The MAGP1 mRNA and protein levels of five GC cell lines (SNU5, MGC803, HGC27, AGS, MKN45) and normal gastric cell line (GES-1) were measured, and found that MAGP1 expressed higher in SNU5 and MGC803, and lower in normal gastric cell line (GES-1) compared to the most of cell lines, including SNU5, MGC803, AGS, MKN45 (Figure 6A). Here, MFAP2 is linked to gastric cancer.
