The expression of SRC and MYOF in both Ace-1 and Ace-1-huGRPr cells before and after addition of 1 nM bombesin (BBN) for different time periods (0, 30 min, 1, 3, 6, and 24 hr). Significant differences are indicated as: *P≤0.05, **P≤0.01, ***P≤0.001, and ****P≤0.0001 different from control Ace-1 or Ace-1-huGRPr cells.
