Immunofluorescence images and protein expression of the EMT-related indicators of HK-2 cells after BPS exposure. (A) Protein expression of EMT-related indicators in HK-2 cells after BPS exposure. (B) Down-regulated expression of E-cadherin and ZO-1 in HK-2 cells after BPS exposure, and up-regulated expression of α-SMA and Vimentin in HK-2 cells after BPS exposure. Scale bar, 50 μm. Data are showed as mean ± SD, and all experiments were repeated three times. **p < 0.01, ***p < 0.001, ****p < 0.0001 compared with control group.
