Transient expression of recombinant human cytokine genes in transgenic Chinese materia medica cell

Article Review   by:TsingHua     Original Author: Chinese Traditional and Herbal Drugs
ª
 
Object To explore the feasibility of breeding genetic modified (GM) medicine by expressing human cytokine in transgenic Chinese materia medica Methods Human interferon α gene and RANTES gene available from the amplification in vitro were enzymatically excised, recoveried, and inserted into intermediate vectors The recombinants were identified by double enzyme digestion of EcoRⅠand HindⅢ The plasmids were extracted from Escherichia coli and introduced into A tumefaciens, and the transformants harboring binary vectors were screened by addition of antibiotics of kanamycin (Km) and rifampicin (Rif), and the explants of M charantia and P vulgaris were transformed by co cultivation of leaf disks with A tumefaciens strain Results RT PCR was applied to detect the transient expression of human interferon α gene and RANTES gene in transformed medicinal herbal calli Conclusion The expression of recombinant human interferon α gene and RANTES gene in transgenic M charantia and P vulgaris cells was firstly reported, which opens an alternative road to antivirus, especially anti AIDS virus, by using transgenic Chinese materia medica
