Figure 4.
(a) Overexpression of PCBP4 protein in IMC-3PCBP4 cells was confirmed by Western blotting. GAPDH was used as a loading control. The quantified density of the blots is presented in the right panel. (b) The cell cycle population was observed using flow cytometry without stimulation. *P < 0.05. Error bars ± s.d. (c) The cell cycle population was analyzed using flow cytometry after cisplatin treatment (1 μg/ml, 48 h). *P < 0.05. Error bars ± s.d. (d) Apoptotic cells were confirmed using Annexin V after cisplatin treatment (1 μg/ml, 48 h). *P < 0.01. Error bars ± s.d. (e) Cell viability analyzed by MTT assay after cisplatin treatment (1 μg/ml, 48 h). *P < 0.05. Error bars ± s.d.
