In contrast to gastric mucosa epithelial cell line GES-1, transcriptional levels of PAPPA2, MPO, MAGEA11, DEPP1, CPZ, and COLEC12 were higher in gastric cancer cell lines HGC-27, MKN-28 and AGS, with lower transcriptional level of CYTL1 (Figures 9A–G). The gene discussed is PAPPA2; the disease is gastric cancer.
