The transcript level of PRAL was suppressed in vivo and in vitro. (A) Four cases from late-stage patients were randomly selected and subjected to RT-PCR analysis. In each patient, the relative transcript level of PRAL in tumor tissues was significantly lower than in their adjacent non-tumor counterparts. * P<0.05, as indicated. (B) Normal lung epithelial cell line MRC-5 and 5 lung cancer cell lines (H-125, A549, 95D, NCI-H929, and H1975) were included to assess the expression of PRAL. * P<0.05, vs. MRC-5.
