Figure 4. Effect of NT21MP on PR cell biological activity.

(A), Sulforhodamine B assays were performed to measure the proliferation in PR cells treated with NT21MP. (B), Wound healing assays were used to detect the motility in PR cells treated with NT21MP. (C), Invasion assays were conducted in PR cells treated with NT21MP. (D), Flow cytometry was used to evaluate the cell cycles of PR cells after treatment with NT21MP. (E), Apoptosis was detected in PR cells after treatment with 1 μg/mL NT21MP. *P < 0.05, PR vs control; #P < 0.05, NT21MP treatment vs control in PR cells.
