(A) Relative expression level of PPIA. (B) Evaluation of PPIA knockdown efficiency in A549 and NCI-H1975 cells with four experimental groups (si-NC, si-NC + pCMV-C-Myc, si-PPIA, and si-PPIA + pCMV-C-Myc). (C) Western blot analysis and quantification of PPIA protein levels in the same groups. (D) Quantification of PPIA protein levels based on Western blot results in A549 and NCI-H1975 cells. (E) Immunohistochemistry of PPIA in tumor and adjacent normal tissues.
