RNA interference (RNAi), a process of sequence-specific gene suppression, has been known as a natural gene regulatory mechanism in a wide range of organisms. Recently, a small-interference RNA (siRNA) technology has been reported to produce post-transcriptional gene silencing in mammalian cells. In the present study, we constructed a human U6 promoter-driven mammalian expression vector to produ...

background: herpes simplex virus type 2 (hsv-2) is highly prevalent and major cause of genital herpes in humans. the life-long nature of infection and the increasing prevalence of genital herpes imply that vaccination is the best strategy for controlling the spread of infection and limiting hsv disease. hsv glycoprotein d (gd) is one of the most important viral immunogen which has an essential ...

Production of recombinant proteins is essential for many applications in both basic research and also in medicine, where recombinant proteins are used as pharmaceuticals. This review summarizes procedures involved in recombinant protein expression and purification, including molecular cloning of target genes into expression vectors, selection of the appropriate expression system, and protein pu...

background : amelogenins are the major components of enamel matrix proteins. enamel matrix derivatives (emd) can be used in periodontal diseases to regenerate periodontal tissues. the main aim of this study was to evaluate ex-pression of full-length functional recombinant human amelogenin (rham) in iranian lizard leishmania (i.l.l.) as an alternative eukaryotic expression system. methods : huma...

The mammalian circadian timing system and metabolism are highly interconnected, disruption of this coupling is associated with negative health outcomes. Krüppel-like factors (KLFs) transcription that govern metabolic homeostasis in various organs. Many KLFs show a expression the liver. Here, we loss clock-controlled KLF10 hepatocytes results extensive reprogramming mouse liver transcriptome, wh...

We describe the cloning and characterization of a human homolog of the yeast transcription/RNA-processing factor Ssu72, following a yeast two-hybrid screen for pRb-binding factors in the prostate gland. Interaction between hSsu72 and pRb was observed in transfected mammalian cells and involved multiple domains in pRb; however, so far, mutual effects of these two factors could not be demonstrate...

objective(s) nonviral vector can be an attractive alternative to gene delivery in experimental study. in spite of some advantages in comparison with the viral vectors, there are still some limitations for efficiency of gene delivery in nonviral vectors. to determine the effective expression, the recombinant escherichia coli lacz genes were cloned into the different variants of pcdna3.1 and then...
