Figure 5. The effects of arginine depletion on the growth and migration of human MKN45 gastric cancer cells.
ASS1 knockdown cell clones were grown in culture medium containing 5% FCS. Two different medium conditions were used. Arg (-) indicates arginine-free medium. Cells were cultured for 24, 48, or 72 h. (a&b) Cell proliferation. (c&d) Wound healing. P: parental cells; VC: vector control; RNAi-1 and RNAi-2: ASS1-specific shRNAs 1 and 2, respectively. The results are expressed as the mean ± s.d. of three independent experiments. NS, not significant, **P < 0.001, ***P < 0.0001.
