عنوان انگلیسی Expression of Recombinant Human Amelogenin in Iranian Lizard Leishmania and Its Biological Function Assay
چکیده انگلیسی مقاله 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 : Human cDNA encoding a 175-amino acid amelogenin expression cassette was sub cloned into a pLEXSY vector. The construct was transferred into Leishmania cells by electroporation. The protein production was surveyed in the transcription and the translation levels. The expressed protein was purified and some of its biological properties were investigated in comparison to EMD and negative control. Results : Expression of rhAm was confirmed by RT-PCR and western blot test in Leishmania cells. Purified rhAm sig-nificantly inhibited the formation of tartrate-resistant acid phosphatase positive (TRAP+) multinuclear cells in calcitriol stimulated mouse marrow cultures. Moreover, it significantly promoted proliferation and DNA synthesis in L929 mouse fibroblast cells. Conclusion : Functional rhAm was successfully expressed in I.L.L. Easy handling and post translation modification were the main advantages of this expression system. It is suggested to investigate molecular properties of this rhAm in the future.
