Fig. 2. Aspirin regulates the expression and phosphorylation of multiple molecules related to tumor progression.

Fig. 2

Cells were treated with 4 mM aspirin or control solution for 48 h, then harvested for subsequent western blotting. a Effects of aspirin on the expression of proteins associated with the cell cycle (P21, P27, and the phosphorylation of Rb and CDK2). b Effects of aspirin on the phosphorylation of AKT, MEK, and ERK, which regulated the activities of Ras/Raf/MAPK and PI3K/AKT pathways. c Effects of aspirin on the expression of proteins related to cell metabolism (c-Myc, PKM2 and LDHA). d Effects of aspirin on the phosphorylation of AMPK, 4EBP1 and P70S6K, which related to the activity of AMPK/mTOR pathway. e Effects of aspirin on the expression of COX2 and IL-1β, which related to immunoregulation. Error bars represent the means of three independent experiments. *P < 0.05, **P < 0.01, ***P < 0.001, NS no significance.
