Construction and characterization of a replication-competent retroviral shuttle vector plasmid.
We constructed two versions of an RCASBP-based retroviral shuttle vector, RSVP (RCASBP shuttle vector plasmid), containing either the zeocin or blasticidin resistance gene. In this vector, the drug resistance gene is expressed in avian cells from the long terminal repeat (LTR) promoter, whereas in bacteria the resistance gene is expressed from a bacterial promoter. The vector contains a bacteri...
متن کاملProperties and construction of plasmid pFW213, a shuttle vector with the oral Streptococcus origin of replication.
Streptococcus parasanguinis is among the most successful colonizers of the human body. Strain FW213 harbors a 7.0-kb cryptic plasmid, pFW213, with a copy number at 5 to 10 per chromosome. Sequence and functional analyses of pFW213 revealed that the open reading frame (ORF) encoding the replication protein (Rep) is essential for the replication of pFW213, and the putative plasmid addiction syste...
متن کاملConstruction and characterization of a highly efficient Francisella shuttle plasmid.
Francisella tularensis is a facultative intracellular pathogen that infects a wide variety of mammals and causes tularemia in humans. It is recognized as a potential agent of bioterrorism due to its low infectious dose and multiple routes of transmission. To date, genetic manipulation in Francisella spp. has been limited due to the inefficiency of DNA transformation, the relative lack of useful...
متن کاملCharacterization of the plasmid pMB1 from Bifidobacterium longum and its use for shuttle vector construction.
The nucleotide sequence of the 1847-bp Bifidobacterium longum B2577 cryptic plasmid pMB1 was determined. The plasmid had a G+C content of 62.0%, and contained two open reading frames, orf1 and orf2, likely arranged in an operon. The proteins encoded by orf1 and orf2 show the highest degree of similarity with similarly arranged peptide sequences translated from Corynebacterium glutamicum pXZ1014...
متن کاملDelivery of short hairpin RNA sequences by using a replication-competent avian retroviral vector.
While recent studies have demonstrated that retroviral vectors can be used to stably express short hairpin RNA (shRNA) to inhibit gene expression, these studies have utilized replication-defective retroviruses. We describe the creation of a replication-competent, Gateway-compatible retroviral vector capable of expressing shRNA that inhibits the expression of specific genes.
