Figure 6. CFF-1 inhibited PCa cells proliferation. (A) The colony formation efficiency of PC-3 cell lines with varying concentrations of CFF-1 (mg/mL). (B) The EdU assay of proliferation active cells after 24 hours of CFF-1 treatment. (C) Quantification of the colony formation efficiency with bar graph. (D) Quantitative results of the EdU assay with bar graph. (E) The cell viability was determined by CCK8 assay after CFF-1 administration. *p < 0.05, **p < 0.01, ***p < 0.001.
