Polyphyllin I Inhibits Propionibacterium acnes-Induced IL-8 Secretion in HaCaT Cells by Downregulating the CD36/NOX1/ROS/NLRP3/IL-1β Pathway

Figure 4

PPI inhibiting proliferation and migration of HaCaT cells. (a) The proliferation of HaCaT cells following P. acnes treatment with PPI (0.9 μg/ml) or 01% DMSO exposure detected by the EdU incorporation assay. The red color represents EdU positive, and the blue color represents DAPI (nucleus). The average ratio of EdU positive HaCaT cells is calculated by ImageJ. (b) The migration of HaCaT cells following P. acnes treatment with PPI (0.9 μg/ml) or 0.1% DMSO exposure detected by the transwell assay. (d) The average number of migrated HaCaT cells calculated by ImageJ. n = 5/each group. vs. control group. vs. P. acnes treatment group.
