Also, CAI/BBR selectively showed anti‐tumor effectiveness in an ANO1‐positive GC PDX (Figure 3E) rather than in an ANO1‐negative GC PDX (Figure 3F), and were both valid to inhibit the growth of a GIST PDX model with medium ANO1 positivity (Figure 3G). The gene discussed is ANO1; the disease is gastrointestinal stromal tumor.
