Over the past decade variety of hosts and vector systems for recombinant protein expression has increased dramatically. Researchers now select from among mammalian, insect, yeast, prokaryotic hosts, number vectors available use in these organisms continues to grow. With availability cDNAs coding sequencing information, it is certain that other, yet be developed will important future. Despite de...

Development of artificial cell models requires encapsulation of biomolecules within membrane-bound compartments. There have been limited studies of using mammalian cell-free expression (CFE) system as the 'cytosol' of artificial cells. We exploit glass capillary droplet microfluidics for the encapsulation of mammalian CFE within double emulsion templated vesicles. The complexity of the physicoc...

toll like receptors (tlrs) recognize pathogens and generate an immediate defense response by inducing the production of pro-inflammatory cytokines, which rapidly destroy or limit the pathogens. in their bridging role, tlr downstream signals link innate and adaptive immunity, particularly by mediating dc maturation and activation of pathogen specific t lymphocytes. these pathways lead to the act...

toxoplasmosis is a worldwide infection which is commonly asymptomatic but can cause serious medical problems in immunocompromised individuals and fetus. the infection also causes considerable economic loss because of abortion in livestock, mostly in sheep and goats. dna vaccination may be a powerful approach against intracellular parasites such as toxoplasma gondii. the goal of this study was t...

to construct of an eukaryotic expression vector encoding herpes simplex virus type 2 (hsv-2) glycoprotein d (gd2), an iranian isolate of hsv-2 was propagated in hela cell line and its dna was extracted and used as template in polymerase chain reactions (pcr), to amplify gd2 gene. primers were designed and the restriction enzyme sites for ecori and xhoi were considered at their 5′ ends respectiv...

The production of mammalian proteins in sufficient quantity and quality for structural and functional studies is a major challenge in biology. Intrinsic limitations of yeast and bacterial expression systems preclude their use for the synthesis of a significant number of mammalian proteins. This creates the necessity of well-identified expression systems based on mammalian cells. In this paper, ...

The mammalian testis is a complex organ that serves two important functions, synthesis of steroids, with significant amount of estrogenic hormones produced and production of spermatozoa. Estrogen receptors (ERs) are expressed in cells of the testis as well as the epididymal epithelium. We have demonstrated that estrogen receptor expression is higher in reproductive tissues as compared to non-re...

Precise interpretation of the transcriptome sequences in the several species showed that the major part of genome has been transcribed; however, just a few amounts of the transcription sequences have open-reading frames which are conversed during the evolution. So, it is unlikely that many of the transcribed sequences code the proteins. Among the all human non-coding transcripts, at least 10000...
