The obtained data revealed a significant decrease in EGFR Tyr845 in lnc191‐silenced ESCC cells, while the site of Tyr992, Tyr1148, Tyr1045, Thr669, and Ser1046/1047 showed modest phosphorylation change (Figure S4C, Supporting Information). The gene discussed is EGFR; the disease is esophageal squamous cell carcinoma.
