| Abstract: | AIM: To investigate the effect of PI3K/Akt signaling pathway on S100A6-induced proliferation and migration of human osteosarcoma cell line 143B. METHODS: Recombinant human S100A6 protein (rhS100A6) was prepared. The 143B cells were treated with rhS100A6 in the presence or absence of PI3K inhibitor (LY294002 or wortmannin) exposure. The final concentrations of rhS100A6, LY294002 and wortmannin were 30 mg/L, 10 μmol/L and 0.5 μmol/L, respectively. The expression levels of total Akt (t-Akt) and phosphorylated Akt (p-Akt) in the 143B cells were analyzed by Western blotting. The cell proliferation and migration were determined by MTT and Transwell assays. RESULTS: rhS100A6 protein was successfully prepared, and significantly increased the proliferation and migration of 143B cells (P<005). rhS100A6 up-regulated the phosphorylation of Akt in 143B cells (P<005). Compared with rhS100A6 group, the level of p-Akt in 143B cells and the proliferation and migration of the cells were decreased in combined treatment group of rhS100A6 with LY294002 or wortmannin (P<005), where the proliferation rate at different time points dropped from 10.3% to 69.7% (P<005), and the migration rate dropped from 34.9% to 47.7% (P<005). CONCLUSION: To some extent, S100A6 promotes proliferation and migration of human ostersarcoma cell line 143B through PI3K/Akt signaling pathway. |
