Transcriptional expression of ERBB2d16 and ERBB2 in gastric cancer. (A) The schematic structure of the ERBB2d16 protein; (B) The transcriptional expression of ERBB2 and ERBB2d16 by quantitative RT-PCR in gastric cancer tissue with beta-actin as an internal control (n = 110); (C) The ratios of the ERBB2d16/ERBB2 in HER2-positive gastric cancer tissues (n = 110). (D) An ERBB2d16/ERBB2 ratio-dependent expression pattern of ERBB2d16 relative to ERBB2 expression. Δ16 low: ERBB2d16/ERBB2 ratio < 0.88; Δ16 high: ERBB2d16/ERBB2 ratio ≥ 0.88. ERBB2: human epidermal growth factor receptor-2; ERBB2d16: ERBB2ΔEx16; RT-PCR: reverse transcriptive polymerase chain reaction.
