To investigate the potential role of BCAM in GC cells, we first performed qRT‐PCR analysis and found that BCAM was upregulated at high levels in AGS, MKN‐45, and BGC‐823 cells, and low levels in SGC‐7901, MKN‐74, MGC80‐3, and HGC‐27 cells (Fig. S1A). The gene discussed is BCAM; the disease is gastric cancer.
