چکیده مقاله:

Molecular farming has been considered as a secure and economical approach for production of biopharmaceuticals. Human TNF Related Apoptosis Inducing Ligand (TRAIL) as a promising biopharmaceutical candidate has been produced in different expression hosts. However, little attention has been paid to molecular farming of the TRAIL in spite of numerous advantages of plant expression systems. Therefore, in this study the cytoplasmic production of the TRAIL was tackled in Nicotiana tabacum using Agrobacterium tumefaciens LBA 4404. Initially, the desired coding sequence was obtained using PCR technique on the constructed human cDNA library. Afterward, the necessary requirements for expression of the TRAIL in plant cell system were provided through sub-cloning into 35S-CaMV helper and final 0179-pGreen expression vectors. Then, the final TRAIL-pGreen expression vector was cloned into A. tumefaciens LBA 4404. Subsequently, the N. tabacum cells were transformed through co-culture method and expression of the TRAIL was confirmed by western blot analysis. Finally, the recombinant TRAIL was extracted through chromatographic technique and biological activity was evaluated through MTT assay. The result of western blot analysis indicated that only monomer and oxidized dimer forms of the TRAIL can be extracted from the N. tabacum cells. Moreover, the lack of trimeric assembly of the extracted TRAIL diminished its biological activity in sensitive A549 cell line. In conclusion, although N. tabacum cells can successfully produce the TRAIL, proper assembly and functionality of the TRAIL were unfavorable.
