The expression of PPAP2C in LUAD was analyzed using data from The Cancer Genome Atlas database. Pearson's correlation coefficient analysis was used to assess the correlation between PPAP2C and genes such as MAPK1, MAPK3, MAPK8, CDH1, CDH2 and SNAI1.

The results showed that PPAP2C was significantly upregulated in LUAD tissues compared with that in normal tissues. In addition, high levels of PPAP2C were significantly correlated with MAPK3, MAPK8, CDH1 and SNAI1. Notably, PPAP2C silencing significantly inhibited cell migration and invasion. Additionally, it reduced the phosphorylation levels of ERK and JNK proteins. PPAP2C showed specific binding sites with ERK1, and co‑precipitated with ERK1 in both A549 and H1299 cells. Furthermore, PPAP2C silencing decreased the expression levels of N‑cadherin and Snail, while increasing E‑cadherin expression, thereby inhibiting EMT.
