 1 in the presence of 25 mM lactose produced 3 mg/l of soluble, gly...
Three known Cinchona alkaloids of the quinine type, quinine (1), cupreine (2), cinchonine (3), and the possible artifact cinchonine-HCl (3-HCl), along with two new ones, acetylcupreine (4) and N-ethylquinine (5), have been isolated from the bark of Remijia peruviana (Rubiaceae). Their stereochemical structures were established by high resolution NMR spectroscopy. Alkaloids 2-4 had antifeedant e...
