ABSTRACT
Objective To study the effect of a diterpenoid 5F (ent-11?-hydroxy-15-oxo-kaur-16-en-19-oic acid) isolated from Pteris semipinnata on the expressions of NF-?B (P65), Smad3 protein and NF-?B (P65), ETS-1 mRNA, and to investigate the antitumor mechanisms of 5F. Methods MTT assay was used to examine the effect of 5F on proliferation of HO-8910PM cells. The expressions levels of NF-?B (P65) and Smad3 proteins were assessed by Western blot analysis. RT-PCR assay was used to assess the expression levels of NF-?B (P65) and ETS-1 mRNA. Results The proliferation of HO-8910PM cells can be inhibited by 5F in a dose-dependent manner. The expression levels of NF-?B (P65) and Smad3 proteins decreased obviously in HO-8910PM cells after treatment with 25—100 ?mol/L 5F for 24 h, and the effects appeared in a dose-dependent manner. 5F down-regulated significantly the expression of NF-?B (P65) mRNA, down-regulated gently the expression of ETS-1 mRNA. Conclusion The antitumor activity of 5F is involved in the expression of NF-?B (P65), Smad3 protein and NF-?B (P65), ETS-1 mRNA.
