چکیده

Expression of bacterial luciferase enzyme (lux) in eukaryotic cells would provide a new bioreporter system for in vivo imaging and diagnostics technology. In spite of this, until now only a few efforts have been made to express bacterial luciferase enzyme in eukaryotic cells. We attempted to synthesize an expression construct of luxA and luxB genes from Vibrio fischeri. The luxA and luxB genes were cloned into the MCS of pTZ57R via the 5' kpnI, BamHI and BamHI, EcoRI restriction sites to generate pTZ57R/luxA and pTZ57R/luxB respectively, then newly synthesized constructs were cleaved with the same enzymes and respectively cloned into the pcDNA3.1(+) (Hyg) and pcDNA3.1(+) (Neo) expression vectors to create pcDNA3.1(+) (Hyg)/luxA and pcDNA3.1(+) (neo)/luxB. Recombinant constructs were cotransfected to the NIH3T3 cell line. Gene expression was confirmed by reverse transcription-polymerase chain reaction, sodium dodecyl sulfate-polyacrylamide gel electrophoresis and Western blotting; in addition, bioluminescence characteristics of transfected NIH3T3 cell lines were evaluated by decanal supplement. In conclusion, in the current research, separate vector systems were constructed, which are composed of bacterial luciferase genes (luxA and luxB) that accordingly have not already been reported. These results hold promise toward the potential development of an autonomous light-generating lux reporter system in eukaryotic cells.

Identification of genes and gene products necessary for bacterial bioluminescence.

Expression of luminescence in Escherichia coli was recently achieved by cloning genes from the marine bacterium Vibrio fischeri. One DNA fragment on a hybrid plasmid encoded regulatory functions and enzymatic activities necessary for light production. We report the results of a genetic analysis to identify the luminescence genes (lux) that reside on this recombinant plasmid. lux gene mutations ...

Cloning and expression of the Photobacterium phosphoreum luminescence system demonstrates a unique lux gene organization.

The organization of the lux structural genes (A-E) in Photobacterium phosphoreum has been determined and a new gene designated as luxF discovered. The P. phosphoreum luminescence system was cloned into Escherichia coli using a pBR322 vector and identified by cross-hybridization with Vibrio fischeri lux DNA. The lux genes were located by specific expression of P. phosphoreum DNA fragments in the...

Vibrio fischeri lux genes play an important role in colonization and development of the host light organ.

The bioluminescent bacterium Vibrio fischeri and juveniles of the squid Euprymna scolopes specifically recognize and respond to one another during the formation of a persistent colonization within the host's nascent light-emitting organ. The resulting fully developed light organ contains brightly luminescing bacteria and has undergone a bacterium-induced program of tissue differentiation, one c...
