Correlation analysis among the expression levels of PRR11, N-cadherin, and EGR1. a Western blot analysis detecting the protein levels of N-cadherin and EGR1 after PRR11 was knockdown for 48 h. b Graphical representation showing a significant reduction of PRR11, N-cadherin, and EGR1 protein levels according to ß-actin baseline levels. c Co-localization of PRR11 and EGR1 in the same tissue samples. c-1 Co-negative expression of PRR11 and EGR1 in the same tissue sample. c-2 Co-positive expression of PRR11 and EGR1 in the same tissue sample. Original magnification is ×200. d Co-localization of PRR11 and N-cadherin in the same tissue sample. d-1 Co-negative expression of PRR11 and N-cadherin in the same tissue sample. d-2 Co-positive expression of PRR11 and N-cadherin in the same tissue sample.
