Effects of Polygonatum sibiricum Polysaccharides (PSP) on Human Esophageal Squamous Cell Carcinoma (ESCC) via NF-κB Signaling Pathway

Figure 2

The proliferation of esophageal squamous cell carcinoma Eca109 cells was inhibited by PSP. (a) The toxicity of different concentrations of PSP on Eca109 cells (culture for 48 h) measured with CCK8, compared with the control group, ; . (b) The toxicity of PSP on Eca109 cells after different durations (200 μg/mL PSP) measured with CCK8, compared with the control group; . The proliferation of Eca109 cells in each group measured by CCK8 assay. Compared with the control group: and .
