Effect of compound 7g on the PI3K/AKT/mTOR signaling pathway. (A) SW620 and HT29 cells were treated with compound 7g for 48 h at different concentrations (0, 25, 50, and 75 μM). Cells were collected and harvested for protein lysates. The expression levels of PI3K/AKT/mTOR signaling pathway related proteins (PTEN, p-AKT, AKT, p-mTOR, mTOR, 4E-BP1, p-4E-BP1) were analyzed by western blot. Tubulin was used as a loading control. (B) The relative density of PI3K/AKT/mTOR signing pathway related-proteins was analyzed by the Tannon Gis Software. Each data point is the average of three independent experiments. Data were shown as the mean ± SD. * = p < 0.05; ** = p < 0.1.
