Objective: To study the role of transforming growth fa ctor ?1(TGF-?1) in the procession of human oral squamous cell carcinoma. Methods: Immunohistiochemical techinic was used to determine o ncogene c-myc,c-erbB2,TGF-?1 and EGFR protein expression in oral squamou s cell carcinoma cell line TSCCa and metastasis carcinoma cell line GNM treated by different levels of TGF-?1. Results: TGF-?1 showed different effects on the two cell lines. TGF-?1 significantly increased the expression of C-myc,CerbB2 and slightly enhanced TGF-?1 and EGFR protein expression in GNM cells, while TGF-?1 decreased the expression of C-myc,C erbB2,TGF-?1 and EGFR in TSCCa cells; moreover, the changes of protein ex pression of C-myc,CerbB2 were dose-dependent on TGF-?1. Conclusi on: TGF-?1 have different role in the oral squamous cell carcinoma cell lines.

Objective To express human chemokine-like factor 1 (CKLF1) in Drosophila S2 cells and study its function. Methods The pMT/V5-His-CKLF1 expression plasmid was constructed and transfected into Drosophila S2 cells. The positive clones were selected through PCR and RT-PCR. The culture medium was analyzed by Western blot with anti-CKLF1 polyclonal antibody. Chemotaxis and MTT assays on human peripheral blood and C2C12 cells, respectively, were then carried out with the medium. Results CKLF1 was transcribed efficiently in S2 cells. The expressed CKLF1 protein could be detected in the culture supernatant by Western blot, which showed weak chemotactic activity on both human peripheral blood neutrophils and lymphocytes as well as enhancing effect on the proliferation of C2C12 cells. Conclusion CKLF1 was expressed successfully in Drosophila S2 cells and secreted into the culture medium. The recombinant CKLF1 expressed in Drosophila cells can chemoattract leucocytes and promote the proliferation of C2C12 cells.
