Additionally, Western blot analysis of six GC cell lines, including BGC-823, MKN-45, 7901, AGS, MKN-28 and MGC-803, exhibited increased levels of HOXB7 in comparison to the normal gastric mucosa cell line GES-1, and among the six GC lines, the HOXB7 expression was the lowest in MGC-803 and the highest in BGC-823 (Figure 1D). This evidence concerns the gene HOXB7 and gastric cancer.
