The results of the gentamicin protection assay revealed that PPR has the ability to prevent the invasion of HeLa cells by ST. (A) Screening process for inhibitors of ST invasion of HeLa cells. The concentration used in the screening assay was 100 µg/mL. (B) The ability of PPR to inhibit ST invasion of HeLa cells increased in a dose-dependent manner with increasing PPR concentration (n = 3). (C) Immunofluorescence analysis was used to detect the effects of PPR on ST invasion of HeLa cells (scale bar, 50 μm). The data are presented as the means ± standard deviations and were subjected to analysis via one-way ANOVA. NS, not significant; **p < 0.01.
