Comparison of PECAM1 mRNA levels in normal lung tissues and LUAD tissues across four analyses of LUAD. (A–D) Each study showed that the PECAM1 mRNA expression levels in normal lung tissues were significantly higher than those in LUAD tissues. (E) qRT-PCR analysis of PECAM1 mRNA expression in 47 pairs of LUAD tissues and adjacent nontumor tissues. (F) Kaplan-Meier curve of the relationship between PECAM1 mRNA expression and the prognosis of LUAD patients based on the TCGA database.
