Figure 8. mRNA expression of SERPINE2, FGF10, LSAMP, PDE5A in paired lung cancer tissues. (A) The bar plots showing expression levels of seven genes composing the CAFRS from TCGA- LUAD. The asterisks represent the statistical P values (***P < 0.001). (B–E) Paired dot plots show four differentially expressed genes composing the CAFRS, further detected by qRT-PCR in paired lung cancer tissues. (***P < 0.001).
