In addition, the Western Blot analysis was conducted to examine EMT associated biomarkers, and the results in Figures 5G–O supported that LncRNA MIR503HG inhibited N-cadherin and Vimentin expressions in GC cells without PERK and IRE1 expressions, but did not influence EMT in ATF6-deficient GC cells. The gene discussed is ATF6; the disease is gastric cancer.
