Abstract
AIM: To investigate the effects of Genestein on the expression of Akt and its phosphorylated proteins (p-Akts) in human gastric carcinoma cell line SGC-7901.
METHODS: SGC-7901 cells were exposed to 0、5、10、20、40 and 80 μmol/L Genistein for 24 h. The effect of Genistein on cell proliferation was measured by methyl thiazolyl tetrazolium (MTT) assay, and the apoptosis of SGC-7901 cells was evaluated by Hoechst 33342 staining. The expression of Akt and p-Akts (Ser473 and Thr308) were measured by Western blot.
RESULTS: The inhibitory rate was 6.85% ± 3.71%, 13.19% ± 1.90%, 20.94% ± 1.83%, 29.58% ± 1.19% and 41.75% ± 1.92%, respectively, as SGC-7901 cells were exposed to 5, 10, 20, 40 and 80 μmol/L Genistein for 24 h. Typical morphological changes of apoptosis were induced by Genistein at the concentrations (20-80 μmol/L). Genistein had no marked influences on Akt expression. Both Ser473 and Thr308 were expressed in SGC-7901 cells 24 h after Genistein treatment, and they were decreased with the increasing of Genistein concentrations. The weakest expression appeared as 80 μmol/L Genistein was used.
CONCLUSION: The anti-cancer action of Genistein may be associated with the decreased expression of p-Akt (Ser473) and p-Akt (Thr308).
