HOXA10 and gastric cancer: To further investigate the functional role of HOXA10 and select appropriate cell lines for knockdown or overexpression in GC cells, qRT‐PCR and western blot were conducted to detect HOXA10 expression level in the following GC cell lines: BGC‐823, HGC‐27, SGC‐7901, AGS, NCI‐N87, KATO‐III, MGC‐803, and normal gastric mucosae cell line GES‐1.
